Seawater
Along with the thermal process, reverse osmosis – a process that is based on membrane technology – is becoming increasingly popular for the industrial desalination of seawater. However, the complexity of these kinds of desalination systems requires plant components that meet high technical standards.
It is important to note that the energy requirements of the reverse osmosis process can be reduced considerably, since the high-pressure energy of the flow that is left at the end of the desalination process can be used for energy recovery: By means of a Pelton turbine, this pressure energy is led back into the system by coupling the turbine shaft directly to the pump shaft. This helps to reduce the power of the drive that needs to be installed for the high-pressure pump. As a result, up to 45 % of the drive energy required can be led back into the system.
Hydrols B.V. offers plant solutions and complete pump trains that consist of a high-pressure pump, a drive motor and a Pelton turbine.
