How should the maintenance and upkeep of wastewater UV disinfection equipment be carried out?

Wastewater UV Disinfectant The disinfection effect depends on the product of the ultraviolet dose, ultraviolet intensity, and irradiation time that bacteria and viruses in the water can receive. When the ultraviolet dose reaches a certain level, the ultraviolet light energy will cause bacteria, viruses, and other pathogenic organisms in the water to... DNA The internal structure is damaged, losing its activity and thereby achieving disinfection and purification of the water quality. As the price of UV disinfectors declines, an increasing number of wastewater treatment plants are adopting UV disinfectors to treat their effluent.

 

The effectiveness of a UV sterilizer primarily depends on whether the bacteria and viruses in the water receive an adequate UV dose. Once the UV dose reaches a certain level, the energy of the UV light will cause the bacteria, viruses, and other pathogens in the water to... DNA The structure is damaged, which causes the microorganisms to lose their activity and be effectively eliminated, thereby purifying and disinfecting the water quality. Nowadays, as the price of UV disinfection equipment has dropped, many wastewater treatment plants have started adopting UV disinfection systems to treat their effluent. So, how should the equipment system of a UV disinfection unit for wastewater be maintained and serviced? Below, we’ll discuss this in detail. Ultraviolet Disinfection Equipment Manufacturer Let me give you a specific introduction!

 

I. Cleaning the Surface of the Glass Sleeve of the Wastewater UV Disinfection Unit

 

The wastewater UV disinfection unit can effectively eliminate bacteria, viruses, and other pathogens present in the water. DNA The structure is disrupted, causing these harmful substances to lose their activity and reproductive capacity, thereby killing them and purifying and disinfecting the water. Currently, with the widespread adoption and increasing popularity of ultraviolet disinfection systems—and given the growing attention they’ve received from many countries—this technology will continue to develop and improve further. 。

 

To ensure the disinfection effectiveness of the equipment, the glass sleeves must be cleaned regularly. This is essential for effectively maintaining the sterilization and disinfection performance. When cleaning the sleeves, please pay attention to the following:

 

( 1 )   First, thoroughly clean away any debris from the surface of the wastewater UV disinfection equipment.

( 2 ) You can use a cleaning agent to clean the casing; the cleaning agent should be a weak acid or a glass cleaner, among others.

( 3 )   During the cleaning process, personnel should wear rubber gloves and use soft cloths to scrub the surfaces.

( 4 ) After the glass sleeve has been cleaned with a cleaning agent, it should be rinsed thoroughly with clean water to ensure its surface is completely free of residue.

( 5 )   After cleaning is complete, reinsert the glass sleeve into the device and connect the other connectors properly.

 

The cleaning system of the wastewater UV disinfection unit also requires maintenance: All air piping systems must be inspected regularly for air leaks. If any leaks are detected, they should be promptly replaced and repaired. The cylinder rods should be cleaned regularly to ensure smooth rack cleaning and prevent issues such as rack cleaning creep or jamming.

 

 

II. Maintenance and Cleaning System for Wastewater UV Disinfection Units

 

( 1 ) The water mist separator is primarily of the manual drainage type. Therefore, when the water level in the filter cup reaches... 1/3 At high levels, you must manually drain the water by rotating the knob at the bottom of the cup body, thereby enhancing the ability to separate water from mist.

( 2 ) It is necessary to periodically check whether the pressure of the filter and pressure-reducing valve meets the specified requirements. Additionally, you should monitor the water accumulation inside the filter cup. When the water level in the filter cup reaches a certain capacity, the filter’s pressure-reducing valve will automatically drain the accumulated water, thereby ensuring the system operates smoothly.

( 3 ) Before use, check whether the oil level inside the tank is maintained within the specified range; if it’s insufficient, add oil to the appropriate level.

( 4 ) Open the drain valve of the gas storage tank weekly to remove accumulated water from the tank.

( 5 ) Regularly inspect all air piping systems for air leaks;

( 6 Regularly clean the cylinder rods to ensure smooth rack cleaning, and prevent any crawling or jamming during rack cleaning.

 

III. Maintenance and Servicing of Ballast Boxes for Wastewater UV Disinfection Units and Central Control Cabinets

 

( 1 ) The operation of the air conditioner in the ballast box must be checked daily to ensure its cooling performance.

( 2 ) Regularly remove dust from the surface of the electrical control cabinet;

( 3 ) Check the operation of each ballast daily to ensure that every ballast is functioning properly.

( 4 Every day, it is necessary to check the data displayed on the human-machine interface of the central control cabinet, as this data includes whether the current, voltage, operating status of the lamps, cabinet temperature, UV intensity, and automatic cleaning status are all functioning normally.

( 5 ) Regularly check whether the various connecting wires inside the cabinet have become aged or come loose.

 

IV. Maintenance and Servicing of the Water Level Control Device for Wastewater UV Disinfection Units

 

( 1 ) Fixed overflow weirs should be cleaned regularly after installation.

( 2 During operation, the flap-type overflow weir needs to adjust the water level inside the tank according to changes in water volume, thereby ensuring that the water overflows the first lamp tube while keeping it within the specified range. 6 Within centimeters;

( 3 ) Regularly check whether the fixing screws of the flap-type overflow weir are loose.

( 4 ) The electric overflow weir gate can automatically adjust the water level according to changes in water volume. Its maintenance procedures are as follows:

a Regularly lubricate the motor and bearings, and check whether the motor wiring is loose or otherwise damaged.

b Regularly remove dust from the motor and take proper measures to prevent moisture and rain.

 

Ultraviolet disinfection technology boasts advantages such as high efficiency, broad-spectrum effectiveness, low cost, long service life, no need to add any chemicals, and no generation of secondary pollution. As a result, it is increasingly being applied to the sterilization and disinfection of drinking water, food products, production water in the pharmaceutical industry, industrial recycled water, and wastewater. In many wastewater treatment plants, the use of UV disinfection equipment for effluent disinfection has yielded excellent results.
