Water treatment apparatus and purification process using the water
摘要:
In a water treating apparatus the water is passed over a plurality of stages to a lower plane, each stage having a water trough, a section for the free fall of the water, and a catch. This makes possible the intensive mixing of the water with components of the air, especially oxygen and amino acids, as well as the action of natural light radiation onto the water.
