The purification unit includes a vortex generation part including a support and an opening formed in the support, and a light emitting diode disposed on the support at a position adjacent to the opening and configured to provide ultraviolet light.

Provided is a method for treating a liquid, the method including: receive a liquid; passing the liquid through a generator to cut and shear the liquid and releasing the resultant liquid for use. Also provided is a liquid treatment system including: a source of liquid; a generator in fluid communication with the liquid source which cuts and shears the liquid; a pump which produces liquid flow through the system; and an outlet through which the treated liquid flows.

A fluid cleaning system for cleaning contaminated water sources via at least one cleaning process. The system includes at least one solids dissociation apparatus that includes a housing, at least one insert operably engaged with the housing and is adapted to receive a continuous fluid stream, and a transducer operably engaged with the housing and is disposed about the at least one insert at a distance away from said at least one insert inside of the housing. The transducer is configured to create cavitation, via sonic waves, to eviscerate contaminants in the continuous fluid stream. The system also includes at least one solids separation apparatus operably connected with the at least one fluid treatment apparatus for receiving the eviscerated contaminants provided in the fluid stream. The at least one solids separation apparatus is adapted to separate the eviscerate contaminants from the fluid stream for at least one separation process.

A waste liquid treatment device (20) treats water to be treated that contains at least hydrogen peroxide, by decomposing the hydrogen peroxide. The waste liquid treatment device (20) is equipped with a housing (21), an introduction port (22) that is provided to the housing (21) and that introduces the water to be treated into the housing (21), a discharge port (23) that is provided to the housing (21) and that discharges treated water to be obtained by treating the water to be treated, and one or more channel-defining members (24) that are disposed within the housing (21) and that have a surface that a catalyst is disposed on, wherein the one or more channel-defining members (24) define, between the introduction port (22) and the discharge port (23), a channel (P) for the water to be treated, the channel (P) having a turning in at least one position.

A turbulating apparatus for a drywell includes a frusto-conical sidewall having an upstream inlet and an opposed downstream outlet. The sidewall has an inner surface on which a plurality of vanes are fixed and extend helically between the inlet and outlet. The apparatus hangs from a top of the drywell and turbulates water to prevent the aggregation of debris inside the drywell.

A desalination system (100) having an intake unit (110) providing seawater to a pre-treatment unit (120) connected to a reverse osmosis (RO) desalination unit (130) and a post treatment unit (150). The desalination system (100) is configured to operate without any external addition of chemicals to simplify logistics and regulation concerns. The units of the system are configured to prevent biofouling, scaling and corrosion by mechanical and biological means including high flow speeds, biological flocculation of colloids, and making the water entering the RO units inhospitable to bacteria and other organisms that cause biofouling, hence preventing their settlement and removing them with the brine. Recovery rate is lowered and energy is recovered to increase the energetic efficiency and minerals that are added to the product water are taken from the brine.

The water purifier includes a nozzle (9) in a jacket pipe (1). At least one inlet bore (21) connects an inlet-side section of the jacket pipe (1) to a turbulence chamber (19), which is open towards an outlet-side section of the jacket pipe (1). When flowing through the inlet bore (21), a water stream is deflected and is swirled in the turbulence chamber (19). The rotating water stream subsequently passes through the magnetic field of at least one magnet (11). This efficiently prevents deposits of limestone or scale.

Electrocoagulation (EC) reactors having pellet flow circuits are disclosed. In one embodiment, the EC reactor includes a reactor vessel having a first inlet and an outlet through which a contaminated feed stream is received and discharged, respectively. An EC reaction chamber is located within the reactor vessel, fluidly coupled between the first inlet and the outlet, and configured to be loaded with consumable EC pellets. The EC reactor further includes an EC pellet flow circuit around which the consumable EC pellets circulate as the contaminated feed stream flows through the EC reaction chamber. First and second electrodes are coupled to the reactor vessel and positioned to generate an electrical field. The consumable EC pellets are exposed to (e.g., pass through or circulate within) the electrical field to induce coagulation of contaminants within the contaminated feed stream as the feed stream flows through the EC reaction chamber.

A thickener for dewatering fluids having a vessel with a central well extending proximate a top portion of the vessel to a lower cone-shaped portion, a hindered settling zone, and a compressible sediment layer zone within the lower cone-shaped portion. Eductors housed in inlet wells have an inlet nozzle and a mixing tube to receive slurry to be treated and clear fluid to be mixed with the slurry. The fluid from the eductors is directed in counter circular paths via circular chambers situated proximate the inlet wells, such that fluid flowing in each direction collides and forms turbulence within the central well. Resultant fluid is directed into a lamella-type separator circumferentially located about a portion of the central well, having layered fluid paths directed radially outwards from said center longitudinal axis and upwards towards said vessel top portion through a conical, inclined fluid path, plate structure. The eductors are adjustable with a movable iris for limiting the amount of clear fluid exiting the eductor.

A filtration apparatus whose interior is divided into a filtrate zone and a filtering zone. The filtering zone is adapted to receive a stream of raw-water and a lower portion of its volume is filled with filtering grains, and the filtrate zone is adapted to receive a filtrate obtained from passage of said stream of raw-water via the filtering grains and a perforated member. The apparatus further includes a pressure reducing device in fluid communication with the lower portion of the filtering zone and with an upper portion thereof. The pressure reducing device is adapted to receive a stream of water and responsively to continuously remove filtering grains from said filtering zone and separate filtration residues therefrom by the reduction of pressure conditions thereinside, and direct a stream comprising the stream of water and the separated filtering grains and filtration residues to the upper portion of said filtering zone.
