A zeolite filter pilot plant was operated over a 216 day period to evaluate its ability to enhance nitrogen removal from stormwater. When operated at a steady filtration rate of 192 gal/ft2 -day, the zeolite filter was highly effective at removing ammonia, producing an effluent ammonia nitrogen concentration of 0.07 mg/L, and removing 93% of ammonia and 32% of total inorganic nitrogen. A variety of non-steady state experiments demonstrated that the zeolite filter performance was superior to a parallel sand filter under the varying conditions that are common to stormwater management systems. A storm event was simulated by applying a …

Irrigation of detained stormwater is an option available for volume and pollution control. Volume control is accomplished when detained waters normally discharged from a detention facility are used instead for irrigation. However, a health risk may result if the nitrate in the irrigation water is not attenuated in the plant and soil matrix. The nitrate level in stormwater ponds is generally much less that the health risk specified as 10 mg/L in Drinking water standards. Nevertheless, the fate of nitrate in the soil plant matrix has not been documented. In addition, there are other potential problems associated with not maintaining …

Algal blooms are a common occurrence in water bodies of all shapes and sizes in the State of Florida as well as all other locations around the world. Cyanobacteria, or blue-green algae, have proven to be of special concern due to proliferation and potential to produce toxins that are harmful to humans, livestock and wildlife. Casual observations of lakes and stormwater ponds in Florida will confirm algal conditions in many. The health risks and the potential for exposure to harmful and possibly fatal toxins associated with these algal blooms are becoming more evident as more nutrients are discharged to our …
