This study aimed to investigate the efficiency of Chaetomorpha algae in treating wastewater and oil-contaminated seawater. The experiment was conducted by cultivating Chaetomorpha algae in controlled seawater conditions and exposing them to different types of pollutants. Four experimental treatments were established: (1) a control group containing only seawater, (2) seawater mixed with synthetic wastewater, (3) seawater contaminated with engine oil, and (4) seawater containing both synthetic wastewater and engine oil. Each treatment was performed in triplicate to ensure experimental reliability.
The efficiency of Chaetomorpha algae in water treatment was evaluated by observing changes in water quality parameters and the growth response of the algae throughout the experimental period. The results of this study are expected to demonstrate the potential of Chaetomorpha algae as a natural and environmentally friendly biological agent for the remediation of wastewater and oil pollution in marine environments. This research provides fundamental information that may contribute to the development of sustainable bioremediation approaches for coastal and marine pollution management.
