Wastewater with high organic content is one of the major challenges in protecting the environment and public health. Organic substances, commonly found in wastewater from food processing, textile, and agricultural processing industries, can cause severe water pollution if not treated properly. Biological, chemical, and mechanical treatment methods are widely applied to minimize the impact of these wastes. Choosing the right treatment approach not only helps improve water quality but also contributes to resource conservation and environmental protection.
Wastewater with high organic content typically originates from industries such as food processing, textile manufacturing, paper production, livestock farming, and agricultural processing facilities. This type of wastewater contains large amounts of organic compounds such as proteins, carbohydrates, lipids, and other complex organic substances. If not treated promptly, it can seriously pollute water bodies, reduce water quality, and threaten aquatic life. Therefore, treating wastewater with high organic content is an urgent requirement to minimize negative impacts on the environment and human health.
A typical characteristic of this wastewater is the high concentration of organic pollutants (such as BOD and COD), which promotes rapid microbial growth and consumes dissolved oxygen in water. This can lead to oxygen depletion, causing localized environmental stress and death of aquatic organisms. Thus, applying effective treatment solutions is necessary to maintain ecological balance and ensure water quality in the surrounding area.

To accurately assess the quality of wastewater with high organic content, it is necessary to consider various parameters that reflect pollution levels and treatment conditions. pH is an important factor as it affects chemical reactions and microbial activity during treatment. Turbidity indicates the presence of suspended solids and decomposing organic matter, while color shows the extent of organic breakdown or dissolved metals in the water.
The total solids content can influence sedimentation and treatment efficiency, whereas dissolved oxygen (DO) plays a vital role in maintaining aerobic microbial processes. Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) are two key parameters used to evaluate the concentration of organic substances; high COD and BOD values suggest heavy organic pollution and a need for appropriate treatment measures.
Additionally, the levels of nitrogen and phosphorus must be monitored, as high concentrations can lead to nutrient pollution and eutrophication. Finally, microbial indicators, such as the presence of E. coli, help determine whether the wastewater poses potential health risks and ensure safety when water is discharged or reused.
Treating wastewater with high organic load requires applying appropriate and effective technologies to ensure discharge standards are met before release into the environment. Various treatment approaches are applied depending on wastewater characteristics and level of contamination.
Summary of current methods for treating wastewater containing high organic matter
Biological treatment relies on microorganisms to break down organic matter into simpler, harmless compounds such as CO₂ and H₂O. This method is widely used due to its high efficiency and cost savings when operated properly.
The Fenton method uses a reaction between hydrogen peroxide (H₂O₂) and ferrous ions (Fe²⁺) to generate strong oxidizing hydroxyl radicals capable of decomposing complex organic compounds. This method is particularly effective for treating industrial wastewater with high levels of persistent organic pollutants.
Chemical treatment utilizes oxidation, reduction, or neutralization reactions to eliminate pollutants. Chemical oxidants such as chlorine, ozone, or other strong agents can break down organic substances effectively, especially in industries requiring strict discharge standards.
Treating wastewater with high organic content plays a vital role in protecting environmental quality and public health. Biological, Fenton, and chemical treatment methods each provide advantages and specific applications depending on the contamination level. Choosing a suitable method helps reduce environmental impact, optimize treatment efficiency, and conserve resources. Therefore, implementing effective treatment technologies is essential to maintain clean and safe water for humans and aquatic life.
