Municipal water supply Medium pressure UV sterilizer

Product Introduction

The core working principle of medium-pressure UV equipment is to emit ultraviolet rays covering a wide wavelength range (wavelength range 200nm~400nm), especially the UVC band (200~280nm) through a special medium-pressure mercury lamp. It can emit ultraviolet rays covering a wide wavelength range, including multiple bands that have significant effects on sterilization and decomposition of organic matter.

Ultraviolet rays can destroy the DNA or RNA structure of microorganisms, making them unable to reproduce and survive, thus achieving efficient sterilization and disinfection. In addition, the energy of ultraviolet rays can also cause the molecular bonds of organic matter to break and decompose organic pollutants, such as removing humus and odor substances in water.

Features

High durability light source system

The core is a medium-pressure mercury lamp, which has high power and wide spectrum output, and can continuously and stably emit full-band ultraviolet light. Some devices are also equipped with multiple mercury lamps to increase the intensity of ultraviolet radiation;

Reaction chamber

A properly designed reaction chamber ensures that the ultraviolet rays are evenly irradiated on the treated object, thus improving the treatment effect. The material used is usually a material with high ultraviolet transmittance and corrosion resistance, such as quartz glass.

Control System

Achieve precise control of equipment start, stop, running time, UV intensity and other parameters, automatic cleaning, easy operation and ensure stable operation of equipment;

Broad spectrum sterilization

Full-band ultraviolet rays can effectively kill a variety of bacteria, viruses, fungi, algae and other microorganisms, covering a wide range;

Efficient treatment of organic matter

Decompose organic pollutants in water, such as removing humus and odorous substances in water;

Quick response

Ultraviolet rays react quickly with microorganisms and organic matter, and can achieve the effects of sterilization and decomposition of organic matter in a short time;

No secondary pollution

The ultraviolet sterilization process is a physical action and will not produce secondary pollution like chemical disinfectants.

Advantages of UV rays

1. Ultraviolet disinfection is an environmentally friendly water treatment method that does not require the addition of chemicals and can effectively eliminate water contamination by harmful pathogens;

2. The disinfection effect has been proven by thousands of engineering examples around the world. In the field of drinking water disinfection, ultraviolet disinfection has been widely recognized and applied worldwide;

3. UV light has a broad spectrum of biological inactivation, including bacteria, viruses, and chlorine-resistant protozoa;

4. At low doses, UV treatment is effective in inactivating Cryptosporidium and Giardia;

5. In multi-barrier disinfection strategies, ultraviolet light is a reliable and cost-effective disinfection method, usually combined with chlorine disinfection as a double-barrier disinfection method;

6. Ultraviolet light does not produce disinfection by-products (DBPS) and does not affect the taste of water.

Benefits of a Multi-Barrier Disinfection Strategy 

UV is a cost-effective disinfection method. As one of the double barriers, it can inactivate almost all microorganisms that can be killed by ammonia, including chlorine-resistant protozoa such as Cryptosporidium and Giardia, ensuring the safety of water supply. In double barrier disinfection, the use of UV technology can improve the safety of public drinking water and reduce the risk and liability of accidents for relevant local government departments.

Equipment advantages

1. Fewer lamps are required and the electro-optical efficiency is high.

It combines the advantages of low-pressure and medium-pressure lamps, providing cost and maintenance advantages with high cost performance.

2. Compact footprint.

The optimized reactor design and modular lamp group can be installed in a very small space, thus achieving good economic benefits.

3. Easy to operate and maintain.

with H2O2 or O3 , it can simultaneously meet the requirements of UV advanced oxidation and disinfection treatment .

4. Destroy harmful pollutants.

It is ideal for treating geosmin, 2-methylisoborneol and other chemical pollutants. The treated water fully meets the requirements of drinking water standards.

5. Advanced control system.

An intelligent and flexible control system that optimizes power and oxidant consumption while ensuring UV dose and target pollutant treatment meet treatment requirements.

6. Key control points can be used to demonstrate system performance.

The control system monitors and provides trend lines and outputs for all regulatory requirements including UV dose, oxidant concentration and contaminant reduction.

7. Ensure water quality.

Guanyu UV Systems offers quality assurance including a lifecycle performance guarantee as well as premium systems and spare parts.
