The twin-pass Reverse Osmosis System

The twin-pass configuration of modula S-TP  guarantees highest chemical permeate quality and a significant improvement of microbiology. 

If required, both membrane stages can be switched on and off independently of each other. This full redundancy allows maintenance during operation and highest operational safety. 

By combination of submersed and frequency controlled pump, the intelligent system control and operation of energy-saving polyamide membranes DWA ensures a maximum permeate capacity with highest economy and operational safety.
