The maintenance of ultrafiltration membrane sewage treatment systems mainly includes the inspection and maintenance of reaction tanks, the inspection and maintenance of various chemical dosing and mixing devices, as well as the replacement and maintenance of fillers and filter materials. Due to the differences in water treatment equipment, the specific content of maintenance also varies.
Regular equipment maintenance can effectively extend the service life of the equipment and make it more durable.
Nowadays, water pollution is becoming increasingly serious, and various types of wastewater are contaminating our water sources. Not only is the surface water resource pollution severe, but the groundwater resource pollution is also not optimistic. Industrial sewage, in particular, poses the most serious threat. Therefore, many companies are now using water treatment equipment to purify water. But do you know how to maintain water treatment equipment? Below are the maintenance methods for pure water and sewage systems.
The maintenance of pure water systems mainly includes the replacement of filter media, chemical cleaning or replacement of ultrafiltration membranes and reverse osmosis membranes, regeneration or replacement of ion exchange resins, as well as inspection and maintenance of other auxiliary equipment.
Generally, the filter media need to be replaced after a period of use. Before replacement, a comprehensive inspection of the interior of the equipment should be carried out before filling with new filter media. Meanwhile, hardware components, gaskets, sealing rings and other parts should be inspected, repaired or replaced.
For ultrafiltration membranes and reverse osmosis membranes, acid cleaning and alkali cleaning should be performed to remove contaminants from the surface of the membrane elements. After cleaning, the membrane elements can either be put into shutdown maintenance or started up for operation.
