ABSTRACT:
For the treatment of waste water in the liquid treatment of a textile material, air bubbles are generated in water containing floating impurities stored tentatively in a waste water tank so as to adhere the impurities on the surface of the air bubbles, adhering the impurities together with air bubbles on the surface of a filter comprising a mesh belt or a mesh drum by pulling up the filter successively, and removing the impurities from the filter thus pulled up due to the effect of vacuum suction, and an apparatus therefor. The impurities remaining still on the surface of the filter may further be removed therefrom by washing the filter with the aid of water and air jets.
