Space: the final frontier of water treatment
Today, there are plenty of methods to track and improve water quality. Yet, the technique that stands out the most comes from space. You guessed it - remote sensing (or satellite imagery). Remote sensing refers to the process of collecting and analyzing information about objects, areas, or phenomena from a distance, typically via satellites. Similarly, satellite imagery has to do with obtaining ...

Top Municipal Water Treatment Methods: Transforming Water Quality for Environmental Compliance in the USA
Water supplies in the U.S. are among the safest in the world. According to the CDC, more than 90% of Americans get tap water from community water systems, which must adhere to strict water quality standards. However, just because the U.S. has safer water supplies than other parts of the world doesn’t mean there isn’t room for improvement and better municipal water treatment methods ...

Compact-Ozone System Series: COSY
Compact Ozone System: For numerous water treatment processes, SEWEC ozone systems of the COSY model series are used, which meet the highest quality standards. The ozone systems of the COSY series are designed for fully automatic operation and can be easily integrated into an existing water treatment system. Consist of all necessary components such as: - Booster pump - Ozone injector - Contact ...

Assessing the impacts of local and imported produce on the public and the environment
European environmental groups have been calling to switch from imported agricultural produce to locally grown produce, citing positive social and economic impacts as well as environmental ones; and especially the benefit of reducing the environmental pollution and greenhouse gas emissions caused by long-distance food transportation. In Israel, in contrast, there have been calls to increase ...

Interview with Pumps Africa Magazine: Solutions To Food Security and Clean Water in Africa
Africa’s water scarcity is not necessarily caused by a physical lack of water. In fact, much of the region is generally considered to suffer from what’s called “economic water scarcity,” which means that investments in water resources and relevant human capacity are not substantial enough to meet water demands in an area where the population does not have the financial ...

Effect of increasing bromide concentration on toxicity in treated drinking water
Research is increasingly indicating the potential chronic health effects of brominated disinfection by-products (DBPs). This is likely to increase with elevated bromide concentrations resulting from the impacts of climate change, projected to include extended periods of drought and the sudden onset of water quality changes. This will demand more rigorous monitoring throughout distribution ...

Advanced Oxidation: Water Treatment Solutions for PFAS, GenX & other Emerging Contaminants
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) ...

Issues of drinking water quality of small scale water services towards climate change
As climate change could impact water quantity and quality, important concerns are related to water quality degradation in small scale water services (SSWS). SSWS using surface waters resources (rivers and lakes) for drinking water production are particularly vulnerable to short term transient events due to their low adaptation capacity and their lack of support and technical knowledge compared to ...

Blue gold: why water is this century’s most important investment frontier?
Currently, about 90% of the U.S. population relies on centralized networks of pipes and huge “mega-facilities” for water treatment and distribution. But due to a lack of proper funding, a general deterioration of this water infrastructure has occurred at a rapid pace, nation-wide. For a growing number of businesses, this means public utility companies are refusing to treat ...

What are Causes of a Manganese Spike in Drinking Water?
We have discussed Manganese in surface water sources and the potential issues when stratification in the water source occurs. The level of dissolved Manganese in surface water i.e., with a reservoir can increase dramatically or ‘spike’ under certain conditions. Our previous blog explored those conditions and the issues which are caused by a manganese increase or ‘spike’. ...

Understanding the impacts of allocation approaches during process‐based life cycle assessment of water treatment chemicals
Chemicals are an important component of advanced water treatment operations not only in terms of economics, but also from an environmental standpoint. Tools such as life cycle assessment (LCA) are useful for estimating the environmental impacts of water treatment operations. At the same time, LCA analysts must manage several fundamental and as yet unresolved methodological challenges, one of ...

Report on carbon sensitive urban water futures
The challenge of supplying water and energy required for food production and development while mitigating climate change and adapting to its consequences has been termed the Energy Water Nexus. Water, energy, greenhouse gas emissions and climate change are interlinked through a series of relationships. The water sector is a significant contributor to greenhouse gas (GHG) emissions through several ...
