Background and Objective: Water corrosion and scaling are known as destructive phenomenon of drinking water quality and water facilities. In this study, the groundwater tendency to corrosion or scaling in source water, water storage reservoirs and distribution system were studied. Simultaneous use of some qualitative and a quantitative index along with statistical analyses to assess the water s...
Background : Occurrence of corrosion and deposition in drinking water in distribution system can leads to economic and health damages. The aim of this study was to investigate the corrosion and precipitation potential of drinking water in Kerman distribution system. Methods : This cross-sectional study was performed from September to November of 2011. For determining the chemical quality of...
BACKGROUND This paper discusses the corrosion and scaling potential of Tabriz drinking water distribution system in Northwest of Iran. Internal corrosion of piping is a serious problem in drinking water industry. Corrosive water can cause intrusion of heavy metals especially lead in to water, therefore effecting public health. The aim of this study was to determine corrosion and scaling potenti...
Introduction: Scaling and corrosion is one the most important indices in water quality evaluation. Occurrence of scaling or corrosion may create disorder in economy of water and wastewater industry. In addition, corrosion produces by - products in water leading to health problem and reduction of water pipe life-time. In this study, the condition of scaling and corrosion in Bandar Abbas wa...
Background & Aims of the Study: Corrosion and scaling are the most common problems of water facilities. Corrosion imposes many financial and health loss on system and consumer respectively, scaling also causes clogging and head loss in network. The purpose of this study is to determine the corrosion and scaling potential of water supply sources of Qom villages. Materials &...
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. materials and methods: totally, 54 water samples were collected from 27 wells in spring and autumn. calciu m hardness, ph, total alkalinity, tot...
Background & Aim: Corrosion is one of the most complicated and costly problems related to the drinking water supply that can influence the health of consumers, the general acceptance of a water resource, and the costs of water supply. Scaling also causes problems such as clogging and head loss in drinking water networks. The aim of this study was to determine the chemical quality and stability ...
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...
