Scientists in Canada is developing a fascinating way to sense when water is contaminated. Their box, called the FRED or Field Ready Electrochemical Detector, contains “tunable” bacteria that react in the presence of unwanted substances.
Spherification is a fun way to produce edible containers for water or other liquids. It isn’t difficult to do. Appliance Science shows you how to spherify water and other liquids.
A child dies every minute from a waterborne disease, and he or she most likely lives in sub-Saharan Africa. Millions of people in the region don’t have access to clean water and thus face the risk of diarrhoea or other deadly water-related diseases.
Roughly one-fifth of public water supply in the United States goes to the commercial and industrial sector, or 80 billion gallons per day. APANA customers have demonstrated an average 20 percent savings in water use, and average payback on capital expenditure of 18 months.
A University of Wyoming professor has made a discovery that answers a nearly 100-year-old question about water movement, with implications for agriculture, hydrology, climate science and other fields.
The device is a small plastic canister that attaches to a battery with what look like miniature jumper cables. Using a special “brine bottle,” you add salt and water in amounts indicated by lines. Mix it up, and add the salt solution to the SE200. With the push of a button, the canister illuminates, and the solution begins to bubble.
Recently, a new well, reservoir and arsenic treatment system were installed for the Mesquite Hills subdivision through a public/private partnership between the City and VRE Cottonwood LLC. This new system has the capability of removing arsenic from the backwash water before it is discharged to the sewer system.
From August to December 2014, air conditioners at six gates produced more than 5,200 gallons of condensate, according to the San Diego County Airport Authority, which runs Lindbergh Field. This month, air conditioners at two more gates were added to the collection program for a total of eight.
It weighs no more than 300 grams, fits easily into a backpack and looks like any other plastic bag. But the simple device is a life-saver for people who have no access to clean drinking water. The bag, called Fieldtrate Lite, filters dirty water, such as river water, through a membrane and turns it into potable water in the same time it would take to run it from the tap.
Environmentalists continue to fight desalination because they say that pumping ocean water and disposing of the concentrated brine harms sea life. Desalination plants also use a lot of energy.
The textile industry has long been one of China’s largest polluters. One Chinese government estimate puts the amount of shallow and deep groundwater that is severely polluted in the North China plains, home to a significant portion of China’s farmlands, at more than 70%.
Lack of potable water is a huge problem in many developing countries. According to UNICEF, 783 million people worldwide are without improved drinking water, and the World Health Organization estimates that lack of proper drinking water causes 1.6 million deaths each year from diarrheal and parasitic diseases.
