Aeration Gas Float Machine

Equipment Introduction:

Aeration flotation is suitable for treating water with low turbidity, high color concentration, high organic matter content, low oil content, low surface active substance content, or algae-rich water. Compared to other aeration flotation methods, it boasts advantages such as high hydraulic load, low investment, small land occupation, high degree of automation, and convenient operation and management. For oil-water separation, suspended solids,COD、BODThe device is highly effective in removing impurities. The entire unit consists of a sewage pump, metering device, reaction tank, flotation tank, flotation system, sand filter, activated carbon absorption column, and an electrical control system, which can be custom-designed according to user requirements. Once the unit is adjusted to normal operation, it can generally run automatically with ease of operation.

Operating Principle:

1Function: Primarily used for solid-liquid or liquid-liquid separation (while also capable of reducing)COD、BODColorimetry, etc.). 

2The air flotation process involves treated wastewater entering the contact zone of the flotation tank, where it is thoroughly mixed with the dissolved air water released. This causes the flocs in the water to adsorb onto the microbubbles, then they enter the separation zone. Under the buoyancy of the microbubbles, the flocs float to the surface, forming a scum layer. The lower clear water flows to the clear water pool via a collecting device and is discharged. Once the scum on the surface accumulates to a certain thickness, it is scraped into the scum槽 by a skimmer and discharged. The settled sludge is discharged through the sludge outlet.

3The generation and release of dissolved air: Clear water or froth water is pressurized by a dissolved air pump and enters the dissolved air tank through a control valve. Under pressurized conditions, air dissolves in the water. When passing through the release device, the dissolved gas experiences a rapid drop in pressure, releasing a large number of finely sized, uniformly granulated, and dense stable microbubbles.

Features of Dissolved Air Flotation Machine:

1Tightly structured for easy hoisting and transportation, installation is convenient.

2Patented dissolved air technology; Dissolved air system efficiency exceeds80％。

3Utilizing a new type of release mechanism, it is less prone to clogging, with a release efficiency up to99Above %. Bubble diameters are all50μmBelow. 

4The equipment comes with its own control box, and after debugging, it can operate normally with full automation. 

5Highly advanced technology, high processing efficiency, low operating costs, and excellent water quality output 

6High processing capacity, high efficiency, and minimal space required. 

7The process and equipment structure are simple, easy to use and maintain. 

8Eliminates sludge expansion. 

9Aeration during the flotation process effectively removes surface-active agents and odors from the water, and simultaneously, the increased dissolved oxygen in the water due to aeration provides favorable conditions for subsequent treatment. 

10For water sources with low temperature, low turbidity, and high algal content, the aeration flotation method can achieve good results. 

Product Applications:

1Remove algae and reduce turbidity from lake and river water for potable and landscape water use. 

2Wastewater pretreatment and sludge thickening. 

3Industrial Water Treatment: Papermaking white water pulp recovery and reuse, dyeing wastewater color and impurity removal, electroplating wastewater heavy metal ion removal, oil refining wastewater and oil separation, leather manufacturing wastewater impurity removal, industrial wastewater treatment for chemicals, food, textiles, garment making, slaughtering, brewing, laundry, etc.
