Xinjiang Tarim Oilfield

Problem

The mud filtrate has high chroma, strong acidity with the pH value ranging from 2-3, and high solid content. It appears to be typical colloidal state, which has complex components, high salinity and SS concentration, and therefore it is very difficult to deal with. If discharged to the environment, it can cause a great impact on the environment, resulting long-term serious hazards and pollution to groundwater and soil environment. No vegetation can live on the contaminated soil, and the ecological environment is difficult to restore for a long time.

Pollutant

Waste drilling mud filtrate

Solution

Our Company adopts the combined process of "efficient flocculant" and "high speed centrifuge" to process the pollutant, and the treated pollutant can reach the standard to flow into the combination station.

Achievement

Treatment capacity: 10 m³/h
Standard of output water: Oil content < 200 mg/l SS < 200 mg/l Chroma < 50 times
