The following are the treatment process of gravel waste water, and our chamber filter press plays a vital role in this process.

The whole process include: 1. Pretreatment. Due to the high solid content of the gravel waste water (high turbidity waste water) and the solids are very fine. So it can not directly treated by chamber filter press, and pretreatment plays a very important role. 2. Flocculation. The treated waste water is pumped into the sedimentation tank, where flocculants are added and mixed evenly with the waste water. The the free water will be discharged, the left thick slurry will be pumped into automatic filter press. 3. Dewatering by chamber filter press.
