Carbonized materials can conserve/purify water and air quality. An “old and new” measure that connects the generations.
Why do water quality and air environments improve with carbon materials?
The adsorption and decomposition characteristics of coniferous and hardwood carbonized materials depend on differences in each material quality (hole diameter), carbonization temperature (PH, etc.), and components (including trace elements such as calcium and magnesium, in addition to carbon).
Thus, materials should be selected in consideration of various conditions such as the water environment quality, and adsorption characteristics based on carbon material durability.

Characteristics of “Hard” Charcoal for Water Purification
A white-charcoal baked product molded from conifers and hardwoods, and carbonized at high temperature. With a fixed carbon ratio of 90% or more and a heavy specific gravity, it easy sinks into water and adsorbs soluble substances in the water, and the microbial film on the surface of the charcoal decomposes organic matter in water to purify the water of rivers, lakes and ponds, etc.
