In a method for extracting boron from feed water, boron is extracted from feed water received as irrigation runoff water from an agricultural source at a pressurized vessel located at a first location, the pressurized vessel including a boron-selective resin bed. The pressurized vessel is uncoupled from the agricultural source, wherein the boron-selective resin bed is boron-saturated. The pressurized vessel comprising the boron-saturated resin bed is transported to a second location. The pressurized vessel comprising the boron-saturated resin bed is coupled to a boron extraction system at the second location. An acid-based solution is injected into the boron-saturated resin bed, causing the boron to be released from the resin bed and into a boron solution. The boron solution is drained from the pressurized vessel into a holding tank.

A urine treatment Installation (1) has a fluid circulation circuit (2) with at least one inlet (3) for supplying urine to the circuit (2) and at least one outlet (4) from said circuit (2). The installation (1) has disposed on said circuit (2), at least one electrolyzer (5) equipped with at least one liquid outlet (52). The installation (1) further has, disposed on the circuit (2), at least: a tank serving to supply urine to the electrolyzer (5) and having the function at least of a buffer tank (7) in order to permit batchwise operation, that is to say batch feeding of the electrolyzer (5) from the buffer tank (7), and an ultrasound generator (6) positioned downstream of the electrolyzer (5) and in fluidic communication with the or at least one of the liquid outlets (52) of the electrolyzer (5).

A method for treating a wastewater comprising phosphates and other nutrients and organic solids comprises feeding the wastewater into an acid gas digester where digestible carbohydrates in the wastewater undergo acidogenesis and acetogenesis forming volatile fatty acids and a suspended solids content to produce an organic acid digest. The acid gas digester effluent is fed into a plurality of harvesting anaerobic digesters connected in series downstream from the acid gas digester. A portion of the solubilized phosphates are precipitated from the wastewater in a first harvesting digester to produce a harvesting digester effluent from the first harvesting digester in the series having a reduced solubilized phosphate content. The harvesting digester effluent is fed into an anaerobic methane digester downstream of the last harvesting digester in the series. Organic solids in the harvesting digester effluent are converted into methane and a digested anaerobic sludge.

A system for treating and/or recycling gray water includes a first receiving tank for gray water, a second receiving tank for treated water and a fluidic treatment circuit between the first and second receiving tanks. The first receiving tank includes an element for oxygenating the water in the first receiving tank and a system adapted to deliver enzymes into the first receiving tank. The fluidic treatment circuit includes a filtration unit, a microfiltration unit including at least one microfilter, a disinfection unit and a membrane ultrafiltration unit.

A method, system, and apparatus directed to an innovative approach for the treatment of stormwater utilizing hydrodynamic separator assembly designed to maximize flow movement for more efficient sediment removal and maximize water flow control.

The invention relates to preventing microplastics from entering the environment. The invention is directed to filtering and compacting microplastics from any effluent, but in particular to filtering and compacting microfibers from the wastewater of washing machines and other appliances. However, the invention may also be applied in any industry where microparticles are generated, e.g. the industrial manufacture of textiles, or in treating roadside runoff, or where microparticles are handled, e.g. in Waste Water Treatment Plants. The invention is a compactor for automatically extracting and compressing microplastics from waste effluent, the compactor comprising; a chamber with an inlet; at least one plate within the chamber moveable between a non-compressing position and a compressing position, and a drive unit for driving the at least one plate; and a discharge outlet arranged to allow the automatic discharge of compressed microplastics.

An apparatus and a method are provided for a mobile reservoir system to provide potable water to desired destinations. The mobile reservoir system includes a waterborne vessel that includes a cargo hold. A collection unit comprised of a material for safe and sterile storage of potable water is disposed in the cargo hold. One or more collectors channel rainwater into the collection unit. Each collector is a sheet of a non-porous material supported on a retractable frame and a plurality of support arms. The sheet provides a surface area for collecting rainwater. A porous material covers the collection unit and operates as a filter for collected rainwater. A retractable cover may be extended over the cargo hold to provide protection to the collected rainwater in the collection unit. A filtration system is configured to offload the rainwater as potable water.

A compact waste combustion system deployed within a portable toilet has a burn chamber that includes a processor, a burner, a trapdoor mechanism configured to seal an entrance to the burn chamber when the compact waste combustion system is operated in a first mode and a waste receptacle configured to feed waste material to the burn chamber through the trapdoor mechanism in a second mode of operation. The processor may be configured to detect presence of a waste in the waste receptacle, configure the system to operate in the second mode and to pass waste into the burn chamber, configure the compact waste combustion system to operate in the first mode after the waste has passed into the burn chamber, and activate the burner when the compact waste combustion system is operated in the first mode and the waste is located in the burn chamber.

A method of removing nutrients and/or toxic substances from water by placing an open-cell foam material together with a biochar material into the water, leaving the foam and biochar materials in the water for sufficient time to adsorb/absorb at least some of excess nutrients and/or toxic substances present in the water, and then removing from the water the open-cell foam material together with the biochar material.

A method of separating an oil and water mixture including contacting the oil and water mixture with a membrane, where only the water in the oil and water mixture passes through the membrane. The membrane includes an alumina support and polypyrrole. A layer of the polypyrrole is hydrogen bonded to an outer layer of the alumina support, where particles of the polypyrrole are in the form of globules having a longest dimension of 100 to 300 nm.
