Shallow air flotation process and separation device
Mar 27,2019
Shallow air flotation is mainly used in the process of micro-second rapid phase separation device. Its device is mainly used to make the two phases of water molecules and air molecules in the dissolved gas water in different directions within less than 1 microsecond. The high-speed motion separates and accumulates in a moment to form a uniform micro-bubble carrying a charge of 3-7 μm in diameter, so that the bubble density increases geometrically under the same conditions of dissolved gas. The integrated charged bubble changes the surface tension of water, adsorbs colored groups and partially hydrophilic colloids, which is a revolutionary breakthrough in purification efficiency. At the same time, the dosage of PAC and PAM is greatly reduced or no need to be added.
Shallow air flotation process
(1) The sewage flows through the trench to the collecting basin to balance the water quality and water volume;
(2) being lifted by a sewage lift pump to a shallow air floatation tank;
(3) The shallow air-floating sewage enters the nozzle and is added with PAC and PAM, and is fully mixed by the mixing tube at the bottom of the air-floating tank, and then mixed with the positively charged micro-bubbles generated by the dissolved gas system to make the micro-bubbles and flocs and waste water The pollutants are adsorbed and bridged into the air flotation water system.
The shallow air float passes through the water distribution system to make the wastewater enter the air floating pool body, and the waste water entering the air floating pool reaches zero velocity in the water distribution area and the air floating area through the air floating water distribution system and the stepless speed regulation device during use. www.khnwatertreatment.com
