        abstract = {Rapid urbanization and the reduction of green spaces have intensified air pollution in major cities. Conventional tree plantation remains an important environmental strategy, but it is difficult to implement in highly congested urban areas where land is limited. Liquid Tree photobioreactors provide an alternative by using microalgae to absorb carbon dioxide and release oxygen within a compact structure. This research evaluates the performance of a conventional cylindrical photobioreactor and an inclined wavy-bottom photobioreactor for urban air purification. A comparative analytical model was developed to estimate carbon dioxide capture, oxygen generation, light utilization, and biomass productivity under identical operating conditions. The study indicates that the wavy-bottom design improves microalgal circulation and creates repeated light-dark exposure, increasing photosynthetic efficiency. The modified reactor achieved approximately 24% higher carbon dioxide absorption, 18% higher oxygen release, and 21% greater biomass yield than the conventional model. These findings suggest that optimized reactor geometry can significantly improve the efficiency of Liquid Tree systems and make them more suitable for deployment in densely populated cities.},
