aquaray* 40HO UV Disinfection Systems

Disinfection for wastewater plants with small footprints

The aquaray 40HO (high-output) system offers powerful UV disinfection in a minimized footprint due to their vertical lamp design. aquaray 40HO UV products are designed and validated for even the most stringent of effluents including wastewater reuse applications.


aquaray 40HO System Overview

The aquaray 40HO vertical lamp ultraviolet disinfection system has been designed to provide disinfection for wastewater plants within a small footprint. The germicidal effect of the UV light inactivates most microorganisms such as bacteria, viruses and parasites, while eliminating the need for dangerous chemicals. 

UV disinfection is particularly effective against chlorine resistant microorganisms and is an ideal solution for reuse applications.
