Can you Explain the Filtration Process Within a Media Filter Tank
Inlet of untreated liquid: The untreated liquid, which may contain suspended solids, debris, and contaminants, enters the media filter tank through the inlet pipe.
Distribution system: The distribution system evenly distributes the incoming liquid over the surface of the filtering medium. This ensures uniform contact between the liquid and the media for effective filtration.
Passage through filtering medium: The liquid passes through the filtering medium inside the tank. The type of filtering medium, such as sand, activated carbon, or diatomaceous earth, determines the mechanism of filtration.
Sand filters: Sand filters operate through mechanical trapping and physical adsorption. Larger particles are trapped in the sand bed, while smaller particles may be captured by the adsorption capacity of the sand.
Activated carbon filters: Activated carbon operates through adsorption, where organic compounds and certain chemicals adhere to the carbon surface. It is effective in removing impurities that contribute to taste and odor.
Diatomaceous earth filters: Diatomaceous earth filters use the fine porous structure of diatom skeletons to capture extremely small particles. The earth forms a filter cake on the surface, trapping particles during the filtration process.
Capturing and retention of particles: The filtering medium captures and retains suspended solids, impurities, and contaminants present in the liquid. This process can occur through various mechanisms, including mechanical trapping, adsorption, and the formation of a filter cake.
Outlet of treated liquid: The filtered or treated liquid exits the media filter tank through the outlet pipe. The liquid is now free from the captured impurities, resulting in improved water quality.
Maintenance and backwashing: Over time, the filtering medium may become clogged with captured particles, reducing its efficiency. To address this, media filter tanks often undergo a backwashing process. During backwashing, the flow of water is reversed, dislodging and flushing out accumulated debris from the filtering medium. This helps restore the medium's effectiveness.
Disposal of captured particles: The captured particles and impurities removed during backwashing are typically directed to a drain or waste disposal system, preventing them from re-entering the treated liquid.
