COD stands for Chemical Oxygen Demand. It’s a key measure of water pollution in wastewater. COD shows how much oxygen is needed to break down organic matter in water. COD treatment is crucial for protecting the environment and meeting water quality standards. Treating COD in wastewater involves various methods. These can include physical, chemical, and […]
Water professionals face new challenges as emerging contaminants pose risks to our drinking water supplies. These substances, including PFAS, pharmaceuticals, and microplastics, are not fully regulated yet but may harm human health and ecosystems. Water professionals need to stay informed about emerging contaminants, their potential impacts, and evolving treatment methods to protect public health. Recent […]
Pharmaceutical wastewater is a growing concern for the environment and public health. This type of wastewater comes from drug manufacturing facilities and contains various chemicals used in making medicines. Pharmaceutical manufacturing facilities can be a major source of drugs entering the environment, with some treatment plant effluents having 10 to 1,000 times higher concentrations of pharmaceuticals […]
Ammonia in Wastewater Discharge: Environmental Impacts, Treatment Methods, and Regulatory Frameworks Ammonia, a compound of nitrogen and hydrogen with the formula NH₃, is a significant pollutant in wastewater discharge. Its presence in wastewater originates from various sources, including domestic sewage, industrial effluents, and agricultural runoff. Ammonia poses several environmental and health risks, making its […]
Water quality is crucial for maintaining healthy ecosystems and safeguarding human health. Clean water is essential not only for drinking but also for agriculture, industry, and recreation. Pollution, both natural and human-made, can significantly degrade the quality of our water bodies. One of the main concerns is the presence of pollutants like heavy metals, pesticides, and […]
The Eastern Water Reclamation Facility (EWRF) is a crucial wastewater treatment plant providing significant water reuse and environmental services to the Orlando, Florida, region. Owned and operated by the Orange County Utilities Department, EWRF commenced operations in 1986 to help meet increasing wastewater infrastructure demands stemming from rapid Orlando metro population growth through the second […]
Understanding the role of gray water in wastewater management is crucial for the efficient use of water resources. Graywater, essentially the reuse of domestic wastewater from sinks, showers, and washing machines, can significantly reduce the total volume of wastewater requiring treatment. This sustainable practice not only saves water but also lessens the load on sewage […]
