Membranes and Filtration

Membranes are universally used for filtration of waters and wastewaters in circumstances where the water quality is predictable and scaling and fouling potential is managed by pre-treatment. Technologies include Microfiltration (MF), Ultrafiltration (UF), Nanofiltration (NF) and Reverse Osmosis (RO), all applying pressure on the feed water side of a membrane/filter to produce treated water. The difference between technologies is the size of the pores, resulting in the removal of different water impurities.

Our Solutions

Clean TeQ provides a full range of membrane systems based on the best available membrane technology. We have sourcing staff around the world that have good relationships with suppliers, ensuring products meet the required specifications at a low cost. For more information about products we supply, see our equipment supply page.

Our HIROX® (high recovery RO) system uses our CIF® (continuous ionic filtration) technology as a pre-treatment to RO, removing di- and tri-valent cations such as calcium, magnesium and heavy metals from the water before it reaches the RO membrane. These ions cause scaling issues when present in high concentration, and their removal before RO allows typical recoveries of 95-99%.

Clean TeQ is also developing a novel membrane, based on graphene oxide. It will require less energy in operation and avoids many of the scaling and fouling issues of conventional membranes.
