It is undeniable that industrial and population development, as well as climate change, reduce the availability of water, especially raw water.

Raw water, which in fact comes from surface water sources, becomes more easily contaminated with bacteria, viruses, and other chemicals that will harm the body.

This causes humans to no longer be free to drink water in nature. More and more people are carrying bottled water when traveling.

On the other hand, the packaging used is generally made of plastic and cannot be reused so that it will pollute the environment.

Seeing this phenomenon, three Water Engineering students, Faculty of Engineering, Universitas Brawijaya, made a water purification bottle called W-Health Bottle.

This bottle is equipped with an additional filter that can turn river water into ready-to-drink water. The filter is also easy to replace and its maintenance is not difficult.

The convenient design of the bottle is also suitable for carrying anywhere. A comfortable design, a cheaper price, and a quality that is not inferior to those on the market make it an option.

This W-Health Bottle was made by Sekar Salsabila as the team leader along with her two colleagues, Garda Satria Pinayungan and Endru Hakkun Nururrahman.

Sekar explained that the filter used was in the form of a tube with a diameter of 4.2 cm and a height of 3 cm. The materials used are silica sand, activated carbon, zeolite, and nylon fabric.

Silica sand is used to reduce suspended solids in water, activated carbon can reduce color and eliminate water toxicity, zeolites can reduce color turbidity in water, and nylon filters can filter large particles.

With the guidance of Ir. Sri Wahyuni, ST., MT., Ph.D, IPM., the team will fight to represent UB in the upcoming XXXIV National Student Scientific Week (PIMNAS).

“Hopefully this bottle can be a solution in providing clean water for travelers in particular and society in general,” hoped Sekar. (humasft)
