Walnut Shell Filter for Oil Removal
The Walnut Shell Filter uses the walnut shell as the filter medium. The specially treated walnut shell has a large surface area and strong adsorption capacity, so the removal rate is high. Due to the hydrophilic and non-lipophilic nature, stirring is used during backwashing to make the walnut shells rub against each other during the movement, which is beneficial to the long-term stability of the filter performance.
