What are the advantages and disadvantages of ultraviolet rays?

Released Date: Aug 31,2015 Article Source: Yuanlai Water Treatment

Advantage 1: Ultraviolet rays can generally kill 99% to 99.9% of viruses within 0.5 minutes. 1. It has a high sterilization rate, fast speed and high efficiency. 2. Broad-spectrum property: Ultraviolet light can effectively kill harmful substances such as bacteria, viruses and spores, and has broad-spectrum property. It can remove spores and viruses that are difficult to kill by liquid chlorine method. 3. No secondary pollution: Ultraviolet light is a physical process without the addition of any chemical agents. Therefore, it will not cause secondary pollution to water bodies and the surrounding environment, nor will it leave any harmful residual effects on humans and aquatic life, nor will it change any components in the water. Compared with chemistry, it avoids the dangers and corrosiveness existing in the generation, handling and transportation. 4. Easy operation: It is relatively reliable and convenient for the surrounding environment and operators

Advantages

1,Ultraviolet rays are generally associated with viruses0.5minIt can be reached within.99%~99.9%It has a high sterilization rate, fast speed and high efficiency.

2,Broad-spectrum property: Ultraviolet light can effectively kill harmful substances such as bacteria, viruses, and spores. It has broad-spectrum property and can remove spores and viruses that are difficult to kill by liquid chlorine methods.

3,No secondary pollution: Ultraviolet light is a physical process without the addition of any chemical agents. Therefore, it will not cause secondary pollution to water bodies and the surrounding environment, will not leave any harmful residual effects on humans and aquatic life, and will not change any components in the water. Compared with chemistry, it avoids the dangers and corrosiveness existing in the generation, handling and transportation.

4,Easy to operate: It is relatively reliable for the surrounding environment and operators, easy to manage, and easy to achieve automation.

5,Compared with other methods, ultraviolet light has a very short contact time and requires very little space, which can save a large amount of land and civil construction investment. The operating cost is also relatively low. At the level of treating a thousand tons of water, its cost is only that of chlorine efficiency1/2.

Disadvantage

1,Insufficient ultraviolet radiation dose will not effectively kill pathogens. Pathogens may self-activate under photosynthesis or the "dark" mechanism and have no lasting ability, thus failing to solve the problem of re-pollution in the subsequent pipeline network.

2,Substances, minerals and suspended matter in water will deposit on the surface of the ultraviolet lampshade, affecting its effect.

3,Turbidity andTSSThe marketing of ultraviolet rays is relatively large. In the application of low-pressure ultraviolet lamps, water ingressTSSThe high limit is30mg/LWhenTSSNot higher than20mg/LLess than10mg/LIt will reach a good level Effect.

: EDI ultra-pure water system

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.

: Non-negative pressure water supply equipment

The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.

: Constant pressure water supply equipment

Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
