Controlled Floc Formation

Gentle Agitation

Flocculation tanks provide the gentle, sustained mixing needed for destabilised particles to collide and aggregate into larger flocs. Variable speed paddle mixers maintain optimal velocity gradients that promote floc growth without causing breakup, ensuring effective solids removal in downstream separation processes.

Flocculation is the second stage in chemical conditioning and treatment, following rapid mix. The gentle mixing energy allows microflocs formed during coagulation to collide and combine into larger, settleable flocs. Our flocculation tanks feature multiple compartments with tapered energy input, providing decreasing mixing intensity as flocs grow larger and more fragile.

Important Notes:

  • All dimensions are internal (usable) dimensions
  • Volumes calculated using rectangular prism formula: L × W × H
  • Actual working capacity typically 90-95% of total volume
  • Containerised tanks engineered for ISO container compatibility (width ≤ 2,400mm)
  • Free-standing tanks can be customised beyond standard dimensions
  • Wall thickness varies based on material, pressure, and chemical compatibility
