CRD Sludge Treatment Plant PROCESS: 1. Sludge will be piped to the site 2. Removal of Fats, Oils & Grease (FOG) 3. Anaerobic digester will produce gases 4. Gases will be processed to produce methane 5. Methane will be supplied to the local natural gas lines 6. Other gases will be processed/flared? 7. Biosolids will be dewatered & dried TRUCKING: 1. Dried bio-‐solids 2. Struvite (phosphorous/ferDlizer) 3. FOG (Fats, Oils & Grease)
