PAC Testing Results ‣ Dosing PAC together with alum results in significantly lower MIB removal (28% removal Alum/PAC vs 55% PAC then alum) ‣ PAC should be added prior to alum ‣ Optimum/Minimum PAC detention time is 45 minutes ‣ Min./Max. PAC dosage is 30 mg/L - 60 mg/L
Plant Impacts of Testing ‣ 45 Minutes of Detention Time at 15 MGD requires at 500,000 gallon pre-carbon contact tank with mixers ‣ 30 mg/L dosage results in an additional 3,800 ppd of Dry Solids ‣ This would double the plant solids production and require additional residuals treatment equipment ‣ Dispose of residuals in Quarry
