Abstract: In this lab, we were introduced into the steps that the San Diego Water Treatment plant does to clean and filter that water that goes into millions of homes in San Diego. The purpose of this lab was to correctly follow the safety procedures that the San Diego Public Utilities Water and Wastewater plant have to follow so that we can raise our awareness of our own backyard, our own streets, our own oceans, and our own world. First, we created our own wastewater by mixing dried up coffee grounds, ground-up cereal and pet food, cut up plastic bags, baking soda, torn up toilet paper, vegetable oil, and ammonia into water. The end result looked like actual wastewater. We proceeded to do the primary, secondary, and advanced treatment steps to treat the wastewater. …show more content…
The secondary treatment consists of putting in microorganisms to consume the dissolved waste. The advanced treatment consists of filtrating and disinfecting the water. In between each of these three steps, we conducted several tests to test for key factors that determined whether or not the water is clean. We tested for pH, ammonia concentration, turbidity, and COD. Turbidity measured suspended particles in the water and the clarity of the water. COD stands for chemical oxygen demand and measures the amount of dissolved oxygen that would be removed from the water to react with pollution. In our end results, the water passed all four-test regulations and was indeed clean water. The pH of clean water should be between 6.0 and 9.0 and ours was 6.17. The ammonia concentration was no limit, but our concentration was very low at .18 mg/L. The turbidity levels in clean water should be less than 4 FAU and ours was 0.39 FAU. The COD levels
