PFAS FILTER SYSTEM Drawing.pdf

The image is a detailed piping and instrumentation diagram (P&ID) for a water treatment system designed to remove PFAS (Per- and Polyfluoroalkyl Substances) from a water supply, likely for a public school system. The diagram, created by Fitch Engineers, shows a comprehensive water filtration process involving an existing water supply well, ex well pump, booster pump, and a series of pressure tanks and carbon adsorbers. The system includes multiple lead and lag carbon adsorber units, pressure indicators, sampling ports, flow meters, and a UV disinfection unit, with the ultimate goal of delivering potable water to a school.

The technical drawing includes several critical notes, such as that not all existing piping system elements are depicted, a bypass valve will be installed with a locking mechanism, and the proposed vessels, piping, and media will be NSF 61 and NSF 372 certified. The system appears to be part of a broader water treatment infrastructure project addressing PFAS contamination, with specific design considerations for water quality and safety. The diagram uses standard engineering symbols to represent valves, pumps, filters, and measurement instruments, providing a clear schematic of the water treatment process flow and key components.
