ABSTRACT:
An automatic backwashing strainer system is provided for cleaning a strainer with a minimum amount of backwash water. The system includes a long time mode and a short time mode of operation in which the backwashing operation is conducted periodically with a variable duration and a variable cycle time. The system also includes a differential pressure mode of operation in which the backwashing is conducted whenever the pressure drop across the strainer exceeds a predetermined upper limit and continues for a variable time delay after the pressure drop reaches a predetermined lower limit. The particular durations, cycle times, time delays, and modes utilized to control the backwashing are selected in response to the operating conditions of the strainer system.
