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 13):
The method of  claim 3  further comprising directing the produced water to a gas flotation unit and removing total organic carbon in the produced water prior to chemically softening the produced water;\n and wherein removing total organic carbon in the produced water includes adding an acid to the produced water such that carbonates and bicarbonates in the produced water are converted into CO 2 ; \n adding ferric chloride (FeCl 3 ) to the produced water to form Fe(OH) 3  such that carbon in the produced water is adsorbed onto the Fe(OH) 3 ; \n adding a polymer to the produced water; and \n directing gas upwardly through the produced water such that suspended solids in the produced water move upwardly towards the surface of the produced water, removing the suspended solids from the produced water.
