Loose deposits (LD) accumulate in drinking water distribution systems (DWDS) and may lead to tap water discoloration incidents upon resuspension. While inconvenient for the consumers and the water companies, discoloration may be accompanied by degradation of the microbiological quality of the water, and possibly to the transport of bacteria. The presence of heterotrophic bacteria towards LD with different characteristics was investigated. Bacterial loads in discoloured water samples and LD concentrated over different settling times were analysed. Total heterotrophic (TH) bacteria numbers did not relate to turbidity or to suspended solids in discoloured waters. Higher affinities of TH were observed for slower-settling LD (

Optimization of Submerged Ceramic Micromembrane Filtration for Surface Water Treatment

REMOVED: Practical Experience of Backwashing with RO Permeate for Fouling Control of UF Treating Surface Water

. Primary goal of a drinking water company is to produce safe drinking water fulfilling the quality standards defined by national and international guidelines. To ensure the produced drinking water meets the quality standards, sampling of the drinking water is carried out on a regular (almost daily) basis. It is the dilemma that the operator wishes to have a high probability of detecting a bias while minimizing his measuring effort. In this paper a seven step design methodology is described on how to come to an optimized water quality monitoring scheme. It was shown that the existing on-line monitoring program of a WTP could be optimized. Besides using soft-sensors as surrogate sensors for parameters currently not available on-line, they can also provide a cost effective alternative when used to determine multiple parameters required through one single instrument.
