Evaluation of the GAC Treatment Facility at the Lake Angel Detention Pond, Orange County, Florida
Two Granulated Active Carbon (GAC) beds of Filtrasorb 400 in series were used to reduce the Trihalomethane Formation Potential (THMFP) concentrations at the Lake Angel detention pond, Orange County, Florida. Color and TOC were considered acceptable surrogate parameters of THMFP at the GAC detention facility. THMFP and TOC concentrations had a correlation coefficient of 84 percent while those between THMFP and color and TOC and color were both 89 percent. Breakthrough occurred in the first bed after treating 138,000 liters of water. Exhaustion of the first bed was reached after treating 185,000 liters of water. The liquid flow rate averaged 0.0011 cfs. Similar breakthrough curves for Total Organic Carbon (TOC) and color were also reported. Resistance to flow from the GAC resulted in long empty bed contact times (EBCT). Tracer studies indicated that EBCT was not an accurate indicator of the time the adsorbate was in contact with the carbon.
