Water treatment device (1), in particular for desalinizing and/or distilling and/or purifying water, through solar energy, wherein the device (1) comprises a support structure (2) having at least a first surface (5) and a second surface (6) extending between an upper part (3) and a base (4) of the support structure (2), at least one photovoltaic element (7) transparent to infrared radiation which is connected to the support structure (2) at the first surface (5), wherein the photovoltaic element (7) is part of a photovoltaic circuit (22) for the generation and storage of electrical energy, at least one condensation plane (8) connected to the support structure (2) at the second surface (6), wherein the condensation plane (8) comprises a duct (9) for receiving water to be treated and for leading a residue of treated water to the base (4) of the support structure (2), a collection tank (17) for collecting the condensed water on the condensation plane (8), at least one hydraulic apparatus (14) connected to and powered by the photovoltaic circuit (22) to regulate the flow of the water to be treated, and a control unit (18) connected to at least the photovoltaic circuit (22) and the hydraulic apparatus (14).

A liquid treatment device (1), comprising a casing (2) having a liquid channel (23) connecting a liquid inlet (21) and a liquid outlet (22). Electrode elements (31, 32) in the channel (23) are configured to apply an electric field to a liquid in the channel (23). A first electrode element (31) has an electrode wall having a plurality of liquid passages (34) therethrough, and is preferably made of an electrically conductive sintered material. The wall of the first electrode element (31) is arranged transversely to a liquid flow when it flows in the channel (23) so as to be traversed by the liquid flow, preferably without being circumventable by the liquid flow.

Method for the production of a biological material (BSA3) obtained from the treatment of biological materials associated with the civil wastewater purification cycle, comprising the following steps:A1) extraction of a biological starting material (BSA0) downstream of a thickener (6) of the civil wastewater treatment plant;A) oxidative reaction of the starting material (BSA0), with the addition of ferric chloride (FeCl with generation of a second biological material (BSA3), having a pH of between 9 and 10 and containing hydrolysed proteins, calcium sulphate, iron ions;D) dehydration of the neutralized biological material (BSA3) with separation of a part in the solid state ready for use and a post-dehydration liquid component;D1) transfer of the liquid component to the inlet of the purifier for a new purification and treatment cycle.

The present invention relates to a small device that generates sodium hypochlorite by electrolyzing tap water. It generates sodium hypochlorite on-site by electrolyzing tap water and salt, allowing it to be used as sterilizing water. It also enables the provision of low-concentration sodium hypochlorite by measuring the concentration in real time and controlling the flow rate and current supply. Furthermore, by drawing out a certain amount of electrolytic water from the electrolysis cell and circulating it to mix with the incoming diluted brine, scale-causing components such as fine particles and cations in the incoming diluted brine are neutralized through pretreatment, thereby effectively preventing electrode adsorption of scale components through a surface-activating cleaning action.
