Micro Nano Bubble Air Flotation Device

Brief Introduction Of Micro-nano Air Flotation Device

The micro-nano air flotation oil removal device is a new type of air flotation oil treatment equipment. It works by using pressurized dissolved gas and subsequent pressure release to generate uniform micro-nano bubbles. Under the action of these micro-nano bubbles, oil and suspended solids are separated from the water. The device mainly consists of a micro-nano air flotation unit and an air flotation clarification tank, and its main components include a motor, pump, dissolved gas tank, pressure gauge, safety valve, and clarification tank.

Features Of Micro-nano Air Flotation Device

• It is compact structure and a small footprint.
• The micro-nano bubbles are small and uniform in size.
• It is easy to install, simple to operate, and easy to master.
•  It features advanced technology, a reasonable design, and low operating costs.

Working Principle Of Micro-nano Air Flotation Device



The micro-nano bubble dissolved air flotation oil removal device works by pressurizing wastewater with a water pump, while simultaneously injecting air before the pump.  In the dissolved air tank, the air dissolves into the wastewater. Then, a pressure reducing valve releases the dissolved air, generating a large number of uniformly dispersed micro-nano bubbles. These micro-nano bubbles collide with and adhere to emulsified oil and small suspended particles in the wastewater. The attached pollutants, driven by the bubbles, float to the surface of the treated water, thus achieving the separation of oil and suspended solids from the water.

Liquid-liquid extraction is a widely used separation and purification process for target substances, extensively applied in hydrometallurgy, wet-process phosphoric acid production, chemical and pharmaceutical industries, and environmental protection. In industrial production processes, the raffinate, wash water, and back-extraction liquid (aqueous phase) generated during the extraction process often contain a certain amount of extractant (oil phase).  Depending on the system and operating conditions, the oil content in the water can range from tens to hundreds of ppm. If this oil is not further separated, it will not only lead to extractant loss but also affect product quality. Micro-/Nano-bubble flotation (MNF) is a very effective technology for deep oil removal and clarification, especially suitable for systems with low oil content (tens to hundreds of ppm), small oil droplet size, and high degree of emulsification. Typical Application Fields of Micro- and Nanobubble Flotation:

✅ 1. Hydrometallurgy
• Copper / Nickel / Cobalt / Lithium / Rare Earth Elements / Zinc
• Extraction systems such as P204, P507, Cyanex, D2EHPA, etc.
• Particularly suitable for high-acidity, high-salinity aqueous phases
✅ 2. Wet Process Phosphoric Acid and Phosphorus Chemical Industry
• Purification of phosphoric acid by extraction
• Removal of entrained TOPO, TBP, and amine extractants
• Reduction of organic matter entering the evaporation system
✅ 3. Chemical and Fine Chemical Industry
• Organic acid, phenol, and amine extraction processes
• Clarification of intermediate back-extraction liquid
• Pre-treatment of high-COD, low-oil wastewater
✅ 4. Pharmaceutical and Biochemical Industry
• API extraction and solvent recovery sections
• Strong adaptability to emulsified systems
• Does not damage heat-sensitive substances
✅ 5. Environmental Protection and Wastewater Treatment
• Deep oil removal from extraction wastewater
• Used as:Pre-treatment before biochemical treatmento Protection unit before membrane systems (UF/RO)
• Reduces membrane fouling and foaming problems

Micro- and nano bubble flotation equipment is very suitable as a "fine oil removal unit" for the aqueous phase in liquid-liquid extraction processes. It can achieve efficient solvent recovery and aqueous phase purification under low oil content and strong emulsification conditions, and is becoming an increasingly important supporting equipment in hydrometallurgy, phosphorus chemical industry, and high-end chemical extraction processes.
