Company Overview

Climate Change Impacts

In recent years, heavy rains and typhoons caused by climate change have resulted in damage to water supply facilities and water outages. It is important to stockpile or secure water for emergencies, assuming that it will take time for relief supplies to arrive after a disaster strikes.

Adaptation Initiatives

We developed Cycloclean Portable SP, a water purification device that can be stored in a small suitcase and generates drinking water from indoor/outdoor sources during electricity/water outages after a disaster, and Cycloclean Portable SPX, which adds an electric pump to the above (Fig. 1). This device represents our technology that succeeded in downsizing the water purification treatment function. By passing through a three-stage filtration filter, it removes sand, mud, garbage, turbidity, mold odor, pesticides, organic solvents, general bacteria, E. coli, legionella, and cryptosporidium, and produces the same level of drinking water as tap water (Figs. 2 and 3).

We also offer other types of water purification systems, and the overview of each product is shown in the table below.

Effects / Expected Benefits

By utilizing these water purification systems, drinking/domestic water can be secured even during electricity/water outages due to disasters or drought. They are also already being used as a means of securing sanitary domestic and drinking water in water-poor regions of developing countries.
