《Outline》
概略
Our water purification system is using EcoBio Block(EBB), block that contains
Bacillus Natto together, with aerator(MFA). This biotreatment technology with
useful microorganism decomposes organic matter and purifies water quality. This
system is
i not only
l for
f water purification,
ifi i but
b also
l is
i the
h system that
h increases
i
diatom and relatively controls cyanobacteria(Blue-green algae) in lakes and
marshes. This technology is developed with cooperation with Kyushu University
Japan and Tongji University China.
China Tongji University is testing the real system of
MFA.
水質浄化用納豆菌群を封入されたブロックと必要に応じて曝気装置(弊社製MFA)を併用した浄化システム。有用微生物に
より有機物を積極的に分解し水質浄化を図る生物処理技術。同時に珪藻類の繁殖を促し、相対的に緑藻類・アオコなどの繁殖

If you change 2/3 of the water in the 60L tank every week the
result will be that 2 ton of water contain Ammonia and nitrate.
Immersing EBB in water Bacillus Natto will increase and purify water
