1. Equipment introduction

The sexangular honeycomb filler has two types: oblique tube and straight tube, three materials: PP, PVC and glass fiber. The oblique tube is mainly applied in precipitation and sand removing. It has the advantages of large wet circumference, small hydraulic radius, high treatment efficiency, less area occupied etc. And the straight tube is mainly used as microbial carrier in biological filtration tank, touch-oxidation tank and biological turning disc.
