Poly and Perfluoroalkyl PFAs Substances

Per- and polyfluoroalkyl substances (PFAS) are a set of substances that have been used since the 1940s in various industrial applications like paper making, textile mills, electroplating, firefighting foams and in consumer products like non-stick cookware, stain repellent clothing, food contact materials, paints, cosmetics, detergents and other cleaning products. The term ‘PFAS’ is accepted as the overarching term for the entire class of these synthetic compounds. There are more than 9000 known PFAS compounds, but the global regulation list covers less than 50 compounds. Out of these many PFAS compounds,…

Deionized Water

In precision-driven industries where quality is non-negotiable, deionized water plays a vital role. Unlike readily available tap water, it undergoes a rigorous purification process, removing dissolved minerals and salts to achieve exceptional purity. This meticulously treated water supports diverse industries, enabling manufacturers to produce cutting-edge technologies and safeguard product integrity. Here are three interesting insights on the unique properties of deionized water: Deionized water is water that has been stripped of its conductive constituents, rendering it electrically neutral and chemically inert. This is achieved by running water through ion exchange…

Clamp on Ultrasonic Flow Measurement

Polluted water from motorways and highways is a significant environmental concern, contributing to the degradation of aquatic ecosystems and posing risks to human health. When vehicles travel on these roads, they deposit various pollutants such as oil, heavy metals, and tyre particles. Rainwater washes these contaminants into nearby waterways, resulting in polluted runoff. This runoff can then lead to the deterioration of water quality, harm aquatic life, and disrupt natural habitats. Clamp-on ultrasonic flow measurement – an innovative solution One innovative solution to monitor and manage this runoff is clamp-on…

Grey Water Management and Natural Purification Processes

IntroductionGrey water refers to the wastewater generated from domestic activities, including water from bathrooms, kitchens and laundry. While it is typically contaminated, it is not as hazardous as black water (from toilets). In areas with high population density, such as the Lower Ganges Basin and other river basins, managing grey water presents a significant challenge. This article discusses the natural purification and settlement processes of grey water that exist within local ecosystems. The primary contaminants found in grey water include: Detergents and Surfactants: From laundry and dishwashing soaps, these can…
