Product Introduction: 
    Hexagonal honeycomb fillers are made from four materials: polypropylene (PP), polyvinyl chloride (PVC), ethylene-propylene copolymer, and fiberglass reinforced plastic (FRP). They are available in two assembly forms: inclined tubes and straight tubes. 
Applications: 
    Inclined tubes are mainly used for sedimentation and sand removal. Over the past decade, they have become the most widely used water treatment device in water supply and drainage projects. They offer advantages such as wide applicability, high treatment efficiency, and small footprint. They are 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 tanks, delivering excellent economic benefits. 
    Straight tubes are primarily used as microbial carriers in high-rate 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 municipal sewage.

Features of Inclined Tubes: 

1. Large wetted perimeter, small hydraulic radius.　
2. Excellent laminar flow conditions, with particle sedimentation undisturbed by turbulent flow.　
3. When the inclined tube length is 1 meter, the effective load is designed at 3-5 tons/m2·h. Optimal effluent quality is achieved when V0 is controlled within the range of 2.5-3.0 mm/s.　
4. When honeycomb inclined tubes with lengths of 2.0-3.0 meters are used at water intakes, 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.
Features of Straight Tubes: 
1. Higher treatment efficiency than activated sludge processes, with hydraulic loads typically at 100-200 m3/m2·day and organic loads at 2000-5000 g/m3, thus reducing the required footprint.
2. Lower aeration intensity than activated sludge processes, and no need for sludge recirculation, reducing power consumption and simplifying management.
3. Reduced sludge production, decreasing the workload for subsequent sludge dewatering and other treatments.
4. The generated sludge has good settleability, aiding in the removal of suspended solids in subsequent stages.
5. Strong adaptability, capable of handling a wide range of water qualities, with high tolerance for sudden changes in water quality and quantity, maintaining stable treatment performance.
