Hexagonal Honeycomb Filler(Inclined Tube Settler)
Materials:Polypropylene(PP),Polyvinyl Chloride(PVC),and Ethylene-Propylene Copolymer(EPC).
Assembly Configurations:Inclined tubes(for sedimentation)and straight tubes(for biological processes).
Primarily used forsedimentation and sand removal,inclined tube settlers have become the most widely adopted water treatment technology in water supply and drainage engineering over the past decade.Their advantages include:
-Broad applicability
-High treatment efficiency
-Compact footprint
Inclined Tube Settler
Typical Applications:
-Sand removal at water intakes
-Sedimentation in industrial and domestic water supply systems
-Wastewater sedimentation,oil separation,and tailings concentration
-Effective for bothnew constructionandretrofitting existing tanks,delivering significant economic benefits.
Straight Tubes
Mainly employed inbiological treatment systems:
-High-load biological filters
-Tower biofilters
-Submerged biofilters(contact oxidation tanks)
-Microbial carriers for biological rotating discs
-Biochemical treatment of industrial organic wastewater and municipal sewage
Inclined Tube Characteristics
1.Hydraulic Performance
-Large wetted perimeter,small hydraulic radius.
-Stable laminar flow regime,minimizing turbulent interference with particle settling.
2.Design Parameters
-Optimal effluent quality is achieved with a1-meter tube length,designed for an effective load of3–5 tons/m²·hand a flow velocity(v₀)
controlled within2.5–3.0 mm/s.
3.High Turbidity Adaptation
-With tube lengths of2.0–3.0 meters,inclined tubes can operate safely in high-turbidity environments containing50–100 kg/m³of silt.
4.Efficiency Comparison
-Treatment capacity is3–5×higherthan horizontal flow sedimentation tanks and2–3×higherthan accelerated/pulse clarifiers.
Technical Advantages
-Material Durability:Resistant to deformation,cracking,and aging,with a service life extended to5–10 years(versus 3–5 years for traditional PP fillers).
-Modular Design:Compatible with diverse water treatment scenarios through flexible configurations of inclined/straight tubes.
