How we can purify the bubbled water with a lot of chemical materials?

We asked help to Professor Nakano at Nihon University in Japan.

It is of course important to have clean clothes for comfortable life but just take a look of the backside of the laundromat and follow the situation of waste water.

He is a professional on “artificial wetland” to purify the waste water.

He kindly came to Yap in 2017 and since then, he has been supporting our activities.

With his suggestion, we use a big tank for the filtering. In the 1,500 gallons tank, we set sand and coconut fiber inside for three layers. All the mechanism was set in December 2022.

Now the tank is working to purify the waste water.
