Small SS304/SS316 UV Disinfection System for Village Waste Water Treatment

Introduction

Open channel UV systems are mainly used at the municipal water/wastewater treatment plants for water recycling and effluent disinfection to ensure a better level of environmental protection.

UV disinfection is an effective and environmentally friendly alternative to the conventional chlorine effluent disinfection. Nowadays more than 15% of 2000 waste water treatment plants in North America have chosen the UV as the primary disinfection method. UV disinfection has proved its safety, reliability, efficiency, and economical characteristics over the years.

Open channel UV sterilizers have been used for waste water, sewage water disinfection in order to achieve a lower environment pollution drainage.

Comparison between Quartz lamp and boric lamp:

Quartz Lamp:

Made by natural quartz with better penetration to UV ray and provide better germicidal result with longer effective usage life but cost much more than boric lamp. Melting point above 1800°C and hardness higher. Be able to be used in water without chemical substances and side effect.

Boric Lamp:

Made by boric. Penetration rate and effective usage life are about 1/2 compare to quartz though cost is much more less than quartz. Melting point below 1400°C and hardness lower. Boric contains chemical substances and could release toxic substances in water which should not be suggested to be used in drinking water e. production line, carbonated beverage production line etc. The design is scientific and reasonable. Its appearance is beautiful. Its operation and maintenance is convenient.

The advantages of using a UV system are many

Effective – Destroys 99.99% of microorganisms;

Chemical free – no harmful chemicals need to be added;

Environmentally Friendly –Go green! UV is an environmentally friendly alternative to chlorine disinfection and has no disinfection byproducts;

Essentially trouble-free – once installed, annual service is usually all that is required;

Reliable – works night and day, 24/7, consistently keeping water safe;

Safe – no handling of chemicals;

Cost-Effective –only lamp & sleeve replaced annually;

Clean – no dirty parts to dispose of;

Quick Process – water flows through the system without need for holding tank or reaction times;

More effective than chlorine or chloramines – especially on some water borne cysts;

Low energy usage – low electrical needs;

FDA Approved – one of only 4 methods approved for disinfection by US Food & Drug Administration (FDA);

Conserves water – The UV purification process does not waste any water;

Taste and odor – Chemical disinfection methods (such as chlorine) change the taste & odor of water and produce byproducts. UV does not.
