Small industrial plant

After its successful nutrient removal prototype, SGTECH developed a commercial pilot scale-up (~15 m3/d, ~4,000 gal/d) in 2017 to further validate the IES technology.

The pilot was designed to treat the entire organic waste stream of a dairy farm (raw manure + milking parlor slurry).

The aim of this case study was dual: :

• To test the technology’s robustness in a real waste-treatment setting while monitoring the nutrient recovery and biogas production.
• To verify the technology’s profitability.
