Innovative Technologies for Phosphorus Reduction From Non Point Pollution Sources.

PhosphoReduc^™ Filter systems for P removal from both point and nonpoint pollution (NPP) sources have been developed as a result of over 10 years of research and testing on over 70 different adsorbing materials in numerous laboratory, and pilot and demonstration projects. PhosphoReduc^™ Filter systems for P removal from NPP sources was developed in 2006,  as a simple, passive system consisting of one or more filter units placed in drainage pathways either in agricultural or urban landscapes. Since 2006, the performance of the systems has been tested on several locations in the USA and Canada. The results showed evidence on the efficacy of PhosphoReduc^™ filter systems in reducing P from both high and low effluent concentrations and a variety of pollutant loadings. In addition, the systems have minimal land area and no energy requirements, minimal operation and maintenance costs and simple installation and as such are cost efficient and beneficial to the environment.
