Characteristics of Flow-Through UV Sterilizers
The body of the flow-through ultraviolet sterilizer is made of 304L or 316L stainless steel, both internally and externally. The body undergoes internal and external polishing treatment to enhance UV irradiance, ensuring that during the disinfection process, there will be no instances of incomplete sterilization or disinfection of the items being treated.

On the Installation and Function of Flow-Through Ultraviolet Sterilizers
The flow-through ultraviolet sterilizer consists of components such as a 304 or 316 stainless steel housing, UV lamp tubes, an electronic ballast, a quartz sleeve, and a control box. When selecting the installation location for a flow-through UV sterilizer, the equipment should be installed according to specific requirements. Typically, flow-through UV sterilizers are installed at the outlet of the water tank and at the center of the variable-frequency pump; however, they must never be installed at the pump outlet. Due to the water hammer effect, buffering through pipelines, valves, and pump impellers can minimize the destructive force of water hammer and also reduce the damage that high-pressure in the pipeline network may inflict on the UV sterilizer. Therefore, the UV sterilizer should be installed at the inlet of the pump.

Are you familiar with flow-through UV sterilizers?
The working principle of the flow-through ultraviolet sterilizer is as follows: Wastewater treated by the sewage treatment system flows through a flow-through ultraviolet sterilizer installed in an open-channel ditch. The UV lamps on the flow-through sterilizer emit short-wave ultraviolet light with a central wavelength of 253.7 nm, which effectively disinfects the water flowing through the ditch, thereby addressing the issue of bacterial indicators exceeding the standard in the treated wastewater and ensuring that the discharged water meets or even surpasses the requirements of relevant national discharge and water quality standards.

Maintenance Methods for Secondary Water Disinfection Equipment
The secondary water disinfection equipment consists of a microcomputer control system, a feeding system, a reaction system, an automatic control system, a vacuum suction system, a heating system, and a safety system. During operation, a sodium chlorate solution and hydrochloric acid are quantitatively delivered to the reaction system via the feeding system under negative pressure conditions. In the reaction system, the mixture undergoes negative-pressure aeration, generating a mixed gas composed of chlorine dioxide and chlorine gas. After being absorbed by the absorption system, this mixture forms a disinfectant solution of a certain concentration, which is then introduced into the water body to be treated.

Relevant knowledge about secondary water supply disinfection equipment
As we all know, in urban tap water plants, water from wells and reservoirs is transported via pipelines to storage tanks located in residential communities, hotels, guesthouses, military bases, schools, and other facilities—where it’s then supplied again for user consumption. This process involves secondary water supply disinfection equipment. Let’s take a closer look at this secondary water supply disinfection equipment!

How effective is the disinfection equipment for secondary water supply?
Chlorination is essential in municipal water treatment and water supply systems. However, in industrial production processes, it is often necessary to remove residual chlorine from the water as a pretreatment step to avoid adverse effects on the product. The primary methods for eliminating residual chlorine are activated carbon beds and chemical treatments. The requirements for secondary water disinfection are as follows: Secondary water disinfection in urban areas must effectively inactivate bacteria; the byproducts generated after disinfection must pose no adverse impact on water quality or human health; secondary water disinfection equipment must be economically viable and easy to manage; and the quality of secondary water must meet both domestic and drinking water standards. These requirements pertain to both drinking water quality and hygienic standards for secondary water supplies.
