- Abstract:
- The intelligent backwashing system for filters is an important part of the construction of a smart waterworks. At present, in most domestic waterworks, the automatic backwashing control of filters is mainly achieved through manually setting the backwashing cycle of the filter. This study takes a traditional process waterworks as an example. Considering not to increase the equipment cost, it upgrades and transforms the waterworks filtration system based on the existing automatic control conditions of the waterworks. According to the production data of the filter in the test waterworks, mathematical models were established using MLP neural networks and multiple regression algorithms. Time cycle, water level, clear water valve opening, and pressure difference are taken as the trigger conditions for filter backwashing. Combined with PLC control technology, the optimal backwashing cycle is set for the filter to ensure its normal operation and achieve energy saving and consumption reduction. The operation data of the test waterworks shows that the system can ensure the backwashing effect of the filter while extending its operating time by an average of about 7 hours. It is estimated that about 60 391 m3 of backwashing water and 5 110 kW·h of backwashing electricity can be saved each year.
