If so, will it remove all or most of these compounds? I have read that reverse osmosis tends to remove everything, but I was not sure about microfiltration.
Yes, pharmaceuticals, hormones and other non-regulated contaminants are being removed to below detectable levels by the advanced treatment processes that has been added to the Plum Creek Water Purification Facility as part of our reuse project. The processes added include ozone treatment, biologically active carbon filtration, ultraviolet radiation and granular activated carbon filtration. These are in addition to microfiltration, which is already used at the facility. Microfiltration is very similar to, but not quite as extensive as, reverse osmosis. There are now a total of nine different treatment processes to provide redundancies ensuring a pure water with efficiencies for equipment and operations.
Regardless of where our water originates, Castle Rock Water must meet very strict state and federal regulations to provide clean and safe water. In fact, the wastewater treatment plant also must remove contaminants from water before releasing it into the creek, as communities downstream are already picking this water up to treat it for drinking water.
