Review of biological stability and corrosion potential in drinking water distribution system

Abstract

In this paper, the corrosive properties of the water treatment plants system and biological stability were clarified. Several
studies and dissertations published in this subject were reviewed in this paper. The problem of corrosion was explained and
the reasons for their occurrence, Methods are used to reduce this characteristic, water stability and the factors affecting
corrosion, Stability and correlations, which included five indicators: Langelier Saturation Index (LSI) ,Ryznar Stability
Index (RSI), Puckorius Scaling Index (PI, Larson–Skold Index (LS), Aggressive Index (AI)
