A method of treating oil and gas produced water may include: receiving produced water from one or more wells; separating an aqueous portion of the produced water from oil and solids included in the produced water in order to provide recovered water; performing anaerobic bio-digestion of organic matter included in the produced water using a biomass mixture of anaerobic bacteria obtained from a plurality of wells; aerating the recovered water in order to promote metal precipitation; and performing aerobic bio-digestion of organic matter present in the recovered water. Some embodiments may also include one or more of anoxic equalization, filtration, pasteurization, reverse osmosis, and biocide treatment of the recovered water. The recovered water may be used for oil and gas well fracking and/or land and stream application. Other methods of treating oil and gas produced water are also described.

Methods and apparatus for treatment and purification of oil and gas produced water

Methods for treatment and purification of oil and gas produced water

Systems and methods of collecting, treating, and recycling oilfield drilling fluids, used oilfield water, and other wastewater are disclosed. A separator may be used to separate a fluid mixture into one or more liquids and one or more solids. Water, oil, or other liquids may be recovered from the separator and further processed by aeration, filtration, and/or pasteurization, making them suitable for reuse in oilfield drilling and/or fracking operations or other industrial applications, such as truck or equipment washing. Sludge from the separator may be dried to produce dried solids, which may also be used for various applications, such as road base.
