Systematic Studies Regarding the Introduction of a New Product in the Flow of Drinking Water of an Atypical Surface Source

Abstract

Polyaluminium chloride is a new coagulation reagent recommended for water treatment. This paper presents a study regarding water treatment from the storage lake St�mtori � Firiza with this new coagulation reagent in comparison with the classic method currently applied. The classic method uses cake of alum (aluminium sulfate) and hydrated lime. In the case of atypical waters having low temperatures, low alkalinity and variable turbidity, the classic method has poor results. The main purpose of the experimental studies is to establish the adequate doses of coagulation reagent for obtaining drinking water according to present legislations.
