Recommendations & Best Practices
- For most municipal water and wastewater applications, an **installation angle of 55-60°** provides a good balance between settling efficiency and sludge self-drainage.
- A **plate spacing of 50 mm** is standard for typical solids loading. Consider increasing spacing to 80-100 mm for applications with high solids content or sticky sludge to prevent clogging.
- Ensure the **Installation Baseline** provides adequate clearance for any sludge collection mechanisms (e.g., scrapers or hoppers) at the bottom of the basin. A minimum of 0.5m is common.
- The design should aim for a low **Surface Overflow Rate (SOR)**, typically 1-3 m³/m²/hr. A lower SOR allows for higher removal efficiency of fine particles. This tool calculates the area; divide your flow rate by this area to check your SOR.
