Evaluation of Microflocculation Due to Prezonation

该奖项是为资金支持的研究调查的一个 机理基础，并建立了微絮凝模型 在水中应用臭氧作为预氧化剂时观察到 治疗实践。 该研究将解决微絮凝， 预臭氧化对有色、低碱度、低浊度源的去除率高 沃茨。 将研究四种机制的影响。这些 是（a）腐殖物质颗粒尺寸分布的重排 导致更有效的凝聚和絮凝，（B） 腐殖酸臭氧化降解产物通过氢气的重组 结合，（c）氧化和分离与腐殖酸络合的金属 材料及其随后作为凝结剂的作用，和（d）组合 溶解的本体溶液金属与络合金属， 凝结剂或甚至沉淀。 主要研究者具有执行拟定研究的高资质 research. 建议提供两年连续补助金。 这个奖项是 第一年76,100美元

This award is for funds to support research on the investigation of a mechanistic basis and to develop a model for the microflocculation observed with the application of ozone as a preoxidant in water treatment practice. The research will address microflocculation due to preozonation highly on colored, low alkalinity, low turbidity source waters. The influence of four mechanisms will be investigated. These are (a) rearrangement of humic material particle size distributions leading to more efficient coagulation and flocculation, (b) recombination of humic ozonization degradation products via hydrogen bonding, (c) oxidation and separation of metals complexed with humic material and their subsequent action as coagulants, and (d) combination of dissolved bulk solution metals with complexed metals to act as coagulants or even to precipitate. The principal investigator is highly qualified to perform the proposed research. A two year continuing grant is recommended. This award is for $76,100 for the first year.
