The present invention relates to a water tank filtration apparatus with a new structure, which has a simple structure and can effectively remove contaminants included in water in a water tank. According to the present invention, the water tank filtration apparatus allows contaminants included in water to swell in a shape of foam by using a filtration unit (30), and sorts out only the generated foam to remove the same. Accordingly, the water tank filtration apparatus has a greatly simple structure and an excellent effect and is easily maintained. The water tank filtration apparatus comprises: an inflow pipe (10) to receive contaminants and water a pump (20) connected to the inflow pipe (10) and the filtration unit (30) removing the contaminants included in the water discharged from the pump (20).COPYRIGHT KIPO 2016본 발명은 구조가 간단하면서 수조의 물에 포함된 오염물질을 효과적으로 제거할 수 있도록 된 새로운 구조의 수조 여과장치에 관한 것이다.본 발명에 따른 수조 여과장치는 여과유닛(30)을 이용하여 물에 포함된 오염물질이 거품형태로 부풀어오르도록 하고, 이와 같이 발생된 거품만을 선별하여 제거함으로, 구조가 매우 간단하고 효과가 뛰어나면서, 유지관리가 용이한 장점이 있다.
