Corroded scale analysis from water distribution pipes

An Intelligent System to Classify Leaks in Water Distribution Pipes

in water distribution network are generally detected and located using conventional methods that is not able to give previously any idea about leak size. Current paper draw proposal plan to discriminate leaks according to its size, using a modular system in four blocs: 1) Signal preprocessing, 2) Representation using modified Mexican hat wavelet 3) Dimensionality reduction using random projecti...

Sensitivity analysis to assess the relative importance of pipes in water distribution networks

Water distribution networks are not randomly constituted systems. On the contrary, their designs are closely related to their hydraulic performance. Recognizing the sundry and relative importance of the different pipes in a water distribution network may help in assessing their impact on the hydraulic performance of the network. This information, in turn, will be helpful in the different aspect...

Effect of sulfate on the transformation of corrosion scale composition and bacterial community in cast iron water distribution pipes.

The chemical stability of iron corrosion scales and the microbial community of biofilm in drinking water distribution system (DWDS) can have great impact on the iron corrosion and corrosion product release, which may result in "red water" issues, particularly under the situation of source water switch. In this work, experimental pipe loops were set up to investigate the effect of sulfate on the...

Color-rendering of Daylight from Water-filled Light Pipes

Water-filled light pipes can be used to transport concentrated beam solar radiation from a solar collection system to a utilization system, altering the spectral distribution of the radiation in a beneficial way in the process. One use for such a system would be for the daylighting of the core interior spaces of buildings, spaces that are far removed from outside walls or the roof and are there...
