Walnut Shell Filter Media

 Product introduction

Walnut shell oil filter materials in wastewater treatment is 

the development and production of lightweight filter material. 

High quality raw materials in the thick mountains, after crushing, walnut high-temperature cooking and repeatedly screening, appearance and decay, yellowish-brown without stain, great toughness.

characteristics:

1.high hardness2.good resistance of abrasion and pressure3.stable chemical ability

4.insoluble in the acid or alkali

5.strong pollutant absorption ability

6.good hydrophilic and anti oil-immersed

Usages:

1) It is widely used in oiled water treatment of oil field, 

    industrial wastewater treatment and the drinking water. 

2) it is also a perfect abrasive by the special procession. 

3) For itself unique performance, it can be used for the detergent accessory material.
