Laboratory investigations into the use of magnesium carbonate instead of alum for coagulation have demonstrated that the magnesium carbonate system produces a treated water with superior characteristics compared to water treated with alum. Both turbidity and organic color removals were comparable for both processes, and the flocs formed by the magnesium carbonate process were larger and heavier than alum flocs with better settling characteristics. The process involves the use of the magnesium carbonate as a coagulant and lime is added to precipitate gelatinous Mg(OH)2. The sludge, composed of a slurry of Mg(OH)2, CaCO3, and clay is carbonated and the Mg(OH)2 selectively and completely dissolved. Recycle after filtering allows re-use of both the magnesium carbonate and the sludge water. CaCO3 can also be recovered easily in large plants or landfilled at small ones. Chemical treatment costs for most waters can be substantially reduced using this system, while the quality of treated water will be superior to the quality of alum-treated water.
