Microorganisms and Biotechnology: A Sustainable Alternative

Wastewater generated from industrial production processes is often complex, containing various types of contaminants such as organic matter, chemicals, heavy metals, and oils. Without proper treatment, these pollutants can pose serious risks to the environment and human health. Traditional treatment methods, including chemical precipitation and physical systems, may offer limited efficiency and can be costly.

Biotechnology and the use of microorganisms present a promising alternative for industrial wastewater management. These biological processes naturally break down organic and chemical contaminants, reducing chemical use and promoting long-term sustainability.

How Microorganisms Work in Wastewater Treatment

Microorganisms commonly used in wastewater treatment include bacteria, fungi, and yeast. They are capable of breaking down organic compounds and various pollutants. Their mechanisms generally fall into two categories:

Aerobic Decomposition: Microorganisms use oxygen to degrade organic matter such as fats, oils, and proteins, converting them into carbon dioxide, water, and energy. This effectively reduces BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand). Example: Treatment of wastewater from food and beverage factories.
Anaerobic Decomposition: In oxygen-free environments, microorganisms break down organic compounds into methane and carbon dioxide, which can be reused as renewable energy. Example: Treatment of wastewater from ethanol production and meat processing plants.

Types of Microorganisms Used in Wastewater Treatment

Bacteria: e.g., Pseudomonas spp., Bacillus spp., Nitrosomonas spp. Effective in breaking down organic matter and nitrogenous compounds.
Fungi: e.g., Trichoderma spp., Aspergillus spp. Capable of degrading complex organic materials like cellulose and lignin.
Yeasts: Known for absorbing heavy metals and toxins, ideal for electronic and metal-plating wastewater.

While biological treatment generally leaves no harmful residues and is environmentally friendly, it is sensitive to changes in temperature, oxygen levels, and the presence of industrial chemicals.
