An apparatus for filtering and mineralizing a fluid. The apparatus includes an amount of contaminated fluid located in a reservoir and a cartridge that is located downstream from the reservoir and in fluid communication with it. A filter is in fluid communication with the reservoir and the cartridge. The contaminated fluid is pumped along a pathway from the reservoir to the cartridge so that the contaminated fluid moves through the filter to generate filtered fluid in the cartridge. A pre-determined amount of an additive is associated with the cartridge for adding to the filtered fluid to generate a final fluid with the amount of the additive material.

The present disclosure relates to an artificial, extracorporeal system for supporting the function of the liver of a patient suffering from liver failure, which is characterized in that it comprises a first high-flux or high cut-off hollow fiber membrane dialyzer which is perfused on the lumen side with the patient's blood and wherein a buffered aqueous solution comprising human serum albumin is passed in a continuous flow through the filtrate space of said first dialyzer, a second hollow fiber membrane dialyzer which removes water-soluble substances from the dialysate of said first dialyzer, and a third, integrated hollow fiber membrane dialyzer which is perfused with the retentate of second hemodialyzer and which allows the passage of certain amounts of albumin over the membrane wall into the filtrate space which is populated with adsorbent material. The system can be used for the treatment of acute liver failure and acute-on-chronic liver failure.

An apparatus for the treatment of wastewater having: a primary treatment module with at least one solids separation filter; a secondary treatment module with at least one microflotation unit and at least one oxidation treatment unit placed downstream of the at least one microflotation unit, the at least one oxidation treatment unit has an advanced oxidation process module for performing chemical processes, the advanced oxidation process module performing an ozone and hypochlorite treatment; a tertiary treatment module including at least one membrane filtration unit; the apparatus provided with sequentially flowing wastewater from the primary treatment module, through the secondary treatment module, and to the tertiary treatment module. A method for wastewater treatment in an apparatus having as sequentially treating wastewater through the primary treatment module, the secondary treatment module, and the tertiary treatment module.

A high salinity water purification system and process, including a forward osmosis system and a reverse osmosis or nanofiltration system. A concentrated brine of a zinc or iron complex combined with a salt or acid draws pure water across the FO membrane from the influent water. The diluted brine is pumped through a vessel holding an anionic adsorption media to remove the zinc or iron complex and the resultant brine is passed through the RO or nanofiltration system to obtain purified water and a concentrated brine stream. The adsorption media is regenerated by a rinse cycle using fresh water or water from the RO system, removing the zinc or iron complex adhered to the media. The resultant brine is stored and mixed with the output of the RO system. Charged membrane can be used as a standalone membrane in FO process or in combination with resin or resin embedded membrane.

A process for purifying a urea-containing aqueous stream, such as the aqueous stream from the recovery section of a urea plant, comprising a step of removing biuret from the urea-containing stream by reverse osmosis in one or more reverse osmosis stages.

The present disclosure is in the field of ‘pharmacognosy’ and ‘chemistry of natural products’. The present disclosure generally relates to a process of isolation and purification of Biochemical Constituents from algae. The present disclosure particularly relates to a process of isolation and purification of Biochemical Constituents from a biomass of cyanobacteria. The present disclosure provides a process for isolating and extracting phycocyanins, chlorophylls, proteins and polysaccharides from the spirulina biomass.

A filter unit includes an inlet for receiving unfiltered water. A first fluid path directs water through a membrane and a filter element to a first outlet. Additionally, a second fluid path directs water across the membrane and to a second outlet.

A control system has a water purification module and a control module. The water purification module has a preliminary filter and a reverse osmosis filter. The control module regularly controls the purification and the drainage of the water purification module, and solves the problem that the TDS value of the water on both sides of the reverse osmosis membrane is too high after the water purifier is on standby for a period of time. The control system regularly drains high concentration water on both sides of the reverse osmosis membrane to improve water purification efficiency.
