City of Orlando WWTP Utilizes Schwing Bioset Piston Pumps in Class AA Process

 

City of Orlando, FL, Conserv II WWTP Utilizes Schwing Bioset KSP 25 Piston Pumps in Class AA Biosolids Process

Written by Tom Welch, December 14, 2016

The City of Orlando, FL, Conserv II WWTP became aware of the Schwing Bioset process and immediately saw the potential it had to meet all of their requirements for both short and long-term implementation.  In addition, Schwing Bioset could offer conversion of the stabilized Biosolids to a licensed commercial fertilizer product.  The City staff visited current Bioset operations in Florida and were impressed with what they saw and with the simplicity of the process.  The City conducted an in-house feasibility study that considered Bioset and other technologies and concluded that Bioset was the preferred treatment process.

The current dewatering facility has four belt filter presses that discharge onto two belt conveyors that converge onto one common belt conveyor that takes the dewatered Biosolids to truck loading.  The decision was made to move away from the common belt conveyor to make the process more robust.  A KSP 25 piston pump was added at the end of each belt conveyor.  The two pumps are utilized to transfer the dewatered cake to the Bioset (Class A alkaline process).  The Bioset process also utilizes a third KSP 25 pump as the heart and soul of the system to blend the chemicals needed for the Class A process and pumps the end product into a plug flow reactor and ultimately out to two truck loading areas.  These pumps are programmed to work together to make sure that a consistent flow of Biosolids can be treated to Class A status through the reactor.

Sliding Frame Silos Help Treatment Plant Produce More of a Good Thing

 

Written by Eric Wanstrom, December 1, 2016

Ocean County Utilities Agency (OCUA) had been producing OCEANGRO fertilizer with Biosolids from their Central Treatment Plant with great success.  Currently, every bag of OCEANGRO produced is sold in the community.  Ocean County looked to increase the production of OCEANGRO to meet the increasing demand by using Biosolids from their North treatment plant.  This posed several challenges though: How would they get the Biosolids into the trucks at the North Plant?  How would they get it out of the trucks at the Central plant?  Once there, how would they blend the stream of the two differing Biosolids to make the uniform blend of material required by their Biosolids dryer? 

Ocean County Pump.jpgSchwing Bioset was able to work with Ocean County to provide a solution to the challenges of loading, receiving, and blending the Biosolids.  Schwing Bioset manufactured a custom designed storage silo with a sliding frame feeder at the North plant, designed to load trucks with Biosolids.  This silo would store the Biosolids and rapidly feed it into the trucks, but first the biosolids would have to get there from the new Belt filter presses, a distance of roughly 300 feet.  So, Schwing Bioset supplied high pressure piston pumps rated for 100 bar line pressure to pump the biosolids from the dewatering collection area to the top of the truck loading silo.

Ocean County Storage Silo.jpg

At the Central plant, there are two sliding frame silos to receive the biosolids coming from the North plant.  The sliding frames easily feed the material to the close-coupled pumps and can even push small rocks and tramp material that might make their way into the trucks or bins.  The silos are equipped with covers to contain odors from the biosolids and are large enough to each receive a full 25-ton truck load of cake.  The two storage silos provide ample capacity, allowing Operators at the Central plant to meter the North biosolids feed with the feed from the Central plant and provide a uniform blend for pressing the OCEANGRO fertilizer.

The silos give Ocean County Utilities exactly what they needed, the ability and the flexibility to process the additional biosolids from the North plant at the rate needed to keep production running smoothly at the Central plant, while accomplishing the goal of increasing the amount of biosolids beneficially re-used as OCEANGRO fertilizer.

Sliding Frame Truck Loading Reliability at Puyallup, WA, WWTP

 

Written by Joshua DiValentino, November 14, 2016

The City of Puyallup, WA, wastewater treatment facility has implemented a series of strategic upgrades. Significant improvements were made to the Biosolids Facility. One major long term issue was not just biosolids cake storage capability, but also consistent truck loading. The 8 MGD facility does not have a large maintenance/operations staff, so they were searching for “set-it and forget it” type equipment.

The Puyallup facility considered several options to meet their needs, including traditional live bottom systems. The more traditional options did not offer ease of use for consistent repeated truck loading without additional operator support. The traditional route was also not found to be as layout-friendly and consisted of additional moving parts, which would also require more maintenance attention. These factors increased the strain not only on the design, but also on the long-term manpower required to run a future truck loading system.

Selection of the Schwing Bioset sliding frame is attributed to its ability to overcome many of the concerns noted above. The system offers the desired storage capacity of 170 cubic yards, as well as the loading consistency needed. A truck driver is able pull into the loading bay initiating gates to open and fill the truck at multiple points. The system is also integrated to control the metering of Biosolids into each truck and uses load cells as part of the automated loading sequence, in order to avoid overfilling and putting overweight trucks on the highway.

The Sliding Frame offers this capacity from the lowest profile design and the system’s vertical side walls maximize usable space. This profile allowed the system to be built immediately next to the solids build and still accept the conveyor feed system, which originates from a floor below.

This is all accomplished from a system with the fewest wear parts of any comparable system on the market. Only bi-annual inspection and tightening of rope packings and changing of drive system filters are required for regular maintenance. Schwing Bioset has proudly installed nearly 100 of these systems in North America, and Puyallup is the first in Washington State.

Replacing Failing Filter Press Yields Huge Improvements

 

Schwing Bioset Application Report 22, Seneca Water

Written by Larry Trojak, Trojak Communications

Version also published in WE&T Magazine, October 2016 Issue

 

When the Seneca (S.C.) Water Treatment Plant embarked on a recent expansion project, its overall goals were fairly straightforward: eliminate the use of chlorine in purification, relocate its new chemical treatment process, and upgrade the alum sludge dewatering operation. On that last point, plant officials opted to replace an outdated and difficult to maintain batch filter press with a different technology altogether — a fully-automated screw press — to handle its dewatering needs. In doing so, they not only eliminated an ongoing maintenance headache, they also dramatically improved the efficiency of their dewatering operations as well as their overall residuals management operation.

 

Water for Sale

Built on a hill overlooking Lake Keowee, the Seneca Water Treatment Plant is a 20 million gallon per day (MGD) facility located in Seneca, South Carolina, that serves more than 39,000 residents in and around Oconee County in the far northwestern part of the state. According to Steve Fletcher, the lake is owned by Duke Power Company, which allows the City to draw raw water for municipal purposes.

“As part of the agreement with Duke Power, we take in and treat the lake water, then, once purified, wholesale it to area communities,” he said. “That 20 MGD number is our peak permitted flow — our actual volumes vary, but are generally in the seven to 10 MGD range.”

Storage facilities for the treated and purified water currently consist of three ground storage clear wells and eight elevated tanks with a total capacity of 6.5 million gallons.

Risk Management

Until this latest expansion, water disinfection was done using chlorination which, while effective, was seen as a serious potential hazard, said Fletcher.

“When this plant was first built in 1968, there was literally one house in the immediate area,” he said. “However, the lake’s popularity has attracted large-scale development — both residential and commercial — and today the area immediately around the water plant is dense with some very nice homes. Should one of our three one-ton cylinders of chlorine gas have ruptured, it could have seriously affected people for a mile around the plant. We didn’t want to risk that any longer and decided that generating our own sodium hypochlorite was a much safer alternative.”

In addition to the change in chemical process, the expansion also resulted in a brand new operations building which houses not only the offices and administrative staff for the plant, but also includes a new laboratory facility and a common area that will be made available to city residents for meetings and other functions.

“This project really grew as we went along, as did the price tag which went from $3 million to $10 million.” Said Fletcher. “But we knew that, as long as we were making changes, we might as well make all the improvements we’ve talked about wanting for a long time.  Right now this is one of the most functional — and beautiful — water treatment plants around.”

 

Residuals Shortcomings             

Treatment of alum sludge at Seneca Water, the by-product of using aluminum sulfate as a coagulant, has a storied history. When the plant was originally built in 1968 there was no treatment effort at all; sludge was simply returned to the lake. The advent of clean water regulations changed all that and Seneca Water was soon recovering and disposing of its sludge in an area landfill. To dewater the material, Fletcher said the plant officials in about 1990 opted for use of a plate and frame filter press.

“Once installed, that press remained in place up to the recent upgrade and eventually became one of the main motivations behind a re-tooling of the sludge process,” he said. “I’m sure that, in its day, it was a solid performer. In recent years, however, it had become such a headache to maintain that it was a full-time job just keeping it operational. In addition, it ran as a batch process which meant it had to stop after every batch of dewatered sludge it created. We knew there were better solutions available out there and we started looking at them.”

It’s worth noting that the overall configuration of the alum sludge plant was sorely lacking as well. At the time, sludge was collected in the backwash holding basin, sent to a vertical turbine transfer pump, then routed up to a thickener.

“Unfortunately, that thickener was on the top of a hill on the other side of the plant,” said Fletcher. “Hardly the most efficient layout. Once thickened, sludge came back down the hill into a diaphragm pump and into the filter press. The transfer pumps were not only costly to run and almost always in need of rebuilding, they weren’t really designed to pump sludge so they were continually stopping up. All those things collectively got us thinking about ways to improve the overall biosolids process — starting with the press.”

 

Trials and Errors

After a fairly lengthy process of demos and trials, Seneca Water, working through their consulting engineer, chose a screw press from Schwing Bioset, Inc. Fletcher said the unit best met established criteria which were focused on cost versus performance.

“We looked at a number of manufacturers and a number of different technologies and knew that the Schwing Bioset unit would best meet our needs,” he said. “Our old press was taking in sludge with 4% to 5% solids and dewatering it to about 24% solids, so we were hoping for at least that. However, many of the presses we tested were giving us product in the 16% to 17% range — we definitely didn’t need a step backward. The team from Schwing Bioset brought their demo unit online and almost immediately we were getting dewatered sludge in the 28% to 32% range. Equally important, however, was the fact that the screw press was fully-automated rather than a batch-process design. That meant we no longer needed to have a man assigned to the press six hours a day, every day, as we’d done in the past.”

With Seneca Water committed to the Schwing Bioset screw press, additional changes were made to the alum sludge processing line, including the addition of a Model 300 large bubble mixer from Pulsed Hydraulics, Inc. (Oroville, Wash.).

“In the past, we’d had problems with the sludge settling and stagnating in some of the lower parts of the holding basin,” said Tommy Clayton, a Class A operator at the Seneca plant. “This PHi bubble mixer keeps the sludge moving and further increases production through the Schwing Bioset screw press. It has very low energy demands, has no other moving parts and runs off a compressor which we need for the press as well. The two are a perfect fit.”

Seneca Dewawtering Screw Press

 

Pressing Issues

The increase in production with the screw press in place was immediate and substantial. Because of the batch nature of the former plate and frame press, Seneca Water was forced to process sludge continuously all year long. According to Fletcher, that has changed with the addition of the Schwing Bioset unit.

“Now, with the continuous dewatering process we can have material being collected in the basins and, when ready, can get caught up in just two to three weeks. There really is no comparison between the two presses, but it’s safe to say that we can probably do close to two tons of alum sludge a day with the Bioset press while the old press took two days to do just a ton.”

Those old production figures were affected by both the cleaning process and by maintenance-related downtime. The plate and frame press, said Fletcher, had to be washed down after every batch — a process that could take as long as three hours. By comparison, the Bioset screw press has a self-cleaning function in which the screen gets sprayed — while the unit is in operation — cleaning it off.

“That means continuous production and no lost time, which is huge” said Fletcher. “We are saving no less than six hours a day in manpower alone just by nature of not having to have a man on the filter press handling the batch process, cleaning it and so on. However, without a doubt, we are benefiting most by finally having a press that is reliable — we are no longer having to constantly work to keep that unit operational. We simply start up the Schwing Bioset unit and it runs all day long.”

 

Working Together 

Once dewatered, Seneca’s sludge is collected and sent to an area wastewater treatment plant where it is mixed with that facility’s dewatered biosolids and trucked to a landfill in a collaborative city/county effort.

“There are so many facets of our operation that have been improved with this latest expansion,” said Fletcher. “We are much more efficient now, our process is better and far more reliable, and the risk of danger from chemical exposure has been eliminated. That’s a very nice turnaround for us and a benefit to the Seneca community as a whole. We couldn’t be happier with the way things turned out.”
