Recycle Plant Process Collection Bio Process Coagulate Flocculation Sedimentation Filter Disinfect Storage

Recycle Plant Process Collection Bio Process Coagulate Flocculation Sedimentation Filter Disinfect Storage Source Water Metro Wastewater Collected pH Balanced with NaOH Ammonium Hydroxide added as nutrient for bacteria

Recycle Plant Process Collection Bio Process Coagulate Flocculation Sedimentation Filter Disinfect Storage Biological Filters Bio-Bacteria Sodium & Ammonia Nitrates Watch what you put in! Disturbed biomass shuts down the plant for a week while they replenish themselves.

Recycle Plant Process Collection Bio Process Coagulate Flocculation Sedimentation Filter Disinfect Storage Mixing/Particle Removal AlumCoagulant Coagulates small particles Open to the air Often have fish and or ducks in the water

Recycle Plant Process Collection Bio Process Coagulate Flocculation Sedimentation Filter Disinfect Storage This process rids the water of most large particles including the alum. Inside and covered Flocculation

Recycle Plant Process Collection Bio Process Coagulate Flocculation Sedimentation Filter Disinfect Storage Remove any large particles that made it through flocculation. (Fish, Light Particles) Everything was covered in a layer of rust. (Not everything filtered) Sedimentation

Recycle Plant Process Collection Bio Process Coagulate Flocculation Sedimentation Filter Disinfect Storage Filters Filters out the very small particles left in the water to make extremely clear water (turbidity < 0.5) Made of anthracite (a very hard pure form of coal) Troughs spread the water out so that the filter is used evenly

Recycle Plant Process Collection Bio Process Coagulate Flocculation Sedimentation Filter Disinfect Storage Disinfect and Store Chlorine disinfects water Stored in large (300 x 23 ft) round storage tanks. 11 million gallons Stored under parks or other large open spaces Pumped out to customers

Impressive Plant Beautiful architecture Everything color coated Cleanliness a priority Separate buildings keep things organized and cost efficient

Future Planning Changing Quality Standards High Security/Safety Bad Chemicals: Unsafe water in Denver homes and establishments

Future Planning Limited Potable Water Multiple Water Mains Conservation and Education Note: Use only what you need!

Constant Expansion 2007 Pump Station, Distribution Pipes, Storage Facilities 2010 Additional Water Mains

Conclusion Potable or nonpotable, the water is clean! Thank you! Acknowledgements Denver Water Pam Morse CHEN 1300 University of Colorado
