The inclined tubes produced by our factory are also known as hexagonal honeycomb fillers. They are available in two assembly forms: inclined tubes and straight tubes, and are made from three materials: polypropylene, ethylene-propylene copolymer, and polyvinyl chloride. In particular, the ethylene-propylene copolymer has received widespread acclaim from users of all sizes across the country in recent years. Its main advantages include: high toughness, excellent assembly strength, resistance to deformation and brittleness, long service life, and an extended anti-aging period. Compared to the original polypropylene filler's lifespan of 3-5 years, it can now last 5-8 years. Based on recent trends, inclined tubes made from ethylene-propylene copolymer are becoming the preferred choice for various wood processing plants.:3-5 can be extended to5-8 years of service life. Based on recent development trends, wood processing plants everywhere are increasingly opting for ethylene-propylene copolymer inclined tube fillers.

    Inclined tubes are primarily used for sedimentation and sand removal. They are currently the most widely used and mature water treatment devices in water supply and drainage engineering. They offer advantages such as wide applicability, high treatment efficiency, and small footprint. They are suitable for sand removal at water inlets, sedimentation in general industrial and domestic water supply, sewage sedimentation, oil separation, tailings concentration, and other treatments. They are applicable for both new projects and the renovation of existing old pools, delivering excellent economic benefits. Main features::

    1, Large wetted perimeter, small hydraulic radius.

    2, Good laminar flow conditions, particle sedimentation is not disturbed by turbulent flow.

    3, When the inclined tube length is1meter, the effective load is designed at3-5/m22, withVOcontrolled within the range of2.5to3.0mm/s, ensuring optimal effluent quality.

    4, The treatment capacity of an inclined tube sedimentation tank is3-5times that of a horizontal flow sedimentation tank, and2-3times that of an accelerated clarifier and a pulse clarifier.

    Straight tubes are mainly used in biological filters and high-load biological filters, tower biological filters, submerged biological filters(also known as contact oxidation tanks), and as microbial carriers in biological rotating discs. They are used for the biochemical treatment of industrial organic wastewater and urban sewage. Main features::

    1, Treatment efficiency is higher than that of activated sludge processes. The typical hydraulic load is100-200m3/m22per day, and the organic load is2000-5000g/m33. This reduces the required footprint.

    2, Aeration intensity is lower than that of activated sludge processes, and no sludge recirculation is required, thus reducing power consumption and simplifying management.

    3, Minimal sludge production, reducing the workload of post-treatment processes such as sludge dewatering.

    4, The sludge produced has good settleability, which aids in the removal of suspended solids in subsequent stages.

    5, High adaptability, capable of handling a wide range of water qualities, with strong tolerance to shock loads from sudden changes in water quality and quantity, maintaining stable treatment performance.
