Abstract

This study demonstrates the design and testing of a biofilter system that uses Spirulina algae to dissipate flue gas emissions from industry while producing biomass. In following the urgent call for affordable carbon capture technology, this study approaches Spirulina, an algae that has an economic and environmental appeal because of its high rates of photosynthesis, rapid growth, and its tolerance to extreme conditions, including industrial carbon dioxide (CO₂) levels. The system uses an exhaust fan to cycle flue gas into the biofilter, a bubbling system to maximize gas-liquid interaction, and a series of real-time monitoring using a temperature gauge, pH meter, and CO₂ indicating bellow to maintain optimal algal growth and photosynthetic conditions. Experimental results confirmed the lethality of Spirulina algae demonstrated by the attenuation of CO₂ concentrations from inlet to outlet of the biofilter. The algal culture also showed a steady increase in biomass, demonstrating a transfer from inorganic carbon to organic substance. Spirulina demonstrated CO₂ absorption rates of 11-13%, which was under optimum conditions, and showed a high tolerance to CO₂ levels usually present in industrial emissions. This biomass is an additional economic benefit with different applications such as biofuels, food, fertilizers, and drugs. The study concludes that Spirulina is a promising organism for carbon capture and biomass production in a controlled setup. The compact, sensor-integrated biofilter system effectively simulates industrial conditions conducive to algal growth, suggesting that microalgae-based systems could play a critical role in climate change mitigation. While the current research was conducted in a laboratory environment, future efforts will focus on scaling the system for real-world industrial applications and evaluating its long-term efficiency and economic viability.
