Liquid surface cover ball has two different processing method. One is injection process. Other is foaming process. Owing to Injected cover ball’s weight is very light, it is very easy to wash way by strong water flow. Therefore, our company’s technical staffs have placed one solid steel ball inside the sphere. This change has not only increase the stability of the center of gravity, but also avoid of be blown way by strong wind. The overlapped edge will short Floating cover’s void fraction so as to reduce heat loss and evaporation rate.Finally. The combination of aerators and mixers with Floating cover leads to improved biological treatment performance and consistent high-quality effluent.
As for Foamed Liquid surface cover ball, due to the processing is foaming technology, it is very easy to soften under long time exposure.
