General Environmental Science, Inc. (GES) is a world wide developer and manufacturer of bacterial based products for wastewater treatment. GES was founded in 1974 by Mr. Barton Gilbert in response to the growing concern of the problems of municipal wastewater treatment.

GES initially specialized in bacterial products for municipal wastewater treatment. Over time GES developed products and technologies to improve all types of wastewater treatment, including municipal wastewater treatment, industrial wastewater treatment, aquaculture wastewater treatment and lake and pond remediation.

Municipal wastewater treatment technologies include sludge reduction, effluent improvement and nitrification. Other wastewater
treatment technologies include grease reduction, septic system treatment and algae reduction. Our cutting edge technologies are used in wastewater treatment applications around the world. In fact GES is the holder of four patents related to bioaugmentation. GES markets its products in China through our joint venture partner Ascenda Environmental Science Corporation (AES) located in Ningbo.
