    High performance coagulation-sedimentation column

    Product Review:

    The column is designed with a unique internal structure that promotes thorough reaction and stratification of wastewater and chemical solutions.

    Treated water is discharged from the upper section of column into the clean water tank, while concentrated sediment is accumulated in the bottom conical section. An automatic valve at column bottom opens and closes depending on the sludge level, ensuring sufficient reaction time for the wastewater inside and a stable supply of clean water at the outlet. Treated water can be directly recycled back into the production process. Sludge from the column bottom is discharged into a special sludge mixing basin. The unit is distinguished by its compact design, smaller size than analogous units, but with high performance and versatility of use. It is featured with high cleaning rates, can operate in automatic and continuous mode, and is easy to operate, install and maintain, while offering the user a number of advantages.

    Product Advantages

    The column height and diameter are designed based on the residence time required for your specific wastewater. Highly precision internal baffles prevent mixing of purified water with sediment. Our technological solutions ensure a compact and mobile installation, guaranteeing consistent water clarity.

    FAQ

    What makes the coagulation column design unique compared to conventional mixers?

    The column combines rapid mixing, flocculation, and primary sedimentation processes in a single vertical vessel. Directed flow and the creation of zones of varying turbulence distribute the coagulant with maximum efficiency. This allows for the formation of large, heavy floccules that settle several times faster than in standard trays.

    Does the column reduce chemical consumption

    Yes, thanks to optimized hydrodynamics, the contact time between the reagent and water is increased, eliminating "dead zones." This allows for a 10-20% reduction in coagulant dosage while maintaining high water clarification quality. For large-scale production facilities in Tashkent, these savings significantly reduce operating costs for water treatment.

    How is the accumulated sludge removed from the bottom of the column?

    The bottom section is conical, allowing for natural sediment accumulation. An automatic discharge valve opens in response to a timer or turbidity sensor, removing the sludge without interrupting the main cleaning process. The vertical design saves space in the workshop and simplifies piping.
