Three Vital Processes for Effective Water Clarification

Water Treatment PlantMost of the water that flows into our homes contains various contaminants either in soluble or insoluble form. The soluble contaminants are usually minerals the water absorbs or dissolves as it flows. The insoluble contaminants include dust, soil, and leaves. The larger insoluble particles are easier to remove from the water through filtration, unlike the fine particles.

Clarification Process

Often, fine particles found in surface repel each other since most of their surfaces are negatively charged. To separate the particles, the water has to go through a clarification process. The pros from ashtuck.com share that the entire clarification process may include coagulation, sedimentation, and flocculation and is known as conventional clarification. Clarification process removes all kinds of sediments, organic matter, particles, and colour.


Coagulation involves the addition of iron or aluminium salts. These salts neutralise the negative charge on particles and hydrolyze the insoluble precipitates. Water-soluble organic polymers that contain ionised sites can also effect coagulation.


During flocculation, the decentralised particles during coagulation aggregate to form large precipitates through slow and gentle mixing. Flocculation takes about 45 minutes and takes place in different compartments. The mixing speeds vary with the basins and often as water flows from the top to bottom of the basin the speed decreases.


After flocculation, the agglomerated particles enter a clarifier unit. The particles then float are removed through sedimentation or are skimmed from the surface. Through sedimentation, most solids settle by gravity. Sedimentation occurs in circular or rectangular basins that contain inclined basins which increase the surface area for sedimentation, making the process more effective. Filtration then removes the remaining materials.

For an effective water clarification process, it is good to acquire quality clarifier or thickener units from leading water treatment equipment suppliers. Your clarifier like any other machine will need regular maintenance to keep performing its role. In case you need to renovate an old thickener or clarifier, a retrofit drive unit is a suitable and economical solution.
