Reverse Osmosis and Nanofiltration

Reverse Osmosis (RO) and Nanofiltration (NF) are high pressure membrane processes which operate a total or partial demineralization of the filtered waters.

TECN.A. designs all types of reverse osmosis and nanofiltration systems, using spiral wound membranes.

The main applications we have developed, either on primary waters or wastewaters, are:

 The pre-assembled choice of models we fabricate ranges from 250 lt/h up to 36.000 lt/h.

Chemical products of our production and conception, such as antiscalant and cleaners for membrane cleaning are also available .
