Pressure Control Valve of the RO system
In reverse osmosis (RO), the water carry from high concentration to low concentration, but because that does not happen naturally, pressure must be put in to the high concentration side of the membrane to energy water molecules to the other side.
If drawn so, the system operating pressure is regulated with the operate of pressure control valve. It is always preferable to turn the valves slowly during pressure adjustment and flow control.
The operating pressure is theme to the salinity and the condition of the raw water. suppose salinity is constant, the higher the condition, the lower the pressure and lower the temperature, the higher the pressure.
