What is a Clariflocculator in Wastewater Treatment?

You are currently viewing What is a Clariflocculator in Wastewater Treatment?

Wastewater treatment is a complex process involving several stages to remove contaminants from industrial and municipal water. One of the most efficient technologies used in the primary treatment phase is the clariflocculator. It combines clarification and flocculation processes in a single unit to remove suspended solids, making it an ideal solution for large-scale water and wastewater treatment systems.
We design and manufacture high-performance clariflocculators that offer reliability, space efficiency, and operational ease for industries and municipal setups alike.

Working Principle of Clariflocculators

The working principle of clariflocculators is based on the dual action of flocculation followed by clarification. Initially, raw water enters the flocculation zone where a chemical (like alum or polymer) is added. This causes fine particles and colloidal matter to aggregate into larger flocs.
Next, the water flows into the clarifier section where the heavier flocs settle at the bottom due to gravity. The clarified water is collected from the top via peripheral launders, while sludge is periodically removed from the bottom. The working of a clariflocculator_ ensures efficient solid-liquid separation, reducing turbidity and improving overall water quality.

Process Flow for Clariflocculators

The process flow for clariflocculators involves the following stages:

  • Chemical dosing to aid floc formation
  • Inlet of raw water
  • Slow mixing in the flocculator to aggregate particles
  • Flow into the clarifier for sedimentation
  • Collection of clarified water
  • Discharge of sludge from the hopper
The process can also be illustrated as:

Application Areas of Clariflocculators

Clariflocculators are used across a variety of sectors due to their effectiveness and compact design. Application areas of clariflocculators include:

  • Municipal water and sewage treatment plants
  • Industrial effluent treatment facilities
  • Power plants
  • Chemical processing industries
  • Paper and pulp industries
  • Textile dyeing and finishing units
  • Food and beverage manufacturing units

Advantages over Conventional Equipment’s

Clariflocculators offer several advantages over conventional equipment’s, including:

  • Space-saving design by integrating flocculation and clarification
  • Reduced operational cost due to lower energy and chemical usage
  • High treatment efficiency for large water volumes
  • Minimal maintenance with sturdy mechanical components
  • Ease of operation and automation compatibility

These advantages make clariflocculators a preferred choice over separate clarifier and flocculator units, especially in space-constrained industrial environments.
