Another Successful Schwing Bioset KSP Pump Service Seminar is Complete


Written by Kelly Kramer

May 2017

Schwing Bioset, Inc. (SBI) held its Spring KSP Pump Service Seminar from May 9 – 11 in MN/WI. The seminar was our most well-attended seminar yet and, once again, led by Schwing Bioset’s Quality Control Specialist, Jack Koehler, and Service Technician, Chris Kohnen. The seminar and training is designed for Schwing Bioset customers to expand their knowledge on how to properly use and maintain their equipment, to help ensure they get the most out of it. This spring, there were 23 customer attendees and three of Schwing Bioset’s employees who attended. The course provides 24 hours of training credits toward quality training and education for the attendee.

The first two days of training were held in the classroom and covered safety, operations, maintenance, and basic hydraulics. The third day was factory training, which provided hands-on experience where attendees train with the SBI Parts/Service and Quality Control departments, working directly with equipment to learn about its use, maintenance, and using it safely. Some of the topics discussed include hydraulics, poppet valves, power packs, schematic reading, troubleshooting, screw feeders, sludge pumps, preventative maintenance, and much more.

Push Floor Bin and Biosolids Pumps Help Plant Stabilize Operations


Written by Chuck Wanstrom

The City of High Point, NC, was previously pumping biosolids to an incinerator using hydraulically actuated piston pumps supplied by another manufacturer. These pumps were aging and the city couldn’t reliably obtain spare parts to support their operation. Additionally, the wastewater treatment plant occasionally struggled with operations as it didn’t have any buffering capacity for the dewatered biosolids ahead of the piston pumps. In an effort to solve the support issues with the existing equipment and stabilize operations, the city solicited bids from consulting engineering firms to update and improve their process.

The selected engineer began surveying biosolids handling systems available in the market and with input from their Client, settled on a push floor storage bin and piston pump arrangement as offered by Schwing Bioset. With over 30-years of experience in biosolids storage and conveyance, and numerous successful installations to its credit, Schwing Bioset was the logical choice to provide the design and equipment for this retrofit application.

A new push floor bunker with 60 yards of storage capacity was supplied to handle the centrifuge dewatered biosolids. Directly coupled to the bottom of the new push floor bunker are two Schwing Bioset model SD 350 screw feeders and KSP 17 piston pumps. The piston pumps have a dual-discharges that allows the biosolids flow to be split and fed into the incinerator at a total of four injection points for more efficient incinerator operations as well. If the incinerator goes down, biosolids can also discharge to a new truck loading facility.

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.   

Puyallup WWTP Sliding Frame1.jpg    Puyallup WWTP Sliding Frame2.jpg

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.
