In general, livestock wastes, industrial wastes, domestic wastes, and sewage discharged from homes, factories, and livestock farms are contaminated with large amounts of nutrients (nitrogen, phosphorus) that cause eutrophication and red tide.

As these nutrients are found to be the main culprit causing red tide and water pollution, various wastewaters are always treated with purified water and discharged at the lowest possible BOD (Biological Oxygen Demand) status. Will not.

In other words, the wastewater contains a large amount of nitrogen and phosphorus, organic substances that pollute rivers and coasts, and contains a large amount of chromaticity. When discharged as it is without purification, the ecosystem is destroyed with red tide. Since serious destruction is often occurring, the water quality standards for effluent are gradually increasing.

Accordingly, in the roots, media (media, also known as tins), which are mediators for attaching and surviving microorganisms, are introduced into the aeration tank of the wastewater treatment device, and the microorganisms attached to the media installed in the aeration tank are transferred to the wastewater passing through the aeration tank. It is responsible for reducing BOD by decomposing organic matter.
