Ceramic Fine Bubble Diffuser is a high efficiency energy-saving air diffusion device with brown fused aluminum oxide being the main raw material. The process of compression molding and high temperature sintering which makes it of greater hardness and stable chemical properties. This kind of diffuser can be applied to all kinds of domestic sewage, industrial wastewater and aquaculture aeration systems for biochemical treatment.
