The aim of this study was to enhance a vertical rotating membrane system that induced gas to liquid mass transfer, and to evaluate its performance by quantifying its inorganic carbon formation rate under different parameters such as carbon dioxide concentration in air, membrane's rotational speed and the composition of the liquid medium. In addition to that, the ability of the zinc plated and nickel wire meshes to catalyze the hydration reaction of carbon dioxide was tested in this study using a bench scale rotating membrane system. The system was enhanced by replacing the mechanism that rotated the mass transfer membrane mesh by a simpler mechanism which depended on rollers to rotate the membrane mesh. Testing the enhanced system indicated that increasing the carbon dioxide concentration from 1% to 2%, from 1% to 10% and from 2% to 10% increased the system’s inorganic carbon formation rate within the ranges of 69%-83%, 385%-521% and 179%-240% respectively. Furthermore, increasing the membrane’s rotational speed from 70 rpm to 90 rpm resulted in increasing the inorganic carbon formation rate within a percentage range of 27%-38%. Also, the tests showed that using BG-11 as a test medium instead of DI water increased the inorganic carbon formation rate within a percentage range of 27%-33.3% when testing the rotating membrane system under 1% and 2% carbon dioxide concentrations respectively. Also, an increase of 7% was noticed when BG-11 medium was used as a medium instead of DI water under 10% carbon dioxide concentration in air. Moreover, results showed that using zinc plated and nickel wire meshes had no impact on catalyzing the carbon dioxide hydration reaction.
