Typical surge analysis of long distance pipelines involve pump power failure and startup at lift stations discharging into force mains. Utilities have several options for protecting pipeline systems from the effects of transients and surges. But how to select an effective surge protection strategy to design the system to withstand the stresses of transients is still a great challenge, especially for...
Lack of safe drinking water is a major problem in rural areas, it also persists in places like irrigation districts. this study was carried out to establish the accessibility of water in rural areas of Jinghuiqu Irrigation District(JHQID). In these areas, main sources of water for domestic purposes were groundwater and the piped water coverage rate was low, only 1,204,500 residents got their drinking...
Chlorination of drinking water leads to the formation of trihalomethanes (THMs) that has been proved have adverse health effects on humans. Research on this subject has been continued and new epidemiological and toxicological studies have been conducted. In this paper, authors investigate and analyze factors affecting THMs formation in pipe networks by conducting corresponding experiments on a close...
In practical engineering, water supply systems often work in variable working condition and their energy Consumption depends largely on the adjustment methods. Through the experiments, pumps in parallel were operated by many kinds of regulate methods in varied flow or in variable frequency, the Q-?? graphs in different schemes were obtained and energy saving effects of the systems variable frequency...
In the past decade, evolutionary methods have been used by various researchers to tackle optimal design problems for water supply systems (WSS). In this paper, a optimal operation model with multi-objective mixed discrete variables is established for large-scale water supply systems of some city, and the model is solved by using particle swarm optimization (PSO). Simulation results of the water supply...
In order to observe and gather viewpoints from various technological achievements undertaken in the frameworks of water distribution systems, a state-of-the-art is researched and presented here in form of methodological highlights related to these fields. Furthermore, to be established and guarantee the thorough efficiency of water supply systems, a method relying on pattern recognition approaches...
