涉及低化学剂量和高过滤率的直接过滤可以通过降低资本成本、减少空间需求、减少污泥量和潜在的混凝剂剂量来降低处理某些水源的成本。本文回顾了直接过滤的实验室规模、中试和工厂试验的现场经验。包括20个参考文献和表格。

Direct filtration that involves low chemical dosages and high filtration rates can reduce the cost of treating certain water sources through lower capital costs, reduced space requirements, decreased sludge quantities, and potential reductions in coagulant dosages. This article reviews field experience with bench-scale, pilot, and plant tests of direct filtration. Includes 20 references, tables.
