Suggestions for re-treatment method for water mixed with solids and mud after coagulation and sedimentation process?
In case that your questions is how to get more water out and reduce volume of the sludge, try sludge thickening methods starting from the bottom going up. First test flocculents to make sludge more dense, follow by the gravity thickening, lamella/tube clarifier and so on. You may consider membrane thickening, which may be more costly, while it may be more effective.
