Summary
Product Identification
This document describes the application of 3M™ Liqui-Cel™ Membrane Contactors in a power plant in Thailand to remove CO₂ from water. The system utilizes one 14-inch membrane contactor.

General Application
3M™ Liqui-Cel™ Membrane Contactors remove dissolved CO₂ from water, particularly benefiting Electrodeionization (EDI) systems by reducing the ionic load and improving water quality. The contactors prevent air-to-water contamination by using a hydrophobic membrane with 0.03 µm pores, which is a key advantage over forced draft deaerators. This mechanical removal of CO₂ reduces the need for chemicals and pH adjustment.
