The Pressure Exchanger allow us to use high pressure pumps sized only for a flow equal to the permeat, as we get 2/3 of the pressurized flow from the PE without energy consumption. A conventional RO plant of this size consume 7-8 KWh/m3 of potable water produced. Our SeaRO ERS plants only consume 2,8 KWh/m3. Seawater: The only long-term, completely reliable source of drinking water. Agua de mar: La unica fuente segura para obtener agua potable ahora y en el futuro.
