We focused on a practical treatment of animal liquid manure for land application using some
materials in an aerated reactor. After solid-liquid separation of animal manure in a barn, liquid
manure is moved to three to five tanks sequentially. At each tank a reactor is suspended and
aerated with air pump. The reactor consists of pumice, granite, and soil pellet, not only promoting
biological digestion of the manure but also providing some minerals in it. The soil pellet is
sometimes alternated by the powdery soil, spread at the bottom of the tanks. The aerated reactor
system is called "BMW", meaning bacteria, mineral, and wastewater. After qualified for three
week to a month in the sequential tanks, the wastewater, low in organic materials and rich in
minerals, is used for plant cultivation as an activated fertilizer.
