Abstract

Dorea's commentary on our paper (Curry et al. 2020), on how a common alum pretreatment technique reduces turbidities of biosand filter (BSF) source water but still results in significantly lower flow rates, is extremely helpful and gives further insight into why the flow rates decreased. The explanations and additional resources cited by Dorea in the commentary help explain why the flow reductions observed from alum pretreatment can vary depending on the type of source water.
