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.

Orlando Selects Schwing Bioset over Anaerobic Digestion for Class AA Biosolids

 

Authored by Tom Welch, Southeast Sales Manager for Schwing Bioset, Inc., and Vic Godlewski Jr., PE, Wastewater Division Manager, City of Orlando

May10, 2016

The City of Orlando has been working for several years to move away from Class B land application of Biosolids.  The City explored use of an experimental technology that would almost fully oxidize Biosolids leaving very little residuals for disposal.  While investigating this experimental technology, the City delayed renovations to the anaerobic digestion systems at their Conserv II Water Reclamation Facility (WRF).  Ultimately it was determined that the oxidation technology was not yet commercially viable, at which point they could no longer postpone biosolids treatment improvements.  Orlando engaged the services of a Consulting Engineer to evaluate the digesters and prepare project cost estimates from simple renovation to Class A TPAD with sidestream treatment and combined heat and power.  The estimated project costs were over $40 million and climbing.  Since Orlando believes that the market is going to deliver better options than anaerobic digestion in the future, they began to look for interim options that could be implemented relatively quickly at low capital cost investment; improve their Biosolids treatment, potentially eliminate the need for land application, and not substantially increase O&M costs.  That was a tall order!

The City 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 St. Petersburg as well as other locations 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.

Schwing Bioset offered a Design Build approach that was very appealing.  However, due to the City’s procurement constraints this path was not available. To speed up project delivery the Bioset process equipment was purchased directly by the City and installation was competitively bid.

As shown in the photos above, the Bioset equipment is currently being installed at the Conserv II facility and is scheduled for startup in the summer of 2016.  Schwing Bioset has a sister company, Biosolids Distribution Services (BDS), that manages Class AA Fertilizer Grade Biosolids in the state of Florida.  They have marketed in excess of one-million wet tons of Class AA fertilizer in the state of Florida over the last 10 years.  BDS will be managing the Biosolids produced at the Orlando Conserv II facility when the Bioset process becomes operational.

Schwing Bioset, Inc. Expands its Leadership Position as the Class A/AA Biosolids Solution Provider

 

Published on April 14, 2015 (Somerset, WI)

Schwing Bioset, Inc. has completed another successful Beneficial Reuse installation.  The City of Immokalee, Florida, chose Schwing Bioset to provide not only its Best in Class equipment, but design and build capabilities as well.

The heart of the system is the patented Bioset process and reactor that converts raw sludge into Class AA Biosolids, making it ready for easy land application.  Licensed as a fertilizer in the state of Florida, the Class AA product produced by the Bioset process is a highly marketable and sought after product.  Millions of tons have been produced and beneficially reused by the Bioset process. 

Taking advantage of some of the other high quality products Schwing Bioset offers, Immokalee integrated their Twin Piston Pump and Dewatering Screw Press into their design.

The Immokalee Water & Sewer District Executive Director, Eva Deyo, is very pleased with the system.  “The project came in under budget and went from concept to completion much quicker than other options.  As promised, the Schwing Bioset solution has proven to be easy to operate for our staff and very cost effective to operate, and the end product is exceptional,” said Deyo.  

Schwing Bioset Regional Sales Manager, Tom Welch, is thrilled with the results of the project.  “The City of Immokalee was tremendous to work with throughout the entire process.  Their vision and understanding of the value that the Schwing Bioset solution offered was evident throughout.  They realized after investigating numerous options that you don’t have to break the bank to get state-of-the-art technology,” said Welch.

“The experience of our Design, Engineering, and Project Management Teams has really shown during the execution of this fast track project.  The Schwing Bioset Team has executed on well over $150M in projects, with 2015 proving to be our biggest year ever,” said Tom Anderson, Owner and President of Schwing Bioset.

Schwing Bioset and Biosolids Distribution Services Open First Owned and Operated Regional Class AA/EQ Bioset Facility

Posted on August 28, 2013
The recently opened BDS and Schwing Bioset Regional Class AA/EQ Bioset facility receives outside sludge for treatment to Class AA/EQ on a pay-per-ton basis.

 

Ft. Meade, FL – Florida’s revised wastewater residuals regulations (F.A.C. 62-640) affect and limit the disposal options for municipalities producing biosolids. In response to the changing regulations, Schwing Bioset and BDS decided that the time was right to open a regional bioset facility that would accept outside biosolids and turn them into a Class AA/EQ material that has a wider array of beneficial reuse applications.

"Up till now, municipalities really only had one option when it came to biosolids. We saw this as great opportunity to innovate; an opportunity to break the mold and offer our clients with an alternative. In the most basic terms, our regional Class AA/EQ bioset facility allows wastewater treatment facilities to pay for biosolids processing without any capital outlay," stated Dan Anderson, General Manager of Biosolids Distribution Services.

The BDS regional Class AA/EQ bioset facility, located in Ft. Meade, Florida, accepts three primary types of material: cake sludge, septage and liquid sludge, and treats these materials using the patented Bioset process (liquid sludge and septage are dewatered before treated) which produces material that meets the highest quality standards set by the EPA, Class AA/EQ. Class AA/EQ material is exceptional quality and can be used as a fertilizer supplement or soil amendment.

"With significant advantages over other fertilizer products, the Class AA/EQ material created by the patented Bioset process is safe to be used as a fertilizer the next day," stated Anderson.

Florida’s revised regulations create challenges for any wastewater treatment facility whose biosolids do not meet Class A standards. Schwing Bioset and BDS are proud to offer these facilities with an alternative that is convenient and affordable and produces a sustainable end product for better reuse.

Schwing Bioset Secures Long-Term Trial with City of St. Petersburg

 

Posted on January 9, 2013

City of St. Petersburg upgrades biosolids treatment to Class AA/EQ using Schwing Bioset’s patented Bioset process. 

St. Petersburg, FL – Until recently, the city of St Petersburg, Florida’s Southwest Water Reclamation Facility relied solely on anaerobic digesters to stabilize their biosolids. However, the 20+ year old digesters had not only aged to a point of disrepair, but were beginning to cause odor complaints from the neighbors. Hence, the city felt the pressure to take corrective action quickly.

Not only would rehabilitating the existing digesters entail a sizeable expense, but in the end, the digesters would still only be producing a Class B product that needed to be hauled off to land sites. In the past this was not an issue, but the new F.A.C. 62-640 rule in Florida is going to make Class B biosolids harder to reuse in a beneficial manner.

Schwing Bioset brought in their mobile Bioset System to the St Petersburg facility in June of 2011 for a 5-day trial. Demonstrating their ability to use a natural process that eliminates pathogens by elevating pH and temperature, they proved their ability to create a Class AA/EQ product from the facility’s biosolids that would meet the 62-640 rule in Florida.

After successfully providing Class AA within 24 hours of setting up the equipment for the trial, the city engaged in an active discussion with Schwing Bioset to extend their trial to a full year. In this time, Schwing Bioset would be contracted to install all equipment, make sure operators were trained properly, and modify the city’s existing operation for a year-long period. Presently the equipment is operating successfully, the digesters are off line, the odor complaints have been eliminated, and the plant is producing Class AA/EQ biosolids that are being beneficially reused locally.
