A device that serves to increase the pressure on the outlets of water intakes in houses or gardens. This system to increase the water pressure is called salt-cellar-like device for increasing pressure. The salt-cellar-like device for increasing pressure has 6 external walls that give its body a hexagonal shape. These external walls allow the device to be held firmly by some tool that rotates the device, so that it is correctly inserted and attached to some water intake. The salt-cellar-like device for increasing pressure has a head that has a circular concavity on its upper part, as well as on the surface of this circular concavity there is an arrangement of conduits from which the water leaves the device to a higher pressure.

A valve for a water system including a water supply conduit, the valve having a valve housing that defines a valve inlet and valve outlet. The valve inlet is connected to the water conduit and at least one piston is disposed within the valve housing and is configured to direct flow within the valve. A motor associated with the valve housing is operably attached to the piston and is further configured for driving the piston between a service position, a bypass position, and a shutoff position. The valve further includes at least one sensor associated with the valve inlet or valve outlet for monitoring a water condition. A control system receives data from the at least one sensor and is configured for actuating the motor between the service position, the bypass position, and the shutoff position in response to the data.

A combined vessel comprises a stripping section for removing acid gases from a sour water stream and a direct contact heat exchanger section for heating a graywater stream in order to improve heat and mass transfer in the treatment and recycle of water streams for a gasification process.

The invention relates to a method for activation of concrete mixing water. The method includes preliminary action on the mixing water in continuous flow by pulsed high-voltage electrohydraulic discharges with supply DC voltage from 500 V to 5000 at a pulse frequency from 2 Hz to 10,000 Hz and a current from 0.1 A to 10 A on electrodes of copper and/or iron and/or titanium. Then the water is treated in a mechanical and/or ultrasonic cavitator in the developed cavitation mode and at a water pressure from 0.8 atm to 6 atm without addition of plasticizers and/or surface-active agents.

The present invention is a two-part irrigation system that utilizes both groundwater and rainwater. The first system extracts water from groundwater layers by using extraction pipes filled with nanomilled sand that constantly moves water upwards through capillary action. The second is a rainwater collection and capillary irrigation system. The groundwater irrigation system consists of an external groundwater transport pipe filled with nanomilled sand. This encapsulates an empty internal transport pipe that delivers percolated water. The rainwater irrigation system consists of a collection, storage, filtration, and capillary irrigation system. Rainwater is collected by trays and a water tank, where the water is filtered through a hollow fiber membrane filter. This clean water is used as potable drinking water or for irrigation. The water volume required for irrigation is calculated based on moisture data collected by moisture detection devices. Both systems are solar powered, and are controlled and programmed by the user.

A system for transferring marine life within an aquaculture facility including a plurality of segregated storage facilities each containing water for marine life, maintained within a predetermined temperature range and supported at independent ground levels. The storage facilities are successively disposed and structured to contain marine life at different stages of growth. A transfer assembly includes a path of fluid flow interconnecting successive ones of said plurality of storage facilities in fluid communication with one another, wherein at least a majority of a length of said path of fluid flow is disposed beneath the independent ground levels at a predetermined depth, which is sufficient to facilitate maintenance of the path of fluid flow within the predetermined temperature range, via geothermal cooling. The transfer assembly may also connect a holding facility, which may be dimensioned and structured to transfer mature marine life, possibly on an on-demand basis, to the harvesting facility.

A water electrolysis system includes: a water electrolyzer configured to electrolyze water to generate gas including oxygen and hydrogen; a gas-liquid separator configured to separate gas phase including hydrogen from liquid phase of the gas generated by the water electrolyzer; a water level detector configured to detect a water level in the gas-liquid separator; a pressure detector configured to detect a pressure of the gas phase in the gas-liquid separator; and a CPU and a memory coupled to the CPU. The CPU is configured to perform: calculating an error of the water level in the gas-liquid separator detected by the water level detector based on the pressure of the gas phase in the gas-liquid separator detected by the pressure detector.

A water treatment system centrally communicates and controls one or more water treatment devices to regulate the use of the one or more water treatment devices. The water treatment system is configured to enable a localized, on-demand supply of purified water throughout a building or a network of buildings. The water treatment system may control a degree of purity (e.g., water hardness or concentration of dissolved salts) via mixing of purified and unpurified water streams in a controllable ratio (e.g., via one or more controllable valves or one or more tunable water softening units).

A water sanitizing system is disclosed and includes an inner chamber and an outer chamber disposed at least partially around the inner chamber. A lens concentrates solar energy applied to a liquid within the inner chamber. A vacuum source in communication separately with the inner chamber and the outer chamber. The vacuum source controls a pressure within the inner chamber separately from the outer chamber for controlling conversion of liquid within the inner chamber to a gas. The outer chamber, also under vacuum, is an insulative layer to prevent heat loss.

The invention relates to a communications device for non-electric communication between fluidically interconnected devices, the communications device being designed to be mounted in a position in a fluidic overall system formed by the fluidically interconnected devices and to receive and/or emit non-electric signals, in particular in the form of pressure or sound signals, the non-electric signals being transmitted via a line that fluidically interconnects the devices. The invention further relates to a method for non-electric communication between fluidically interconnected devices, the non-electric communication taking place preferably by means of pressure and/or sound signals via at least one line that fluidically interconnects the devices.
