Dr. Saib Jassim delivered a theoretical lecture on water pollution to postgraduate students.

Dr. Saib Jassim Mohammed, a lecturer in the Department of Biotechnology at the College of Applied Sciences, University of Samarra, presented a theoretical lecture on “Water Pollution” to postgraduate students in the department.

During the lecture, Dr. Jassim defined water pollution as one of the most significant challenges facing ecosystems. He emphasized the importance of adopting various treatment methods that are more sustainable and environmentally friendly, such as bioremediation techniques for wastewater treatment. These methods rely on the use of microorganisms, particularly bacteria, to treat contaminated water by breaking down pollutants and converting them into simpler, less harmful compounds.

This approach is widely used in the treatment of wastewater and industrial water due to its efficiency and lower cost compared to chemical and physical treatment methods.

Furthermore, the lecturer highlighted the important role of bacteria in treating industrial wastewater through their metabolic activity, which involves decomposing organic materials and using them as a source of energy. This process results in the production of stable substances such as water, carbon dioxide, and biomass.

In conclusion, Dr. Mohammed discussed the main types of bacterial treatment, including aerobic treatment, which requires oxygen and is characterized by high speed and efficiency in removing pollutants, and anaerobic treatment, which occurs in the absence of oxygen and produces biofuels such as methane gas.
