UV Sterilizer

The UV sterilizers are uniquely designed to permit the water to pass all around the germicidal lamp, taking advantage of the 360° light source. When microorganisms are exposed to this light, the UV energy causes a change in the chemical bonds of the DNA molecules. This alteration results in their inability to multiply and therefore their elimination. The UV sterilizer is one of the cleanest, most non-pollution, non-chemical, without any color and odor and leaves no reside, it is the most natural way to kill virus and bacteria. This technique is often applied for fresh or marine water aquariums, garden ponds, breeder tanks and commercial applications. The UV sterilizer can be in many styles: submersible, float, flow-through, or open channel. The housing material of the flow-through UV sterilizer can be stainless steel or UPVC, the flow rate ranges from 0.2m?/h to 200 m/h. The open channel UV disinfection system has no closed disinfection reactor, it is put directly into an open water ditch to disinfect water flow through it, the treatment capacity of an open channel UV disinfection system can be 1000m/h, or as high as 10000m/h.

UV (ultraviolet) for water treatment

We supply a range of high quality, economical Ultraviolet (UV) sterilization units for water and other technology applications. UVLED (UV LED) is becoming an increasingly important technology. The UV curing industry is growing in the fields of UV-LED curing UV ink, UV adhesive UV paint, UV varnish and other UV sensitive materials. Our main focus has been UV treatment of water, but these other ultraviolet curing technologies are becoming increasingly important.

Typical ultraviolet sterilizer specifications

Note that we offer a variety of options, such as stainless steel housed units, so the below is a guideline as to what is available.

Sizing of a UV for general use

Ultraviolet sterilizer Sizing, bacteria, algae, parasite guideline

A UV sterilizer can have different target organisms. For a koi pond is will be to lower all life – algae, bacteria, fungi and viruses – passing through the ultraviolet sterilizer. The percentage kill in this case will be low, perhaps below 50%, but constant recycling of water through the UV sterilizer has an impact.

Other systems, like a hatchery for fish or shrimp will filter the water to a high level (1 micron filters) and then send the clean water through the ultraviolet sterilizer for a much higher level of sterilization.
