UV and ozone disinfection technologies have made significant strides in recent years. These methods use powerful light or gas to kill harmful microorganisms in air, water, and on surfaces. UV light at specific wavelengths can disrupt the DNA of pathogens, making them unable to reproduce or cause infections. New types of UV light show promise […]
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 […]
Ceramic filtration offers a reliable method for purifying water. This technique uses porous ceramic materials to remove contaminants from liquids. Ceramic filters can effectively eliminate bacteria, protozoa, and other harmful microorganisms from water, making it safe to drink. These filters work by trapping particles as water passes through tiny pores in the ceramic material. The pore […]
Sand filtration is a simple yet effective method for cleaning water. It uses layers of sand and gravel to remove dirt and small particles from water. This process has been used for hundreds of years and is still common today. Sand filters work by passing water through beds of sand. As the water moves down, […]
Ultraviolet (UV) disinfection is a powerful method for eliminating harmful microorganisms from surfaces, air, and water. This technology uses specific wavelengths of light to destroy the DNA of bacteria, viruses, and other pathogens. UV disinfection is highly effective at inactivating a wide range of microorganisms, including those responsible for many common illnesses. UV disinfection has gained […]
Activated carbon filtration is a popular method for cleaning water in homes and businesses. This process uses special carbon materials to remove harmful substances from water. Activated carbon filters can effectively reduce certain organic compounds, chlorine, lead, and radon in drinking water. These filters work by attracting and trapping contaminants as water passes through. The […]
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 […]
Biological contaminants can significantly affect health and wellbeing in various environments, from homes to workplaces. They include bacteria, viruses, mold, and allergens that can trigger serious health issues. Understanding these contaminants and how they operate is crucial for maintaining a safe living environment and protecting public health. Many people may not realize the extent of biological […]
Sediments are tiny particles of rock, soil, and organic matter that settle at the bottom of bodies of water. These particles come from various sources, including erosion, decomposition of plants and animals, and human activities. Sediments play a crucial role in shaping landscapes, forming new rocks, and affecting water quality. The movement and deposition of sediments […]
