How to choose the filter tank backwashing pump? 1. frequency of BackwashingDuring the normal operation of the filter, due to the interception of many dirty and miscellaneous substances on the surface of the filter layer, the gap of the filter material is blocked, resulting in increasing pressure losses and decreasing water output, which cannot meet the water quality update requirements of the pool, at this time, the filter should be backwashed to wash away the accumulated impurities. Therefore, since the filter begins to filter the waterway filter, the time required for backwashing is called backwashing frequency. If one of the following conditions occurs, the filter should be backwashed:1) the head loss of the filter running to the filter layer is increased by 0 compared with the head loss when cleaning the filter layer. 06MPa or reach the pressure difference value specified by the filter manufacturer. according to relevant information, the self-resistance loss of quartz sand filter is about 0.02 ~ 25
Cleaning of oil filter for aeration fan After a long run,Calcium and iron scale in water are easily deposited on the aeration diaphragm,The scale will block the holes of the aeration plate and affect the aeration effect,Greatly reduce the oxygen filling capacity and stirring performance.Expert in science and technology,It is recommended to clean the aeration device regularly,The cleaning cycle should be determined according to the operation.1. drain the aeration tank,Wash with water and brush or high pressure;2. drain the aeration tank,Remove the aerator,Cleaning one by one;3. the aeration group moves out of the aeration tank,Wash the aeration device one by one;4. clean (acid) with automatic cleaning device during operation ).According to research,It is most efficient to clean the aeration plate by acid pickling method.The whole acid pickling process does not affect the normal operation of sewage treatment,It is of great significance for the maintenance and extension of service life of the aeration devi
