100 T/Hr Walnut Shell Filter For Petrochemical Industry

The nutshell media filter is one of the principal water treatment process that use sand or other grainy media to remove oil and other suspended substances in produced water. The oil and , suspended substances include various hydrocarbons in crude oil, emulsions, dirt and other organic matter. Nutshell media filtration is commonly used to produced water intended for the reuse or reinjection water.

Nutshell media filter has a deep bed >1 meter of find black walnut shell media. The total media depth typically ranges from 90 - 120cm. Produced  water flows downward through the media and underdrain system, then the filtered water is stored pumped to reinjection wells.

Walnut shells have a natural affinity for oil, causing it to bond to the surface of the media.  Unlike in sand filters, whose captured oil films over the surface, captured oil remains as droplets.  These absorbed droplets will then contact smaller droplets, which coalesce onto the larger droplets and increase the removal rate of small particles over time
