The Difference Between BOD and COD in Water Treatment

Have you ever wondered how water treatment facilities manage to clean our water so effectively? At the heart of this process are two critical measurements: BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand). These are essential in determining the quality of water and its suitability for use. Understanding the difference between these two can […]

Understanding the Ecological Effects of Wastewater Discharge

Wastewater discharge has significant impacts on aquatic ecosystems, affecting the water quality, biodiversity, and overall ecological balance. When untreated or poorly treated wastewater is released into water bodies, it introduces a variety of pollutants such as nutrients, pathogens, heavy metals, and organic compounds. These pollutants can lead to eutrophication, a process where excessive nutrients cause
