Polishing and Disinfection Systems

Polishing and disinfection steps are required to protect human health and critical process equipment from potential pathogens and elevated levels of minerals in the reclaimed water. Sustainable Water employs water polishing and disinfection systems that are designed to meet client end use water quality demands.

Ultraviolet (UV) Disinfection Systems

Ultraviolet (UV) disinfection utilizes high frequency light in the UV-C spectrum to denature the DNA of potential pathogens. Properly designed UV systems kill 99.99% of bacteria and viruses in reclaimed water. Sustainable Water typically uses UV as a primary disinfection method coupled with chlorine to provide a disinfection residual for reuse storage and distribution systems. Dual disinfection with online instrumentation for turbidity, UV dose, and chlorine residual assures reclaimed water is always safe for reuse.

Reverse Osmosis (RO) & Capacitive Deionization (CapDI)

Depending on wastewater source and reuse equipment, mineral elements in the reclaimed water may need to be reduced to optimize reuse for boilers and other process equipment. Reverse Osmosis (RO) and Capacitive Deionization (CapDI) membranes can be utilized to efficiently remove dissolved salts from reclaimed water. Sustainable Water has extensive experience with a variety of water polishing techniques and we work with leading equipment vendors to select the best technology for our projects.
