The improved water purification system includes a water purification unit having a tap water inflow port for receiving a tap water inflow from a water supply system to produce relatively purified water and a brine water outflow having impurities concentrated therein. An RO filter having an RO membrane separates relatively unfiltered water flow into purified water and the brine water outflow. A flush flow activation chamber fluidly coupled to the brine water outflow includes a plunger for substantially occluding brine water outflow through the brine outflow port when seated, and substantially permits brine water outflow to exit the purification unit through the brine outflow port when unseated. Accordingly, the activation chamber generates back pressure within the water purification system to flash flow tap water inflow into the purification unit and through the RO membrane when the plunger moves from being seated to unseated, thereby substantially refreshing said RO membrane.

The disclosure relates to a water treatment system which may include at least one reverse osmosis cartridge, at least one filtration cartridge, at least one pump and an enclosure.

An automated waste water treatment system includes a collection tank constructed to hold waste water, a first flow line connected to the collection tank to output the waste water from the collection tank, an electrocoagulation unit that receives the waste water and outputs the waste water as coagulated waste water to a flow line, a polymer dosage tank to provide a polymer dosage into the flow line where the polymer dosage mixes with the coagulated waste water to produce and output flocculated waste water. A clarifier connected to the flow line receives the flocculated waste water and produces sludge-free waste water and concentrated sludge, a series of filters to output filter-treated water, and an ultrafiltration system that receives filter-treated water and outputs ultrafiltration-treated water to a reverse osmosis system.

Per- and polyfluoroalkyl substances (PFAS) are destroyed by oxidation in supercritical conditions. PFAS in water is concentrated in a reverse osmosis step and salt from the resulting solution is removed in supercritical conditions prior to destruction of PFAS in supercritical conditions.

A filter module for a water dispensing device according to the present disclosure includes a filter housing which has an inflow port and a discharge port, and a plurality of filters which includes a filtration member provided in the filter housing to purify water flowing therein through the inflow port and to supply purified water to the discharge port, and filtering raw water flowing therein from the outside into purified water, and the filter module includes a pre-filter through which raw water passes firstly and in which a first carbon block having a hollow shape is built-in, a hollow fiber membrane (UF membrane) filter through which water passes through the pre-filter passes secondly, a second carbon block having a hollow shape through which water passing through the hollow fiber membrane filter passes thirdly, and an electrostatic adsorption member through which water passing through the second carbon block passes fourthly.

The present invention generally relates to a system and methods for the separation and removal of carbon dioxide from seawater. The system includes an extraction system that collects carbon dioxide from the seawater through a medium, and removes carbon dioxide from the medium; the extraction system comprising a reactor and a membrane. Alternatively, the extraction system includes a reactor, a membrane and a catalyst.

A biological reactor system treats concentrated contaminated water with a combination of upflow and downflow bioreactors that are downstream from a reverse osmosis or other concentrator. The system may have a fail safe configuration where flush water may be introduced to the reactors in the event of a power failure or when taking the reactors offline. Many reverse osmosis systems introduce antiscalant treatments upstream so that the reverse osmosis filters do not scale. However, such treatments result in superconcentrated conditions of the antiscalants in the contaminated water processed by the bioreactors. A flushing system may deconcentrate the bioreactors to prevent the antiscalants from precipitating and fouling the bioreactors.

A plant cell co-expressing at least one casein protein and at least one kinase. The at least one casein protein is phosphorylated by the at least one kinase in vivo. Casein micelles comprising phosphorylated κ-casein and at least one of αS1-casein, αS2-casein, and β-casein can be made in vivo and/or in vitro. The casein micelles can be used to make food products including milk and cheese.
