Lub Physics ntawm Particle tshem tawm hauv raj adderler system
Tube settlers water treatment relies on Hazen's sedimentation theory, where removal efficiency is inversely proportional to overflow rate. By installing inclined tube settler modules at 60° angles, the effective settling area increases by 20-25x compared to conventional clarifiers. As wastewater flows upward at 0.5-1.5 mm/s (tube settler system design velocity), particles with specific gravity >1.01 Slow downward raws phab ntsa phab ntsa. Cov yeeb yaj kiab no tam sim no ua:
- 95-99% TSS tshem tawm efficiency
- Cov nqi thauj khoom hydraulic mus txog 12 mp / m²² ha
- Flocculated particle capture mus rau 20 microns
Tseem ceeb rau raj khom nqi hauv dej kho cov nroj tsuag kev ua tau zoo yog tswj kom Laminar ntws (re<500) within tubes, preventing floc breakup.
