Ettefiltratsiooni

Ettefiltratsiooni is a process used in water treatment to remove suspended solids, colloids, and other impurities from water before it enters a filtration system. This preliminary step is crucial for improving the efficiency and lifespan of subsequent filtration processes, such as slow sand filtration or rapid gravity filtration. Ettefiltratsiooni can be achieved through various methods, including sedimentation, flocculation, and coagulation.

Sedimentation involves allowing particles to settle out of the water under the influence of gravity. This method is effective for removing larger particles but may not be sufficient for smaller colloids. Flocculation, on the other hand, involves the addition of chemicals to water to cause smaller particles to clump together, forming larger, heavier particles that can be more easily removed through sedimentation. Coagulation is a similar process that uses chemicals to neutralize the electrical charges on particles, allowing them to come together and form larger aggregates.

The choice of ettefiltratsiooni method depends on the specific characteristics of the water being treated, including the types and concentrations of impurities present. In some cases, a combination of methods may be used to achieve the desired level of water purification. Effective ettefiltratsiooni is essential for ensuring the quality and safety of drinking water, as well as for protecting downstream filtration systems from damage and reduced efficiency.
