ABSTRACT:
The present invention intends to provide a water purification apparatus that is small and easy-to-use, yet being capable of efficiently creating flocs of impurities and removing the impurities from the wastewater in a single pass. To achieve this objective, an inner tubular anode12made of stainless steel or carbon is inserted into an outer tubular cathode11made of aluminum, leaving a predetermined intermediate space13between them, and electrolysis is carried out to produce aluminum hydroxide. The aluminum hydroxide thus produced serves as the medium for flocculating the impurities in the wastewater ascending the intermediate space13. The wastewater containing the flocs of impurities is filtrated with a filter18within a filtering and settling tank17. As a result, the impurities are completely removed from the wastewater.
