Abstract:
The interaction of phosphorus and nitrogen on their removal by microalgae can be of great concern during their role as bioremediant of waste water. Microalgae play an imperative role in nutrient and heavy metal removal in wastewater by their biosorption mechanisms. The study was attempted to optimize the pH and retention time for nutrient and heavy metal (zinc) removal from aqueous solutions using immobilized marine microalga Chlorella marina as beads and powder. The study inferred that pH 6 was found to optimum for removal of all nutrients except nitrite. However, for heavy metal removal, the pH 8 was found to be suitable for biosorbent studies. Further, the present experiment inferred that the 24 h incubation was enough for nutrients and zinc removal while using immobilized microalga C. marina beads.
