There is disclosed a method and UV reactor for improving the efficiency of treating fluids applied to a UV reactor (2) comprising a longitudinal flow chamber (4) having a longitudinal center axis (22), an input (6) for entry of fluid in the flow chamber (4), and an output (8) for fluid to exit the flow chamber (4), where at least the input (6) of the flow chamber (4) comprises an inlet pipe (10) followed by an inlet cone (12) which as a part of the flow chamber (4) increases the cross section of the channel from the inlet pipe (10) to a cross section of the longitudinal flow chamber (4) of UV reactor (2), said UV reactor (2) having at least one longitudinal UV-lamp (20) parallel to but not coinciding with the longitudinal center axis (22), and where the UV-lamp (20) is arranged such that fluid can flow along a flow path from the input (6) to the output (8) via the flow chamber (4), and so that fluid flowing along the flow path can be exposed to UV radiation as it flows from the input (6) to the output (8) to receive a UV dose, which is characterized in, that the fluid applied to the UV reactor (2) via the input (6) of the flow chamber (4), when passing the inlet cone (12), is applied a uniform helical flow path in an extent that all the fluid applied to the UV reactor (2), within the operation range of the current UV reactor (2), at least passes at least one UV lamp (20) at a distance to receive at least a prescribed UV dose related to the current UV reactor (2), during passing of the fluid inside the UV reactor.

A tempered hot water delivery system configured to prevent or reduce colonisation of Legionella bacteria in tempered water delivered from the system to one or more outlets in a facility. The system comprises: a thermostatic mixing valve comprising; a hot water inlet for connection to a supply of hot water at a temperature of at least 60° C., a cold water inlet for connection to a supply of cold water, a tempered water outlet for supplying tempered water obtained from mixing the supplied hot water and cold water to provide tempered water at a temperature of between 36° C. to about 53° C. to at least one tempered water outlet of a facility, a recirculating inlet for connection to a recirculating water line circuit; and a recirculating water line circuit comprising a circulating return line connected to a circulating return outlet from the facility and to a water inlet feed line for connection to an inlet of a water heater and storage tank for providing the supply of hot water, the recirculating water line circuit further comprising a thermostatic element configured to introduce hot water to the recirculating water line circuit to maintain the temperature of water in the recirculating water line circuit during periods of little or no draw-off.

A system for sanitizing a drinking water-carrying device includes a filter candle that can be installed in a filter head. The filter head has one inlet and one outlet, and the system includes a sanitizing cartridge which can replace the filter candle. The sanitizing cartridge includes a sanitizing agent that can be flushed into the drinking water-carrying device via the filter head.

A method of water treatment includes providing water that includes at least one contaminant. An effective amount of at least one filter media is added to the to the water that includes at least one contaminant. The water and the at least one filter media are agitated to form a homogeneous mixture. A cationic biopolymer is added to the homogeneous mixture of water and the at least one filter media. The water is separated from the at least one contaminant and the at least one filter media.

A sterilizing module includes a main body and a light source. The main body includes an inner surface, an outer surface and an internal space to treat a target substance in a fluid and connected an inlet and a outlet. The light source is configured to emit light toward the internal space to sterilize the target substance in the fluid. The light source includes a substrate and a plurality of light emitting structures disposed on the substrate. The plurality of light emitting structures is disposed to be spaced apart each other. A first distance between two light emitting structures is adjacent to each other varies depending on a second distance from each light emitting structure to the inner surface of the main body. The second distance has a maximum value and a minimum value of illuminance and a difference between the maximum and the minimum value thereof is about more than 75%.

A liquid dispenser may include a container having an upper opening, a pump provided in the container, a pipe through which liquid discharged from the pump is transferred, a top plate having an upper surface over which liquid flows, a filter assembly provided below the top plate, a base provided below the container, and a thermoelectric element provided in the base to cool the liquid in the container.

A waste peptone disposal system is provided, the system utilizing steam to increase the temperature of the waste peptone and provide active homogenous mixing inside a thermally insulated tank. Steam is introduced through a steam sparging system and directly applied to the waste peptone to reduce noxiousness, allowing the facility to dispose of the processed waste peptone through a wastewater system.

An algae treatment device of the present invention is installed in a ship or a barge and selectively destroys only the air-sacs of algae by discharging high-voltage micro pulses into waters of interest in which green tide or red tide has occurred. Thus, the algae treatment device can efficiently solve green tide or red tide by treating algae using a minimal amount of chemicals, or none at all.
