How do Carbon Filters Work to Remove Toxic Chemicals in a Drinking Water Supply?
Whether you buy a bottle of water or turn on the faucet at home for a drink, the last thing you want to worry about is that it might be contaminated with bacteria or toxic chemicals. In developed countries and cities that have advanced drinking water treatment facilities set up, they have methods for dealing with those harmful pollutants. It’s the same with bottled water companies. For ...

Effect of advanced oxidation processes on nonylphenol removal with respect to chlorination in drinking water treatment
Any nonylphenol compounds found in water have to be removed since they are endocrine disruptors. In this study, natural water from the river Ebro fortified with nonylphenol compounds (4n-nonylphenol and technical nonylphenol) is used as a sample in order to simulate a real situation in drinking water treatment plants. The aim is to compare conventional disinfection with advanced oxidation ...

Effect of granular activated carbon type and age on quenching H2O2 residuals after UV/H2O2 drinking water treatment
Granular activated carbon (GAC) can be used to quench residual hydrogen peroxide (H2O2) after ultraviolet (UV)-H2O2 advanced oxidation processes in drinking water treatment. Bench- and pilot-scale studies examined the possible loss of GAC reactivity due to continuous exposure to natural water from a water treatment plant in both the presence and absence of H2O2. Six common types of GAC were ...

Quantitative microbial risk assessment of drinking water treated with advanced water treatment process
Campylobacter jejuni is one of the major causes of waterborne disease in Japan. A quantitative microbial risk assessment (QMRA) was conducted to evaluate the health risk caused by this pathogen in drinking water treated with a supposed advanced treatment process including ozonation and granular activated carbon adsorption. Coagulation-sedimentation, rapid sand filtration, ozonation, and ...

What is Potable Water and How is it Treated?
What is potable water?If you can drink it or cook with it, it’s potable. Potable water is classified by the World Health Organization (WHO) as water that is not contaminated with organic, inorganic, radiological, or microbiological pollutants and does not present any differences in taste, smell, or appearance. A majority of the earth’s population has regular and convenient access to potable ...

Combination of up-flow anaerobic sludge blanket reactor and a novel cascade sponge reactor for sewage treatment
Performance of the combined process of up-flow anaerobic sludge blanket (UASB) reactor and cascade sponge reactor (CSR) for sewage treatment was studied. UASB-CSR system was operated at HRTs of 24 h, 16 h, and 8 h at an average wastewater temperature of 29°C. It comprises of the most efficient combined process not only for CODT (98.9%), BODT (98.5%), TSS (99.3%), total nitrogen (89.1%), total ...

How Namibia Embraced Potable Water Reuse
The small southern African nation has been pioneering wastewater recycling since the 1960s The southern African country of Namibia, known for its wide, expansive desert landscapes, is an arid country prone to drought. Water scarcity is a harsh reality for many of its citizens, including the more than 400,000 residents of the capital city, Windhoek, which is also the hub of Namibia’s ...

Advanced Filtration Media (AFM): Clean Water Market Analysis
Executive Summary This report has been prepared by Entec to provide a market assessment of the application of AFM (Advanced Filtration Media) for potable water treatment. The work has been carried out on behalf of BREWEB, the Environmental Body of the Building Research Establishment and Dryden Aqua Limited, the developers of AFM. AFM is a high quality product that has been developed as a ...

Effect of advanced water treatment on behaviour of residual chlorine and development of chlorine control method in distribution systems
The behaviour of residual chlorine concentration in drinking water treated by the mid-chlorination or the advanced water treatment (AWT) was investigated. The AWT removes dissolved organic matter more than the mid-chlorination, thus the rate of residual chlorine reduction is decreased. The analysis of chlorine concentration data measured by automated continuous monitoring devices revealed that ...

Augmenting Water Supply Systems
Direct use of recycled water to augment urban water supply systems entails pumping water into the distribution system or blending with the conventional supply at the water treatment plant. The recycled water needs to be treated to drinking water standards or better, including advanced treatment processes to remove trace organics and chemicals. The City of Windhoek in ...

GWT: AOP Treatment Solutions that Protect the World from PFAS, GenX and Other Emerging Contaminants in Drinking Water & Wastewater
According to recent data, published by EWG, 110 million Americans could possibly have Perfluoroalkyl and Polyfluoroalkyl substances (PFAS) contaminated drinking water sources. While these chemicals have been in use for many years, the extent of their environmental and human impact is only just beginning to surface. As of March 2020, the Environmental Working Group (EWG) had identified 1,477 ...
