The failure to provide safe drinking water and adequate sanitation services to all people is perhaps the greatest development failure of the 20th century. The most egregious consequence of this failure is the high rate of mortality among young children from preventable water-related diseases. This paper examines different scenarios of activities in the international water arena and provides three estimates of the overall water-related mortality likely to occur over the next two decades.
Dissolved Solids and Water Purification
To make drinking water palatable, the level of dissolved substances (TDS) can’t be too high, but it also can’t be too low Water quality metrics are needed to ensure that surface and groundwater – common sources of water for human consumption – are free from contaminants and pollutants. The level of dissolved solids, also commonly referred to as total dissolved solids (TDS), is a way of measuring the level of organic and inorganic substances in water. This measure refers to any type of...
Types of Water Treatment Systems
There are different types of water treatment systems, and knowing the difference between them can help you make an informed decision on just what type of treatment you’ll need for your water. There is no best water treatment system that will meet everyone’s needs—each system has its benefits and deficiencies. Here are a few of the most common types of water treatment systems. Water Treatment Systems for Drinking Water There are water treatment systems that will only make water potable without...
Reasons You Should Invest in an Arsenic Water Treatment System
In many areas of the U.S., the element arsenic makes its way into the water supply. This element can have adverse health effects. Although it’s rare that it shows up in large enough concentrations to be fatal, it can still cause problems and should be eliminated. Health Effects Many studies have been done to determine the specific effects of consuming water tainted by arsenic. One of the most common health ailments is lesions. Regularly consuming water with traces of arsenic can cause skin problems. This...
How to Choose the Right Biological Water Filtration System
There are many different biological treatments of water available. They’re all similar in a number of ways, but share key differences in the specific ways the water is filtered. This article is an informative breakdown of all the different biological water treatment systems that are available and how they work. Slow Sand Filtration This system supports the growth and maintenance of microorganisms that eventually become its primary filtering mechanism. Its layers work to get rid of any potential contaminants...
Coagulation and flocculation in the Helsinki drinking water treatment plant
The raw water for Finland’s capital Helsinki is pumped from Lake Päijänne, located approximately 120 km away, via a tunnel to two water treatment plants, where it is treated and purified. This secures sufficient drinking water of excellent quality for around one million people. In the drinking water treatment plant in Vanhakaupunki 18 HYPERCLASSIC® Evolution7 mixers and three CYBERPITCH® mixers made by INVENT have been in operation since July 2017. The current plant was reconstructed in...
