ROSTOR is its strength not only inhibits plant planktons from growing in the water, but also suppresses and reduce substantially Nitrogen(N) and Phosphorus(P), which are the nutrients of the plant planktons in the water.
ROSTOR is a step-forward improvement to constantly keep water clean by reducing the nutrients in the water and also by inhibition from generating the nutrients even in the sludge, which are possible by way of supplying OXYGEN from the surface to the deep depth of water.

There are two kinds of methods in the inhibition of algae from growing, one is to reduce the nutrients, the other to cut off the light, and ROSTOR was invented and developed considering both.

ROSTOR efficiently suppresses not only the growth but also the destructs the algae since it raises the waves on the surface of water by way of foaming and circulation of waters, which enable to suppress the growth of algae and cut off the light(more than 70%)in order not to infiltrate into the water.
