Water scarcity, flooding, and water pollution are critical water issues in developing countries. Studies have shown that a considerable percentage of diseases affecting third world citizens stem from water inadequacy and poor water quality.
However, with water treatment technologies, there can be a significant improvement in the assessment of drinkable fresh water so that citizens can defeat the health, domestic, and socioeconomic consequences of their water scarcity.
The following ways are how to treat water more efficiently and futuristically:
World Health Organization asserts that 829,000 people die each year from consuming unsafe drinking water. With nanotechnology, we can reduce this menace, as the technology helps to eliminate germs, bacteria, and other harmful elements found in many water supply of the developing nations.
The composite nanoparticles emit silver ions that destroy pollutants. Fortunately, this filter is inexpensive; as such, even the impoverished communities can afford it.
The primary benefits of using nanofilters, unlike conventional systems, include that it only requires lower pressure for water to pass through the filter: although the pores are smaller, the nanotubes have a smooth interior; hence water can pass through more easily.
Besides, they are more efficient and have extensive base surfaces; thus, you can clean it more easily. Nanofilters can remove sediments, bacteria, chemical residues, viruses, and charged particles. They can also eliminate toxic trace elements such as arsenic and viscous liquid impurities such as oil.
2. Smart Monitoring
In developed countries, researchers estimate that about 45 million cubic meters are lost daily by water distribution networks. These leaks aren’t only costly but increase the risk of contaminating the water from the holes in the pipes.
New network surveillance technologies help keep water safe and drinkable, just as it started at the aqueduct. Special pressure gauges and acoustic instruments are connected wirelessly in real-time to an electronic monitoring system that allows water companies to know precisely where the leak is in their network.
3. Reverse Osmosis
Reverse osmosis is also a technique for treating water. This method can filter up to 0.0001 microns. The drinkable water produced by this purification method is referred to as permeate.
A membrane is like a hole through which water for filtration. Reverse osmosis is a technology that uses membranes to filter water. In reverse osmosis, you push the polluted water through the membrane. However, because only clean water can permeate the membrane, you are left with clean water to drink.
Reverse osmosis is presently the best and most prevalent water treatment technology, as it produces water with zero conductivity. It completely removes heavy metals, nitrates, arsenic, pesticides, salts, and all harmful substances. Many islands in the world use this technology to supply water to citizens.
Saudi Arabia has the largest desalination plant globally, with reverse osmosis technology, which produces 50% of the water consumed by citizens.
Although this technology has existed and operated for decades, there is still room to improve its efficiency. Reverse osmosis systems are now sold for home use by water treatment companies.
As mentioned earlier, the most common desalination method is reverse osmosis. However, for this technology to work, it consumes 4-kilowatt hours of energy for every cubic meter of water desalinated.
