Desorbers, aeration towers


A 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 connected to the discharge system of the installation and the treated water is stored in separate tanks or fed directly to the network.


DESCRIPTION OF FUNCTIONALITY


The desorber (aeration tower) uses a counter-current 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 by 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.


CONSTRUCTION


Desorbers (aeration tower) are entirely made of corrosion-resistant materials: made of stainless steel/acid-resistant and/or synthetic materials. The tower body typically consists of several segments to facilitate disassembly and cleaning of the bed. An observation window allows you to keep track of the cleanliness of the interior of the device.

 

 

EFFECT


- Non-pressure aeration (oxygenation) of water before iron and manganese removal stations
- Removal of dissolved gases from water (e.g. CO2, H2S, NH3)
- Water de-ironing
