Meeting the Growing Demands of a Successful Mining Operation – The Schwing Bioset Solution

 

Written by Miguel Jahncke, May 2, 2016

The San Jose mine, one of the flagship operations of Fortuna Silver Mines, Inc., located in the state of Oaxaca in Mexico, was commissioned in July 2011 and began commercial production in September 2011 at a rate of 1,000 tpd. In September of 2013, the mill was expanded from 1,150 tpd to 1,800 tpd and in April 2014, the mill was further expanded to 2,000 tpd. Expansion of the mill from 2,000 tpd to 3,000 tpd was initiated in the first quarter of 2015 with commissioning planned for July 2016.

During the initial installation, the operation received two Schwing Bioset KSP80 pumps, one for operation and one for stand-by. As the reserves increased and the mine production and processing plant expanded, San Jose evaluated different options for handling the additional mine backfill requirement, finally deciding upon the reconfiguration of the KSP80 pumps and their installation at the new and improved Paste Plant, in a parallel arrangement. This new arrangement allows San Jose to handle double their initial paste flow capacity with no additional investment in larger pumps.

In addition to the parallel arrangement, Schwing Bioset also upgraded the Control Panel with its patented multi-pump synchronization system. This system allows both pumps to continuously “talk” and make adjustments to their stroke timing while pumping, ensuring that, regardless of the pump speed, continuous flow through the pipeline is achieved, mitigating the potentially negative effects of water hammer. 

The new system was recently commissioned and now operates as a single 4-cylinder pump with no need for additional pipeline pressure dampening to maintain smooth pumping operations, as would be expected from multiple independent pumps feeding a common pipeline. The configuration also allows for the units to be decoupled for maintenance or when plant tailings delivery is reduced, continuing operation with two cylinders to maintain the single pump flow capacity.

Further proving their versatility and toughness, the Schwing Bioset pumps were the only component that was saved from the old Paste Plant to be reutilized in the new Paste Plant. Upon completion of the 3,000 tpd expansion, the mine will produce 9-10 million ounces of silver and 52,000-53,000 ounces of gold per year, ranking the San Jose Mine among the world's top-13 primary silver producing mines.

Bioset Demo Confirms Direction for New Class A Biosolids Equipment at Russellville WWTP

 

Written by Lance Bartlett, Utility Engineering Manager for City Corporation and Tom Welch, Southeast Regional Sales Manager for Schwing Bioset, Inc.

April 25, 2016

 

In early 2015, City Corporation, the commission established by the City of Russellville to operate the municipal water system, completed a construction project to abandon existing fixed film treatment facilities and convert the wastewater treatment plant to a denitrifying activated sludge facility.  Activated sludge technologies produce more sludge than fixed film and initial calculations predicted an increase of 6 to 7 times the current production rate when operated at the design capacity of the facility.

City Corporation had processed sludge through aging aerobic digesters and produced a Class B biosolid under 40 CFR 503 that was then dewatered and land applied to three nearby fields.  Two of the three permitted fields were no longer available, leaving only 49 acres for use.  The increase of sludge production was predicted to require around 160 acres.

The expected increase in sludge production and lack of land available for land application prompted staff to explore options.  The alternatives explored included composting, additional aerobic digesters, dryers, and the Bioset process from Schwing Bioset, Inc. (SBI). The Bioset process was selected for piloting in February and March of 2015 due to its low cost, simple operation, and the high quality Class A product that it produces.  The lone concern was with respect to the increase in volume due to the addition of chemicals, and staff wanted to get the new process up and running to obtain empirical data on sludge volume.  The engineering firm performing the preliminary study had built in a large contingency due to not being familiar with the Bioset technology and the uncertainty in sludge volume, thus raising concerns that the Bioset technology would be the proper process for the future of the Russellville WWTP.  Ultimately the volumetric increase was less than 10%, and with the Class A designation the number of outlets and demand for the material exceeds production rates.

Russellville_Bioset_3.jpg Russellville WWTP_Bioset Process_Schwing Bioset

Following that successful pilot test, in April of 2015, Schwing Bioset agreed to continue to lease the pilot machine under a monthly contract basis for the sludge handling process.  By the fall, City Corporation had a good feel for their solids production and had a great experience with the Bioset full scale pilot equipment.  Given the years of struggling with the Class B sludge process, management and staff were very pleased with the Class A process and end product and the thought of returning to a Class B process was taken off the table. With all the uncertainty taken out of the equation, staff was ready to make a decision and chose to move forward with a permanent Bioset installation.  City Corporation and Schwing Bioset continue to operate under a contract that allows City Corporation to operate the pilot unit until the permanent unit is installed and operational.  This arrangement allows City Corporation to manage their sludge and operate the plant in accordance with the design parameters, keeping the facility in compliance with the ADEQ, which otherwise would not be possible.  The new facility is anticipated to be operational in mid-October 2016.  The current digester will only be used as a sludge holding tank, thus reducing the power consumption needed for complete aerobic digestion to meet Class B standards, and allowing just WAS sludge to be converted to Class A EQ fertilizer through the Bioset process.

Phosphorus Removal and Nutrient Harvesting Continuing Education

 

Written by Eric Wanstrom, March 22, 2016

Schwing Bioset is pleased to announce the Schwing Bioset Phosphorus Removal and Nutrient Harvesting paper has received accreditation and official approval for continuing education credits in New York State.  

Schwing Bioset’s Nutrient recovery system recovers Ortho Phosphate and Ammonia Nitrogen from wastewater while offering great benefits to the treatment plant, not only by significantly reducing phosphorus in the waste stream, but also preventing unwanted scaling and accumulations, and creating a valuable end product.  The phosphorus forms a stable Struvite crystal that can be marketed and sold for beneficial reuse, thus keeping excess phosphorus out of the local waterways and helping close the phosphorus recycling loop.   

Engineers and operators can receive one (1) hour of CEU credits for attending a presentation on these topics.  Please contact us to schedule the presentation for your office or plant.

Solving Several Challenges with One Schwing Bioset Solution

 

Written by Miguel Jahncke, March 10, 2016

In late 2012, Volcan Compania Minera S.A.A.’s Victoria mineral processing plant, located in the Yauli district, department of Junin in Peru, was facing a number of challenges including the approval of their Environmental Impact Statement for the capacity expansion from 2,400 to 4,000 tpd of ore.

The project also required the expansion of the Rumichaca Tailings site to accommodate the increased production levels. Pumping thickened tailings, rather than conventional tailings, was determined to be the best long-term and financial solution to handle the mining rejects. The project continued to evolve in that direction. 

In mid-2014, when the final solution for the thickened tailings transport was being evaluated, it was determined that the solution offered by Schwing Bioset, its model KSP440 piston pump, was ideal for the project for the following reasons:

  • The KSP 440 unit is capable of the required maximum flow of 185 m3/hr as well as reduced flow of 92 m3/hr when at low plant production rates, which is expected at certain times by idling a module within the pump.
  • Half of the pump can be idled while half continues to operate allowing for preventive maintenance to be performed while operations continue at a slower pace or to accommodate unscheduled downtime.
  • Elimination of additional and costly stand-by equipment, with the modular pump arrangement.
  • Drastic reduction of water hammer in the discharge line without the use of Pulsation Dampeners through PLC synchronization that monitors and adjusts the timing of the pumping strokes.
  • Electric motor and hydraulic redundancy in the power pack allowing partial capacity in the event of unscheduled maintenance.

Pressing Issues (for Water Treatment Plant)

 

Published in WaterWorld Magazine, February 2016. Written by Larry Trojak.

When a new plant that Davidson Water Inc. (Lexington, N.C.) had recently inaugurated started producing levels of solids almost double what it had anticipated, the company worried that all its advance planning was for naught and the dewatering facet of the process was doomed. However, one of the key components in that effort, a new screw press, met the challenge, giving plant operators the results - and the peace of mind - they needed.

Heat Integration – Opportunities and Concerns

 

Written by Joe Scholl, February 11, 2016

The word “heat” may be defined as the amount of energy that is transferred from one system to another, typically via a temperature differential or “gradient,” and the amount of heat something possesses may be stated in terms of British Thermal Units (BTU), Joules (J), calories (cal), etc. (as compared to reference temperature or datum state).  Measured over time, heat becomes energy that is used to accomplish tasks, and that energy may be measured in BTU/hr, J/sec, etc.  There is a definite cost to energy usage, as evidenced by any plant’s energy utility bill.  As such, there is a high emphasis nowadays in energy re-use (“heat integration”) via applying “waste” heat from one process to another process needing energy.  While many such heat/energy integration techniques may be easily accomplished, there may, under certain circumstances, be limitations to the extent such energy re-utilization efforts may be accomplished.

Many municipal wastewater treatment plants (WWTP’s) are utilizing anaerobic digestion systems and these processes may produce digester gas or “biogas” (chiefly methane and carbon dioxide with other trace chemical constituents and/or contaminants).  The biogas produced may be used by a variety of means, such as for maintaining heated conditions in the digester units and/or in gas engines that drive generators to produce electricity in a combined heat and power cycle (CHP).  These CHP processes generally produce two “waste” heat streams by which heat may be extracted and re-utilized (i.e. “integrated”) in another process.  These two streams are the exhaust (or “stack”) gas from the biogas combustion process itself and a hot water stream (typically a water/glycol mixture) or steam produced from using cooling water to maintain reasonable CHP engine temperatures. 

The extent to which these particular waste heat sources can be utilized depends on many factors, including the costs associated with purchasing, installing, and operating the heat recovery equipment.  With respect to utilizing a waste heat source in a sludge thermal drying operation, some of these factors may include:

  • How close to the drying system is the heat source? Specifically, what are the fluid movement costs from point A to point B, in terms of liquid pumping or gas handling requirements and how does this impact the overall heat integration strategy?  
  • What is the additional capital expenditure (“Capex”) requirement to install insulated piping or ducting from the source to the drying system and are these Capex requirements so high that the payback to incorporate the waste heat into the drying system result in an unreasonably long payback period? 
  • Are long-term corrosion issues a concern, such as materials of selection for digester gas piping, stack gas ducting, etc. (especially if “acid gases” condense-out of the gas stream upon cooling, leading to corrosive conditions within the piping, ducting, or heat transfer equipment) and, if so, what is their Capex impact, as well operating expense (“Opex”) impact (e.g. will long-term corrosion issues require long-term maintenance expenses)? 
  • How much heat will the waste heat stream lose from point A to B and will this heat loss drive the heat recovery economics toward an unfavorable overall result? This point is particularly important if the waste heat stream is steam, where the latent (or condensing/phase change) heat of the steam is the primary (or desirable) heat transfer mechanism.  For example, if the waste steam loses sufficient energy in transit from its source to the drying system, will the steam lose so much heat that it condenses to liquid form, thereby “robbing” the heat integration scheme of the steam’s latent/condensing heat prior to the drying system (noting that the latent/condensing heat of steam is significantly higher than the specific heat capacity of either the steam or liquid forms)?

In general, there are many possibilities for incorporating waste heat into a thermal drying process.  However, the costs (in terms of Capex and Opex considerations) to incorporate the heat integration step must also be considered to determine whether doing so is practical.

How Transitioning to Class A Biosolids Saves Money

 

Published in TPO Magazine, February 2016. Written by Larry Trojak.

 

A southwest Florida treatment plant turns to lime stabilization to create Class A biosolids for land application and cuts handling costs significantly.

Cost-effective handling of biosolids is essential to clean-water plants’ economic and environmental performance.

The Immokalee Water and Sewer District in Florida faced a biosolids challenge in 2006. The district had been using drying beds to create Class B biosolids and spending about $500,000 a year to dewater and haul excess material from that process to a landfill.

Facing a change in regulations on land application of Class B material, and wanting to reach the biosolids’ full economic potential, the district looked at alternatives. The ultimate solution was a facility redesign centered on using the Bioset process (Schwing Bioset) to create Class A biosolids. As a result, the district has reduced handling costs by more than two-thirds and produces a Class A product for beneficial use.

Anticipating change

Located about 30 miles southeast of Fort Myers, the heavily agricultural Immokalee district is home to about 24,000 residents. Its wastewater treatment plant was expanded in 2013 from 2.5 mgd to 4.0 mgd design capacity. Until fairly recently, it generated 23,500 gallons of Class B biosolids per day at 1 to 1.5 percent solids.

Gary Ferrante, P.E., an engineer with the Greeley and Hansen engineering firm, says a number of factors in 2006 led the district to review its biosolids operation. “Immokalee’s plant was originally designed with a half-dozen drying beds in which a Class B biosolids was created and used on permitted area farms,” he says.

“While that was effective, the facility is next to a school, which repeatedly complained about students’ health risks and odor. The district later learned that the U.S. Department of Agriculture and the Florida Department of Environmental Protection were considering changes to biosolids land application regulations (passed in 2010 as Florida Biosolids Regulation Chapter 62-640 F.A.C.). All that prompted the district to hire a consultant to look at alternatives.”

Lots of options

Based on recommendations from the consultant’s report, in 2007 the district contracted with Synagro Technologies to dewater the Class B biosolids and haul it to a landfill more than 100 miles away. In time, rising prices and an increase in biosolids volume raised annual costs from $309,000 to more than $470,000, providing incentive for the district to pursue other options.

“Working with the district, we put together a couple of proposals and a couple of scenarios within each proposal,” says Ferrante. “The first one covered the design/build/finance of a biosolids facility at the existing location. Options under this plan included handling material from Immokalee only, as well as accepting material from Collier County and making Immokalee a regional processing facility. The second proposal had an outside entity leasing land from the district and constructing a Class A regional processing facility on it.”

An option under that proposal included a continuation of the contract dewatering program while the regional facility was taking shape. In the end, the district chose to establish a turnkey processing facility for its own biosolids sludge only and selected the Bioset process to deliver Class A material.

Class A operation

At the new facility, material exits the primary treatment facility’s sludge holding tanks at 1.5 percent solids and is fed directly to a high-performance screw press, selected for a number of reasons, including its relatively compact design.

“Because of the limited availability of usable land, a small footprint for the entire biosolids system was a major consideration, and the Bioset screw press fit in nicely,” Ferrante says. “We’ve found it to be an outstanding dewatering tool, yet extremely efficient in power usage.

“The belt press we looked at would have taken the material from 1.5 or 2 percent solids up to 8 to 10 percent. A centrifuge might get that up to 20 percent, but the electricity costs would be much higher. The screw press takes the material up to 16 percent solids. It uses twin augers and a changing pitch on the screws to advance the material and remove the water. Because it takes far less energy to turn those two screws than to power a centrifuge, the savings in power consumption can be significant.”

Another feature is that district personnel can wash the screw press down while it remains operational, says Michael Castilla, service technician 1: “The Bioset screw press has an automated self-cleaning function which in itself is nice. However, when we have a situation that calls for additional cleaning, we can simply push a button and a cleaning cycle will start. That’s a bonus. To shut a press down for maintenance or repair could cost us a half-day’s performance.”

Positive reaction

After dewatering, untreated biosolids are taken via screw conveyor to a twin-screw mixer in which quicklime and sulfamic acid are added. The mixing resolves issues such as unreacted lime in the final product and yields a highly homogeneous material. From the mixer, a Schwing Bioset KSP-10HKR pump feeds material into a 56 1/2-cubic-foot reactor in which heat from the acid and quicklime reaction raises the pH, stabilizing the mixture and creating a product that meets both Florida Chapter 503.33 and U.S. EPA Class A requirements.

“Retention time in the reactor is about 30 to 45 minutes at temperatures in the range of 122 degrees Fahrenheit,” says Ferrante. “The plant wastes sludge for 16 hours a day, consistently generating about­­­­­ 11 dry tons of the Class A material weekly and doing so at a markedly lower cost than for outright hauling and landfilling.”
Castilla adds that the system’s ease of operation was also key to getting up to speed quickly.

“It is very intuitive and simple to operate,” he says. “However, Schwing Bioset still went to great lengths to ensure that people involved in day-to-day operation are comfortable with it, have a handle on the maintenance routines, and so on. Ian Keyes from their Wisconsin office spent time here mentoring me to such a degree that there’s very little about the system I don’t understand.”

The Class A material exits the system, is loaded onto a manure spreader and taken to an area field where it is applied in place of fertilizer. Eliminating those fertilizer costs alone has saved about $50,000 per year.

In addition to lower costs, the district benefits from a much cleaner, less maintenance-intensive, more environmentally friendly operation. Dust from the lime-based process is controlled using hard-piped or totally enclosed components. Odorous air is contained by the pressurized reactor and then captured and scrubbed under a collection hood before release.

Room to grow

The district’s biosolids plant was designed with ample space to install a second identical processing line in case the regional concept becomes a reality. “One of the most important aspects of this system is its ability to accommodate the changes a regional operation would entail,” says Ferrante. “Things like fluctuations in the percentage of solids, increases and decreases in throughput, and compatibility with biosolids from aerobic or anaerobic digestion processes without modification, are all within its design capability.

“Simply put, the district is well positioned to have its wastewater treatment needs met for the foreseeable future. After the $2 million design/build/finance contract was awarded, the district, seeing itself in a good financial position, opted to pay that cost out of pocket, rather than financing it over 20 years.”

The annual operating cost for the new system is about $130,000 a year, including chemicals and electricity. With estimated savings of $370,000 per year over landfilling, the system will pay for itself by about mid-2019.

“This was a case in which Immokalee, a small independent special district with a serious financial headache, took real initiative in getting things done,” says Ferrante. “They will be the beneficiaries of those sound decisions for decades to come.”

Schwing Bioset Releases New Struvite Recovery Technology Brochure

 

Written by Chuck Wanstrom, January 22, 2016 granual_cup-transparent-SBI_logo.jpg

To support its marketing efforts of the NuReSys struvite recovery technology in North America, Schwing Bioset, Inc. is pleased to release its new brochure that discusses the benefits to plant operations utilizing its technology.  The brochure also includes specific operational features and shows several possible configurations of the process which are meant to solve various issues encountered by Municipalities.

At plants utilizing anaerobic digestion, Struvite commonly forms and creates issues with pipes clogging and equipment being damaged as a result of scaling.  Additionally, tanks can accumulate Struvite, which requires periodic removal and creates an additional expense to plant operations.

“By utilizing Schwing Bioset’s Struvite recovery technology, rather than the other “one-size-fit-most” solutions currently available, these specific plant operational issues are addressed, while at the same time reducing the load of phosphorous that is returning to the head of the plant, making it easier to meet ever strict discharge limits,” said Chuck Wanstrom, Director of New Business Development at Schwing Bioset.  Coupled with the capability of recovering one of nature’s most essential and limiting nutrients to sell in the fertilizer market makes the technology appealing to a wide range of Utilities. 

Solve operational issues, reduce phosphorous loads within the plant, and upcycle your waste stream to make your facility a true Resource Recovery Center - all from the name you can trust, Schwing Bioset.

Please download a copy of the new brochure now and contact us to answer any questions and see how struvite recovery may be the right solution for your plant.
