    Dissolved air flotation

    Product Review:

    Flotation plants are basically used for separation of solid and liquid phases. They create many small air bubbles dissolved in water via a special release system. These bubbles bind to solid particles or liquid contaminants in wastewater with a density close to water.
     Due to their floatation, these particles float on the surface, and thereby achieve the solid-liquid separation purpose.

    Application Sphere:

    Flotation machines are used in water treatment for the following applications:

    Removal of suspended solids, algae and other microaggregates from wastewater. Extraction of high value substances from industrial wastewater, e.g. in pulp and paper industry.

    Product Advantages

    The design of the hydraulic saturation circuit ensures maximum water saturation with low energy consumption. Highly accurate flotation cell assembly eliminates turbulence, which interferes with sludge aeration. Microbubble aeration technology guarantees the removal of up to 99% of free fats and suspended solids.

    FAQ

    Why is DAF technology considered the standard for oil product removal?

    The Dissolved Air Flotation (DAF) method creates ultra-fine bubbles that literally envelop particles of emulsified oils and fats. In Uzbekistan's petrochemical production environment, this enables purification levels unachievable with conventional settling tanks or mechanical filters, preparing the water for the biological stage or discharge.

    What role does a saturator play in flotation cell operation?

    A saturator is a unit where air is dissolved in water under high pressure. When this pressure is suddenly released, "white water" of microbubbles is released in the flotation cell's main chamber. We design ASMEX PETROCHEM saturators with corrosion resistance and valve reliability in mind, ensuring uninterrupted system operation 24/7.

    How does automation help reduce coagulant consumption in DAF units?

    The automation monitors the turbidity of the incoming effluent and precisely doses the chemicals before the mixing chamber. This creates stable contaminant flakes that are more easily captured by air bubbles. Optimal dosing not only saves on reagents but also reduces the volume of sludge generated, simplifying its subsequent disposal.
