Honeycomb tubes come in two kinds: straight tubes and inclined tubes, made of two kinds of material :PP,PVC.

Straight Tubes:

1. Mainly used as microbial carriers of microbial biofilters like high load biological filter, tower biological filter, Submerged Biological Aerated Filters and biological rotating disks.

2. Used in treating and purifying Industrial organic wastewaters and urban sewage.

Application Area:

Water plant, chemical fertilizer, paper, printing and dyeing, chemical industry, metallurgy, power generation, water and livelihood, such as precipitation and industrial sewage water purification in urban water supplying.
