What needs to be checked when a gravity valveless filter is in operation?
Thread Content
RT, after a gravity valveless filter has been in operation for some time, to determine whether it is functioning properly, what aspects need to be checked? ? Please give me some advice! !
1. Check whether its backwash time has increased. 2. Check whether its backwash frequency has increased. 3. Check whether the liquid level after backwashing is higher than the original set value. 4. Conduct water analysis to check whether the S.S. at the inlet and outlet has worsened. If there are any errors in my personal experience, please feel free to correct me!!
It is also necessary to check for any leaks. In winter, it is important to inspect the insulation as freezing can cause problems
