Pre-Treatment
Ultrafiltration (UF), Nanofiltration (NF)
When wastewater volume requires additional conditioning before reverse osmosis, we integrate UF or NF into the treatment process. These pretreatment technologies remove challenging contaminants and protect downstream RO membranes.

TS Module
High Capacity
The TS spacer tube module series are designed to allow us to house more membrane material in the same volume as a DT module, for difficult water which contains less suspended solids.
