Factors being considered to buy ultraviolet sterilizer?
There are many UV sterilizers in market. It is difficult for the customers to choose the right products for their disinfection requirement. Herein are some factors being considered in their tool kits to pick the right things.1.The UV dose
The UV dose for the effective disinfection depends on: water quality, light transmittance rate, flow rate, UV illuminance, germicidal standard etc. In addition, the UV dose for disinfection on different bacteria and viruses is different.

The water process for the Yangjiang Prawn Aquaculture Farm is 120-150 MT/hour. The customer uses the 6kw UV system to get a good disinfection. You just need to share with us what bacteria and viruses being disinfected and water specification, then our technical people will work on the specific UV dose and reactor with CFD computer program to get the right solution for you!

4.Quartz sleeve cleaning system
The transmittance rate of UV light in the water will have a big impact on the disinfection rate. The process water with low transparency and more suspended substances will not only raise the cost for the UV system by higher dose requirement, but also add the higher cost of quartz sleeve cleaning system with better cleaning system. If the quartz sleeves are not cleaned properly for a long time, a layer of dirt will adhere to the surface of the quartz sleeve, blocking the penetration of ultraviolet rays, thus affecting the bactericidal effect. We might not use quartz sleeve cleaning system for ultraviolet sterilizers of pure water, tap water and drinking water for cost saving. We already recommend using quartz sleeve cleaner in the UV disinfection system for sewage and aquaculture water to improve the effect of ultraviolet sterilization and save the cost of maintenance. The quartz sleeve cleaners are divided into manual cleaning, pneumatic cleaning, and electric cleaning. 2.UV reactor chamber

3.Selection of control cabinet
| Button Control | With independent control cabinet system with inductance ballast we can realize stable lighting of UV lamp. It has the functions of illumination, temperature, cumulative use time display and alarm. But if something goes wrong, there is no specific code to show and the customer need to check fault code one by one. |

| Control Panel with LED keypad |
With independent control cabinet system with electronic ballast we can realize stable lighting of UV lamp. It has the functions of illumination, temperature, cumulative use time display and alarm. It can monitor output power, output current, voltage and set power in real time.
It has protection/alarm functions when there are malfunctions such as three-phase current input phase absence, input overvoltage, input undervoltage, output overcurrent, output short circuit, equipment overheating, temperature detection, output disconnection, internal memory damage, etc. It can record the latest six fault records, each fault code, the last output power for fault trip, set power, output current, output voltage, DC current, Pressure, module temperature, etc.
There is LED keyboard operation panel for the control system. We can operate the functions such as start/stop, real-time monitoring, power regulation, reminding lamp tube replacement with this LED keypad.
