Water treatment: Bicycle-powered water purifying equipment


Cycloclean: Advancements in Bicycle-Powered Water Purifying Equipment

With two million children dying around the world due to unclean water, according to UNICEF, the need for purified water is more important than ever. A third of the world’s population still doesn’t have access to clean water.

Cycloclean by Nippon Basic Co., Ltd. aims to change all that. Part of the problem to this is that there are still some areas of the globe, in isolated rural areas and villages, with no power source. This makes it difficult to use any type of equipment that cleans water.

Cycloclean can produce five liters of clean drinking water per minute from raw water. Affixed to the rear seat of a custom-made bicycle, this unit is operated by simple pedal use, with no electricity or fuel required. It can turn water from the rivers, lakes, and swimming pools into drinkable water. Raw water can be dirty but not gassy or rotten. Cycloclean has been used in the past seven years throughout Japan in many cities, condos, retirement homes, labs, municipal offices and private companies.




Major Features and Advantages

I. Portability

Because it comes in the form of a bicycle, it can be moved from one spot to another extremely easily. Simply get on, pedal and ride to wherever clean water is needed. Tires are made from puncture-free solid rubber, allowing riders to access areas with rough or narrow terrain that may not be so easily accessible with other vehicles. Cycloclean features a basket and filtration system attached to the front and back. This is especially desirable in places that have been plagued by natural disaster.

II. Provides Large Amounts of Water

Cycloclean can produce up to three tons of clean water in just 10 hours, delivering water needed to 1,500 people per day from river and lake water. In one month’s time, it can produce between 90 and 100 tons of clean water. Its counterpart technology, called Desaliclean 2500, can convert sea water into drinking water. Its compact design allows it to be carried anywhere, filtering both sand and salt from ocean water.

III. Simple filter media

Each filter system is comprised of a microfiltration membrane, hybrid carbon filter and primary filter.
