Can aluminum sulfate control phosphorus in stormwater runoff? 

Yes, HAB’s On-Shore Treatment System is used to control external sources of phosphorus (for example, storm water entering a lake from a ditch or culvert). With this approach, the chemical formulation is precicely injected into the external water source and binds the phosphorus to the floc before it enters the lake, thus rendering the phosphorus unavailable for algal growth.
