【 摘 要 】

The effect of pipe fittings (mainly T-pieces) on particle accumulation indrinking water distribution networks were shown in this work. The onlinemeasurements of flow and turbidity for cast iron, polyethylene andpolyvinyl chloride pipe sections were linked with analysis of pipe geometry.Up to 0.29 kg of the total amount mobilized in T-pieces ranging from DN100/100–DN 250/250. The accumulated amount of particles in fittings wasdefined as J and introduced into the existing turbidity model PODDS(prediction of discoloration in distribution systems) proposed by Boxall etal. (2001) which describes the erosion of particles leading to discolorationevents in drinking water network viz sections of straight pipes. However, this work does notinterpret mobilization of particles in pipe fittings which havebeen considered in this article. T-pieces were the object of this study anddepending of the diameter or daily flow velocity, the coefficient J variedfrom 1.16 to 8.02. The study showed that pipe fittings act as catchmentareas for particle accumulation in drinking water networks.
