Sorbents for phosphate removal from agricultural drainage water

Subsurface transport of phosphate (P) from fertilized agricultural fields to freshwaters may lead to eutrophication and reduced biodiversity in inland waters. Mitigation of eutrophic waters is difficult and costly. Reduction of P export to surface waters using filters installed in agricultural drains comprising P sorbing materials (PSM) may be a more efficient and cost-effective way to improve water quality. Several materials have been proposed as PSMs for use for cleaning agricultural drainage water.

The objective of the present study was to provide data on sorption behavior among a variety of PSMs in order to select a material that can quickly remove P from runoff water at both base and peak flow.
