Conventional clarifier
Krofta offers central- and peripheral-driven conventional clarifiers designed to remove solid particles and impurities from water through gravity settling. In these systems, water enters the clarifier tank through an inlet, which is referred to as influent. The influent’s velocity is significantly reduced inside the clarifier, creating a calm or quiescent zone. This allows solid particles to settle to the bottom of the tank under gravity’s influence.

The settled particles accumulate as sludge at the bottom, known as the settling zone. The time required for particles to settle depends on their size, weight, and the water’s characteristics. A scraper arm at the tank’s bottom removes the sludge to manage sludge buildup.

As the particles settle and the clarified water rises, it reaches the surface where a weir or baffle installed at the tank’s periphery allows the clear water to flow over while retaining fine particles. The clarified water is then collected in a launder for further treatment or distribution.

Popular applications
Krofta Engineering Limited’s conventional clarifiers are widely used in various applications, including municipal sewage treatment plants, industrial effluent treatment plants, and common effluent treatment plants.
