MEIQI walnut shell filter material is the use of high-quality pecan shell as raw materials, after crushing, polishing, steaming, drug treatment, two screening processing into a water treatment filter material. Walnut shell filter material has high hardness, wear resistance, good pressure resistance, pressure resistance of 23.4kgf, stable chemical properties, not in acid and alkali dissolution, adsorption fouling capacity, adsorption rate of 27-50%, good hydrophilicity, oil immersion resistance and other advantages.

Walnut shell filter material introduction: the production of walnut shell filter material due to its hardness, ideal specific gravity, porous and multifaceted, and by special physical and chemical treatment (the pigment, fat, grease, electric ion removal clean), so that it has a strong oil removal performance in water treatment, in addition to solid particles, easy backwash and other excellent performance, widely used in oil field sewage treatment. Is to replace quartz sand filter material, improve water quality, greatly reduce the cost of water treatment of a new generation of filter material.

MEIQI production of walnut shell filter material characteristics:

1, with many aspects of microporous, strong pollution interception, oil and suspended matter removal rate is high.

2, with multi-edge and different particle size, the formation of deep bed filtration, enhanced oil removal ability and filter speed.

3, with hydrophobic oil and appropriate specific gravity, backwash easy, strong reproducibility.

4, high hardness, and the special treatment is not easy to corrosion, do not need to replace the filter material, only add 10% a year, reduce maintenance and maintenance time, improve the utilization rate.

MEIQI Walnut shell Uses:

1. Oilfield oily sewage treatment, oil removal and suspended solids.

2, industrial oil industrial water treatment, oil removal and suspended solids.

3, civil water and industrial water treatment, remove suspended solids in water, improve water quality.

It is a kind of degreasing, crushing, screening and other processing of granular, surface pores, adsorption effect is better filter material and polishing abrasive.
