SediCore® Softening Hardness Remove Clarifier

     SediCore® Softening  sedimentation tank integrates microsand ballasted flocculation sedimentation technology and chemical softening technology into a combined treatment process, serving as an advanced hardness removal treatment solution.

     Process Principle

      The basic principle of the microsand softening sedimentation tank is to add a chemical reaction zone at the front end of the microsand sedimentation tank. Crystal nuclei of calcium and magnesium precipitates are recirculated to boost contact with raw water, inducing rapid precipitation reactions of calcium and magnesium ions in the raw water. Massive calcium and magnesium precipitates generated in the water are then rapidly separated in the downstream microsand sedimentation tank. This tank greatly accelerates chemical reaction rates, shortens sedimentation time and improves overall treatment efficiency. 

      Core Functions

      Integrating efficient processes of reaction, coagulation, sedimentation and sludge thickening, the SediCore® Softening microsand softening sedimentation tank is widely applied for hardness removal from surface water sources in water supply projects, as well as hardness and turbidity reduction of municipal wastewater and industrial wastewater.SediCore® Softening 

      Process Advantages

• High treatment efficiency

  The upflow velocity in the sedimentation zone normally ranges from 60 to 80 m/h, delivering treatment efficiency more than ten times that of conventional sedimentation tanks while producing low-hardness effluent.
• Compact footprint

  Its floor area is only 1/2 ~ 1/3 of that of high-density sedimentation tanks, making it ideal for sites with limited land availability.
• Low construction cost

  The total hydraulic retention time is 20–30 minutes. The compact structure significantly cuts civil engineering costs.
• No sludge hardening

  Sludge deposition and hardening never occur inside the tank body and recirculation system.
• Fast startup performance

  Stable operational status can be achieved within an extremely short time (typically less than 15 minutes), suitable for batch treatment conditions with frequent startup and shutdown cycles.
