Abstract

PURPOSE: To ensure a simple and high-efficiency treating method when the culutre pond water is cleansed through the filtering and circulating, by performing the water sprinkling and filtering onto the cleansing agent containing the fixed foam filled into the filter frame.
CONSTITUTION: When the culture pond water is cleansed, a box, the bottom of which is made of the metal net or the hurdles or a metal net frame is installed at the upper part of the pond. And then the cut pieces of the capillary foam made of the synthetic resin such as the polystyrene or polyethylene foam are filled into the said box or frame in the form of layers to form the cleansing agent. Then the scooped pond water is scattered on the filter frame filled with such cleansing agents, and thus the pond water can be cleansed while dropping with contact with the capillary foam and due to the function of the bacteria attached to the foam.
