Additionally, a rainwater collection system for delivery of said rainwater to a domestic system for use thereof. The system comprises first flush diverter, screening stage, filtering stages, buffering stage, settling/resting stage, disinfection and/or purification stage.

A facility for the subsea disposal of the water produced during deepwater hydrocarbon production, includes a subsea oil/water separation station fed with fluids coming directly from at least one hydrocarbon production well, operating at a pressure independent of and lower than the ambient pressure, and comprising an oil outlet for connecting to a production unit and a water outlet, a flat gravity oil/water separation tank resting on the seabed, continuously fed with water leaving the oil/water separation station, operating at a pressure substantially equal to the ambient pressure, and comprising an oil outlet for connecting to the production unit and a water outlet, and a subsea high-pressure pump connected to the water outlet of the oil/water separation station and to a water inlet of the tank to raise the pressure of the water leaving the oil/water separation station to the ambient pressure before it is admitted into the tank.

A solid-liquid separator including a hollow structure. The hollow structure may include a separator portion having a solid-liquid-mixture inlet and a curved-funnel-shaped inner separator surface. The hollow structure may further include a collector portion having a frustoconically-shaped inner liquid guide surface. The separator portion and the collector portion may be disposed such that a spout of the curved-funnel-shaped inner separator surface and a narrower end of the frustoconically-shaped inner liquid guide surface may be directed towards each other.

The present disclosure provides apparatus, systems, and methods for improving slop water treatment efficiency. The method generally includes separating contaminated fluid into a clean fluid layer and one or more contaminant layers floating on a surface of the clean fluid layer in a vessel; reporting to a control unit, a location, sensed by level sensor(s), of an interface between the clean fluid layer and the contaminant layer(s); reporting to the control unit, a height, sensed by a first position sensor, of a skimmer relative to the vessel; adjusting, using the control unit and based on the reported location of the interface and/or the reported height of the skimmer, the height of the skimmer so that one or more components of the skimmer are positioned proximate the sensed location of the interface; and skimming, using the skimmer, the contaminant layer(s) off of the clean fluid layer proximate the sensed interface.

A separator fluidly connected to a wellbore includes: a vessel defining an interior chamber; an inlet for delivering fluid produced from a wellbore into the vessel at a first pressure; an outlet through which gas is directed out of the vessel at a pressure substantially equal to the first pressure; at least one liquid/oil level sensor capable of detecting the level of liquid within the interior chamber of the vessel and the level of oil within the interior chamber; two electronically controlled valves in fluid communication with the vessel; and a controller connected to the at least one liquid/oil level sensor and the electronically controlled valves and programmed to, in response to a level of the liquid and a level of oil in the interior chamber of the vessel: open, close, or modulate the electronically controlled valves to regulate the combined flow liquid and oil out of the vessel.

A method and apparatus is provided for water filtration of a milk of lime solution that contains water, impurities, and grit particles, in which the milk of lime solution enters a vessel, and wherein turbulence is created in the vessel, by which larger grit particles settle out of the milk of lime solution, to form a bed of grit particles in the lower end of the vessel, such that grit particles and impurities are filtered from the lime-treated water that comprises a milk of lime solution, with water then being drawn off, that may be discharged out one or more dosing locations and/or recycled back for further filtration, as may be desired.

A floating liquid intake for a liquid suction removal system, the liquid intake comprising housing defining an internal cavity. The housing has a hollow and buoyant annular body, an upper cover and a lower cover. The internal cavity is formed between the upper and lower covers. A substantially annular inlet is formed in the annular body for ingress of liquid into the cavity. The annular body has a buoyancy sufficient for the liquid intake to float in a liquid with the annular inlet submerged below the surface of the liquid in which the liquid intake is floating. A pipe extends into the cavity and the pipe includes an inlet that in use is open below the surface of the liquid within the cavity. The pipe extends outside of the cavity for connection to a liquid suction removal system.

A machine and methods using electro-chemical treatments, sedimentation processes and dissolved air flotation technologies for clarification of several kind of wastewater produced in industries, sewages, ponds, lakes, canals etc. The machine comprises of, feeding lines with multiple feeding point, a tank and further a collection tank. The wastewater is passed into the feeding line which may comprises of several feeding points for coagulants, flocculants, and other chemicals dosing into the flow of wastewater and may also comprises of a static mixer for mixing the coagulants, flocculants, and other chemicals with wastewater to agglomerate any solid particles and to accelerate separation of the solid particles in the tank. Once the solid are formed, they can go up or down, therefore to remove the suspended solids the outlet are rearranged depending on the suspended solids. Further, the machine is used for treatment of wastewater utilising multi pass concept to produce clean water.

A polishing agent regenerating method in which a component of a polished material is removed from polishing agent slurry and a polishing agent is collected and regenerated is shown. The method includes at least, polishing, polishing agent slurry supplying, polishing agent slurry collecting, and sedimenting/separating/concentrating, performed in the above order. In the polishing agent slurry collecting or the sedimenting/separating/concentrating, a K.sub.2O density in the polishing agent slurry after dilution by water is performed is to be within a range of 0.002-0.2 mass %.
