Use Cases & Applications

  • Municipal Water and Wastewater Treatment: Long box clarifiers are used in municipal treatment plants for primary and secondary sedimentation processes, efficiently separating solids from water to produce clear effluent and concentrated sludge, enhancing overall treatment capacity and efficiency.
  • Industrial Process Water Treatment: In industrial applications, these clarifiers treat process water to remove suspended solids, ensuring the water quality is suitable for reuse or discharge, supporting industries like mining, metal processing, and chemical manufacturing in meeting environmental compliance.
  • Construction Site Runoff Management: For construction projects, long box clarifiers provide an effective solution for treating site runoff water, removing sediment and pollutants before discharge, helping to prevent contamination of local waterways and comply with stormwater regulations.
  • Emergency Water Treatment: They serve as an immediate solution for emergency water treatment needs, such as after a natural disaster or in the event of a plant failure, ensuring continued water treatment capacity and preventing environmental pollution.
