This device adopts the gas field water pre-treatment and re-injection process of "separation of oil + multi-level natural sedimentation + flocculation
sedimentation + chemical dosing disinfection + deep injection", which uses physical and chemical methods to efficiently remove various pollutants in
produced water. It can effectively prevent cracks and holes from being blocked, reduce the floor area occupied by water treatment facilities, and lower
operating costs.
