摘要： The invention relates to the treatment of water, including for example treatment in connection with hydrocarbon production operations. Silica in water produces undesirable scaling in processing equipment, which causes excess energy usage and maintenance problems. Electrocoagulation (EC) at relatively high water temperature followed by ultra-filtration (UF filtration) may be combined with forward osmosis (FO) to treat water. Water to be treated may be produced water that has been pumped from a subterranean reservoir. The treated water may be employed to generate steam. The treatment units (e.g., EC, forward osmosis, UF filtration, etc) can be configured into one system as an on-site installation or a mobile unit for on-site or off-site water treatment.

摘要： The invention relates to the treatment of water, including for example treatment in connection with hydrocarbon production operations. Silica in water produces undesirable scaling in processing equipment, which causes excess energy usage and maintenance problems. Electrocoagulation (EC) at relatively high water temperature, followed by any of membrane distillation or forward osmosis (FO), may be combined with a subsequent process of ceramic ultra-filtration (UF filtration) employed to treat water. Water to be treated may be produced water that has been pumped from a subterranean reservoir. The treated water may be employed to generate steam. The treatment units (e.g., EC, forward osmosis, UF filtration, etc) can be configured into one system as an on-site installation or a mobile unit for on-site or off-site water treatment.

摘要： The invention relates to a system for use in the treatment of produced water, e.g., water treatment in connection with hydrocarbon production operations. Silica in produced water produces undesirable scaling in processing equipment, which causes excess energy usage and maintenance problems. Electrocoagulation (EC) at relatively high water temperature, followed by any of membrane distillation (MD) or forward osmosis (FO), may be combined with a process of ceramic ultra-filtration (UF filtration) to treat water. Water to be treated may be produced water that has been pumped from a subterranean reservoir. The treated water may be employed to generate steam. The system comprises a plurality of units (e.g., EC, forward osmosis, membrane distillation unit, UF filtration, etc) which can be configured as an on-site installation or a mobile unit for on-site or off-site water treatment.

摘要： A process for treating acid mine drainage containing heavy and base metals and soluble contaminants is provided. In one embodiment, at least a metal cation is added to the acid mine drainage at a pre-select pH to form insoluble heavy and base metal complexes. After the removal of the heavy and base metal complexes, the pH is raised to the alkaline range. Following removal of base metal hydroxides and gypsum, membrane filtration is employed to generate a treated membrane permeate having a reduced concentration of heavy and base metals and soluble contaminants, and a membrane reject stream containing a concentrated brine. The concentrated brine is further treated with additional lime and at least an aluminum salt to remove remaining soluble contaminants, thus producing a treated water stream with reduced levels of contaminants. Carbonation with CO2 is employed at the end of the process to neutralize flows and further precipitate residual aluminum and calcium salts.

摘要： An energy-efficient process for dewatering an aqueous organic solution includes using freely available solar energy to concentrate a draw solution within a reservoir. The draw solution is used in conjunction with a membrane to remove water from the organic solution in a forward osmosis process. The draw solution is diluted by the osmosis process, and returned to the reservoir to be re-concentrated and reused in the osmosis process.

摘要： A method and system using hybrid forward osmosis and nanofiltration is disclosed for treating produced water containing contaminant species. The system comprises a forward osmosis cell and a downstream nanofiltration cell. A draw solution fluid cycles between the forward osmosis cell and the nanofiltration cell. The draw solution contains polyvalent osmotic agents producing polyvalent ions in the draw solution. The passage of monovalent ions through the nanofiltration membrane is hindered due to the presence of conjugate polyvalent ions.
