Valveless filter manufacturing standards
Thread Content
Our company is preparing to invite bids for valveless filters and needs to prepare bidding requirements. Does anyone have the manufacturing standards for valveless filters?
Valveless filters are basically made in different ways by each manufacturer. You can specify the flow rate, filtration accuracy, backwash water consumption, pumping time and other indicators. As for the specific production standards, as far as I know, there are no； Another word of advice, the filtration effect of domestic valveless filters is not very good, and the backwash water consumption is large. You can consider some imported filters with program control, and the backwash water consumption is only about 1/5 of the domestic ones.
