Abstract In 1976, the US Environmental Protection Agency (USEPA) published the results of
a national survey that showed that chloroform and other trihalomethanes (THMs) were …

A mass-transfer-based model is developed for predicting chlorine decay in drinking-water
distribution networks. The model considers first-order reactions of chlorine to occur both in …

Models of chlorine kinetics in distribution systems characterize chlorine decay as a
combination of first‐order decay in the bulk liquid and first‐order or zero‐order decay …

A methodology for finding the optimal layout of a detection system in a municipal water
network is formulated and demonstrated. The detection system considered consists of a set …

Hydraulic water distribution system (WDS) simulation models are widely used by planners,
water utility personnel, consultants and many others involved in analysis, design, operation …

Free chlorine decay rates in water distribution systems for bulk and wall demands should be
modelled separately as they have different functional dependencies. Few good quality …

A model that accounts for transport in the axial direction by convection and in the radial
direction by diffusion and that incorporates first order decay kinetics has been developed to …

Fixed biomass (biofilms) chlorine demand, produced from 3 test waters, is studied by the
means of two methods: directly on colonized plastic beads and indirectly on biomass …

Passage of the Safe Drinking Water Act in 1974 and its Amendments in 1986 (SDWAA) is
changing the way water is treated and delivered in the United States. Under the SDWAA the …
