( 1 ) With developed Surface pore and specific surface area, ceramsite filter material is suitable for all kinds of microbial growth, also the stable and highly active biological membrane in its surface can handle water with high quality.
( 2 ) Take the advantage of regular shape, density moderate, easy to back flush, low energy consumption, back flush do not lose material, ceramsite filter material can overcome the disadvantage of big flow resistance and easy to cause oxidation pond jams andstrong back flush strength and scour broken easily of irregular granular filter material.
( 3 ) With void distribution uniform of precoat, ceramsite filter material can overcome the shortcomings of serious loss and frequent plugging or harden of water caused by non-uniform distribution of pore of filter material layer.( 4 ) With good use of size grading, ceramsite filter material has strong assimilative capacity and high filter material utilization ratio and wateread loss increase slowly and also with long operation cycle and big water yield.
( 5 ) Ceramsite filter material has compressive strength resistance to friction, high stability of physical and chemical and long service life, etc. Made of inorganic inert material under high temperature, it will not release any material to water to produce secondary pollution even soak for a long time.
