Product Introduction
　　Hexagonal honeycomb packing (inclined tube packing) is available in three materials: polypropylene (PP), polyvinyl chloride (PVC), and ethylene-propylene copolymer. It comes in two assembly forms: inclined tube and straight tube.

Scope of Application
　　Inclined tubes are mainly used for various sedimentation and sand removal purposes. Over the past decade, they have become a widely adopted water treatment device in water supply and drainage engineering. They offer advantages such as broad applicability, high treatment efficiency, and small footprint. Suitable for sand removal at water intakes, sedimentation in general industrial and domestic water supply, sewage sedimentation, oil separation, and tailings concentration, they are effective for both new projects and the renovation of existing old pools, delivering excellent economic benefits.
　　Straight tubes are primarily used as microbial carriers in high-load biological filters, tower biological filters, submerged biological filters (also known as contact oxidation tanks), and biological rotating discs for the biochemical treatment of industrial organic wastewater and urban sewage.

Product Features
· Inclined tube features:
· 1. Large wetted perimeter, small hydraulic radius.
· 2. Excellent laminar flow conditions, with particle sedimentation unaffected by turbulent flow interference.
· 3. When the inclined tube length is 1 meter, the effective load is designed at 3-5 tons/m2·hour. With V0 controlled within 2.5-3.0 mm/second, the effluent quality is optimal.
· 4. When using honeycomb inclined tubes at water intakes with a tube length of 2.0–3.0 meters, they can safely operate and treat high turbidity water with sediment content of 50-100 kg/m3.
· 5. The treatment capacity of an inclined tube sedimentation tank is 3-5 times that of a horizontal flow sedimentation tank, and 2-3 times that of an accelerated clarifier or pulse clarifier.
· Straight tube features:
· 1. Higher treatment efficiency than the activated sludge process, with a general hydraulic load of 100-200 m3/m2·day and an organic load of 2000-5000 g/m3, thus reducing the required footprint.
· 2. Lower aeration intensity than the activated sludge process, and no need for sludge回流, reducing power consumption and simplifying management.
· 3. Reduced sludge volume, decreasing the workload for subsequent sludge dewatering and other treatments.
· 4. The generated sludge has good settleability, facilitating the removal of suspended solids in subsequent stages.
· 5. Strong adaptability, capable of handling a wide range of water qualities, with high tolerance to shock loads from sudden changes in water quality and quantity, maintaining stable treatment效果.
