CDC offers tips to help swimmers stay safe in various swimming venues
When most people think of norovirus, they think of people marooned on a cruise ship with raging stomach and intestinal illness, unable to leave their cabins. However, an outbreak at an Oregon lake underscores that swimming can also put the public at risk of catching the ugly bug. Fortunately, following a few easy and effective steps can help maximize the health benefits of swimming while minimizing the risk of getting sick.
Our bodies of water are constantly sustaining the impact of ecological and environmental changes. Our municipalities are treating water from these sources with harsh chemicals and delivering it to communities. Increasingly aware of these facts, consumers are demanding point-of-use filtration products that ensure that their families are drinking safe, clean water. HaloPure technology was created with these consumers in mind.
NFS is a nanofiltration (NF) membrane formulated to deliver sulfate rejection and flux performance in sulfate removal applications. In addition to exhibiting high mechanical strength and durability, the membrane provides a 30% increase in flux efficiency and more than 99.5% average sulfate rejection when tested under typical seawater operating conditions. This type of NF technology is ideal for enhanced oil recovery during water flooding processes through the prevention of scaling and oil well souring.
AdVantEdge Medallion Series POE systems by AdEdge Technologies are ideal for whole-house arsenic treatment. They require no chemicals and no regeneration for low maintenance, worry-free arsenic removal for the entire household. This economical and effective whole-house treatment employs an adsorption process using Bayoxide E-33 granular ferric oxide to provide the best arsenic removal performance of any available technology, and is considered the standard in the industry.
The research will be done in the university’s Water Quality Center
A group of professors in the Opus College of Engineering at Marquette University has received a $199,679 grant from the National Science Foundation to study drinking water treatment.
The research will be done in Marquette’s Water Quality Center, housed in the college’s Department of Civil, Construction and Environmental Engineering and led by Dr. Brooke Mayer, assistant professor. She will collaborate with Dr. Daniel Zitomer, professor and director of the Water Quality Center, and Dr. Patrick McNamara, assistant professor.
NSF/ANSI 419: Public Drinking Water Equipment Performance – Filtration evaluates the performance of municipal water filtration technologies in removing Cryptosporidium
Global public health organization NSF Intl. published the first consensus-based American National Standard to evaluate the performance of municipal water filtration technologies in removing Cryptosporidium from public drinking water supplies. The new standard—NSF/ANSI 419: Public Drinking Water Equipment Performance – Filtration—incorporates state and federal regulatory requirements, assisting state regulators in verifying compliance while reducing time and costs for manufacturers by streamlining the testing process.
Ball State researchers are studying the impact of human waste on Mount Everest's water resources
Ball State University faculty and students are returning to Mount Everest in May to expand their research into how extensively human waste left by climbers is contaminating water resources on the world’s tallest mountain.
Led by Kirsten Nicholson, a Ball State geological sciences professor, the team will spend several weeks in Nepal to conduct studies as part of the university’s Himalayan Sustainability Initiative.
The H-300-NXT Everpure line of luxury residential water filtration products is certified to NSF/ANSI Standard 401 for the removal of contaminants such as pharmaceuticals, over-the-counter medications and chemical compounds including bisphenol A. The pleated filter membrane is 30% larger than the standard H-300 and provides 50% greater dirt-holding capacity and contaminant reduction capability while maintaining longer filter life. The drinking water system can be installed in kitchens or wet bars and can be connected to appliances.
New facility will help Rwanda's capital city meet current & projected drinking water needs
The Water and Sanitation Corp. Ltd. (WASAC) in Rwanda awarded Culligan Intl. a contract to design and install a water treatment plant to provide drinking water to Kigali, that country’s capital city. WASAC is a government company that provides water to Kigali City and all urban centers of the country.
“Kigali needs about 100,000 cu meters of water per day while water supplied is 65,000 cu meters per day, which implies a shortage of about 35,000 cu meters per day,” said James Sano, CEO of WASAC Eng.
States that make up the Hypoxia Task Force are working together to reduce nutrient levels nearby waterways
The 12 U.S. states of the Hypoxia Task Force have devised new strategies to speed up reduction of nutrient levels in waterways in the Mississippi/Atchafalaya River Basin. High nutrient levels are a key contributor each summer to the large area of low oxygen in the Gulf of Mexico known as a dead zone. Each state has outlined specific actions it will take to reduce nitrogen and phosphorus in the Mississippi/Atchafalaya River Basin from wastewater plants, industries, agriculture and storm water runoff.
