Backflush/Backwash and Flushing options.

In many systems, particularly where solids are heavy and well defined, dirt accumulates as shown above (A). When the backflush valve is open, (B), the differential pressure between the operating pressure and the backflush system removes the dirt, all without shutting the system down. This simple process is referred to as backflushing.

Backwashing occurs when backflushing is supplemented by fluid flowing, under pressure, in the reverse direction into an empty strainer. This flow reversal backwashes the element and removes the residual dirt. Backwashing is often regarded as a second step, used to remove dirt not removed by backflushing.

(A) Valve closed - dirt accumulated

(B) Valve open - dirt removed thru backwash piping.
