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...
a methodology is presented in this paper to find optimal location and dosage of chlorine injection in water distribution networks. the objective is to minimize the chlorine consumption while keeping the residual chlorine at each node within the standard range. unfortunately because of wrong water quality management in water distribution networks in many parts of the world, many problems such...
Background and Objective: one of the steps in water treatment to protect microbial quality of water network is disinfection. Chlorine is one of disinfectants. It is necessary to maintain Free Residual Chlorine (FRC) between minimum and maximum throughout the distribution system in accordance to health standards. This study was aimed to optimize Chlorine dosage in water distribution networks usi...
background: the dispersed phase volume fraction plays key role in oil-in-water emulsion stability by different mechanisms like partial flocculation, depletion flocculation and bridging flocculation. since the mentioned mechanism is affected by emulsifier concentration presented in system, the major aim of this study was to investigate the effect of dispersed phase volume fraction on physical st...
تجزیه و تحلیل عدم اطمینان برای هر پدیده منظره ای واقعی از پارامترهای آن را نمایان می کند و درک درستی از عوامل تأثیرگذار بر آن پدیده را ایجاد می کند. منظور از تجزیه و تحلیل عدم اطمینان، تشخیص خواص آماری مدل خروجی بر اساس روابط موجود بین پارامترهای آماری ورودی می باشد. بررسی عدم قطعیت و چگونگی تأثیر پارامترهای مختلف در کارایی شبکه های توزیع آب از مباحث مهم در تحلیل ریسک و اطمینان پذیری در طراحی...
Water is the most essential component for sustaining lives of humans and other living creatures. Supplying potable water with adequate residual pressure is a fundamental responsibility of city administration, which they do during normal conditions. But sometimes, abnormal conditions are formed resulting pressure deficient conditions during the daily operations of water distribution networks. Th...
