Abstract
Phycoremediation and bioremediation, employing microorganisms like microalgae, are crucial techniques for wastewater treatment. This study assessed the efficacy of Lyngbya sp., Tribonema sp., and Scenedesmus sp. in refining refinery wastewater naturally. Parameters such as pH, Total Soluble Solids (TSS), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Oil and Grease (O&G), Phenol, Sulphates (SO4), Sulfur (S), Chlorine (Cl), and Total Dissolved Solid (TDS) were meticulously analyzed using American Public Health Association (APHA) methods. Field testing was conducted during spring and autumn over three consecutive weeks. Results revealed promising performance by all three species, with Scenedesmus sp. excelling in the third week, particularly in pH (7.26), TSS (6.87), BOD (4.36), COD (9.71), O&G (0.37), Phenol (0.02), SO4 (162), S2 (0.01), Cl (155), and TDS (154) (ppm). Notably, TDS reached its lowest in the first week (106 ppm). In summary, this study emphasizes the potential of these indigenous species for enhancing wastewater quality, particularly before discharge into the environment or use in irrigation. These findings suggest that these microalgae can be effectively utilized, either individually or in combination, for wastewater treatment applications.
