How to select and use UV disinfection equipment for wastewater? Selection of UV disinfection equipment for wastewater

Ultraviolet Sterilizer Manufacturer When selecting a UV disinfection system, it’s essential to fully consider both the user’s interests and the advantages and disadvantages of UV technology. Where conditions permit, if the user can provide effluent discharge standards for wastewater treatment, the UV disinfection system should be selected strictly in accordance with these standards. If the user cannot provide such effluent discharge standards, the UV disinfection system should be chosen based on the principle of selecting a model with higher capacity rather than lower capacity, while also ensuring that the system can accommodate future increases in treatment volume. Importantly, never select a UV disinfection system solely on the basis of its price to meet the user’s affordability—this approach could compromise the effectiveness and reliability of the system.

 

To ensure that wastewater meets the water quality requirements for discharge into a particular body of water or for reuse, select... Ultraviolet disinfection equipment It can achieve the purpose of disinfection and sterilization. When selecting ultraviolet disinfection equipment for wastewater treatment, you should first determine the following points: :

 

(1) Water quality treatment

 

According to the source of wastewater, wastewater treatment mainly includes industrial wastewater treatment and domestic wastewater treatment. The former refers to industrial wastewater treatment and hospital wastewater treatment, while domestic wastewater primarily encompasses sewage generated from daily household activities and municipal wastewater treatment, among others. Wastewater quality includes: TSS Namely, factors such as suspended solids in water, types of wastewater, and their respective proportions. Since different types of wastewater have varying water qualities, different configurations should be selected when choosing ultraviolet disinfection equipment.

 

(2) Water treatment capacity, discharge standards

 

In terms of water volume, the primary considerations are the average flow rate and peak flow rate of the wastewater to be treated. Secondarily, one must also take into account the equipment’s operating hours. 24 Whether to operate on an hourly basis or with intermittent water supply. Additionally, it is necessary to take into account the effluent water quality requirements, discharge standards, as well as bacterial indicators and requirements for both incoming and outgoing wastewater. Based on these factors, a specific design should be carried out regarding the number of modules required for the ultraviolet disinfection equipment used in wastewater treatment, the number of lamps included in each module, and the emission distance of each module.

 

Since wastewater treatment ultraviolet disinfection involves a relatively large number of UV sterilization lamps, and at the same time, there are also many UV ballasts and more complex equipment wiring, the control system for UV disinfection in wastewater treatment becomes correspondingly more sophisticated. Therefore, when selecting equipment, it is essential to first determine factors such as the volume of water to be treated, water quality, and discharge standards.
