Project Description

The wastewater plant was designed and operated for CNPC Petrochemical Group in Jilin, China. The main product of the petrochemical plant is Acrylonitrile Butadiene Styrene (ABS) material, which is extremely difficult to be removed from wastewater. Besides that, the raw wastewater contains high concentration of COD, SS and ammonia.

Two Implementation Phases

Phase 1 (2010): 1,000 m³/d (264,000 GPD) pilot study phase
Phase 2 (2012): 6,000 m³/d (1,585,000 GPD) full scale phase
