Mobile and compact water treatment plants can produce safe drinking water from a variety of sources for areas without water infrastructure. These modular systems can be installed permanently or semi-permanently with minimal site preparation. They are suited for temporary water supply. Some models are powered by solar panels and batteries to operate independently without traditional energy sources. Compact plants optimize water treatment technologies in small spaces and can incorporate additional equipment like generators, storage tanks, and pumps into complete water treatment solutions. They employ various purification methods depending on the water source and quality.
