Using polyolefin and polyamide as raw materials, the strips are uniformly and densely distributed, which can ensure that the biofilm is fully mixed, penetrated and exchanged, so as to maintain good activity and spatial variability.
In practical applications, dense strips can collide multiple times and cut off bubbles. It will greatly improve the utilization rate of oxygen. Therefore, it is widely used in aerobic and anaerobic treatment processes. It is widely used in the packaging of biological contact oxidation tanks and hydrolysis acidification tanks.
