Product Description

Micro-nano flotation technology is a solid-liquid separation technology based on micro-nano bubbles. This technology generates a large number of micro-nano bubbles in water through specific equipment and methods. These micro-nano bubbles have a high surface area to volume ratio and can more efficiently attach to suspended matter, grease and other pollutants in the water, thereby bringing them out of the water surface and achieving solid-liquid separation.


Technical advantages
Improve the removal rate of suspended matter: Micro-nano flotation technology can generate a large number of micro-nano bubbles, which have extremely high adhesion and can effectively attach to suspended matter in the water. Therefore, compared with traditional flotation technology, micro-nano flotation technology can more efficiently remove suspended matter in water, including fine particles, grease, etc.

Micro-nano flotation technology can not only remove suspended matter in water, but also promote the decomposition of soluble pollutants and remove harmful substances in water through the oxidation of micro-nano bubbles. This comprehensive purification effect makes micro-nano flotation technology perform well in sewage treatment.

Selection parameters
Application scope
1. Heavy metal ions in electroplating wastewater.
2. The COD removal rate of food slaughtering and leather making wastewater is about 70%, and the suspended solids removal rate is about 90%.
3. The oil content in oil refining wastewater can be reduced to below 10mg/l, and the clarity of wastewater can reach the level of chemical wastewater and pigment paint wastewater, with a COD removal rate of about 74% and a chromaticity removal rate of about 93%.
4. The fiber recovery rate of papermaking white water can reach about 95%, the COD removal rate can reach about 86.7%, and the water can be fully reused.
5. The turbidity of large pool bathing water can be stabilized below 10 degrees, the bacteria in the water have decreased significantly, and the turbidity of drinking water and industrial water can be purified to below 5 degrees, which has a good effect on reducing the chromaticity oxygen consumption.
6. The above data are empirical values, for reference only, and the actual effect shall prevail.
