SWT AP 17-20/D90 aeration pipe
D90 aerator, AP 17-20 size
The SWT aeration pipe is designed for pressurized aeration of water in systems for removing iron, manganese, and hydrogen sulfide. It is installed ahead of filters with granular media: the water becomes saturated with oxygen from the air, the dissolved impurities are oxidized, and are then retained by the filter medium.
Air is supplied ahead of the aerator by oil-free compressors, whose operation is controlled by a separate control unit. Both functions — saturating the water with oxygen and separating excess air — are combined in a single device, so this scheme does not need a separate contact column. The size is selected based on the pipe diameter and the flow rate of the line into which the aerator is tapped.
Design with D90 pipe housing (AP 17-20 size). Dimensions (L×W×H) 1510×380×200 mm. Weight 15 kg.
The smallest unit in the line by weight: 15 kg against 22 kg on AP 30-40.
One step up by weight — AP 30-40: pipe diameter D110 instead of D90, size AP 30-40 instead of AP 17-20, dimensions 1560×430×220 mm instead of 1510×380×200 mm.
