Technology and Design
Nut shell filters are a type of polishing treatment that's often used to clean oily water.
They work by physically absorbing solids and free oils thanks to the nutshell media's affinity with these substances and its coalescing properties.
Dirty water enters the filter from the top and is forced down through the media, where suspended solids and oils are retained.
Treated water exits from the bottom of the vessel, and the filtration step ends either by elapsed time or a high differential pressure signal across the filter.
The media backwashing phase is crucial for removing accumulated contaminants, which are then separated from the media in an external scrubber vessel.
The scrubber retains the media while contaminants flow out with backwashing water, reducing the total required water quantity.
The filtration process is a key aspect of nutshell filters, and it's what makes them so effective at cleaning oily water.
