membranes to treat sludge from water treatment sedimentation tanks
Why do you mix the sludge with water?? And what do you do afterwards with this mixture? Anyway, you should thicken/dehydrate this sludge WITHOUT mixing it with water. There are a lot of methods for this, but on my opinion the best is to use RO membranes. Installing them may be a little more expensive that the rest of the classical methods, but you won't have to worry ever again about chemicals' expenses, or a whole sludge treatment plant maintenance etc
