System and Method for Removing Phosphorus From Non-Point Pollution Sources

摘要

A modularized phosphorous filter (P-filter) for installing into open flow channels, such as urban and rural drainage ditches, streams, rivers, bayous, swales, etc. In some embodiments, the P-filter includes a module formed from a container that contains a phosphorous-filtering mass of loose pieces of slag. The container has anchoring extensions for anchoring the P-filter into the sides of the channel into which it is installed. In other embodiments, the P-filter is made of a number of P-filter modules each including a container that contains a phosphorous-filtering mass of loose pieces of slag. The P-filter modules are stacked with, and/or otherwise arranged relative to, one another so as to form a modularized P-filter. Preferably, the P-filter modules are sized to be readily movable by one or more people and/or power equipment, such as a tractor having a backhoe.
