  • Simul-Wash™

    Simul-Wash™ is a proven sustained, simultaneous air/water filter backwash system that extends the life of filter media, minimizes backwash waste, prevents mudballs from forming and frees nearly all captured filter debris – better than any other backwash method available. Simul-Wash™ works well in a variety of configurations, from horizontal and vertical pressure filters to low profile retrofit applications on gravity filters.

    Tonka Water’s Simul-Wash™ backwash system is the only sustained air and water backwashing process using the “collapse-pulse” technique first documented by Amirtharajah in a landmark AWWA Research Foundation. Simul-Wash™ also meets Ten States Standards and has a low profile baffled trough design providing long and clear spans. Stainless steel is the standard construction for components uniquely suited for “vertically challenged” filters.

    Simul-Wash™ is applicable with manganese green...

  • Dualator® VI

    The Tonka Water Dualator® VI is a free-standing package treatment unit that incorporates aeration, detention and filtration in a circular configuration. In moderate to warm climates, it can be placed exterior to the water treatment plant, with functional piping and valves extended to within the building for protection from the elements. When placed interior to the water plant, the aerator and detention sections of the unit typically extend through the roof, to prevent freezing and to allow for access to filtration from within the building. The Dualator® VI is self-backwashing, eliminating the need for a separate backwash pump and supply. It does not provide baffled detention or solids sedimentation, as all water is delivered to the four-cell filtration compartment after aeration.

    The oxidation of iron is completed via an induced or forced draft aerator integral to the unit. After approximately 30 minutes of detention, water is filtered and ready for distribution.

  • Heli-Cone™

    Tonka Water’s Heli-Cone™ provides turbidity removal in a single hydraulically driven unit. It is ideal for high turbidity surface waters, lime softening, iron and manganese, and pre-sedimentation.

    The Heli-Cone™ has a multitude of advantages over other clarification systems, including having no mechanically moving parts; inherent mixing, coagulation and tapered flocculation; a large retained slurry mass for high solids contact; helical flow hydraulics; easy slurry blanket re-suspension upon start-up and a controllable slurry concentrator for solids disposal.

    The Heli-Cone™ up-flow solids contact clarifier is a proven hydraulically driven system designed to form and maintain a rotating, conical-shaped slurry blanket, through which water flows upward in an expanding spiral path. This design minimizes the energy input required for the maintenance of a slurry blanket and eliminates the mechanical problems associated with conventional clarifiers. The...

  • TriClear™

    Tonka Water’s TriClear™ conventional propeller solids contact clarifiers are versatile upflow clarifiers suitable for a wide variety of solids removal applications.

    The advantages of Tonka Water’s TriClear™ solids contact clarifiers include a compact footprint; enhanced coagulation; tapered internal flocculation and proven upflow clarification. The clarifiers combine mixing, coagulation, clarification and sludge removal, and can be constructed for steel or concrete basins.

    Raw water flows into the internal draft tube where it is mixed with a high-speed propeller mixer, and is brought into contact with previously formed solids. The mixture then coagulates and enters the interior inverted conical flocculation area where energy is dissipated prior to upflow by radial collection launders. Settled solids are simultaneously removed by full-floor mechanical scrapers.

  • SpiraClear™

    The SpiraClear™ has a small footprint and uses “pelletized” technology for lime softening systems.

    The SpiraClear™ is of an efficient design, compact footprint and has a unit flow rate up to 700 gpm. Limestone pellets are produced instead of sludge, eliminating salt waste created from regeneration. The SpiraClear™ is particularly suitable for higher calcium, lower magnesium type hardness.

     Tonka Water’s SpiraClear™ is used to soften water by forming limestone pellets as the pH-adjusted water travels upward in a helical flow pattern. The SpiraClear™ is hydraulically designed with a water influent to enter tangentially at the base of the vessel which causes a swirling upward motion of the water. The helical swirling motion ensures thorough and uniform contact between the added softening catalyst and the water. The upward motion maintains the granular bed in a fluidized condition, with calcium precipitation on the granu...
