Swt’s feedstock conditioner increases methane production by 10-30%

Spiral Water’s  Model HS-RNG Feedstock Conditioner, is a wastewater treatment system designed for use in biogas production. This system, which integrates the company’s proven technology with specialized process flow conditioning, is in use at several dairy farms around the U.S. As part of a multi-stage separation approach, it has been shown to condition feedstocks for higher yield gas production and lower OpEx.

Placed before an anaerobic digester, the Spiral Water system conditions and optimizes volatile Total Suspended Solids (TSS) and Volatile Suspended Solids (VSS) by breaking down deformable solids and making for a more nutrient-rich feedstock liquor that then goes through the specifically selected micron screens to the digester.

Depending on the feedstock, with this system the anaerobic digesters are expected to create 10-30 percent more methane in the same footprint in a shorter digestion cycle time.  In addition, because the filters clean mechanically, they also remove non-digestibles from the wastewater stream. By keeping digester tanks cleaner, the filters also help to reduce OpEx.

Spiral Water systems have proven to be a key component in small and midsized anerobic digestion systems. By effectively removing inorganic non-digestible solids and homogenizing digestible solids, we increase gas production as well as reduce operating costs wasted on removing non-digestible solids from the gas digester. The result is a cleaner, more productive anerobic digester system

Other benefits include less retention time; no chemicals; lower energy requirements; less maintenance and labor costs than with traditional systems; less CapEx and OpEx than using centrifuges; and the potential for a smaller digester footprint in a newly constructed system.

Join Us at Biogas Americas!

If you are involved or interested in renewable natural gas (RNG) production, the BIOGAS AMERICAS conference and trade show, May 13 – 16 in Savannah, Georgia, is a “must attend” event. Come visit us at Booth 844 in the exhibition, which runs from Wednesday May 15 – Thursday May 16.

Spiral Water offers a portfolio of solutions engineered for biogas production, and we are proud that our filtration technology is being used in more and more RNG installations around the country.

Biogas production is a vitally important and burgeoning industry. Here are just a few reasons why:

  • According to the American Biogas Council, more than 2,300 sites are producing biogas in 50 states across the U.S.
  • The U.S. has the potential to build more than 15,000 new biogas systems.
  • Directly replacing fossil fuels with biogas offers many benefits ranging from the environmental to financial. Biogas helps reduce GHG emissions, recycle organic waste into renewable energy, and create new sources of revenue.

We look forward to exhibiting at the show – the largest gathering of the U.S. biogas industry this year and home to the American Biogas Council’s annual conference. We hope that you can join us at this important event!
