Chengde security filter precision filter quality filter manufacturers

Chengde security filter precision filter quality filter manufacturers supply a precision filter, precision filter technology Chengde principle: 5μ security filter settings before reverse osmosis (RO), electrodialysis (ED) body, the intent is to avoid large water particles into the reverse osmosis membrane or electrodialysis membrane, to ensure the normal operation of RO, ED's. Security filter is a vertical cylindrical device, built PP melt spray filter, filtering accuracy 5μm; suitable for containing suspended impurities lower (turbidity ≤1mg / l) of water depth purification. Second, Chengde Ultrafilter Precautions 1. Check each valve switch sensitive. 2. The inlet valve, the valve should be normally open, as long as the ability closed during maintenance. Equipment maintenance is completed, should be open for use. 3. the import pressure gauge accurate. Normal operation 4. open the valve, then moved into the valve (normally the valve, inlet valve should be normally open), the device that is open. 5. The open air vent until no bubbles after closing air vent. 6. The operation period, recording outlet pressure P2, the inlet pressure P1, when the differential pressure> 0.1Mpa, it is necessary to replace the filter corresponding device. 7. outage under normal circumstances, the security filter must not be closed as long as the equipment maintenance ability when closed, open immediately after the service is completed. Closed first inlet valve when closed, and then closed the valve, the device that is closed. Third, Chengde precision filter using Notes 1, the operation should avoid pressure shock, stop reverse pressurization. 2, when the filter, the pressure drop between the downstream flow was significantly greater than 0.3Mpa or lower, should consider to replace the filter. 3, if the filter temporarily jobs, do not dry the filter, and should be soaked in a suitable sterile solution (or write such a solution in the case), should be sterilized before use solution from scratch, wash clean . 4, if the filter steam sterilization, it is first necessary to drain the steam pipe condensate, steam pressure should not exceed 0.1Mpa, together with the filter, pressure drop between the upstream and downstream do not exceed 0.015Mpa, if wet filter states steam sterilization, after the steam should be preceded by clean compressed air will filter the aspirated fluid drained, otherwise it will damage the filter when passed into steam.
