How many flotation zones do shallow flotation machines usually include?

1. Single flotation zone: Some shallow flotation machines include only one flotation zone, where suspended matter in the water is separated and floated in a single zone by the action of flotation bubbles. This configuration is suitable for smaller treatment needs and limited space.
2. Multiple flotation zones: Larger shallow flotation machines usually include multiple flotation zones, each of which can be operated individually or in sequence to increase separation efficiency. Different zones may have different depths and treatment capacities.
3. Series flotation units: In some configurations, flotation units can be connected in series so that water is treated in multiple units in sequence to further increase the separation efficiency of suspended matter.
Each flotation zone usually includes a gas injection device to form bubbles in the water to help suspended matter float to the surface of the water and be collected and removed by a flotation plate or overflow device.
The specific flotation zone configuration usually varies depending on the treatment needs, water quality characteristics, equipment design and manufacturer's specifications. For a specific water treatment project, it is important to select the appropriate number of flotation zones to ensure the required water quality and separation efficiency. If you have specific water treatment needs, it is recommended to work with the equipment manufacturer or supplier to obtain recommendations for the best configuration for your application.
