Описание: Visit to one of the Champaign-Urbana sanitary district waste treatment plant. How they treat 13,000 gallons of waste water per minute – which is 7 billion gallons per year for 140,000 people. How sewage comes in at one level of solids in the water and leaves at a dramatically lower level. Detailed explanation, video and demonstration of the five steps: Screening, Fat Happy and Reproducing Microbes, Settling, Nitrifying, Filtration. What nature does in 12 days is done in the plant in 12 hours.
