HTRO Mini

New! HTRO Mini 

Introducing the new Hybrid Tubular RO (HTRO) Mini! It combines the power of the XF and RO Mini along with a tubular style membrane housing for higher solids, tangential filtration. Now you can prefilter your solution before using the attached spiral membrane or use the tubular filter exclusively! Unlike traditional hollow fiber type tubular membranes the unique housing supports the polymeric membranes in perforated stainless tubes. This allows for much higher operating pressure, including those membranes with larger rejections. By having a greater range of operating pressure the operator can also achieve different rejections using the same membrane.

The tubular housing is available in both a small two tube and larger eighteen tube (shown) construction. Below is the list of available tubular membranes.
