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 5):
The method of  claim 3  wherein the produced water includes free oil and wherein the method includes, prior to removing hardness, directing the produced water to a treatment unit disposed upstream of the chemical softening unit for removing free oil and reducing turbidity and the concentration of organics in the produced water and including:\n mixing an acid and a coagulant with the produced water; \n after mixing the acid and the coagulant with the produced water, directing the produced water to a gas flotation chamber; \n mixing a polymer with the produced water in the gas flotation chamber; \n directing a gas through the produced water in the flotation chamber wherein gas bubbles associated with the gas to facilitate the removal of the free oil and insoluble organic particulates in the produced water as the gas bubbles rise to the top of the produced water in the gas flotation chamber and the method includes skimming the gas bubbles from the produced water; and \n directing the produced water from the gas flotation chamber and directing at least a portion of the produced water to the chemical softening unit and recycling another portion of the produced water from the gas flotation chamber back to the gas flotation chamber.
