Schwing Bioset – Fluid Bed Processing

Recovering Nature's Essentials

About the Company:

For more than 30 years, Schwing Bioset Inc. has been helping wastewater treatment plants, mines and power generation customers by engineering material handling solutions. Schwing Bioset’s custom-engineered solutions can be found in hundreds of wastewater treatments plants in North America, as well as mines and tunnels around the world.


Schwing Bioset, Inc. was founded in 2006 by separating the Material Handling Division of Schwing America into its own company. This company was created to pioneer and develop high performance, remarkable material handling solutions.


In April 2006, Schwing Bioset, Inc. (SBI) moved to a new manufacturing facility in Somerset, WI. Somerset is located in the scenic Saint Croix River Valley along the Minnesota and Wisconsin border and is only one hour away from the Minneapolis/St. Paul International airport. This dynamic region is home to some of the finest summer and winter activities of the region and is an ideal setting for the continued growth of SBI.


The 20,000 square foot factory is home to the engineering and manufacturing of the high quality products Schwing Bioset offers. Schwing’s Project Management and Fluid Bed Drying teams remain located in their respective locations of Danbury, CT and Houston, TX.


Schwing Bioset is now in partnership with NuReSys to bring its Struvite Recovery Technology to North America. The NuReSys approach is customer driven and primarily problem solving, related to phosphate issues. The flexibility of the NuReSys process allows to select a number of variants and/or combination to resolve the customer’s specific and/or critical phosphate related issues.

    Solution Strengths, Weaknesses and Critical Indicators

    Active Drying Technologies:

    • Produce a marketable product, dry manure solids, and reduce transportation costs
    • Require energy to reduce water content and dry manure solids, purchased energy cost are an issue
    • Require operator attention in excess of other systems due to the risk of combustion
    • Other compounds are released with the water (i.e. ammonia, hydrogen sulfide), and require additional treatment
    • Potential loss of ammonia nitrogen due to volatilization
    • Proven technology for storage reduction, odor control, GHG reduction and pathogen reduction

    Newtrient Comments/Opinions:

    This Technology has not been evaluated using Newtrient's 9-point scoring process because, although their process appears to be suited for use on dairy manure, Newtrient is not aware of any current North American based dairy projects.  Newtrient will continue to work with Schwing Bioset to further refine the cost and performance information as information comes in with commercial dairy installations.
