Thank you that we got our Berkey in time. We don't know if you have heard what is going on here in Australia, but we don't have to worry about our drinking water. We are so safe.
Kind regards, Ralph S

Features
    • Filmtec Dow BW30-400 Reverse Osmosis Membrane Instructions:


    • Proper start-up of reverse osmosis water treatment system is essential to prepare the BW30-400 industrial membrane elements for operating service and to prevent membrane damage due to overfeeding or hydraulic shock.


    • Keep the BW30-400 RO element moist at all times after initial wetting.


    • During prolonged system shutdowns, it is recommended that the Filmtec BW30-400 membrane elements be immersed in a preservative solution. This is to prevent biological growth.


    • Avoid any abrupt pressure or cross-flow variations on the spiral elements during shutdown, cleaning or other sequences to prevent possible BW30-400 Reverse Osmosis Membrane damage.


    • During start-up, a gradual change from a standstill to operating state is recommended:

    • - Feed pressure should be increased gradually over a 30-60 second time frame

    • - Cross-flow velocity at set operating point should be achieved gradually over 15-20 seconds

    • - Permeate obtained from first hour of operation should be discarded.


    • Maximum pressure drop across an entire pressure vessel (housing) is 50 psi (3.4 bar).
