The honeycomb inclined tube has become a commonly used settling tank filler in the water treatment industry. However, the quality of the honeycomb inclined tube filler determines its service life, as well as the smoothness of the welding and installation process. Now, the experts from Jinrong Honeycomb Inclined Tube will teach you how to identify the quality of the inclined tubes. There are two types of hexagonal honeycomb inclined tubes: inclined tubes and straight tubes, available in three materials: polypropylene (PP), polyvinyl chloride (PVC), and fiberglass.
Application Range of Honeycomb Inclined Tube Fillers:
Honeycomb inclined tubes are mainly used for various sedimentation and sand removal purposes. They have been widely adopted in water supply and drainage engineering over the past decade and have become a significant water treatment device. They offer a wide application range, high treatment efficiency, and a small footprint, making them suitable for sand removal at water inlets, general industrial and domestic water sedimentation, sewage sedimentation, oil separation, and tailing concentration treatment. They are applicable for both new projects and the renovation of existing old tanks, yielding good economic benefits.
Specifications and Prices of Hexagonal Honeycomb Inclined Tubes: The specifications for potable water sedimentation inclined tubes are φ35X0.45 and φ35X0.5, while for sewage, they are φ50X0.45, φ50X0.5, φ80X0.6, and φ80X0.8. The price of honeycomb inclined tubes for potable water is higher because they must meet drinking water standards and be made of non-toxic PP material, priced from over 400 to over 500 yuan per cubic meter. The price for sewage honeycomb inclined tubes ranges from over 300 to over 400 yuan. Dongying's honeycomb inclined tube prices are reasonable, with manufacturers producing hexagonal honeycomb inclined tube fillers. Honeycomb inclined tube fillers come in inclined and straight tube forms, with materials including PP and PVC. The inclined tubes are primarily used for sand removal at water inlets, industrial and domestic water sedimentation, sewage sedimentation, oil separation, and tailings concentration treatment, and can also be used for the renovation of old tanks. Key features include a large wet perimeter, small hydraulic radius, good laminar flow state, and particle sedimentation unaffected by flocculation interference. Straight tubes are used in tower-type biological filters, high-load biological filters, and submerged biological filters (also known as contact oxidation tanks), as well as microbial carriers for biological rotating discs. They are mainly used for the biochemical treatment of industrial organic wastewater and municipal sewage, with higher treatment efficiency than activated sludge tanks and a smaller footprint. The aeration intensity is lower than that of activated sludge tanks, and there is no need for sludge return; the sludge volume is small, and adaptability is strong, significantly reducing the workload after sludge dewatering.
Currently, filtration processes often face issues with the sand layer surface becoming hardened or the filter layer becoming blocked, leading to actual backwashing intensity and time far exceeding design parameters. This is also caused by the residual microorganisms, biodegradable organic substances, and dissolved oxygen in the effluent from oxidation tanks undergoing comprehensive biochemical reactions. Since most design processes employ post-filtration disinfection, the aforementioned biochemical reactions continue during sedimentation and filtration. To ensure the normal operation of the clarification process, it is recommended to use pre-filtration disinfection processes. After 15 years of operation, the Qingdao Beer wastewater biochemical treatment process has adopted pre-filtration disinfection to kill bacteria without experiencing filter device blockage issues. When filtration is employed, it is recommended to increase the carbon layer with trace aeration to form a biocarbon process, with an aeration intensity of about 5% of the water volume, which can extend the regeneration cycle. Dongying's honeycomb inclined tube prices are reasonable, with hexagonal honeycomb tubes made from imported modified ethylene-propylene copolymer plastic, formed into hexagonal tubes using infrared constant temperature mechanical stretching, and then welded into a complete product using patented technology and high-frequency welding for installation at customer sites.
Honeycomb inclined tubes are mainly used for sand removal at water inlets, industrial and domestic water sedimentation, sewage sedimentation, oil separation, and tailings concentration treatment, and can also be used for the renovation of old tanks. Key features include a large wet perimeter, small hydraulic radius, good laminar flow state, and particle sedimentation unaffected by flocculation interference. In addition to their use in water purification and sewage treatment plants, they are also effective in coal mine water treatment, coal washing plant water treatment, electric power concentration tanks, tailing water treatment, pharmaceutical and paper mill wastewater treatment, particularly benefiting the renovation of water treatment plants and wastewater treatment projects.
