sügavfiltratsiooniks

Sügavfiltratsiooniks, also known as deep filtration, is a process used in water treatment to remove fine particles, colloids, and microorganisms from water. This method is particularly effective in treating water that has already undergone preliminary treatment, such as coagulation and sedimentation. Deep filtration typically involves the use of granular media filters, such as sand, anthracite, or garnet, which are layered in a filter bed.

The process begins with the water being slowly passed through the filter bed. As the water moves downward, it comes into contact with the filter media, which traps and retains the fine particles and microorganisms. The filtered water then exits the filter bed and is collected for further treatment or distribution.

Deep filtration is highly effective in removing a wide range of contaminants, including bacteria, viruses, protozoa, and small particulate matter. The efficiency of deep filtration can be influenced by factors such as the type and size of the filter media, the depth of the filter bed, and the rate of water flow through the filter.

Regular backwashing and rinsing of the filter bed are essential to maintain the effectiveness of deep filtration. Backwashing involves reversing the flow of water through the filter bed to dislodge and remove the trapped contaminants. Rinsing follows backwashing to remove any remaining contaminants and restore the filter bed to its original condition.

Deep filtration is widely used in water treatment facilities to produce high-quality drinking water. Its ability to remove fine particles and microorganisms makes it a crucial step in ensuring the safety and quality of water supplies.
