Desorber is a device that is used in some water treatment installations. It is a non-pressure device consisting of a column (aeration tower) and a tank with appropriate dimensions (matched to individual needs). In some installations where it is not necessary to collect treated water directly at the treatment site, only aeration towers are used, which are plugged into the discharge system of the installation and the treated water is stored in separate tanks or fed directly to the network.
DESCRIPTION OF WORKING
The desorber (aeration tower) uses countercurrent flow of water and air: on the line carrying the medium to the desorber, a spraying nozzle is installed in the upper part of the tower to disperse the water stream over the entire surface of the deposits inside the tower. In counter-current to the flowing water, air moves, which blows the water trapped in the tower's beds. The air flow can be forced (blower) or gravity. The treated water is discharged through a spigot installed in the lower part of the tower to the storage tank or to the installation.
