Drinking water treatment residuals: a review of recent uses.

Coagulants such as alum [Al2(SO4)3 x 14H2O], FeCl3, or Fe2(SO4)3 are commonly used to remove particulate and dissolved constituents from water supplies in the production of drinking water. The resulting waste product, called water-treatment residuals (WTR), contains precipitated Al and Fe oxyhydroxides, resulting in a strong affinity for anionic species. Recent research has focused on using WTR...

Removal of inorganic As5+ from a small drinking water system

The drinking water from a small drinking water system contained arsenic in a concentration of about 50 μg/L. Chemical analyses showed that the pentavalent form of arsenic was present. Since the MCL value is 10 μg/L, it was necessary to implement a technological treatment to make the water suitable for drinking. In order to do so, two technologies were suggested: activated alumina and α-FeOOH (T...

The Study of Coagulation Process in Medium Turbidity Removal from Drinking Water Using Various Inorganic Coagulants: A Comparative Study

Background and aims:  Colloidal impurities are one of the natural contaminants in surface water that cause turbidity and color. Turbidity in spite of create undesirable appearance, can be a haven for disinfection of microorganisms. This study aimed to evaluate the effectiveness of various coagulants in removing average turbidity of water and also their impact on the electrical conductivity and ...
