A new conceptual model to describe and understand the role of assimilable organic carbon (AOC) within drinking water distribution systems is proposed. The impact AOC on both biofilm quality was studied using bespoke pipe loop experimental facilities installed at three carefully selected operational treatment works. Integrated physical, chemical biological monitoring undertaken that highlights c...

The present study encompasses a new method to simultaneous analysis, design and optimization of Water Distribution Systems (WDSs). In this method, analysis procedure is carried out using Charged System Search (CSS) optimization algorithm. Besides design and cost optimization of WDSs are performed simultaneous with analysis process using a new objective function in order to satisfying the analys...

unsustainable harvesting of agricultural water resources in the province of kerman, has caused an annual average of one-meter drop in ground water levels. surface irrigation methods in pistachio trees have low efficiency because of inherent characteristics and its incorrect application, as well as low access to water resource in pistachio regions. therefore under the current critical condition,...

OBJECTIVE To compare levels of water fluoridation in urban and rural distribution systems in Ontario. METHODS A random sample of 17 urban and 17 rural municipalities was taken from a list of 445 municipalities. The Ontario Ministry of the Environment (MOE) website was used to identify the water treatment plants that supply these municipalities, and water quality reports published by each of t...
