Filtration

Definition

Filtration is a process used in water treatment where suspended particles and impurities are removed by passing the water through a porous medium (such as sand or activated carbon). This helps to improve the clarity and quality of the water.

The process of allowing suspended particles in water to settle down under the influence of gravity.

Coagulation: The process of adding chemicals (coagulants) to water to help clump together fine particles, making them easier to remove during filtration.

Reverse Osmosis: A specialized form of filtration that uses pressure to force water molecules through a semipermeable membrane, removing even smaller contaminants.
