Stable application of flow-through UV sterilizers made from stainless steel.

　　Flow-through ultraviolet sterilizers typically use stainless steel materials. Both the interior and exterior surfaces of the sterilizer’s main body are polished to enhance UV irradiance. Flow-through UV sterilizers are primarily used for disinfecting daily drinking water in residential areas, residential communities, office buildings, hotels, restaurants, water treatment plants, and other similar settings. They are also employed for disinfection in the food industry, the electronics industry (for ultra-pure applications), military camps, and field supply systems. Additionally, they find application in laboratories, where they effectively disinfect pathogenic waste with high concentrations. These sterilizers are suitable for disinfecting urban pollution, media contamination, household pollutants, and industrial waste. They are also used for disinfecting recreational facilities such as swimming pools and amusement parks.

　　Ultraviolet sterilizers are an essential component of recirculating aquaculture systems, used for water disinfection during the rearing of various species, fish farming, and the purification of aquatic products. Water recirculation is the primary feature of this type of aquaculture system, which distinguishes the evaluation of ultraviolet sterilization effects from those of conventional overcurrent UV disinfection systems used in industrial water treatment. Over the past two decades, research and application of recirculating aquaculture systems have received increasing attention. As water resources become increasingly scarce and regulations on discharging wastewater from traditional pond-based aquaculture grow ever stricter, it has become imperative to conduct further research and develop recirculating aquaculture systems for aquatic animal farming.

　　The superfluid sterilizer is characterized by a high flow rate; the fluid passes through the quartz casing in no more than one second. Therefore, the ultraviolet intensity of the sterilization lamp must be exceptionally high—typically exceeding 30,000 μW/cm² on the surface. To achieve such a high UV intensity, it is essential to select a high-intensity, high-power ultraviolet germicidal lamp.

　　If you’d like to enhance the disinfection effect by extending the contact time, you can generally choose a longer lamp, build a longer UV sterilizer, or treat the stainless steel exterior into a rotating structure to prolong the water’s residence time.
