All Sodium Aluminate solutions are produced according to EN 882 (Chemicals used for the treatment of water intended for human consumption). Aluminum products reduce chemical sludge production compared to iron, due to the low molecular weight of AI. Aluminates raise the alkalinity of the water, eliminating the need for lime or hydroxides.

upon the raw water source, the type and degree of treatment, and the method of sludge removal from the sedimentation basins. A large per-centage of the chemical constituents were adsorbed to the sludge solids leaving a relatively clean filtrate and decant to be disposed. For the drying period of interest in sludge drying, the major

Use of sludge in cement kilns can also tackle the problem of safe and eco-friendly disposal of sewage sludge. The cement industry accounts for almost 5 percent of anthropogenic CO 2 emissions worldwide. Treating municipal wastes in cement kilns can reduce industry's reliance on fossil fuels and decrease greenhouse gas emissions.

One of the most widely used methods for sludge treatment. Sludge is held in the absence of air for 15 to 60 days at temperatures of 68 to 131°F. Anaerobic bacteria feed on the sludge, producing methane and carbon dioxide. In some treatment plants, the methane is collected and burned to maintain the treatment temperature.
