A.H. Lundberg is partnering with electrocoagulation vendors to solve the challenges faced by the oil & gas industry in treating wastewater.
Electrocoagulation can efficiently remove contaminants such as suspended oil and grease, silica, calcium, magnesium, heavy metals and suspended solids from aqueous waste streams. A primary advantage of the process is high removal efficiency (90%-99%) of the contaminants with no chemical addition, minimum waste produced, low power operating cost (4-7 kWh/1000 gals treated) and minimal manpower requirements.
Feed from the electrocoagulation process is transferred to the evaporation process. A simple block diagram shows how the Zero Liquid Discharge process can be designed.
