Abstract: The relative importance of three different Al species, Al-a (monomeric species, instantaneous reacted species), Al-b (medium polymer species, reacted less than 120 min), and Al-c (colloidal or solid species, no reaction), defined by timed complexation reaction rate measured by using ferron reagent in polyaluminum chloride (PACl) was investigated in terms of DOC (dissolved organic carbon), UV254, and turbidity removal efficiencies. Micro-polluted, typical North China, source waters were used to conduct the experiments. The results show that DOC removal is correlated well to the content of Al-b. Removal of UV254 is determined by the content of Al-b and Al-c, particularly Al-c. Turbidity removal is primarily related to the content of Al-c; however, Al-b could destabilize particles efficiently, and the flocs formed by Al-b axe not as large as those formed by Al-c, which affected the settling efficiency. Unlike the preformed Al-b, the in situ formed Al-b could remove turbidity more efficiently since Al-c is the dominant final species formed during coagulation. Al-a shows a strong ability to react with some unsatisfied coordinate bonds of organic matter to facilitate particle and DOC removal. The distinct coagulation feature of Al-a, Al-b, and Al-c can be applied to develop tailor-made PACl (with the correct distribution of Al species) to match the characteristics of raw water for optimized coagulation.

Abstract: Water samples collected from early March 2001 to the end of April 2002 at the branch of Pearl River around the Guangzhou City were analyzed for its micro-polluted characteristics. The coagulation behavior of polyaluminum chlorides (PACIs) was then examined focusing on the effect of primary water quality and speciation distribution. The results showed that PACIs exhibit better coagulation efficiency than alum in accordance with the different speciation. The turbidity removal property of PACIs is evidently better than alum at low dosage. While in neutral zone(about 6.5-7.5), the turbidity removal of PACIs decreases owing to the restabilization of particles at higher dosage. The organic matters in raw water exhibit marked influence on coagulation. In acidic zone, organic matters complex with polymer species and promote the formation of flocs. With an increase in pH, the complexation of organics with polymer. species gradually decreases, and the removal of organics mainly depends on adsorption. The effect is evidently improved with the raise of B value.

Abstract: The biofiltration has good performance in micro-polluted source water treatment, and the removal rate of the TOC, DOC and AOC are 23.30%, 1.9.13%, and 83.86%, respectively. The removal rates of organic pollutant with small molecular weight(<1 000) and with molecular weight of 3 000 - 6 000 are 54.46% and 54.57% respectively, and the removal rate of the organic pollutant with molecular weight of 1000 - 3 000 is only 11.37%. These organic pollutants mainly consist of synthetical compound(keto compound, hydroxybenzene and phenyl acid ester) and humic acid.
