The working principle of the microfiltration machine is that when the aquaculture water passes through the microporous screen on the
microfiltration drum, the solid waste in the aquaculture water body is separated under the rotating action of the rotating drum,
so that the water body is purified and recycled. At the same time as filtering, the rotation of the drum and the force of the
backwash water can be used to make the microporous screen clean in time, so that the device can always maintain a good working
condition.
