This process is a true reduction of total dissolved solids (TDS) in that all chemicals added for treatment are precipitated during the reactions. Operating costs for near-complete sulfate removal using the process, which has been demonstrated successfully for many industrial waters, are estimated at $3 to $6 per 1000 gallons treated.
aluminum sulfate. Aluminum sulfate will further lower the water pH and alkalinity creating ad-ditional problems. A good water test is needed prior to any treatment process. If the pH is below 7.0, and the alkalinity is below 50 ppm, limestone is likely the best choice. However, if alumi-

Mar 07, 2011· History : With Aluminum Sulfate, Sodium Hydroxide can be used to precipitate transition metal hydroxides. Aluminum Hydroxide is used as a gel floccilant to filter out particulate matter in water treatment. Aluminum Hydroxide is prepared at the treatment plant from Aluminum Suldate by reacting it with Sodium Hydroxide.
Jul 06, 1988· Aluminium sulphate is added to water as a flocculent during the purification process in order to precipitate organic matter. The quantity of aluminium required for this process varies with environmental factors, so the concentration in tap water may range from 5–30 μmol/L.
The aluminium production process can be broken down into three stages; first bauxites, which contain aluminium, are extracted from the ground. Second, bauxites are processed into alumina or aluminium oxide, and finally in stage three, pure aluminium is produced using electrolytic reduction, a process in which aluminium oxide is broken down into ...
