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.

USEPA PEC Committee Grants PFRP Approval to the Bioset System

The USEPA PEC Committee Grants Nationwide PFRP Approval to Schwing Bioset and Its Class 'A' Biosolids Process known as the Bioset System

After extensive testing and research, Schwing Bioset is proud to announce that the USEPA has given nationwide approval to the Bioset Process to reduce its operating temperatures from 70°C (158°F) to 55°C (131°F) as a Process to Further Reduce Pathogens (PFRP). Operating at 55°C (131°F) results in a greater than 20% reduction in operating costs for owners of the Bioset process.

After extensive testing and research, Schwing Bioset is proud to announce that the USEPA has given nationwide approval to the Bioset Process to reduce its operating temperatures from 70°C (158°F) to 55°C (131°F) as a Process to Further Reduce Pathogens (PFRP). Operating at 55°C (131°F) results in a greater than 20% reduction in operating costs for owners of the Bioset process. Prior to receiving nationwide approval, site-specific approval at one site in Texas had been granted.

The Schwing Bioset Process is a technology that continuously converts municipal biosolids into a Class A/EQ saleable product in full compliance with 40 CFR Part 503 Rule. The process mixes dewatered biosolids with calcium oxide (quicklime) and sulfamic acid (solid granular acid) and continuously pumps it into a plug flow reactor. The Schwing Bioset Process currently meets Class ‘A’ standards via pasteurization at 70°C for 30 minutes, and vector attraction reduction by maintaining an elevated pH.

At the elevated pH levels, ammonium contained within the biosolids evolves as ammonia, and the ammonia is maintained in solution with the biosolids in the pressurized plug flow reactor. Miscible contact of the ammonia with the biosolids enhances pathogen destruction to Class A/EQ standards at lower temperatures. Mixing is accomplished with Schwing Bioset’s twin-screw feeder and the blended material is pumped into the plug flow reactor with Schwing Bioset’s twin- cylinder positive displacement piston pump.

The combination of high temperature, high pH and the biocidal effects of ammonia ensure that the biosolids are pathogen free in accordance with Class A/EQ requirements. The end product is characterized as a lime enhanced soil amendment and is a valuable product for numerous land application markets. Because the Calcium in the Class A/EQ end product is readily available, soil pH adjustment occurs in less than half the time of what typical agricultural lime products require. An additional benefit of the end product is that the high percentage of organic content (35-55%) returns organic material to depleted soils.
