PROBLEM PROPOSED BOARD 1 PARTS TO THE SYSTEM PROPOSED BOARD 2 How does one work? Throughout time, Wastewater Treatment Plants have been separated What are the steps of a treatment plant? from the identity and representation of neighborhoods they live in. This creates a major disconnect from those who live near a facility and the valuable service they perform. I am looking to replicate and distribute these A. Basic steps to a treatment plant systematic processes of the organic levels of a waste water treatment plant 1. Primary treatment throughout the urban area. a. grit chamber b. primary clarifjer BACKGROUND 2. Secondary treatment History of the WWTP in the Urban Context a. aeration system - players and key historical refernces b. secondary clarifjer - Ivan Illich and “Miasma Theory” c. digester - How have health practices changed in urban areas 3. [Different types of steps after the 2nd treatment] - TODAY Tertiary treatment (if beyond second is needed) - NIMBYisms, etc a. chemical treatment - chlorination - Locations of WWTP in NYC, size and b. physical treatment - sand fjlters related information. c. biological treatment - wetland
