Usage
The ROEM-VS(G) series reverse osmosis units are used to desalinate pretreated drinking water or well water to drinking water quality using the principle of reverse osmosis.
The systems are used wherever (partially) desalinated water (permeate) is required:
- Boiler feed water treatment
- Cooling water treatment
- Air conditioning technology
- Parts cleaning systems
- Sterilization tasks
- Commercial dishwashing technology
- Car washes
- Laboratories
Functionality
The desalination process in reverse osmosis systems is based on a membrane diffusion process in which pure water passes through a semi-permeable membrane under high pressure and salts, colloids, and other substances are retained by the membrane. The water fed into the reverse osmosis system is divided into a pure water volume flow (permeate) and a waste water volume flow (concentrate). The permeate is temporarily stored in unpressurized or pressurized water storage tanks to cover consumption peaks. The proportion of the concentrate volume flow fed to the wastewater must not fall below a certain minimum, as this can lead to deposits (scaling or fouling) on the membrane surface and a associated drop in system performance. To improve efficiency, the other portion of the concentrate flow rate is returned to the pump and passed through the membrane again together with the fresh water flow rate.
The ROEM-VS and ROEM-VSG series reverse osmosis systems are equipped with a microprocessor control system that controls and monitors all processes. Together with the appropriate accessories, the systems can be operated fully automatically.
