ものである。Conventional technology In recent years, the production volume of shochu factories has increased rapidly, but on the other hand, each producer is struggling with processing distillation waste liquid, which produces twice as much alcohol as extracted alcohol. In the distillation of authentic shochu, BDD is 60,000ppm under normal pressure distillation.
Even in vacuum distillation, high-concentration waste liquid of
Highly concentrated waste liquid reaching ooppm is discharged,
Diluting and sedimentating these highly concentrated waste liquids in an activated sludge tank requires enormous equipment costs, so the waste liquids are either dumped directly into the ocean, buried in mountains or forests, or dried in a dryer after adding a flocculant to the waste liquid. It is processed and used as fertilizer.
