Vontron ULP11-4040
ULP series of ultra low pressure aromatic polyamide compound membrane element newly developed by VONTRON can work under low pressure to reach as high permeate flow and rejection same as a regular low pressure membrane element, and is applicable to desalination of surface water and underground water. It operates under approximately 2/3 of the operating pressure of regular low presure composite membranes, which cn decrease the investment costs for such releveant facilities as pumps, pipelines, and containers, etc. and the operating cost for the RO system, thus increasing the economic effciency.
ULP series RO element normally suitable for treatment of surface water, underground water and municipal water with TDS isless than 2000 ppm. It is mainly applied in bottle water, drinking water, boiler replenishment water, food processing and pharmaceutical manufacturing industries and other fields.
