The present invention relates to a filtration unit for filtering the water in a pool or basin, in particular a swimming pool, said unit being mounted behind a wall of said pool, and communicating with said pool via a suction intake (3, 6) and via a delivery orifice to generate a forced flow of water from and back into the pool through a filtration tank and through a suction column by means of centrifugal hydraulic pump. The centrifugal hydraulic pump has an electric motor coupled to a centrifugal turbine housed in a pump body. The electric motor is a sealed, brushless, autonomously controlled motor that is powered at very low voltage and that may advantageously be immersed inside the filtration unit below the level of the water contained in said pool, thereby enabling said motor to be cooled and sound-proofed naturally by the forced flow of the water from the pool, thereby forming a filtration unit and a pool that have low energy consumption.

A fountain has: a water source; a housing; a vortex chamber defined within the housing, the vortex chamber connected to receive water from the water source; a bubble chamber defined within the housing and connected to receive water from the vortex chamber and cause air bubbles to percolate within the bubble chamber; and a water outlet defined in the bubble chamber. A fountain has: a water source; a housing; a vortex chamber defined within the housing, the vortex chamber connected to receive water from the water source; a second chamber defined within the housing and connected to receive water from the vortex chamber; and a plurality of water outlets defined in the second chamber.

A water purification process for treating water containing at least some organic contaminants, and including the steps of pre-treating the water for capturing organic contaminants from solution in a water stream, by passing the water into a spin up bowl to speed up the water stream, forcing the high speed stream through an annular flow passage located centrally of the spin up bowl passing the high velocity stream between a magnetic member and a magnetic ring, thereafter passing the water stream into an energy recovery bowl, directing the flow from the flow passage onto a zinc anode member; and thereafter passing the water stream along a grounded pipe, thereby causing the development of fine particles of calcium carbonates, and capturing the organic contaminants

Water disinfection device configurations and materials are disclosed. In general, one aspect disclosed features an apparatus comprising: a water filtering module including: a rolled stack of sheets, the sheets comprising: an electrode sheet comprising a plurality of porous planar electrodes, a separator sheet comprising a porous planar separator, wherein the porous planar separator is disposed between at least two of the porous planar electrodes, and a perforated pipe extending longitudinally through a center of the rolled stack of sheets; and a case configured to house the rolled stack of sheets, and to direct water through the rolled stack of sheets.

A disinfection device including a pipe with a taper, inlet, and outlet; an ultraviolet laser; a beam steering device and a transparent layer. The laser, located at a smaller diameter end of the pipe, projects a laser beam towards a larger diameter end of the pipe. The laser beam projects through and/or off the beam steering device and through the transparent layer at a plurality of angles in a cycle. The beam steering device reflects, refracts and/or deflects the laser beam at angles such that a laser beam profile projects through part or all of an inner profile of any point along the taper in the cycle. The pipe receives a fluid that passes through the pipe. One of the inlet or the outlet is located at the smaller diameter pipe end and the other of the inlet or the outlet is located at the larger diameter pipe end.

A system for biological nitrogen removal and negative carbon discharge from wastewater with low carbon-to-nitrogen ratio may include a water intake pump, a carbon capture apparatus, a carbon recovery sedimentation tank, an integrated ammonium apparatus, an autotrophic denitrification apparatus and a denitrification sedimentation tank that are connected in sequence by pipes. The carbon capture apparatus may include an anode chamber communicated with the water intake pump via a water inlet pipe and a cathode chamber communicated with the carbon recovery sedimentation tank via a first water outlet pipe. The anode and cathode chambers may be spaced apart by an ion exchange resin membrane. The anode and cathode chambers may be provided with an anode plate and a cathode plate electrically connected to positive and negative electrodes of a power source, respectively. A bottom of the cathode chamber may be provided with aerators connected to a first air compressor by a pipe.
