How often should the quartz sleeve of a flow-through UV sterilizer be cleaned?

　　 Flow-through ultraviolet sterilizer in the Quartz sleeve In fact, it is used to isolate the sterilizing water body from the UV lamp tube and also determines the penetration rate of the UV light emitted by the lamp tube, thereby affecting the disinfection efficiency of the in-line UV water sterilizer. After the in-line UV sterilizer has been operating for a certain period of time, Quartz sleeve The surface will accumulate some scale and suspended particles, reducing its UV transmittance. So, the flow-through UV sterilizer... Quartz sleeve So, how often should we clean it? Let’s find out together below!

　　When the flow-through ultraviolet sterilizer is in operation, we need to record the UV intensity values regularly every month. When the UV intensity drops by 20%, the system will issue an alert, reminding us that it’s time to clean the housing. It’s worth noting that a decrease in the UV intensity of the sterilizer can also be caused by aging of the lamp or changes in water quality. Therefore, before cleaning, it’s essential to check the lamp’s operating hours and its recent UV transmittance values. The ultraviolet sterilizers used in municipal water treatment plants... Quartz sleeve Usually clean every 2 to 6 months.

　　During the cleaning process of a flow-through UV sterilizer, you should first close the inlet and outlet valves, disconnect the power supply, drain any remaining water from the UV sterilizer chamber, and then remove the UV lamp and... Quartz sleeve . Cleaning Quartz sleeve time You can wipe the surface with an alcohol swab and gauze to remove scale and stains, then clean it thoroughly. This will help prevent UV light from passing through and ensure the sterilizing effectiveness of the flow-through UV sterilizer.

　　Flow-through UV sterilizers have a wide range of applications and are suitable for disinfecting and sterilizing various types of water. However, the actual conditions at each specific site—such as the flow rate and diameter of the UV sterilizer—often differ, making custom design necessary to meet engineering requirements. When customizing UV sterilizers, we need to pay attention to the following points:

　　First, suspended solids and turbidity in disinfectant solutions can interfere with the transmission of ultraviolet (UV) light, thereby affecting the sterilization efficiency of UV sterilizers. Therefore, before customization, it’s essential to understand the water quality and the relevant standards for the specific water body—this information is crucial for both the design of the solution and the selection of lighting fixtures.

　　Second, the UV lamps used in flow-through ultraviolet sterilizers are categorized into three types: low-pressure UV lamps, low-pressure high-output lamps, and medium-pressure UV lamps. It is essential to understand the performance parameters and applicable scopes of each type of UV sterilization lamp.

　　Third, become familiar with the owner’s requirements and the status of fund utilization, and clearly define the arrangement of ballasts for ultraviolet sterilizers. Quartz sleeve the cleaning method. This involves Quartz sleeve Is it manual cleaning or mechanical cleaning? In addition, whether the UV sterilizer is split-type or integrated also depends on the site conditions and available funding.

　　Fourth, the correct determination of the contact time between water and ultraviolet light, as well as the volume of water to be treated, directly influences the number of tubes required for the UV sterilizer.
