Quality Inspection for UV Sterilizer For Drinking Water - UV steirlizer for water treatment – Guanyu

Disinfection Principle And Introduction

According to the difference of biological effects, UV Rays can be divided into UV-A(320-400nm), UV-B(275-320nm), UV-C(200-275nm) and vacuum ultraviolet. Actually use UV-C in water treatment, and in this waveband near 260nm has been proved to be the highest effect.

GuanYu UV sterilizer set optics, microbiology, machinery, chemistry, electrons, fluid mechanics etc. as one whole. Adopt special designed high efficiency, high strength and long life UV-C light generator, when the bacterium, virus and stuff in water are irradiated by certain dose UV-C (waveband 253.7nm), their cell DNA and structure are destroyed, and cell reproduction cannot continue. Reach the effect of disinfection and purification to water. The spectral line with band 185nm can disintegrate the organic molecule in water, generate hydrogen and free radicals, make organic molecules oxidated into carbon dioxide, reach the purpose of removing TOC.

Advantages

1, High efficient sterilization: normally kill 99%-99.9% bacteria within 1 to 2 seconds.

2, Broad spectrum: Ultraviolet bactericidal broad-spectrum is the highest, can kill almost all bacteria and virus.

3, No secondary pollution: don’t add any chemical agent, so cannot create secondary pollution to water and ambient environment, do not change any ingredients in water.

4, Safe and reliable to operate: traditional disinfection technology such as adopting chloride or ozone, the disinfectant itself are highly toxic, flammable substance. And UV disinfection system has no such potential security risks.

5, The machine Low operation and maintenance cost: UV sterilizer occupies a small area, structure requirement is simple, so total investment is smaller. Lower cost in operation, it costs only half than that chlorine disinfection in kiloton water treatment.

Equipment Features

1, Adopting high efficiency UV-C(LL or LH) UV light: adopting world leading low voltage and high intense UV light tube, light tube’s operating life guarantee above 8000-12000 hours.

2, Adopt high light transmittance, high purity quartz drivepipe., ensure that UV light trough more than 90%.

3, Adopt world advanced constant, high strength UV special ballast , ensure the whole system operate normally in complex condition.

4, The reactor adopts high quality stainless steel(304 or 316L) orUPVC,the inwall of reactor is special polished, to improve the disinfection effect.
