Quartz sand filters mainly use the principle of quartz sand retention and adsorption to remove impurities in water, while activated carbon filters use the rich capillaries of activated carbon to adsorb and filter macromolecular organic matter, residual chlorine and other colloidal substances in water. The quartz sand filter only needs backwashing, so in order to protect the activated carbon filter, the quartz sand filter is generally placed in front of the activated carbon filter to protect the activated carbon filter and extend the service life of the activated carbon.
The above is an introduction to the use of quartz sand filters with activated carbon filters. If you have other questions, you can leave a message at the end of the article, I will reply to you in a timely manner!
