A test shall be conducted on each backflow preventer prior to it being put into service, after any repairs, and a minimum of once a year thereafter. WebForward Flow Tests or Bubble Point Tests on liquid filters require complete wetting of the filter membrane. The Palltronic AquaWIT IV system draws water from the internal tank to fill the filter housing or capsule, flushes it through the membrane to the downstream side, and the filter is then tested using the programmed integrity test.
WebThe Forward Flow Integrity Test In the Forward Flow test, a filter is wetted with a suitable test liquid and a pre-determined gas pressure is applied to the upstream side of the filter assembly. After a stabilization period, the gas flow through the wetted membrane can be measured manually on the downstream side or on the upstream side, using ...
