Which Industrial Wastewater is Suitable for Treatment with a Dissolved Air Flotation Unit?

News 2024年3月11日 113

With the increasingly stringent environmental regulations, industrial wastewater treatment technology is continually evolving. Among them, the dissolved air flotation (DAF) unit, as an efficient wastewater treatment equipment, has been widely used in many industries. So, which industrial wastewaters are suitable for treatment with a DAF unit?

I. What is a Dissolved Air Flotation (DAF) Unit?

A dissolved air flotation unit is a wastewater treatment device that utilizes the buoyancy generated by air bubbles to separate suspended solid particles from water. By introducing air into the water, it forms bubbles that collide with suspended solid particles in the wastewater, causing the particles to adhere to the bubbles, forming a floating scum, and thereby achieving the separation of suspended solid particles from water.

II.Which Industrial Wastewaters are Suitable for Treatment with a DAF Unit?

Papermaking Wastewater Treatment

The papermaking industry generates a large amount of wastewater containing suspended solids, colloidal substances, and oils. DAF units can use bubble generation to float these pollutants to the water surface, which can then be treated with other equipment to purify the water quality.

Food Processing Wastewater Treatment

Food processing generates a significant amount of wastewater containing suspended solids, oils, and proteins. DAF units can float these pollutants to the water surface using bubble generation, allowing for further treatment with other equipment to achieve water purification.

Textile Dyeing and Printing Wastewater Treatment

The textile dyeing and printing industry produces a substantial amount of wastewater containing suspended solids, dye pigments, and oils. DAF units can float these pollutants to the water surface using bubble generation, facilitating subsequent treatment with other equipment to purify the water quality.

Petrochemical Wastewater Treatment

The petrochemical industry generates a considerable amount of wastewater containing suspended solids, oily substances, and chemical additives. DAF units can float these pollutants to the water surface using bubble generation, enabling further treatment with other equipment to purify the water quality.

DAF units, as efficient wastewater treatment equipment, are suitable for treating various industrial wastewaters. However, the nature of wastewater varies across different industries, so the selection of DAF units should be based on specific circumstances.
