Nutshell Filters

Enhydra offer both traditional and latest generation nutshell filter designs. Our filter designs do not rely on complex mechanical back flushing system, thereby providing a more reliable and cost effective solution for oil and solids removal.

Our most recent development, the Sentinel Filter, is a high-rate, multi-media down flow filter designed specifically for the unique challenges of Produced Water Treatment for injection.  This patented technology is capable of removing solids particles >2 microns and oil to less than 5 ppm Oil in Water.


nutshellThe filter design incorporates the best features of conventional dual-media surface filters and deep bed nutshell filters to offer superior removal efficiency for both oil and suspended solids in one filter.

Enhydra supply full process design, vessel layout and the filter internals including all media, distribution header, collection and back flushing laterals.
