Biosolids management has come a long way in recent years. These treated wastewater products can be used as fertilizer for crops and forests. Biosolids improve soil structure by binding soil particles together, creating stable soil with good physical properties. New ways to use biosolids are being developed all the time. Some farms use them to […]
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 […]
Biogas plays a crucial role in sustainable wastewater treatment. It offers a way to clean up sewage while producing renewable energy. This process helps reduce pollution and cuts down on fossil fuel use. Anaerobic digestion in wastewater treatment plants can turn organic waste into useful biogas. This gas is mainly methane, which can be burned […]
PFAS, or “forever chemicals,” pose a major challenge for water treatment facilities. These persistent compounds resist traditional cleaning methods and can harm human health. New approaches are needed to tackle this growing problem. Scientists and engineers are developing innovative ways to remove PFAS from wastewater. Granular activated carbon filtration is emerging as a promising technique […]
Fenton reaction systems are powerful tools in chemistry. They use iron and hydrogen peroxide to create highly reactive molecules. These molecules can break down tough pollutants in water and soil. The Fenton reaction works best at a pH of about 3, which is lower than most natural soil conditions. This means it often needs some […]
Diffused aeration is a critical process commonly used in wastewater treatment and other applications that require efficient oxygen transfer. This technique involves using fine bubbles to introduce air or oxygen into water, promoting effective degradation of organic materials. Understanding how diffused aeration works and its various systems can help industries optimize their operations and enhance […]
Radiological contaminants are substances that emit ionizing radiation, posing potential risks to human health and the environment. These contaminants can come from various sources, including nuclear power plants, medical facilities, and naturally occurring radioactive materials. Exposure to radiological contaminants can lead to serious health effects, ranging from acute radiation sickness to long-term cancer risks. Scientists and […]
Chemical contaminants are substances that can harm our health when they enter our water, air, or food. These pollutants come from many sources, including factories, farms, and everyday household products. They can cause serious health problems if we’re exposed to them over time. Chemical contaminants in drinking water can lead to cancer, organ damage, and […]
Clean water is vital for our health and well-being. Microbial testing of water helps ensure it’s safe to drink and use. This process checks for harmful bacteria, viruses, and other tiny organisms that can make us sick. Microbial testing of water uses special methods to find and count these tiny living things. Some tests look […]
Biological indicators are living organisms that help scientists measure the health of ecosystems. These tiny creatures serve as nature’s own warning system, alerting us to changes in environmental conditions. From bacteria to insects, they provide valuable clues about water quality, soil health, and air pollution. Biological indicators play a crucial role in assessing ecosystem health […]
