The nut

Nut shell powder, since the stiffness of the 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 and other excellent properties, used in oilfield oily wastewater treatment, industrial wastewater treatment and civil water treatment. Is to replace the quartz sand filter material, improve water quality, greatly reduce the cost of water treatment of a new generation of filter material. Nut shell filter material chemical property analysis test item test data test item test oil removal rate 90-95% backwash strength 25m3/m2 h suspended solids removal rate filter speed 95-98% water washing pressure 0.32MPa filter speed 20-25m/h maintenance method annually supplement 5-10% specific gravity 1.5g/cm3 reactor density 0.8g/cm3 (I) features 1, with multi-faceted and microporous, strong pollution interception capacity, high oil and suspended solids removal rate. 2, with multi edges and different particle size, forming a deep bed filter, enhance the oil removal capacity and filter speed. 3, with hydrophilic not hydrophilic and suitable specific gravity, easy to wash, strong. 4, hardness, and special treatment is not easy to corrosion, no need to replace the filter material, only 10% per year, reduce maintenance costs and maintenance time, improve the utilization rate. 1, oil field oily sewage treatment: to oil and suspended solids. 2, industrial oily industrial water treatment: to oil and suspended solids. 3, civil water and industrial water treatment: remove suspended solids in water, improve water quality.
