    Air flotation and sedimentation equipment

    Product Review:

    A combination of physical and chemical methods are applied in unit, integrating traditional advanced processes such as chemical treatment, dissolved air flotation and filtration adsorption. The process is simple, practical and widely implemented. Equipment is featured by adaptability, compact design, easy for transportation and installation, simple operation, stable and reliable performance. It shows excellent results when separating water and solid phases as well as effectively removing suspended solid particles.

    Integrated air flotation and sedimentation plants are widely used in various industries such as engineering, chemical, textile, transportation and food, wastewater treatment.

    Equipment advantages:

    It is cost effective due to low power consumption, automatic sediment discharge, quiet operation and simplicity of operation.
    It can effectively remove a large portion of insoluble COD and floating solid particles (with lower than water density) as well as settled particles (with density higher than water) from wastewater, and the energy consumption is only 1/8-1/10 of normal air flotation.
    System can effectively remove fats, colloids and suspended solid particles from wastewater, reducing BOD, COD, suspended solids and other pollutants, significantly improving water quality.

    Product Advantages

    Combined flotation and sedimentation zone design is calculated based on the specific contaminant density of your wastewater. Highly accurate flow separation eliminates sludge carryover into the clean water line. These technological solutions significantly reduce the footprint of treatment facilities, guaranteeing comprehensive treatment of complex, multi-component wastewater.

    FAQ

    What is the advantage of combining flotation and sedimentation in a single unit?

    This unit combines two purification methods: heavy particles settle to the bottom, while light impurities (fats, oil products) rise to the surface in air bubbles. This approach allows for the effective treatment of wastewater with mixed contaminants, which is common in Tashkent's multi-industrial zones. You save space and money by replacing two separate units with a single combined unit.

    How does the system for removing two types of sludge from a single tank work?

    The top layer of flotation sludge is removed by a chain scraper mechanism into a special pocket, while the bottom sediment is collected by a lower auger or scraper in a cone-shaped section for pumping. ASMEX PETROCHEM automation synchronizes these processes, preventing re-mixing of the phases and guaranteeing high purity of the clarified water.

    Is it possible to adjust the aeration intensity to changes in the wastewater composition?

    Yes, the control system allows you to adjust the air flow and water recirculation rate. This is important for sudden discharges at the plant, when the concentration of oils or suspended solids increases sharply. Flexible settings help maintain consistent cleaning results without excessive energy consumption or equipment wear.
