WesTech’s package plants are complete water treatment systems in a single tank. They treat from 10-1,400 gallons per minute of source waters, depending on the plant. From the TRIDENT® line to our new RapiSand Plus™, our package plants are modular: Organizations can easily add tanks to meet increasing demands. All our package plants, including RapiSand Plus, are prefabricated, making them ideal for remote locations and rugged terrain. RapiSand Plus includes a process of ballasted flocculation followed by media filtration to treat high-solids waters that contain contaminants such as iron and manganese.
