Abstract:
A method or process for treating wastewater containing high organics, silica, boron, hardness, and suspended and dissolved solids. The method includes degasifying the wastewater for the removal of dissolved gases and thereafter chemically softening the wastewater. After the chemical softening step, the wastewater is directed through a media filter or membrane which removes additional solids and precipitants. Thereafter the wastewater is directed through a sodium ion exchange that further softens the wastewater. The effluent from the ion exchange is directed through a cartridge filter and the effluent from the cartridge filter is directed through one or more reverse osmosis units. At a selected phase of the process, prior to the wastewater reaching the reverse osmosis unit or units, the pH of the wastewater is raised and maintained such that the pH of the wastewater reaching a reverse osmosis unit is at a pH greater than 10.5.

Claim (Index 3):
A method of recovering oil or gas from an oil or gas well and treating resulting produced water, comprising:\n a. recovering an oil/water or gas/water mixture from the oil or gas well; b. separating oil from the oil/water mixture or separating gas from the gas/water mixture to produce an oil or gas product and the produced water, and wherein the produced water includes organics, silica, hardness, dissolved solids and suspended solids; c. reducing hardness in the produced water by chemically softening the produced water in a chemical softening unit which results in the formation of hardness precipitants; d. raising the pH of the produced water to 10.5 and above; e. directing the produced water having said pH of 10.5 and above to a mixing tank forming a part of the chemical softening unit and mixing the produced water in said mixing tank and causing crystallization of the precipitants within the produced water; f. after crystallization, removing free oil and crystals from the produced water by directing the produced water through a membrane filter and producing a membrane effluent and a membrane reject stream containing free oil and the crystals; g. recirculating at least a portion of the membrane reject stream to the chemical softening unit and causing the crystals in reject stream to grow larger; h. directing the membrane effluent to an ion exchange unit and further softening the membrane effluent by removing residual calcium and magnesium hardness therefrom and producing an ion exchange effluent and a waste stream; i. after further softening the membrane effluent, directing the ion exchange effluent to at least one reverse osmosis unit and removing dissolved solids from the ion exchange effluent and producing a reject stream and a permeate stream which contain organics; j. mixing hydrogen peroxide (H 2 O 2 ) with the permeate stream; k. after mixing hydrogen peroxide with the permeate stream, subjecting the permeate stream to ultraviolet irradiation and converting the hydrogen peroxide in the permeate stream into hydroxyl radicals (HO.); l. employing the hydroxyl radicals to oxidize the organic content contained in the permeate stream.
