2 x 60 m³/h ultrapure water for power plant - WTP in 6 x 40’ containers

Reference ID: 022200
Industry: Heat and power plants
Application: Boiler water

The existing water treatment plant was supplied in 1970. An upgrade of the water treatment plant was required, but no free space at site was available. Also, the construction works on-site was requested to be minimized. It was decided to order the equipment built inside 40’ containers. Site installation was reduced to the pipe system and the electrical wiring between the containers.
