Technical guidance of walnut shell

Walnut belong to soft plant polishing materials, with excellent wear resistance, it is a kind of the crushing, screening, skimmed, polishing, steamed wash, drug treatment more word processing technology from adsorption effect good filter material.
Walnut shell technical guidance: project detection test data project detection test data oil removal rate 90-96% backwashing strength m3 / m2 25. Suspended 95-98% removal h water to rinse 0.32 MPA pressure filter speed 20-25 m/h maintenance way every year added 5-10% density 1.26 g/cm3 density of 0.85 g/cm3 walnut shell filter chemical analysis project detection test data project detection test oil removal rate 90-95% of the 25 m3 / m2 wash strength.NO. H suspended solids removal filter speed 95-98% water washing 0.32 MPA pressure filter speed 20-25 m/h maintenance way every year added 5-10% specific gravity of 1.5 g/cm3 density of 0.8 g/cm3 (a)
1, has many characteristics of sexual and microporous sex, cut corrupt capability is strong, oil and suspended solids removal rate is high.
2, have more sex and different particle size edges, forming deep bed filtration, enhance the ability and the oil removal filter speed.
3, has close water don't close the oil and appropriate proportion, the wash easy, regeneration strong.
4, hardness, and special processing is not easy to corrosion and without replacement filter material, every year, adding only 10%, reduce maintenance costs and maintenance province time, improve efficiency.
