Why can the existing water treatment plants remove the chloride?
They can be modified, but the treatment needed (micro filtration and reverse Osmosis) is very costly. It will cost the Sanitation Districts and its customers more than $ 300 million to construct additional treatment to remove chloride from wastewater if the amount of chloride entering the sewers is not reduced by residents. Approximately 50 percent of this expense is due to the cost of installation of a 46-mile pipe (brine line) to take the salt waste produced during treatment to the ocean and the installation of a three-mile underwater pipe at the ocean.
