Schwing Bioset – Phosphorous Recovery Technology

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.

Goals of Nutrient Management by Schwing Bioset:

Be a Steward of Global Sustainability

  • Offset the dwindling supplies of worldwide phosphate reserves
  • Help prevent eutrophication of sensitive waterways
  • Convert your wastewater plant to a resource recovery center

    Solve Plant Operation Problems

  • Avoid scaling and clogging of pipes, pumps, and in dewatering equipment
  • Reduce accumulations in tanks that cause shutdowns for removal
  • Help your plant meet its discharge limits

    Benefits of Struvite Recovery

  • Improve dewaterability of biosolids by re-balancing mono and divalent cation ratios
  • Create a valuable product from your waste stream
  • Market the harvested product under trade name Bio-Stru®
  • Harvested struvite can be marketed independently by the municipality or through Schwing Bioset's marketing channels

    Technology Features

  • Process can be applied on either digestate, centrate, or a combination of both
  • Accommodates variable dewatering schedules as all configurations operate continuously or intermittently in batch mode
  • pH adjustment and struvite precipitation are accomplished in separate vessels for stable and precise process control, which eliminates the need for addition of caustics
  • Fully automated process controls
  • Low operating and maintenance expenses

    Solution Strengths, Weaknesses and Critical Indicators

    Struvite, also known as Magnesium Ammonium Phosphate (MAP) is a slow-release phosphorus-rich product with the following attributes: 

    • Produced by treating dairy wastewater with chemicals 
    • Proven chemical process for municipal wastewater treatment 
    • Advanced phosphorus recovery systems for treating dairy manure typically cost more than those for other animal manures 
    • All advanced phosphorus recovery systems increase the cost of treating dairy manure over that of conventional treatment 
    • Effective in removing a high percentage of phosphorus when used with proper chemical treatment
    • Value of technology will be based on the marketability of the finished product 
    • Proven technology for nitrogen recovery, phosphorous recovery, and pathogen reduction

    NuReSys 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 and NuReSys to further refine the cost and performance information as information comes in with commercial dairy installations.
