Plant in Colorado Utilizes Coagulation Filtration Treatment in a Single Packaged Unit

The town of Antonito, Colorado was in need of a new water treatment plant. With the assistance of Tonka Water, a U.S. Water Brand (Tonka Water), they worked to design a new water treatment system meeting both ten state standards and Colorado standards for conventional surface water treatment. The system includes Tonka Water’s Unitized Treatment System™ (UTS™) featuring a Simul-Wash™ backwash system. This robust system is easy to operate and allows for flexible chemical application.

Tonka Water’s UTS is an enhanced coagulation filtration treatment process in a single packaged unit. The UTS surface water treatment unit consists of an integral two-stage flocculation compartment, tube settling, and filter compartments. The filters contain a dual media of silica sand and anthracite, and feature Tonka Water’s Simul-Wash backwash system. Chemical addition occurs prior to the flocculation zone to assist in turbidity removal. Following flocculation, the water travels through high-efficiency tube settlers, removing the majority of solids prior to filtration.

Tonka Water’s UTS utilizes collapse pulse backwash technology by combining air and water at subfluidized flow rates. The Simul-Wash trough allows the simultaneous air/water backwash cycle to be extended indefinitely without the loss of media. This extends filter runs, lengthens the useful life of the filter media, prevents mudballs and frees nearly all captured filter debris, using fifty percent less backwash water than convention backwash systems.

The water treatment system design uses state-of-the-art technology to maximize treatment plant production and minimize operating costs. Since its commissioning in 2017, the Antonito treatment plant has been meeting water treatment expectations.
