The Complex Process Of An Urban Water Supply System - CleanTechnica

The article from CleanTechnica provides an insightful overview of the complex urban water supply system in southeastern Florida, highlighting the multi-step treatment processes that ensure clean and safe drinking water for the local population. The water supply originates from two aquifers: a shallow one about 100 feet deep treated through an 8 million gallon-per-day lime process involving pH adjustment, coagulation, filtration, and chloramine disinfection; and a deeper aquifer approximately 1,350 feet deep treated by two reverse osmosis facilities processing 11.15 and 22.5 million gallons per day respectively. The reverse osmosis process includes chemical pretreatment, filtration, high-pressure membrane separation, degasification, pH adjustment, and final disinfection with fluoride added before distribution. The article also details the types of contaminants targeted by the treatment system, including microbiological agents (viruses, bacteria), inorganic substances (salts, metals), pesticides, organic chemicals, and radioactive materials, all of which can originate from
