该报告比较了整个过滤循环中化学/物理和生物除铁过程的效率。Tom’s River Water公司进行的一项试点研究结果表明,生物除铁将在至少8.0 gpm/sq.ft.的流速下,将地下水中的铁浓度降低到0.05 mg/L以下。高速过滤可降低资本成本,减少空间需求。
The report compares the efficiency of chemical/physical and biological iron removal processes during the entire filter cycle. The results of a pilot study performed for the Tom's River Water Company indicate that biological iron removal will reduce the iron concentration of groundwater to less than 0.05 mg/L at flow rates of at least 8.0 gpm/sq. ft. The high rate filtration, allows for lower capital costs, and less space requirements.
