It is irrefutable to say that water plays a vital role in our life. We use water for drinking, bathing, washing, and cooking. But have you ever thought the water which you are consuming is bacteria free, and not contaminated? We cannot get pure water from taps or municipalities. There are several purifying processes to identify and purify water. However, the treatments methods are immensely expensive.
Many water tanks have a line in and line out, which are in and outs of the water tank. Although water in these tanks is refined on a daily basis, the upper part of water has never been used, leading to stagnation despite treating it with chlorine. Due to this phenomenon, the top layer becomes a place for more organic stuff such as bacteria, and algae. The only solution to this problem is by stimulating water or making it move. Therefore, researchers, Mohammad Alizadeh Fard, a doctoral student, and Brian Barkdoll, professor of civil and environmental engineering at Michigan Technological University came up with a solution.
To remedy the problem, Alizadeh Fard and Barkdoll created shower head-like attachments that can be added to new or existing water tanks for minimal cost. Adding a PVC-pipe sprinkler at the top of the tank, and a reverse sprinkler at the bottom of the tank injects water into the system and keeps all the water circulating.

Thus introducing a PVC-pipe sprinkler at the top and a reverse sprinkler at bottom alleviated the problem with relatively low cost.
Nevertheless, the problem is not only organic stuff, but micro-pollutants are also a concern, which is existed in water in very low concentrations. This cause long-term diseases to the people who are drinking the water. Since most of our treatment plans are not designed to purify this matter, a plausible solution is required. To resolve this problem, these researchers introduced an absorbent that absorbs a significant percentage of micropollutants. And this work is being done to check if it needs future application.
The polymer-coated magnetic nanoparticles were most effective at adsorbing Ketoprofen and BPA, removing the pollutants in 15 minutes with 98 and 95 percent effectiveness, respectively, with only 0.1 milligrams of the adsorbent.

These researchers came up with extraordinary ideas to treat water in a very effective and lucrative way. Because of water’s importance, we should encourage the idea and hope it gets disseminated.
