Biological Contact Filter (BCF)

Water & Soil Water Quality Improvement / Water Management Technology Water Supply / Sewerage

Efficiently remove offensive smell and taste such as mold odor substances, ammonium nitrogen, manganese that causes manganese contained water, and surfactants, by populating microorganisms with the purification ability on the surface of activated carbon as a carrier, and contacting them with raw water.

Fluidized-Bed Gasification and Melting Furnace

Fluidized-Bed Gasification and Melting Furnace

Waste Treatment & Recycling Waste Treatment / Management Gasification and Melting Technology

Our fluidized-bed gasification and melting furnace employs a high-temperature combustion and melting process in which waste is gasified in the fluidized sand layer and the gas then reacts with air, eventually producing slag from melted ash. The facility is capable of performing this process without a fossil fuel supply, using only waste as an energy source.

Fluidized-Bed Gasification and Combustion

Waste Treatment & Recycling Waste Treatment / Management Gasification and Melting Technology

Our fluidized-bed gasification furnace employs fluid sand to gasify and a relatively low volume of air to efficiently incinerate waste, which enables the downsizing of plants.
