Aerobic lake muds for the removal of phosphorus from lake waters1

TLDR: In this paper, the rate of sorption of phosphorus by lake muds, under aerobic conditions, from two lakes and from three depths in one lake, indicated that as little as 0.4 g (dry wt) of mud could sorb about 0.05 mg Pod-P in less than 30 min.

Abstract: Phosphorus-limited Selenastrum and CZado$zoru sp. will respond by growth or changes in extractable POa-P to as little as 0.02 mg POC-P in solution; these same spccics did not respond when exposed for a period of 1 or 2 weeks to as much as 2 mg of phosphorus as lake muds under aerobic conditions. Studies of the rate of sorption of phosphorus by lake muds, under aerobic conditions, from two lakes and from three depths in one lake, indicated that as little as 0.4 g (dry wt) of mud could sorb about 0.05 mg Pod-P in less than 30 min. These findings suggest that the sorption of phosphorus by lake muds under aerobic conditions can be used to remove phosphorus from lake water.
