    Coagulation and Flocculation

    You start the hotel wastewater treatment process by adding chemicals that help small particles stick together. This step forms larger clumps called flocs. These flocs settle faster and make it easier to remove pollutants. When you combine coagulation and flocculation with other methods, you can reclaim over 95% of water. This high rate helps you keep your hotel’s water clean and safe.

    Sedimentation

    After flocculation, you let the water sit in a tank. The heavy flocs sink to the bottom. You remove these solids, which reduces the amount of pollution in the water. Sedimentation makes the next steps more effective.

    Filtration

    You use filters to trap any remaining particles. Hotels often use sediment filters, activated carbon filters, and reverse osmosis membranes. These systems remove sediments, chlorine, odors, minerals, and salts. You also improve water taste and quality for your guests.

    • Common filtration systems in hotels:
      • Sediment filters
      • Activated carbon filters
      • Reverse osmosis membranes

    Disinfection

    You disinfect the water to kill harmful microbes. Chemical and physical methods reduce microbial contaminants by up to 49% and 41%, respectively. Chemical disinfection removes over 91% of Legionella bacteria. You can see the effectiveness in the chart below:
