How unmanned moving water treatment units will remove pollutants from rivers and lakes

Over two thirds of Earth’s surface is covered by water; less than a third is taken up by land. As Earth’s population continues to grow, people are putting ever-increasing pressure on the planet’s water resources. In a sense, our oceans, rivers, and other inland waters are being “squeezed” by human activities—not so they take up less room, but so their quality is reduced. Poorer water quality means water pollution.

Water Pollution Run Off

Pollution is one of the signs that humans have exceeded those limits. The full effects of water pollution across rivers are yet to emerge; however, it has already taken a severe toll on public health and caused significant economic damage.There are two ways in preventing river pollution .

1. Creating awareness campaign and legalizing stringent environment protection laws

2. Technology

And that’s were we are specialized. Some algal blooms and weed growth are the result of excess of nutrients (particularly phosphorus and nitrogen) in water and higher concentrations of these nutrients in water cause increased growth of algae and green plants. As more algae and plants grow, others die.


Our primary concern was to develop a technology that can momentously remove these dissolved nutrients out of water, This idea gave birth to THE BIO WATER TRAIN PROJECT. The BIO-WATER TRAIN is a novel technology to clean heavily polluted water bodies back to its stable state with maximum removal of dissolved pollutants, lead, cadmium, mercury, nitrate, phosphate, cyanobacteria, e-coli and other pathogens within the least period of time.


They are made up of specially build floating pontoon pods equipped with a submerged filtering and disinfecting UV sterilization unit. The entire system is driven by an Unmanned Surface Vessel. The filters are designed on the basis of water pollutant survey conducted by FENBOT. The estimated capacity of BWT is around 32 MLD (Million litres per day) thus providing a scientific and cost efficient method of removing pollutants from rivers, lakes and reservoirs at large scale. The train moves at a speed of 1.5m/sec. Thus increasing the contact between the filters and pollutants. Number of filtering and disinfection pods employed in the process depends upon the concentration of pollutants and the area of contamination.
