ClariCone® Clarifiers and FiltraCone™ Treatment Plants

CB&I is the original provider of the ClariCone® solids contact clarifier for potable water and wastewater treatment. CB&I's experience and know-how is unparalleled, with well over 300 ClariCone clarifier installations on a variety of applications treating in excess of 700 million gallons per day. As the only supplier that provides complete engineering, fabrication, construction and commissioning on an in-house basis, CB&I has the resources to deliver each project successfully. 

We’ve been providing complete design-build services for the water industry for more than a century. We are one of the few EPC companies that have the integrated resources to perform nearly all aspects of a project—from front-end design through construction—ourselves. This single-source approach helps us control quality, manage costs and deliver superior results. In fact, a number of our ClariCone clarifier projects have garnered awards for engineering excellence from the American Consulting Engineer’s Council. 

The economics of good design

The ClariCone clarifier’s design makes it more economical to operate and maintain than other water treatment systems. Mixing, tapered flocculation and sedimentation all take place within a completely hydraulically driven vessel. They are constructed entirely without mixers, scrapers, recycle pumps or other continuously moving parts, eliminating the need for oil changes and gear overhauls. 

The ClariCone clarifier maintains a dense, suspended, rotating slurry blanket that provides excellent solids contact, accelerated floc formation and exceptional solids capture. Thus, chemical usage is reduced and O&M costs are minimized. The conically shaped concentrator maximizes the slurry discharge concentration and allows plant personnel to visually monitor slurry discharge. 

Other benefits of the ClariCone clarifier include:

  • Space savings—The area beneath the ClariCone clarifier’s conical shell can be used for other equipment, and the small diameter of the lower cylinder reduces founclardraw1a_v3.pngdation costs.
  • Stability—The large mass of retained slurry and unique helical flow pattern prevents short-circuiting and resists upsets.
  • Intermittent operation—Following a shutdown, the ClariCone clarifier can be restarted in minutes, compared with hours or days for conventional units. 

We also offer our patented FiltraCone™ modular water treatment system. The FiltraCone system brings together the ClariCone clarifier with self-backwashing peripheral filters in a fully enclosed system, providing exceptional treated water quality with minimal maintenance, power use and cost. 

Our company is unsurpassed in water industry expertise. With a century of experience and thousands of water storage and treatment projects to our credit, we have a record of proven results and in-depth knowledge.
