The air flotation sewage treatment machine is a newly developed sewage treatment equipment, which improves the sewage treatment effect through new rectification measures. The sewage treatment equipment produced by our company has been widely used in sewage treatment in industry, living area, food, medical treatment, slaughter, bone glue, gelatin, chemical industry, leather, textile, hotel, printing and dyeing, papermaking and other industries.

air flotation machine installation steps:

(1) The electrical box of the dissolved air flotation machine should be placed on the side of the escalator, and the environment should be clean.

(2) Before installing the dissolved air flotation machine, the foundation must be consolidated. Concrete mortar pads 100-150mm high. Overhead installation is also possible, but the foundation must be able to withstand the weight of the equipment in operation.

(3) The clean water outlet can be connected to the sewer discharge outlet. If you need to enter the next treatment process, you can directly connect the next treatment equipment.

(4) After the equipment is in place, the liquid level needs to be adjusted.

(5) The connecting pipeline between the sewage inlet and the reaction tank should be as short as possible to avoid damage to the flocs in the pipeline.

(6) The sludge outlet can be connected to sludge tank or sludge treatment equipment.

(7) The dissolved air flotation machine needs to be equipped with a sewer pipe for cleaning. An open channel can be dug, or it can be directly connected to the adjustment tank through a pipeline, so that the water flushing the air flotation tank can be discharged.

Air flotation machine

Reason for selection:

High-efficiency removal rate of low-density pollutant particles (such as algae, suspended oil, suspended solids that are difficult to settle, etc.).

Clarified wastewater comes from unique dissolved gas and ionic bubble manufacturing technology.

Ultra-high ground load, limited footprint, and intelligent operation.

Application areas:

Low temperature, high turbidity (peak value over 500NTU), high algae, high salinity seawater.

Urban sewage pretreatment, advanced treatment and upgrading projects.

Black and smelly river water, reservoir water, tap water, lake water, algae water, etc.

The working principle of the air flotation machine:

When the micro-flotation technology separates and removes suspended solids and colloidal substances, the micro-bubbles generated by physical methods are attached to the micro-floats and micro-flocs in the treated water, and form "copolymerization" with the intergranular vesicles. The air bubbles form bridging adhesion, and the microflotation is completed by chemical flocculation. Realize solid-liquid separation and purify sewage.

Device Features:

1. The machine is equipped with a dissolved air system, and the average diameter of microbubbles is below 1μm, which is at least 20 times smaller than the current level of 20-50ml. According to the micro-flotation machine manufacturer, in the case of the dissolved phase, etc., the total surface area of the micro-bubble is increased by at least 400 times. In fact, the total surface area, or bubble density, of microbubbles has increased thousands of times due to the large increase in dissolved gas velocity. Studies have shown that when the diameter of the microbubble is less than a certain value, according to statistical mechanics, the impact force of the thermal motion of the surrounding water molecules will be out of balance, and the bubbles will participate in part of the Brownian motion, which is conducive to the diffusion of oxygen molecules in the bubbles into the sewage. Qi effect will be thousands of times higher.

2. The machine adopts a special stainless steel mechanism, which has the effect of rectifying and stabilizing the flow. The special release system eliminates the energy of dissolved gas and water to a large extent, that is to say, the dissolved gas is reduced from the high energy value of the depth balance to almost normal. low energy value of pressure.

3. The equipment is compact in structure, small in size, and occupies a small area: for example, it can process 1000-4000m3 of paper machine white water per day, with a height of only 5.5 meters and an area of 10 square meters, which can be installed in the workshop.

4. The price of the micro flotation machine is reasonable, and the machine consumes less power, which can be reduced by more than 50% compared with ordinary air flotation.

5. Low drug consumption, which can be reduced by more than 50% compared with ordinary air flotation.

6. The removed scum has a high concentration of more than 4%, the effluent is clear and transparent, the removal rate of suspended solids is more than 96%, and the insoluble chemical oxygen demand can be completely removed.
