Walnut Shell Filtering Media /Good hydrophilicity, oil immersion resistant water fitler media
A.Walnut shell is very good fitler media in water treament.
Walnut shell filter media introduction
walnut shell filter material is made of high quality Pecan shell of as raw material, after crushing, polishing, steaming, washing, drug treatment, two filter processing and become a kind of water treatment filter material.Walnut shell filter material has high hardness, good wear resistance, pressure resistance, resistance to pressure is 23.4 KGF, stable chemical performance, not in the acid and alkali dissolution, adsorption section carrying capacity is strong, the adsorption rate of 27-50%, good hydrophilicity, oil resistance, etc.
Walnut shell filter material due to the hardness of itself, the proportion of ideal, porous and multifaceted, and the special physical and chemical treatment, the pigment, fat, oil, electric ion removal clean), make it has strong oil removal in water treatment performance, in addition to the solid particles, easy backwashing excellent properties, such as walnut shell filter material has been widely used in oilfield oily wastewater treatment, industrial wastewater treatment and civil water treatment.Is replacing quartz sand filter material, improve water quality, reduce the cost of water treatment of a new generation of filter material.Testing center by the Beijing forestry university, shandong academy of sciences, institute of jiangsu province environmental protection measure, compressive ability of walnut shell grain particle size 1.25 1.60 mm, the average compressive strength limit of 0.2295 KN (23.40 KGF).Walnut shell grain particle size 0.80 1.00 mm, the average compressive strength limit of 0.165 KN (16.84 KGF).Chemical properties of stability, do not contain toxic substances, dissolved in acid, alkali, water volume is small, loss of walnut shell in hydrochloric acid solution was 4.99%, the attrition rate of 3.8% in sodium hydroxide solution, does not cause water quality deterioration.
B.Walnut shell can also used as :
1. [Pore-forming materials] walnut shell
Our factory using foreign advanced technology specialized in vitrified bond grinding wheel hole
porosity materials - walnut shell grains. Compared with the old pore-forming material--refined naphthalene, our product has uniform pores, and it is odorless, non-polluting, easy to use, inexpensive and safe. Moreover, the pore size of the grinding wheel can
be arbitrarily selected. Thus, in 60 years abroad, it has been widely adopted in abrasives industry.
Applicate size (normal): 8 #, 10 #, 12 #, 14 #, 16 #, 20 #, 24 #, 30 #, 36 #, 46 #, 60 #, 80 #, 100 #, 120 #
Specifications can be produced as needed.
2.[Polishing Material] walnut shell
Such polishing materials processed by the special process have excellent wear resistance,
uniform particle size, and ultra-high shell content.
