After PFAS were first detected in regional drinking water supplies, the contamination was traced to landfills used from the 1950s through the early 1970s for the disposal of PFAS manufacturing waste. To begin a path forward, our team is advising state agencies and the communities in the regional...
An apparatus for removing target chemicals from water includes a reaction chamber, a source of an aqueous solution of the target chemicals that can be supplied on demand to the reaction chamber, a timer that times a reaction between the particles and the target chemicals such that a ...
In astudythe first of its kind, the Toxic Substances Hydrology Program of the U.S. Geological Survey looked at vulnerable water sources to determine if chemicals were making it into streams. The study analyzed 139 streams considered as vulnerable for a smattering of chemicals, among which were ...
The chemicals known as PFAS are considered a severe threat to human health. Among other things, they can cause liver damage, cancer, and hormonal disorders. Researchers at the Technical University ...

The ceria could adsorb from 13 μmol g−1 to 33 μmol g−1 of dyes (E102, E124, E133, MO) from water. The hard template method can produce highly porous ceria that could be used in environmental protection. Highlights • Mesoporous cerium oxide with a specific surface area of ...
Point-of-use filters containing granular activated carbon (GAC) are an effective method for removing certain chemicals from water, but their ability to rem... E Paramonova,EL Zerfoss,BE Logan - 《Appl Environ Microbiol》 被引量: 34发表: 2006年 Cyclic characteristics of water thermocline storage...
aWater purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water) but water purification may also be...
The removal of the suspended organic matter is initially carried out by adding coagulating chemicals 1 that may help to coagulate the water. Such products provide an aggregation of suspended particles after a certain time, thus forming larger denser flakes that define a flocculating basin upstream ...
Chloramine, which more than 30% of US cities now use as a disinfectant, is more difficult to remove from water than free chlorine. It can be removed with exactly the same treatment strategies that are used for chlorine, but greater contact time is needed. ...
