Primary Coagulant Aid Outperforms Alum, Slashes Operating

Oct 19, 2001· Alum was added continuously to the rapid mix tanks at a dose of 18 mg/L. Several inefficiencies and cost concerns associated with alum use led to investigations and selection of a polymer coagulant product. Alum related problems included high sludge generation with a low 6.8 percent sludge solids content,

MODULE 9.

Rotary vacuum filters are rarely used for dewatering sludges from plants with design flows greater than 20 ML/d. Adoption in handling water treatment plant wastes is limited to thickening lime softening precipitates. Alum coagulation sludge, being more gelatinous, does not dewater readily by suction thus pressure filtration is more successful.

CHAPTER 3 SLUDGE THICKENING Mimoza

SLUDGE THICKENING Thickening is a procedure used to increase the solids content of sludge by removing a portion of the liquid fraction. To illustrate, if waste activated sludge, which is typically pumped from secondary tanks with a content of 0.8 solids, can be thickened to a content of 4 solids, then a fivefold decrease in sludge volume is

How to Treat and Dispose Sludge? Waste Management

The dosage of ferric chloride and alum for elutriated digested sludge are of the order of 1.0 kg/m 3 of sludge. Alum when vigorously mixed with the sludge, reacts with the carbonate salts and release CO 2 which causes the sludge to separate and water drains out more easily. Hence for effective results, alum must be mixed quickly and thoroughly.

CHAPTER 4 DESCRIPTION OF THE FACILITY GENERATING

The conditions under which sludge is stored can impact both its dewatering capability and its chemical quality as a soil conditioner. For example, some facilities aerate stored sludge, while others employ gravity thickeners that double as storage tanks. In some cases, thickeners e.g., flotation thickeners are used prior to storage and dewatering.
