Coagulation & Flocculation

Flocculation
Baffle Box

A folded-plate flocculation baffle box replaces mechanical agitation with geometry. Water passes through a channel formed by folded plates, and every fold alternately contracts and expands the flow, shedding micro-vortices that drive particle collisions and floc growth — with no impeller, no drive unit and no power input. The modules drop into an existing concrete basin or channel.

Why this flocculation baffle box

Mixing energy
from geometry alone

Flocculation needs vigorous mixing while the particles are still small and gentle mixing once the flocs have grown. A folded-plate channel delivers both along a single flow path, without a single moving part.

Micro-vortices at every fold

Each fold alternately contracts and expands the flow area. Water accelerates through the contraction and slows in the expansion, shedding a train of micro-vortices that repeatedly bring fine particles into contact — so collision frequency rises without adding mechanical energy.

Shear that falls as flocs grow

Velocity is stepped down along the plate train. The early stages run at the higher velocity that particle collisions need; the later stages run slower, so flocs that have already formed are not broken apart again before they reach the settling zone.

Modular retrofit, low upkeep

Folded-plate packs are lowered into an existing concrete basin or channel and fixed to the structure. There is no agitator shaft, bearing or gearbox to lubricate or replace, which keeps operating cost and maintenance work low over the service life.
