Deaerator Systems
HEDEF WATER DEGASER SYSTEMS
Deaerator Systems are used to remove dissolved gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S) in water. For the removal of dissolved gases in water; Water enters the unit from the distribution diffuser at the top of the Deaerator. Water filters down by contacting the rings filled in the upper tower of the Deaerator. While it is filtering downwards, the air provided by the Deaerator fan is given from bottom to top, ensuring that the water comes into contact with the air. Air absorbs the dissolved gases in the water and blows them away. Thus, the gases in the water are removed with the reverse flow principle and the purified water is stored at the bottom of the Deaerator.
DEGASTING SYSTEMS
Deaerator systems relieve the burden on ion exchange systems by removing both naturally occurring gases and gases formed as byproducts at various stages of water treatment. These simple and economical systems do not require any maintenance, and when used, the frequency of resin regeneration is significantly reduced.
FORCED DRAFT CARBON DIOXIDE REMOVERS
It consists of an atmospheric deaerator tank filled with plastic material. Process water is sprayed onto this filling material from above, so that the water slowly disperses and releases the carbon dioxide it contains. The released gas is discharged through a low pressure fan through a ventilation neck located at the top of the tank. Process water is collected in a tank that forms the lower part of the unit and passes to the next stage of treatment.
WHEN ARE THESE UNITS NEEDED?
Forced-blow carbon dioxide deaerators remove most gases, especially carbon dioxide, from the process water and are typically used between cationic and anionic ion exchange units or after the RO unit. If the carbon dioxide level of the process water is high; Not using a CO2 deaerator; It causes the regeneration process of the anionic resin to become more frequent, waste of time and excessive chemical consumption. Carbon dioxide is a byproduct of the cation exchange process and pH control using various acids.
