Comparative study of phyco-remediation through micro alga for refinery wastewater treatment
Abstract
The use of microorganisms like microalgae in bioremediation and phycoremediation are essential methods for treating wastewater. The effectiveness of Scenedesmus sp., Tribonema sp., and Lyngbya sp. in spontaneously refining refinery wastewater was evaluated in this study. The American Public Health Association (APHA) methods were used to carefully analyze parameters like pH, Chemical Oxygen Demand (COD, Total Soluble Solids (TSS), Oil and Grease (O&G), Biological Oxygen Demand (BOD), Phenol, Sulfur (S), Chlorine (Cl), Total Dissolved Solid (TDS) and Sulphates (SO4). Over the course of three weeks in the spring and fall, field testing was done. Outcomes showed that all three types performed admirably, with Scenedesmus sp. standing out in particular in the 3rd week's TSS (6.87), pH (7.26), COD (9.71), BOD (4.36), O&G (0.37), S2 (0.01), Phenol (0.02), TDS (154) and Cl (155) (ppm) tests. Remarkably, TDS dropped to its bottom point of 106 ppm within the first week. In conclusion, this study highlights how these native plants might improve wastewater quality, especially before it is released into the environment or used for irrigation. These results imply that the microalgae have potential applications in wastewater treatment, both alone and in combination
