Customizability Water Treatment System - Composite Filter
1 . Descriptions:
Composite filters are efficient water treatment equipment that combine various filtration technologies and materials. Typically, composite filters use multiple layers of different types of filtration media, such as sand, quartz sand, activated carbon, and diatomaceous earth, with each layer serving a specific filtration function. The arrangement of these media layers can be customized based on the requirements and objectives of water quality treatment, making them ideal for both wastewater treatment systems and pure water treatment systems.
In composite filters, activated carbon and other adsorbent media can effectively adsorb organic matter, odors, and some dissolved chemicals, improving the taste and quality of water. Some composite filters may also include a biological filtration layer for the removal of microorganisms and nutrients needed for microbial growth. Like other filters, composite filters require backwashing after a period of operation to remove accumulated dirt and impurities, maintaining filtration efficiency and extending the media's lifespan in both wastewater treatment systems and pure water treatment systems.
