Pressure Filters: Tonka Water’s customized pressure filtration systems are configured to meet your project’s specific requirements. Individual units vary from vertical (low flow) to horizontal (higher flow) and feature backwashing with our unique water-saving Simul-Wash™ backwash system. All of Tonka Water’s pressure vessels have the ASME stamp affixed, assuring superior structural design and compliance with the latest codes and constructed to meet the highest quality standards.

Tonka Water’s OptaCell Pressure Filter – Our Most Versatile Pressure System

  • Customizable with multiple cells
  • Self-backwashing
  • OptaCell Plus™ design – isolated cells for stand-alone redundancy
  • Low headloss arched plate underdrain
  • End-piped or side-piped
  • 8, 10, or 12 foot diameter units to accommodate a wide flow range
  • Space-efficient piping
  • Customized controls for system responsibility

Tonka Water's VertaCell Pressure Filter

  • These systems utilize vertical vessels where individual filters are placed side by side. They are ideal for smaller flows and buildings accommodating higher headroom but compact footprints.
  • Customizable diameters and side shell heights.
  • False bottom underdrains available.
4 Vessel Water Treatment System


The Centralator™ is a four-cell cluster gravity filter, usually of concrete construction, exhibiting the most efficient overall system footprint for new construction. The Centralator™ system has a capacity range from one MGD to over 30 MGD. It is a cost-effective system that is self-backwashing, requiring no backwash pump or even pipe galleries. It is an excellent system for any filtration application and can easily accommodate our Simul-Wash™ backwash process to make it an even greener technology.
