Membran RO Filmtec BW 30 - 4040 kapasitas 2000 GPD dari USA untuk mesin pengolahan air payau.
Brackish water membranes for RO systems.
These industrial membrane elements come with a hard shell exterior and are recommended for RO systems with multiple element housings containing three or more membranes, as they are designed to withstand higher pressure drops.
