Technology comment
Reclaimed water treatment processes include physical, chemical, and biological treatments. Physical treatment mainly includes sedimentation, clarification, filtration, and membrane separation, which are used to remove suspended solids, particulates, and colloids. Chemical treatment employs chemical reagents to adjust pH, precipitate, and adsorb pollutants, such as using coagulants and adsorbents. Biological treatment utilizes microorganisms to degrade organic matter and remove nutrients such as nitrogen and phosphorus through biodegradation and bioadsorption.
