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.

Plasma discharges and electromagnetic fields may be applied to a liquid, such as water, for desalinization purposes and to treat unwanted material in the liquid.

The ParaDice Process System is the interconnection of a renewable power source to power an ocean water electrolysis apparatus comprising a water container, an electrolysis cell, optionally a precious metal harvesting probe, a filtration system, and a settlement pond wherein the hydrogen generated as a result of electrolysis is supplied to either a hydrogen combustion engine or hydrogen turbine to power an electricity generator thereby creating a renewable zero carbon emission electric power generation system. The hydrogen gas is collected by a chlorine scrubber and transferred to either a hydrogen combustion engine or a hydrogen turbine. Where a hydrogen turbine is embodied the waste heat created therein is used to generate electricity and increase the performance of the filtration system and settlement pond.

Described herein is a faucet arrangement, comprising a faucet unit and an electrolytic cell unit. The faucet unit is adapted to release water. The electrolytic cell unit is integrated with the faucet unit, and is adapted to release a controlled dosage of copper ions to water released by the faucet unit.

A device for treating a flow of water having a chamber (1) through which the flow of water passes. in the chamber (1), a voltage with alternating polarity is fed to two electrodes (15a, 15b) of at least one electrolysis device, whereby particles of the electrode material are released to and entrained by the flow of water. The particles in the flow of water are mixed in at least one nozzle (45) of a vortexing device.

The invention provides an electronic domestic appliance (1000) comprising a decalcifying apparatus (1) for purifying an aqueous liquid, wherein the electronic domestic appliance (1000) comprises an electronic connector (110) for connecting to an external AC power source wherein the electronic connector (110) is functionally coupled with the DC power supply (100), the electronic domestic appliance (1000) further comprising a functional element (1600) wherein purified aqueous liquid is applied and/or stored.

The physical water treatment device, in particular in a flexible water inlet (1), comprises at least one pair of electrodes (2) for water galvanization and at least one means for inserting and fixing the electrodes (2). The means for inserting and fixing the electrodes (2) together with the electrodes (2) form an integral body (3), the resulting shape of which is adapted for the insertion into the flexible water inlet (1). The integral body (3) completely blocks the flexible water inlet (1) and is hollow so that the water flowing through the flexible inlet (1) flows through the electrodes (2) of the integral body (3). The electrodes (2) form a flow-through galvanization system in the integral body (3).

Methods for generating methane from animal waste by anaerobic digestion using bacteria. A screen separator removes suspended solids greater in size than a predetermined size ranging from about 50μ to about 150μ. An electrocoagulation unit electrochemically hydrolyses the waste, causing particles to settle out. A dissolved carbon air flotation has a CO.sub.2 bubbler for separating large particles from small particles by flotation. An anaerobic digester produces biogas. The digester has a biocurtain for growing the bacteria and a heat exchanger for heating the bacteria. The biocurtain surface is convoluted to retain the bacteria. A membrane module removes CO.sub.2. A knock out pot for removes droplets of water. A scrubber removes water vapor, particulates, and contaminant gas. A compressor boosts pressure. A gas chromatograph monitors the biogas composition. A flare skid lowers excess pressure for safety. Biogas is injected into a local pipeline system. A process control is used for controlling the anaerobic waste digestion system.

Methods, systems, and apparatus, relate to a method for carbon capture from sea water. A first source of sea water into a reverse osmosis chamber. Reverse osmosis is performed on the sea water to produce fresh water and brine. The brine is provided to an electrolyzer. A current is passed through the brine and fresh water, thereby producing a hydroxide solution in a cathode chamber of the electrolyzer. The hydroxide solution is collected and placed into a contacting chamber and new sea water introduced. Precipitates are produced comprising at least calcium carbonate and magnesium carbonate.
