YHG1800 Rotary Disk Aerator

Conventional Selection and Configuration Table
The complete appliance performance of the YHG1800-A RDA under the conditions of 50rpm and 4m water depth without baffle plate, guide wall or oxygen pump ( disks interval: 2-3ds/m):

Special Performance
1. The disks of RDA are made of lightweight GFRP with high intensity, which has great working efficiency and long operational life.
2. Deep plug flow depth, strong mixing capacity, liquor can be mixed sufficiently by maintaining a certain velocity.
3. The single disk has a great capacity for oxygenation and drives a long distance for the water flow. As a result the number of units can be reduced accordingly.
4. The effective water depth for oxidation ditch reaches 6.5 meters, which greatly reduces the land occupation.
