♦FEATURES:
  The contact filter consisted of the bonding hard wavy plastic plates. The neat crisscross nodes assisted the air and waste water distributing and mixing between neighboring nodes in the filter bed, then contributed to constant contact and decomposition of the organic matter and microbes to result a good biological treatment.

  The structural design of this filter was concave-convex surface, providing a huge amount of surface area. The fine and rough degree of specially treated surface was suitable for microbial attachment, growth and flaking, also the structure of maximize space and low resistance was available for the circulation of air, water and suspemded solids. Considering the hydraulic laod of bio-film within the filter bed, each filter thickness of this structure was 0.4mm more to combine into a monomer. The compressive strength that tested by the Metal Industries Research&Development Centre was more than 1500kgf/m²,so there is no danger of collapse base. It is really an epoch-makinh product in low cost, high efficiency, and wiht economic benefits.
