Shallow Air Flotation Machine
Applications
Huaneng Jinhao industrial oil water separation equipment is designed as an unpowered piece of filtration equipment that can recycle more than 90% of waste oil for reuse. The high efficiency device minimizes operation costs and helps protect the environment. It is widely used in the oil-water separation of all kinds of mineral oils (with the exception of crude oil), plant oil, and animal oils. This equipment is vital for the treatment of oil sewage from restaurants, industrial facilities, hospitals, schools, garages, and other heavy industrial applications. The industrial oil water separation equipment is designed to solve environmental pollution concerns, sewer blockages, and sewage overflows caused by the solidification of grease during cold periods.
Design principle
The shallow air flotation system is a water quality purification device with high efficiency, and is used to separate and remove very small suspended solids whose density is similar to the water. The principle of the air flotation method is in the follows: Firstly, the air dissolving system produces the air dissolving water, the dissolving water releases into the water and produces many very small bubbles after rapid decompression. Secondly, the numerous small bubbles adhere to the surface of the flocculation particle, form the suspended solids whose integrated density is less than 1, and the new forming suspended solids rises to the water surface. Thus realizing the solid-liquor separation.

Main structures of the shallow air flotation system
The main structures of the shallow air flotation system includes the pond structure, skimmer, service bridge, under carriage, water and air distributing device, water collection device and control system.
Feature of the shallow air flotation system
(1) Light weight; Compact structure; convenient transportation and installation; energy efficient;
(2) High automation; operating easily;
(3) High efficiency; the stop time is as short as 3 to 5 minutes;
(4) The shallow air flotation system uses the theory of "zero speed", forcing the water distribution and water in and out maintain a static state, thus making the least disturbance to the floccules in water. The scum is removed immediately and the machine has high stability.
(5) The machine uses the " Shallow precipitation theory ". And the effective pond depth is only about 400 to 600 mm, the occupied area of the machine is small.
