Abstract
A treatment system for removal of contaminates includes the introduction of a flocking agent and the settling of resultant aggregations of particulate material, followed by filtration of the remaining water to remove residual flocking agent and particulate matter. Water thus treated is sufficiently clean to discharge into downstream receiving waters, in an effective and efficient manner, and is sufficiently free of flocking agent to avoid being a hazard to aquatic life. The required dose is activated by a rain gauge which meters rainfall over an appropriate time period and evaluated by the microprocessor.
