In the Mosquito Lagoon located in New Smyrna Beach, Florida, stormwater runoff was discharged without any treatment, and this runoff, containing suspended material, has caused a 4-5 ft accumulation of muck. Coagulation was proposed as a treatment method for the runoff in a partially hydraulically isolated basin from the lagoon. In addition, recycle of saline water from the lagoon upstream of the storm sewer outfall to act as a settling aid in the basin was proposed. Laboratory experiments were conducted to determine the effectiveness of the use of two known coagulants, alum (Al2(SO4)3·18H2O) and ferric chloride (FeCl3·6H2O). The removal efficiencies obtained by the coagulants were compared with the effect of salinity on suspended solids (TSS) removal. The results of the study were that alum was the best coagulant for the stormwater runoff composition while salinity could not be shown to be an effective settling rate enhancer.
