  • Patent number: 11103830
    Abstract: Raw liquid is fed along a raw liquid and drain liquid mixing line to a liquid purification device. Drain liquid is fed along a recirculation line to be mixed with raw liquid. After a set period of time, the liquid purification process is interrupted to flush the liquid purification device by a liquid to remove contaminants built up on the inside surface of the liquid purification device. Downstream of the liquid purification device, the liquid is discharged at high speed into a drain. Prior to flushing, the purification process is interrupted at least once for a time sufficient to enable disruption of a polarized layer of contaminants. A mixture of raw liquid and drain liquid is used as the liquid medium for flushing such that less raw liquid is used for flushing and the service life of the water purification device increases.

  • Patent number: 11072547
    Abstract: The efficiency of water disinfection can be significantly increased by supplying the ozone in combination with oxygen to an inlet of a cavitation pump or a line atomizer. A compressor can be introduced at an inlet of the cavitation pump or the line atomizer, compressing the gas mixture at a pressure higher than the pressure within pump or the atomizer. The compressed gases are provided to the inlet of the atomizer or the pump, where the compressed gases mix with the water and enter the cavitation pump or the line atomizer (where most of the dissolution of the gases happens). The compressor allows to increase the amount of oxygen and ozone provided to the pump or the line atomizer, increasing their dissolved concentration. In addition to the disinfecting properties, the higher level of oxygen correlates to an improved taste of the water.

  • Patent number: 11072542
    Abstract: A water purification system includes a tank which stores permeate during periods of standby during which impurities can migrate across a filtration membrane, resulting in impure water on the downstream side of the membrane. During an initial portion of a water draw immediately following a period of standby, the impure water on the downstream side of the membrane is used as a motive fluid to force the permeate out of the tank for delivery to the faucet. Permeate is provided on a continuous bases directly from the membrane to the faucet after the tank is depleted of permeate. The system includes a control system and a plurality of valves to recycle the impure water used as a motive fluid to the membrane to produce permeate. At the conclusion of a water draw, the tank is filled with permeate and the system enters a period of standby until the next water draw.

  • Patent number: 11046603
    Abstract: Increased control and efficiency over the wastewater purification can be achieved through creating conditions that allow the operator to selectively prioritize the digestive function of microorganisms in the activated sludge. The gas-dispersion return sludge is created using pure oxygen or oxygen containing trace amounts of ozone as a reactive gas, which is blended with return sludge to create a mixture of gas and liquid, which is passed through an atomizer or a cavitation pump to instantly render the reactive gas to an ultra-fine bubble state. At least a portion of the ultra-fine bubbles dissolve within the gas-dispersion return sludge, activating the dormant microorganisms. Due to a complete or an almost complete absence of biodegradable material in the gas-dispersion return sludge, the microorganism prioritize their digestive function, and when exposed to biodegradable pollutants present in wastewater, digest the pollutants using biochemical pathways different from the ones used in nature.

  • Patent number: 11046606
    Abstract: The present invention is directed to a water container. The water container comprises a fluid path defined by a rigid fluid reservoir, a filter and a water outlet having an open position and a closed position; a fluid inlet, and a pump coupled to the fluid inlet. The pump comprises a non-return valve and a piston shaft through which a piston head may be moved, the piston head being coupled to a piston rod slidably moveable through an orifice at a first end of the piston shaft, wherein the orifice is sealed about the piston rod such that, in use, operation of the pump pumps fluid from a fluid source in communication with the fluid inlet, through the non-return valve and into the fluid reservoir so as to pressurise the fluid reservoir such that, when the water outlet is in the open position, a pressure differential induces a flow of water along the fluid path through the filter to the water outlet. The piston shaft is substantially surrounded by the filter.
