What is alum sulphate used for?
Aluminium sulphate (Al2 (SO4)3) is a chemical compound that is soluble in water. The compound is mainly used as a coagulant during the water purification process, wastewater treatment, and paper manufacturing.
What is alum used for in water treatment?
Alum is a natural coagulator, astringent and antiseptic. Due to the coagulation property, it is used in the filtration process of raw water. In the water treatment process, Alum reacts with the impurities in water and forms an aggregate to settle out of the water or be easily trapped by a filter.
How much alum do I add to my pond?
Ohio recommends 25 to 50 pounds of alum per acre-foot. An initial treatment 25 pounds per acre-foot should clear the water in a few hours. If there is no change after one day, add another 25 pounds per foot acre.

Are there any health concerns with buffered alum?

Indeed, there has been only one reported case in the United States in recent years where toxicity has been a problem. Human health concerns are largely avoided simply because people do not drink untreated lake water.
What is the pH of buffered alum in water?
Free aluminum may persist at pH less than 6 or other hydroxides may form at pH greater than 9; although toxicity may occur at pH > 8 in some conditions. Both forms may be toxic to aquatic life. As a practical matter, the use of buffered alum has mitigated this concern by controlling the pH to acceptable ranges.
How is alum used in the water treatment process?
However, the water treatment process at many, if not most, water utilities uses alum as a clarifier before filtration anyway. Again, the raw water supply does not exceed drinking water standards shortly after an alum application.
Can you use alum in soft water lakes?
The treatment of lakes with alkalinities above 75 mg/L as CaCO3are not expected to have chronic or acute effects to biota. Fish related problems associated with alum treatments have been primarily documented in soft water lakes. However, many softwater lakes have been successfully treated with alum, when the treatments are ph buffered.
