From basic screening to engineered precision—how pretreatment defines the reliability of wastewater plants.
Pretreatment is not just the first step in a treatment line. Modern plants face fluctuating inflows, fibrous waste, sand, oil and high suspended solids. These conditions can demand more than a conventional bar screen.
The Centrefilte® Series presents modular pretreatment solutions covering precision screening, sand removal and sludge handling. Adaptability, reliability and maintenance access are central to the equipment selection.
Screening options
- Coarse screen (20–50 mm): Inward-flow type coarse screen.
- Arc-shaped intercept basket: Impact-resistant screen structure for complex inflow conditions.
- Internal screenings plate: Compact, high-strength structure for discharge.
- Inward-flow coarse screen (20–50 mm): Self-sealing wire rope type bar screen.
- Fine screen (5–10 mm): Variable-angle rotary perforated plate screen for fixed civil channel depths, to enhance unit flow capacity.
- Inward-flow plate-type fine screen (1–5 mm).
- Inward-flow super mesh screen: For large debris loads and high flows. The original article describes units designed for 200,000 m³/day or above; sizing is application-specific.
Grit, sludge and conveying equipment
- Integrated vortex-type grit separator
- Non-metallic chain-plate scraper, including double-layer arrangements
- Bridge-type sand suction machine
- Full-bridge and half-bridge sludge scraper
- Integrated sand washing and separation unit
- Floating screw conveyor
- Horizontal sand-discharge screw conveyor
When pretreatment improves, downstream operation can become more stable and efficient.
