A system for cleaning wastewater, includes: an absorption-biodegradation-denitrification (ABN) reactor, a sequential adsorption reactor, a disinfection reactor, and a sludge anaerobic fermentation reactor. The ABN reactor is an integrated reactor including: a biosorption tank, an intermediate sedimentation tank, a biologically-enhanced degradation tank, a denitrification biofilter, and a secondary sedimentation tank. The pretreated wastewater is introduced into the ABN reactor for removal of chemical oxygen demand, nitrogen and phosphorus; the ABN reactor effluent is introduced into the sequential adsorption reactor for the removal of high-risk pollutants; the sequential adsorption reactor effluent is introduced into the disinfection reactor for the elimination of viruses and other pathogenic microorganisms; the sludge produced by the ABN reactor is introduced into the anaerobic sludge fermentation reactor for alkaline fermentation. The system is effective for removing high-risk pollutants and reducing effluent toxicity, which can be used for the upgrading and reconstruction of the wastewater treatment system.

Water treatment and purification system as disclosed herein relates to a PLC controlled system utilizing a hydroxyl radical generation unit and system to treat polluted water. The system uses a hydroxyl-based advanced oxidation based on natural processes that keeps our atmosphere clean and breathable. This technology creates its own high concentration of hydroxyls that are put through a venturi system into the water to be purified to eliminate unwanted organic compounds such as hydrogen sulfide, pathogens, chloride resistant parasites, and harmful bacteria. The system can also reduce inorganic contaminants including iron and manganese.

A water treatment system having a base assembly and a treatment assembly. The treatment assembly of the system may be configured to filter particulates from water. The base assembly may include a UV reactor operable to disinfect water for consumption.

There is described a radiation source module for use in a fluid treatment system. The radiation source module comprises a plurality of elongate radiation source elements secured to a frame element, each elongate radiation source element having a longitudinal axis; a first motive element secured to a first side portion of the frame element; and a second motive element secured to a second side portion of the frame element. The first motive element and the second motive element are configured to reversibly translate the plurality of elongate radiation source elements in a direction substantially parallel to the longitudinal axis. A fluid treatment system comprising the radiation source module is also described.

A water treatment system having a base assembly and a treatment assembly. The treatment assembly of the system may be configured to filter particulates from water. The base assembly may include a UV reactor operable to disinfect water for consumption.

A UV water treatment system comprising a reactor unit for receiving water therein and a power unit for powering the UV water treatment system. The reactor unit includes a housing and a pair of end caps that sealingly engage the housing at opposing ends. Optionally, the UV water treatment system may have a reduced footprint

A water vending apparatus is disclosed. The water vending system includes a water vapor distillation apparatus and a dispensing device. The dispensing device is in fluid communication with the fluid vapor distillation apparatus and the product water from the fluid vapor distillation apparatus is dispensed by the dispensing device.

A water quality measurement device 1 includes a twin tube excimer lamp 2. The inflow pipe 3 is connected to one end of the inner tube 21 of the excimer lamp 2, and the outflow pipe 4 is connected to the other end of the inner tube 21 of the excimer lamp 2. The detector 5 that measures the conductivity of sample water is interposed in the outflow pipe 4. In the water quality measurement device 1, sample water sequentially flows through the inflow pipe 3, the inner tube 21 of the excimer lamp 2, and the outflow pipe 4. Hence, the channel in the water quality measurement device 1 can be simplified. Additionally, the sample water is oxidized by being irradiated with UV light in the inner tube 21 of the excimer lamp 2. Hence, it is possible to irradiate the sample water with UV light from the excimer lamp 2 efficiently.

A fluid sterilizing device includes a first reaction chamber, a second reaction chamber, a communication chamber and a light source. The first reaction chamber is connected to a fluid inlet. The second reaction chamber is connected to a fluid outlet. The communication chamber is connected the first reaction chamber with the second reaction chamber. The light source is configured to emit sterilization light to enter the first reaction chamber and the second reaction chamber. The fluid inlet allows a fluid to enter the first reaction chamber, the communication chamber allows the fluid to pass through and enter the second reaction chamber, and a flow velocity distribution of the fluid in the second reaction chamber is different from that of the fluid in the first reaction chamber.

A pure water production system includes a filter unit, a clear water storage tank, an ultraviolet light irradiation unit, and an ion exchange resin unit. The filter unit filters water. The clear water storage tank stores water filtered by the filtration unit. The ultraviolet light irradiation unit irradiates ultraviolet light to water delivered from the clear water storage tank. The ion exchange resin unit produces pure water from water delivered from the ultraviolet light irradiation unit. The ultraviolet light irradiation unit includes an ultraviolet fluorescent lamp, and an outer tube configured to allow the water to flow through surroundings of the ultraviolet fluorescent lamp. The outer tube includes an inflow port through which the water flows in, and an outflow port through which the water irradiated with ultraviolet light from the ultraviolet fluorescent lamp flows out.
