Case Study and Pilot Project Descriptions and Results

Prototype Case Study

SGTech developed a prototype on an Israeli dairy farm for proof of concept in 2016.

SGTech successfully tested its technology at this facility by treating ~2 m3/d (~530 gal/d) of influent waste containing 1-2% dry matter.

Prototype Case Study Results:

TSS 12,000 340 97%
COD 15,000 1,400 91%
TKN 800 150 81%
TP 180 38 79%

Commercial Pilot Case Study

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: 

  • Test the technology’s robustness in a real waste treatment setting while monitoring both the nutrient recovery and biogas production.
  • Verify the economical profitability of the technology.

The results are shown in the table below.

Parameter Units Influent Effluent Percent Removal
COD mg/L 40,000 2,000 +/- 400 95%
TSS mg/L 25,000 700 +/- 30 97%
TKN mg/L 1200 150 +/- 50 88%
TP mg/L 230 55 +/- 13 76%
Ammonia mg/L 600 10 +/- 5 98%
pH - 6 ~7.3 +/- 0.4 -

Research and Development Capabilities

  • In-house
    SGTech operates an in-house laboratory with a lab-scale reactor in addition to its pilot-scale facility. This enables SGTech to conduct extensive R&D to further validate and innovate the IES process.
  • Universities
    SGTech is partnering with multiple universities in Israel to conduct additional research and development experimentation. SGTech remains the sole owner of all IP generated through these endeavors.
  • Always Innovating
    SGTech is committed to the continued innovation of its product offering and is aiming to apply for additional patents on the IES process in the coming year.
