QCF Efficient Air Flotation Wastewater Treatment Machine
In the treatment process of water supply and drainage ,solid and liquid separation technology and equipment is one of the key items. Specific gravity close to the water, the removal of small suspended solids ,flotation is one of the most effective methods.
The device is widely used in water supply and drainage treatment works. First applied to the lake as the source of the water plant algaecide turbidity; second ,used in industrial sewage treatment works, such as petrochemical ,textile, printing and dyeing ,electroplating , tanning , food industry and other fields; applied sewage recovery of useful material ,such as :paper, pulp water recycled fiber and other fields.
- The effective depth is 600 to 750mm
- Pool hydraulic retention time is short (5 to 10 min)
- Purification capacity ,high surface load
- Installation and maintenance in low cost ,easy to clean
- The high degree of purification , algae and other suspended solids removal rate is more than 90% ; the concentrated sludge concentration is up to 35%
- The device uses the FA-Dissolved air system ,it is ingenious structure, dissolved air efficiency up to 90% , the volume is only one-fifth of the general dissolved air system , with the super strong ability of the anti-clogging.
3. STRUCTURE AND WORKING PROCESS
The floatation separation technology explanation: The air and water in a certain working pressure, the air dissolved in water, and strive to become saturated, and then release/decrease the pressure of the air dissolved water, it produce a large number of micro air bubbles. The micro air bubbles fully contact the suspended particles in the water, the suspended particles adhere to the bubbles, float up to the surface, and then become scum. The scraper removes the scum. In this way, the water is purified.
QCF efficient Air Floatation device is an advanced rapid flotation system. It based on the traditional flotation, and successfully applied the principle of “shallow theory” and “zero speed”. It integrates flocculation, flotation, skimming, scraping functions. It is a high efficient equipment for water purification.
Against the shortage of traditional flotation tank, QCF efficient Air Flotation device change the design. Its raw water flow-in outlet designed to be mobile, to shorten the raw water bubbles floating time. When the raw water flows to the flotation tank, the water outlet is moving to the opposite direction of raw water flow. In this way, the raw water in the pond is in a relatively static status, so the bubbles float along the vertical direction to the surface of the water. The floatation speed is close to the floating speed of the solids in the raw water (4 to 10 cm/min).
Suspended solids in raw material can quickly float to the surface, while purified water under the scum keep unmoved, clean water can be discharged to the pool when the water collect pipes arrive. In order to make the water inlet and outlet to move synchronously, the device is designed into a round shape, the water inlet and outlet is installed on a round turning fixture, making it turning around the center. This moving water distribution creates the “zero speed”. The suspended solids in the raw material can quickly float to the surface, in the three minutes, the raw water can reach the purification requirements.
The device as a whole is cylindrical, compact. The pond is shallow. It includes the pond, the spiral water distribution system, dissolved air release system, rotating fixture, clean water collect system, skimming system, dissolved air system, return water pipe and electronic control cabinet. This device provides complete sets of equipment and control systems, centralized control and decentralized control combined to make the device to operate optimally.
