1. Introduction
Treated water refers to clean, potable water supplied by the local water authority after undergoing several treatment processes such as coagulation, sedimentation, filtration, and disinfection. At Politeknik Sultan Salahuddin Abdul Aziz Shah (PSA), treated water is mainly supplied by Air Selangor Sdn.
