Water treatment can remove impurities and suspended particles from the water. Filtration is one of the critical steps in the water treatment process. Filters help remove impurities, pathogens, and other contaminants from water, making it fit for human consumption and other uses.
What type of filters are used in a water treatment plant?
1. Coarse Screens
The first filtration step is to remove large debris such as sticks, leaves, and other objects that could clog the treatment plant's equipment. Coarse screens(bar screens) remove these large objects from the water. These screens have openings that range from 1-6 inches in size.
2. Fine Screens
After passing through the coarse screens, the water flows through fine screens with smaller openings than coarse screens. Fine screens remove smaller particles such as sediment, algae, and other suspended solids. The openings in fine screens typically range from 1-10 mm.
These water filters can be used, such as:
Intake screen
Sieve bend screen
Filter Nozzle
Header and hub lateral
Wedge wire cylinder
Wedge wire pipe
3. Granular Media Filters
Granular media filters(rapid sand filters) remove suspended solids, bacteria, and viruses from the water. These filters consist of a bed of granular material, such as sand, gravel, or anthracite, through which the water flows. The granular material traps the impurities, allowing clean water to pass through.
4. Ion Exchange Resins
Ion exchange resins remove dissolved ions and minerals from the water. These resins are designed to exchange ions in the water with other ions in the resin, allowing the removal of impurities such as heavy metals, nitrates, and sulfates. Resin traps, filter nozzles, and lateral assemblies installed in the ion exchanger can be used.
5. Cartridge Filters
Cartridge filters are used as a final step to remove any remaining impurities from the water. These filters have a porous medium, such as a ceramic or polypropylene cartridge, that traps any remaining suspended solids and bacteria.
We can provide various types of water filters for water treatment plants.
