Applications
Efficient Nanofiltration Process
The OPAMEM™ NANO unit is a membrane treatment system based on the nanofiltration process. The membrane used ensures that the cutting threshold is about one nanometre. OPAMEM™ NANO is generally integrated into a drinking water production system, as it may require an efficient and adapted pre-treatment, depending on the water to be treated (surface water, drill water, groundwater, etc.). Nanofiltration provides the advantage of covering a broad spectrum of parameters under a single technology and also reduces the use of chemical products significantly.
