Achieving Effective Algae Removal Prior to Filtration: Comparison of Conventional Treatment and Microsand-Enhanced Flocculation 过滤前实现有效的藻类去除:常规处理与微絮凝和强化絮凝的比较
发布日期: 1999-01-01
本研究的目的是:研究常规处理中影响藻类去除的因素;并比较了常规处理与微絮凝强化絮凝(MEF)处理的除藻效果。常规混凝实验旨在比较明矾和硫酸铁在以下条件下对藻类的去除效果:相同的流动电流值;以及等摩尔金属离子添加剂。此外,还进行了jar试验,以评估混凝pH值和阴离子助凝剂剂量的影响。在pH值为6的条件下,将常规混凝和MEF与明矾和硫酸铁进行比较,其剂量可导致电荷滴定测定的电荷中和。 包括14个参考文献、表格和图表。
The objectives of this work were to: study factors that affect algae removal in conventional treatment; and compare the algae removal effectiveness of conventional treatment with that of microsand-enhanced flocculation (MEF). Conventional coagulation experiments were designed to compare algae removal with alum and ferric sulfate at the following conditions: equal streaming current values; and equimolar metal ion additions. Furthermore, jar tests were conducted to evaluate the effects of coagulation pH and anionic flocculant aid dose. Algae removal was compared for conventional coagulation and MEF at pH 6 with alum and ferric sulfate at doses that led to charge neutralization as determined by charge titrations. Includes 14 references, tables, figures.
