Shell filter based on Houshan walnut shell particles was the appearance of

Brown, no rot, no spots, toughness, wear resistance. Mainly used in highly automatic control water injection filter, sewage filter, filter into the well and so on. It is a necessary water purification material for oil and water separation in oil field, refinery, petrochemical project and other environmental protection projects. It has the advantages of wear resistance, no decay, no caking, easy regeneration and so on. It needs to be filled with 5-10% every year.

1, with many aspects and microporous, dirt interception is strong, oil and suspended solids removal rate is high.

2, with multi edges and different particle size, forming a deep bed filtration, enhanced oil removal capacity and filtration rate.

3, with hydrophilic, non oil and appropriate gravity, backwashing easy, strong regeneration.

4, hardness, and after special treatment is not easy to corrosion, do not replace the filter media, only add 10% per year, reducing maintenance costs and maintenance time, improve utilization.

This filter has high hardness, abrasion resistance, resistance, resistance to pressure is 23.4KgF, stable chemical performance, does not dissolve in acid, adsorption and interception capability, the adsorption rate was 27 - 50%, good hydrophilicity oil resistance, the proportion of g/cm31.25, slightly larger than the water filling proportion is 0.85g/ cm3, anti washing regeneration. Compared with other media, its advantages are directly used to filter the water before wash, low operation cost, low backwashing intensity (6.71/S., M2), fast filter (24 - 26/n) effect. The effect of no water treatment in the oilfield is remarkable, the oil removal rate reaches 95%, and the oil content drops below 5mg/l.

Common specifications: 0.5-0.8mm (24-35 mesh), 0.8-1.2mm (16-24 mesh), 1.2-1.6mm (12-16 mesh), 1.6-2mm (10-12 mesh)
