HL Type Walnut Shell Filter

Features
1. Utilizes filter backwash without requiring a gas source, featuring low operating costs.
2. The filter material has excellent oil resistance, requiring no replacement; only a 10% replenishment is needed annually.
3. Flexibly adopt series or parallel operation based on the effluent requirements.

Application Scope
Filters primarily used for oilfield and other oily wastewater treatment, utilizing walnut shell as the filter medium with strong adsorption capacity, stable chemical properties, high strength, and good wear resistance. They can be used singly or in series to ensure the quality of the effluent.
