Chemical Cost Comparison of a Conventional Deaerator vs a Liqui-Cel® Membrane Contactor System

Mixed bed ion exchange is often used to polish reverse osmosis (RO) permeate in many industrial water systems.

This process has been utilised for several years and it is well known that the management of the dissolved carbon dioxide (CO2) in the water is critical for an efficient operation.

Membrane systems also have additional value added benefits to consider. The membrane acts as a barrier between the gas and liquid phase. This prevents particles and other contaminants in the air from contaminating the RO permeate.

This is especially important in an environment where a deaerator may not be practical due to ambient air contamination. The membrane system is also modular and can be easily expanded to meet plant water demand growth.
