Small industrial plant
Our full-scale commercial pilot: from nutrient removal prototype to validated IES technology at ~15 m³/d capacity.
Case Study Overview
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 reals waste-treatment setting while monitoring the nutrient recovery and biogas production.
- To verify the technology’s profitability.
