Desludging ditches is a preferable work for nobody, but johkasous can save you from this unwanted work.
A Japanese river now
A Japanese river about 40 years ago without johkasou treatment
If you are tired of this, johkasous are there for you.
No more eutrophication as well
Without johkasous, our wastewater, which contain high volume of nitrogen and phosphorus directly flow into natural environment, resulting in eutrophication. In this state, the amount of these nutrients is excessively high in the water, and algae grow at an unusually rapid rate. Consequently, organisms other than algae die out due to the depletion of oxygen used up by algae.
