1, Sterilizer stainless steel shell warrenty 10 years, other fittings are guaranteed usable one year, free for repair and replace (unconditional man-made factors and force majeure except).

2, Stainless steel reaction chamber adopts imported 304 or 316L, formed through  automatic welding, all the threaded by blunt pull tensile after welding smooth without dead Angle, internal and external polishing high brightness mirror chamber greatly enhanced by ultraviolet radiation intensity, enhance sterilization effect. Thickening chamber design, pressure-bearing  can reach 0.8 Mpa, strict pressure and hydrotest to completely prevent slack phenomenon.

3, UV tubes using Europe imported low-voltage high strength amalgam lamp, use life-span 9000-13,000 hours, equipping efficient electronic ballast further enhance the whole life and the sterilizer effect, the whole sterilization rate as high as 99.99%.

4, The system design is according to  the United States NSF55 "ultraviolet microbial water treatment equipment" standard and national living and drinking water UV sterilizer industry standard CJ/T204-2000.

Ultraviolet (UV) Disinfection System for Aquaculture Water Treatment

The lifeblood of today’s aquaculture industry is the water used to incubate fish eggs and rear juvenile fish. Water abundance and purity continue to decline while disease concerns found in source waters continues to increase. This phenomenon is due in part to the increased demand for water from growing urban areas, continued pollution of our natural waters and the introduction of new, pathogenic micro-organisms to natural waters through a variety of routes: bird, animal and human activities, including ballast water discharge.

Simultaneously, increased consumption of fish due to reported Omega-3 health benefits has led to increasing demands for higher stock densities in the same hatchery footprint. This brings many challenges to a rapidly growing industry, but there are solutions available today which can help to overcome them. Increasingly, fish hatcheries and rearing facilities are evaluating ways to improve the quality of their source water; while off- setting quantity losses through implementation of re-circulating water systems. This is leading more fish hatcheries to install sophisticated water treatment systems to enhance water quality, reduce the possibility of disease outbreaks due to pathogens and balance water needs due to the lack of available water from natural sources.

Ultraviolet (UV) light disinfection systems play an important role in a complete water treatment process in aquaculture facilities. UV disinfection system designs are available in both closed pipe and open channel arrangements to provide the greatest flexibility to the hatchery. UV system design and components have evolved rapidly over time to provide some of the most reliably performing and maintenance free technology in water treatment applications.

With Aquaculture UV system designs unparalleled in performance, Ozonefac is committed to providing superior quality and the latest advancements in UV technology.

Fuctions of UV System for Fish farming:
Water Disinfection is the most common application of UV in water treatment, a fish hatchery could have several locations where UV equipment would be installed. Typically UV systems are installed after all other water treatment technologies used to enhance water quality (i.e. filters, degasifiers, etc.) just prior to the water contacting fish eggs in an incubation facility or fish in a rearing facility. Additionally, UV systems can be used in hatchery recycle loops and in the effluent treatment system which is becoming more common in some regions.

UV systems significantly reduce pathogen counts in incubation and rearing facilities and have proven to be the most cost effective disinfection technology for the inactivation of many types of bacteria, viruses and parasites harmful to many species of fish.
