Dealkalizer Plant:

A dealkalizer, also known as an anion exchange system, is a water treatment technology used to reduce the alkalinity of water by removing alkaline minerals, primarily bicarbonate and carbonate ions. Alkalinity refers to the capacity of water to neutralize acids, and high alkalinity levels can lead to issues such as scaling, corrosion, and interference with certain industrial processes.

Process Description

The flocculation process in a clariflocculator allows the suspend particles to collide, adhere to each other, and form larger and heavier flocs. The flocculation is usually achieve by the use of mechanical agitators, rotating paddles, or a combination of both, which provide the necessary mixing and contact between the particles and flocculants.
After the flocculation stage, the water proceeds to the settling stage within the same tank. The velocity of the water flow is reduce, allowing the form flocs to settle to the bottom of the tank by gravity. The settle particles, along with the form sludge, are collecte and remove as sludge from the tank.

Design Configuration:

The clariflocculator consists of a large tank with a central inlet for the water to be treate. The water enters the tank and is subject to a gentle mixing or stirring action, similar to flocculation. During this flocculation stage, coagulants and flocculants may add to aid in the aggregation of suspend particles into larger flocs.

Significance & Advantages

Space Efficiency: By integrating the flocculation and sedimentation processes into a single tank, the clariflocculator requires less space compare to separate flocculation and sedimentation units.
Improve Settling: The flocs that form during flocculation are larger and heavier than individual particles, which enhances the settling process and improves the efficiency of suspend solids removal.
