Modeling of residual chlorine in water distribution system

Water quality within water distribution system may vary with both location and time.Water quality models are used to predict the spatial and temporal variation of water quality throughout water system.A model of residual chlorine decay in water pipe has been developed, given the consumption of chlorine in reactions with chemicals in bulk water,bio-films on pipe wall, in corrosion process, and the mass transport of chlorine from bulk water to pipe wall.Analytical methods of the flow path from water sources to the observed point and the water age of every observed node were proposed .Model is used to predict the decay of residual chlorine in an actual distribution system.Good agreement between calculated and measured values was obtained.

Cultivation and characters of aerobic granules for pentachlorophenol (PCP) degradation under microaerobic condition

Cultivation of aerobic granular sludge for pentachlorophenol (PCP) degradation under microaerobic condition (DO concentration was controlled at 0.2-0.7 mg/L) was studied in this paper. Anaerobic granules were selected as inoculum. The changes of appearance were observed and the variations of SVI, VSS/TSS, PN/PS and the size of sludge were measured during cultivating. The capabilities for degradation of PCP, AOX and CODcr were also studied. Observations on mature granules were carried out by scanning electron microscope, and the results indicated bacillus was dominant on the surface of granules while in the inner of granules both bacillus and coccus were the dominant microorganisms. K, Na, Fe, Ca, Mg, Ni, Co, Mn, Cu and Zn were detected in the granules by element analysis.
