Filtration device
专利汇可以提供Filtration device专利检索，专利查询，专利分析的服务。并且PURPOSE: To extremely reduce frequency of exchange of raising water, by laying a nitrating tank in the downstream of an aerobic treatment tank of a filtration device consisting of a precipitating separation tank, aerating tanks and the aerobic treatment tank and a neutralizing tank in the downstream of the nitrating tank.
CONSTITUTION: A water tank of culture of fishes and shellfishes is communicated with a water tank such as water tank of living fish, raising water in the water tank is successively passed through a precipitating separation tank 2, aerating tanks 3 and 8 and an aerobic treatment tank 4 to form a filtration device having a closed circulation system. A nitrating tank 5 having nitrating bacteria is laid in the downstream of the aerobic treatment tank 4 of the filtration device, a neutralizing tank 7 having calcium carbonate pieces 10 such as coral pieces is set in the downstream of the nitrating tank 5 and optionally a sterilizing tank 6 is installed between the nitrating tank 5 and the neutralizing tank 7.
