In this effort, a decentralized grid-independent, zero-carbon-footprint water treatment system is developed. The system utilizes a micro-filtration pre-treatment, a two-stage reverse osmosis, and an ultraviolet disinfection post-treatment. The system is solely powered by solar-photovoltaic panels through a battery bank. The developed system is capable of desalinating and disinfecting a permeate flow rate of 1.2-1.8 gpm with a recovery rate of 60-80%.  A minimum salt rejection rate of 97.5% is achieved at 140 psi of feed water pressure.
