Warnut Shell Filter Madia/Filter Material/Refractory Material with High Adsorption

Walnut shell filter media
1. Description of walnut shell filter media
Walnut shell filter material is developed and produced to lightweight filter material aiming at oily sewage treatment. Raw material is based on superior quality thick pecan shell, produced through degreasing, crushing, polishing, thermophilic digesting and many times screening. It is yellowish-brown, not decay, without spot, and has high tenacity.

2. Product advantage
1. High hardness, wear resistance, and good pressure resistance.
2. Easy to dissolve in acid and alkali solution.
3. Strong adsorption and dirt-cutting ability. Its adsorption rate is 27-50%.
4. Good hydrophilic, resistant to oil immersed.
5. Easy to backwashing and regeneration. It can be directly used for backwashing before filtering.
6. Low operation cost, and easy to manage.

3. Application of walnut shell filter media
1. It is the ideal filling material for environmental protection equipment.
2. It applies to oil, refining enterprise and other environmental protection engineering for water-oil separation.
3. It is also used in water treatment devices
