Factors affecting the effect of ultraviolet rays in water treatment

Released Date: Oct 21,2015 Article Source: Yuanlai Water Treatment

In water treatment, we often use ultraviolet devices. So, what factors can affect the effectiveness of ultraviolet rays? The power of the lamp tube: The power of the ultraviolet lamp tube decreases as the usage time increases, and its radiation effect declines. When the lamp tube is used for a certain period of time, the emission intensity will decrease. In the future, to ensure product quality, the ultraviolet lamps should be replaced in a timely manner before reaching the critical value of their usage time. 2. The power supply voltage should be kept stable to ensure the stability of radiation. 3. Water flow velocity and the distance the water layer is exposed to radiation: When the water flow rate is constant, a large flow area, a slow water flow velocity, and sufficient residence time of the water body within the shell are conducive to disinfection. However, the larger the diameter of the shell and the thicker the water layer, the farther it is from the lamp tube, and the worse the disinfection effect will be. According to the information available, a 30w ultraviolet lamp is suitable for

In water treatment, we often use ultraviolet devices. So, what factors can affect the effectiveness of ultraviolet rays?

1The power of the lamp tube

The power of the ultraviolet lamp tube decreases as the usage time increases, and its radiation effect declines. When the lamp tube is used for a certain number of hours, the emission intensity will decrease. In the future, to ensure product quality, the ultraviolet lamps should be replaced in a timely manner before reaching the critical value of their usage time.

2Supply voltage

The supply voltage should be kept stable to ensure the stability of radiation.

3Water flow velocity, the distance of the water layer exposed to radiation

When the water flow rate is constant, a large flow area, a slow water flow rate, and sufficient residence time of the water body within the shell are conducive to disinfection. However, the larger the diameter of the shell and the thicker the water layer, the farther it is from the lamp tube, and the worse the disinfection effect will be. According to the available information,30wUltraviolet lamp1cmThe water layer efficiency is90%Yes4cmThe water layer efficiency is only40%Left and right. To ensure that the water body has sufficient residence time in the shell and prevent the water layer from being too thick, baffles can be installed inside the shell to improve the 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.
