Conventional Clarifier

Krofta offers central driven and peripheral driven conventional clarifiers used to remove solid particles and impurities from water. It operates on the principle of gravity settling, where solid particles settle down in a quiescent (motionless) zone, allowing clean water to separate and rise to the surface.

Here's how a conventional clarifier typically works:

Inflow of Water

Water containing suspended solids and impurities enters the clarifier tank through an inlet. This incoming water is often referred to as influent.

Quiescent Zone

Inside the clarifier, the velocity of the influent is significantly reduced, allowing the water to come to a state of calm or quiescence. Solid particles begin to settle.

Settling Zone

The settled particles gradually sink to the bottom of the clarifier tank due to their weight. The settling time depends on size, weight, and water dynamics.

Sludge Collection

The settled particles accumulate as sludge at the bottom of the clarifier. This sludge is composed of various organic matter, minerals, and suspended impurities.

Sludge Removal

To prevent the buildup of excessive sludge, a mechanism is employed to remove it from the bottom of the tank using a bottom-mounted scraper arm.

Overflow Weir

Clarified water nears the surface and flows over a peripheral weir or baffle, which stops fine particles from escaping with the clear water layout.

Effluent Collection

The clarified water that flows over the weir is collected cleanly in a launder and directly routed for downstream treatment processes or final distribution.
