What are small, prefabricated units designed for water treatment called?

The correct terminology for small, prefabricated units designed for water treatment is "package treatment plants." These units are built off-site and can be transported to the location where they are needed, making them highly versatile and efficient for treating water in various settings, including remote or smaller communities.

Package treatment plants are designed to handle a specific flow rate and can include various treatment processes such as screening, sedimentation, filtration, and disinfection all within a compact design. Their prefabricated nature means they can be quickly installed and often require less on-site construction, making them ideal for expedited deployment in situations where immediate water treatment solutions are necessary.

While terms like "modular treatment plants" or "skid-mounted treatment units" may describe similar concepts, they can imply different arrangements or configurations which do not explicitly denote the compact, prefabricated aspect that "package treatment plants" emphasize. Understanding this distinction is critical in the context of water treatment options available for diverse applications.
