Client:

COPASA

Industry:

Wastewater

Location:

Ceara, Brazil

Key Issues:

Sludge
Scum
Odour

Project Summary:

Wastewater Treatment Plant

Challenge:

1. Extensive sludge in maturation lagoon (58% aggradation) 2. Formation of scum in reactors 3. Constant need to remove and discard sludge from reactors and filters 4. Odour

Results:

Effluent from maturation lagoons substantially clearer, devoid of solids and odour

Absence-of-deadzones

Absence of ‘dead zones’

island-of-scum

Island of scum significantly reduced

reduction-of-scum

Reduction in scum/sludge at outlets of maturation lagoons

scum-from-reactors

Scum from the reactors completely consumed

significant-reduction-odour

Significant reduction in odour

improvement-efficiency-plant

Improvement in efficiency of plant- reductions in BOD and COD

no-need-to-dispose-sludge-reactors

No need to dispose of sludge from reactors
