Child-education program for the reduction of health risks due to fluoride in water sources in the Chiang Mai Basin, Thailand
Groundwater is the major source of drinking water in Lamphun Province in the Chiang Mai Basin, Thailand. However, groundwater contains high fluoride up to 16 mg F/L, which has caused dental and skeletal fluorosis. Although Thai Government installed RO membrane plants for the removal of fluoride from groundwater; and delivers RO-filtered bottled water that contains less fluoride than the Thai ...

Technology development trajectory for drinking water treatment: a comparative study between South Korea, Thailand, and Lao PDR
This paper reports on a study to compare the technological trajectory of drinking water treatment for the past 30 years, from the 1980s to the 2010s, in South Korea, Thailand, and Lao PDR. There are significant differences in water treatment technology in the three countries, resulting from factors such as national regulations, economic conditions, and water policies. These act either as ...

VSEP takes reverse osmosis where it has never been before, further concentrating RO reject (brine) streams to increase overally recovery to 99%.
Conventional spiral wound membrane systems using reverse osmosis or nano-filtration membranes are increasingly being used to treat well water from underground sources to supplement local drinking water supplies. Many of the remaining underground water sources are 'Brackish' water sources where the dissolved solids can be 5,000 mg/L or even higher. One of the difficult engineering aspects of ...

Using Biological Filtration to Remove Arsenic from Drinking Water
In 2001, the U.S. Environmental Protection Agency changed the standards for arsenic levels in drinking water. At that time, the agency had estimated that more than 36 million Americans were drinking water that contained arsenic levels at or above 3 parts per billion. A new standard was set, lowering the maximum contaminant level to 10 parts per billion (ppb) from the previous standard of 50 ppb. ...
