>Product Introduction
Hexagonal honeycomb media (inclined tube media) 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.
>Application Scope
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 a wide range of applications, 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 applicable for both new projects and the renovation of existing old tanks, delivering good economic benefits.
Straight tubes are mainly used as microbial carriers in high-load biofilters, tower biofilters, submerged biofilters (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 undisturbed by turbulent flow.
·3. When the inclined tube length is 1 meter, the effective load is designed at 3-5 tons/m²·h. With V0 controlled within 2.5-3.0 mm/s, the effluent quality is optimal.
·4. When using honeycomb inclined tubes at water intakes with a 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 pulsator clarifier.
·Straight tube features:
·1. Higher treatment efficiency than activated sludge process, with hydraulic loads typically 100-200 m³/m²·day and organic loads 2000-5000 g/m³, thus reducing the required footprint.
·2. Lower aeration intensity than activated sludge process, and no sludge return is needed, reducing power consumption and simplifying management.
·3. Less sludge production, reducing the workload of post-treatment processes like sludge dewatering.
·4. The generated sludge has good settleability, aiding in the removal of suspended solids in subsequent stages.
·5. Strong adaptability, suitable for a wide range of water qualities, with high tolerance to shock loads from sudden changes in water quality and quantity, maintaining stable treatment results.
