Shallow air flotation is an advanced dissolved air flotation technology developed based on the “shallow pool theory” and “zero velocity principle”, mainly used for efficient solid-liquid separation. The core of it is to achieve rapid purification by adsorbing pollutants through microbubbles.
Product Introduction
Shallow air flotation is an advanced and rapid air flotation system. It successfull applied the “shallow theory”and “zero speed” principles on the basis of traditional air flotation theory. The devices are mainly composed of pool, rotary water distribution mechanism, dissolved air release mechanism, frame mechanism, and water collection mechanism. The water inlet, water outlet, and scum discharge outlet are mainly distributed in the pool water body, where water distribution mechanism, water collection mechanism, dissolved air release mechanism and frame mechanism are closely connected, turning around the pool center.
High-efficiency shallow air flotation goes into the mixing reactor in the raw water, coagulant and flocculant are added into the pipe mixing reactor, to form the separable flocculate, and mix it with minimal bubbles (bubblediameter range 5-10um) released by the dissolved air release mechanism. Such minimal bubbles are adhered to the flocs in the sewage, to form the air flotation body with the specific gravity smaller than that ofwater. Oil spill (or scum) is accumulated on the rising surface of the air flotation body, and is then collected byoil (scum) scraper into the oil (scum) collecting tank.
Product Advantages
- High purification level with suspension removal rate over 98%.
- Lightweight, compact structure, convenient for transportation and installation, reducing the power consumption.
- Short retention time, only 3-5 minutes, and high efficiency.
- “Zero speed” principle is used, and the forced water distribution and water intake and discharge are static. Since the disturbance to the flocs in the water body is minimized, the scum is instantaneously removed, thus achieving higher stability.
- High surface load, and large purification quantity.
- “Shallow pool theory” is used, and the effective pool length is only 730mm, indicating small floor space.
- High-efficiency block-free releasing mechanism is used to improve the utilization efficiency of the dissolved-air water, and guarantee the working stability of the air flotation devices.
- With stable handling effect, the electromechanical instruments have realized the integrat-ed control.
