All-Plastic (EPDM) Honeycomb Inclined Tube Purifier Our factory produces hexagonal honeycomb fillers in two forms: inclined tubes and straight tubes. The materials used include polypropylene and fiberglass reinforced plastic (FRP). Inclined tubes are primarily used for various sedimentation and sand removal purposes. Over the past decade, they have become one of the most widely adopted water treatment devices in water supply and drainage engineering. They offer a wide range of applications, high treatment efficiency, and a 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 can be used in both new construction projects and the renovation of existing old pools, delivering excellent economic benefits. Main Features: 1. Large wetted perimeter, small hydraulic radius. 2. Excellent laminar flow conditions, with minimal turbulent interference to particle sedimentation. 3. When the inclined tube length is 1 meter, the effective load is designed at 3–5 tons/m2·h. The optimal effluent quality is achieved when the overflow rate (VO) is controlled within the range of 2.5–3.0 mm/s. 4. When FRP honeycomb inclined tubes with a length of 2–3.0 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 twice that of an accelerated clarifier or pulsator clarifier. > Technical Parameters Reference Table of Technical Parameters for Inclined Tube (Plate) Fillers | Item | Hexagonal Honeycomb Inclined Tube Filler | Inclined Plate Filler | |---------------------------|------------------------------------------|-----------------------| | Material | PP (Ethylene-Propylene Copolymer) | PVC (Polyvinyl Chloride) | FRP (Fiberglass Reinforced Plastic) | PP (Ethylene-Propylene Copolymer) | PVC (Polyvinyl Chloride) | FRP (Fiberglass Reinforced Plastic) | | Common Specifications (mm) | ?35, ?50, ?80 | ?35, ?50, ?80 | ?35, ?50, ?80 | 35, 50, 80 | 35, 50, 80 | 35, 50, 80 | | Standard Quantity /m2 | 42, 32, 20 | 42, 32, 20 | 42, 32, 20 | 27, 19, 12 | 27, 19, 12 | 27, 19, 12 | | Common Thickness (mm) | 0.35, 0.45, 0.65 | 0.35, 0.45, 0.65 | 0.3, 0.5, 0.7 | 1–2, 1–2, 1–2 | 1–2, 1–2, 1–2 | 1–2, 1–2, 1–2 | | Reference Weight (kg/m2) | 21, 16, 16 | 31, 23, 23 | 41, 31, 31 | 33–66, 23–46, 15–30 | 50–100, 35–70, 23–46 | 65–130, 45–90, 30–60 | | Single Piece Dimensions (mm) | 1000×1000×δ | 1000×1000×δ | 1000×1000×δ | Customized by customer | Customized by customer | Customized by customer | | Formed Dimensions (mm) | 1000×1000×866 | 1000×1000×866 | 1000×1000×866 | Customized by customer | Customized by customer | Customized by customer | | Application | Water supply, reclaimed water, sewage | Sewage | Water supply, reclaimed water, sewage | Water supply, reclaimed water, sewage | Sewage | Water supply, reclaimed water, sewage | | Appearance Color | Milky white | Sky blue | Customizable | Milky white | Gray | Customizable | | Forming Method | Soldering with electric iron | Adhesive bonding | Adhesive bonding | Plastic welding | Plastic welding | Adhesive bonding | | Installation | On-site soldering | On-site bonding | On-site bonding | On-site welding | On-site welding | On-site bonding | | Installation Angle | 60° | 60° | 60° | 60° | 60° | 60° | | Cost | Low | Medium | High | Medium | Low | High | | Service Life | Long | Short | Relatively long | Long | Short | Relatively long | | Frequency of Use | Common | Rare | Infrequent | Infrequent | Infrequent | Infrequent | | Operating Temperature | 5–80°C | 5–50°C | 5–70°C | 5–80°C | 5–50°C | 5–70°C | | Density (g/cm3) | 0.92 | 1.35–1.46 | 1.8 | 0.92 | 1.35–1.46 | 1.8 | | Product Characteristics | Flexible, prone to floating | Prone to aging, brittle, slightly toxic | Acid and alkali resistant | Acid and alkali resistant, aesthetically pleasing | Slightly toxic | Acid and alkali resistant | | Production Method | Prefabricated in factory | Prefabricated in factory | Prefabricated in factory | On-site fabrication | On-site fabrication | Prefabricated in factory | | Standard Packaging | Bare, strapped with packaging tape | Bare, strapped with packaging tape | Bare, strapped with packaging tape | Bulk | Bulk | Bulk | | Transportation Form | Transported as loose pieces | Transported as loose pieces | Transported as loose pieces | Transported as loose plates | Transported as loose plates | Transported as loose plates | > Precautions 1. Since the density of the inclined tube filler is 0.92, slightly less than that of water, it must be secured with ?10mm threaded steel or round steel reinforcement bars placed above the filler to prevent loosening and floating. Both the steel bars and angle steel should be treated with epoxy coal tar asphalt for corrosion protection. 2. Plate A as shown in the diagram must be installed; otherwise, the inclined tube filler may tilt or even collapse! > Installation Procedure 1. Installation of Sludge Discharge Pipe at the Bottom of the Sedimentation Tank The installation of the inclined tube sedimentation tank generally starts from the bottom. First, complete the installation of the sludge discharge pipeline system at the very bottom. Ensure that the openings of the sludge discharge pipes meet the design requirements and are securely fixed. Only after verification should you proceed to the next installation step. 2. Completion of Filler Support Installation According to the installation drawings of the filler support for the inclined tube sedimentation tank, install the filler support in place first. Check that all welded joints are secure and that the support structure is strong enough to bear the weight of the filler. Complete the anti-corrosion treatment on the surface of the support. 3. Completion of Inclined Tube Filler Soldering Follow the soldering method for the inclined tube filler, treating each package of inclined tube filler as a separate soldering unit. After soldering, each unit covers an area of 1m2. Stack the soldered units neatly on-site (keep a small number of loose pieces as spares). 4. Assembly of Inclined Tube Filler in the Tank Assemble the soldered filler units from left to right on top of the filler support. Maintain a constant angle of 60°. Apply appropriate pressure during the sequential assembly of each unit. If the dimensions do not fit perfectly when assembling to the far right, use loose inclined tube filler pieces for soldering and assembly until everything is in place. 5. Securing the Top of the Inclined Tube Filler Since the density of the inclined tube filler is 0.92, slightly less than that of water, after assembling the filler in the tank, reinforce it by placing ?10mm round steel bars from left to right above the filler (each unit requires two round steel bars passing above). Secure both ends of the round steel bars firmly to the walls of the sedimentation tank. Installing the round steel bars effectively prevents the inclined tube filler from loosening and floating during initial use. The round steel bars should be treated with epoxy coal tar asphalt for corrosion protection. 6. Operation and Debugging of the Inclined Tube Sedimentation Tank - 1. Check that the incoming water is evenly distributed to avoid impact on the sedimentation tank, which could affect sedimentation efficiency. - 2. Adjust the height and levelness of the effluent weir trough to ensure even water outflow. - 3. After completing the above steps, the installation of the inclined tube sedimentation tank filler is fully complete. Once put into normal operation, determine the sludge discharge cycle based on the concentration of suspended solids in the incoming water. Ensure timely sludge discharge to maintain optimal operation of the inclined tube sedimentation tank and satisfactory effluent quality.
