What is clariflocculation?

Clariflocculation is a combination of flocculation and clarification in a single tank. The equipment used for this process is the clariflocculator.

The clariflocculator is a system containing two concentric tanks:

  • inside as a flocculation basin
  • outdoor clarifier

Clarifloculation process

This is a necessary process for treating water with high levels of TSS and other contaminants.

  • In a clariflocculator, the water moves into the flocculation tank, where the paddles stir it up.
  • this stirring will then create more flocs
  • when these flocs settle to the bottom, the liquid flows radially upwards into the clarificator area
  • the clarified liquid is then discharged through a peripheral weir into the peripheral washer
  • the sedimented sludge is then raked to the bottom of the central weir. Once there, it is transferred to the sludge chamber and discharged.

This equipment will then be used in larger installations.

Clariflocculator design

To optimize clariflocculator design, it is important that we have access to information such as :

  • Turbidity
  • TSS
  • Appearance and color of water to be treated
  • Daily consumption
  • Instantaneous system flow,
  • Type of application
  • Other physico-chemical characteristics (PH, water temperature, salinity).

So we can suggest the clariflocculator that will meet all your expectations.

Specific advantages of 1h2o3 clarifloculators

  • Custom-built: We manufacture all our clarifloculators specifically to suit your needs. These include:
    • position and type of inputs/outputs
    • volumes of neutralization/coagulation/flocculation tanks.
  • High resistance: Our clariflocculators are made of corrosion-resistant polypropylene and can withstand the entire pH range.
  • Drinking water compliance: Some countries require specific materials for drinking water applications (NSF-61, ACS, DVGW, SVGW..). We can adapt the materials of our clariflocculators to meet your specific regulations.
  • Internal bypass: when the volume is divided into two sections, each section can be isolated separately by means of an internal bypass device (except CFC.DLC).
  • 3 installation modes: thanks to the thickness of the polypropylene walls, the tanks can be installed completely either:
    • completely buried
    • partially buried
    • just on a slab
  • Outdoor use: to reduce factory floor space, the tanks can be covered with anti-slip hoods and their panels reinforced with an anti-UV treatment.
  • Eco-design: Unlike fiberglass, all materials used in our equipment are 100% recyclable.
  • Specific industrial applications: triple skin tank, high temperature fluids… Everything is possible, just ask us!
  • Lamella thickness: while many suppliers offer lamellas with a thickness <1,5 mm, Our lamellas are 3 mm thick. This thickness makes the structure much more resistant to clogging due to lack of maintenance and prevents the risk of collapse.
  • Separate collection of floating sludge: our twin weir channel makes it possible to collect them separately:
    • decanted water: treated water
    • floating sludge: the floating fraction on the surface of lamella clarifiers which, if not collected separately, decreases efficiency in TSS, COD, BOD5.
