A degasser tower removes carbon dioxide from water by forcing air through the water from the bottom and allowing the carbon dioxide to escape from the top.

 A degasser tank is a component of a demineralization (DM) plant that stores degasified water: 

Function

A degasser tank collects water that has been freed of carbonic acid and stores it until it is pumped to where it will be used. 

How it works

A degasser tower removes carbon dioxide from water by forcing air through the water from the bottom and allowing the carbon dioxide to escape from the top. The water is then collected in the degasser tank. 

Components

A degasser tower has three main parts:

Tower: Filled with rings to increase the surface area and break up the falling water into small drops 

Blower: Forces air up through the water 

Sump: Stores the degasified water until it is pumped to where it will be used 

Materials

Degasser towers can be made from mild steel, rubber-lined, or fiber-reinforced plastic (FRP) 

Installation

Degassers are installed downstream of the cation unit to reduce the load on the anion unit
