The Analysis and Improvement Measure of Chemical Stability of Water Quality in Jinan City Water Distribution System

Abstract:

The water quality chemical stability of Jinan's three waterworks (Quehua, Yuqing and Nanjiao waterworks) was analyzed through determination of several parameters affecting the chemical stability of water quality, including temperature, pH, Ca content, alkalinity, total hardness, total dissolved solids, chlorides, sulfates. For comprehensive and objective evaluation of the chemical stability of water, four water stability indexes LSI, RSI, AI, LR were used in this paper. The resulted index values indicated the corrosion in Jinan water distribution system may occur, and different source waters have different chemical characteristics. Yellow river water (Yuqing and Quehua) is high in chlorides and sulfates, while Nanjiao water is low in chlorides and sulfates. The improvement measure to chemical stability of water quality in Jinan City water distribution system included adding alkalinity, and blending water from different waters to reduce LR. The research proposed a way to control red water problem, which is meaningful to protect pipe works and improve tap water quality.
