For large camps with populations expected to exceed 2,000 people, newterra’s modular PWT-500 Potable Water Treatment Large Train System employs 40' containers dedicated to a specific, complimentary treatment process (e.g. greensand filtration, nanofiltration, etc.). This is a more efficient approach to addressing source water variability. Individual containerized treatment units have a 500 m3 capacity (136,085 US gal) and are interconnected to provide the complete treatment process train. The system can be configured for both groundwater and surface water sources.
