What is the value of walnut shells

       Walnut shell as a filter material, on the one hand, has the ability of ordinary filter media to intercept the suspended particles in wastewater; on the other hand, the walnut shell filter media can rely on its unique surface physical and chemical properties to remove oil production wastewater through adhesion The medium emulsified oil particles are adsorbed on the surface of the filter material or the agglomerates on the surface of the filter material to be removed.
       Walnut shells can be used as an adsorbent and have been scientifically proven. However, the viscosity and surface tension of the oil adversely affect the adsorption rate of the walnut shell. At the same time, the recovery of oil from the walnut shell has a higher recovery rate than other water media, and it only needs to be compressed by force. Can be achieved. At the same time, walnut shell filter material is suitable for filtering well washing wastewater after pretreatment.
