From Zhengda
The water treatment of petroleum refining and chemical enterprises is inseparable from the nutshell filter material, because the nut shell filter material has strong hardness, good wear resistance, good pressure resistance, strong adsorption and interception ability, etc., and can be directly used for backwashing before filtration. The sewage treatment effect is remarkable. The nutshell filter material is taken from the high-quality thick-skinned pecan shell, which is suitable for the water treatment of petroleum refining and chemical enterprises. The water treatment of petroleum refining and chemical enterprises cannot be separated from the nutshell filter material.
Gongyi City Jiajinkou Zhengda Water Supply Material Factory is a fixed-point manufacturer of fruit shell filter material and fruit shell polishing material. The large-sized fruit shell filter material has large inventory and low price.
