In case we feed BWRO (one pass) with 10 ppm total TDS, can we get purified water less than 1 ppm? Using high rejection Ro membrane , what the side effect to use this arrangement.
thanks Virendra Kumar , but I meant if we feed one pass with TDS less than 10 ppm ? the same as duple pass Ro second pass is feeding with low TDS less than 10 ppm and get finale product less than 1 ppm , is it ?
