Background: Internal corrosion and the formation of scale in water distribution pipes are the most important problems for an urban water distribution system. Physical, chemical, or biological factors can lead to these two processes. Internal corrosion and scale formation can impact health, economy, and aesthetics. This study assessed the physicochemical quality parameters and evaluated the pote...

The results of a metallographic study of grey cast iron water pipes are reported. These pipes had been installed between 1885 and 1973 in eight different water systems. Each pipe had been extracted during scheduled maintenance or failure repairs to provide data for a larger study to produce a methodology for determining the residual life of grey cast iron pipes. This metallographic study was co...

background & aims of the study: corrosion and scaling play undesirable effects on transmission and distribution system of drinking water. the aim of this study was to assess the corrosion and scaling potential of drinking water resources in babol city, iran. materials and methods: totally, 54 water samples were collected from 27 wells in spring and autumn. calcium hardness, ph, total alkalinity...

Corrosion is a physicochemical reaction occurring between the metal and its surroundings, which usually has an electrochemical nature and results in changes in the properties of the metal. The corrosive water dissolves the pipe’s material during flowing and this causes many problems. This study investigated the potential of corrosion and scaling of 46 water supply resources in the villages of S...

Hexametaphosphate tends to increase release of both particulate and soluble lead to drinking water. For every mg/L of residual hexametaphosphate, soluble lead increased by 1.6 – 2.5 mg/L after 72 hour stagnation in pure lead pipes compared to the same condition dosed with orthophosphate. Utilities should consider these adverse effects whenever polyphosphate is used to prevent scaling or iron pr...

Introduction: Corrosion and scaling are important factors affecting drinking water quality, causing health and economic problems. This study aimed to investigate the indicators of corrosion and scaling in Rafsanjan drinking water. Materials and Methods: The present descriptive cross-sectional study was conducted in winter 2018 and spring 2019 in Rafsanjan. The 56 samples were randomly taken fr...

Environmental protection agencies strictly regulate the presence of PAHs in air, water, soil, industrial, and food because this group of chemicals varies in structure and toxicity. The analysis of drinking water for the presence of PAHs is important as coal tar is normally used to protect distribution pipes from corrosion and therefore can be considered the main source of PAHs in drinking water...
