Bioremediation

Understanding the solution

What is bioremediation?

Bioremediation uses living organisms or biological processes to reduce or transform pollutants. In complex waterbodies, it may need to be combined with source control, aeration, circulation, desludging, constructed wetlands or civil interventions.

Bioremediation is not a universal standalone remedy. Continuous untreated inflow, hydraulic constraints, toxic contamination, excessive sludge or inadequate maintenance may require additional civil, mechanical or source-control measures.

Suitable inputs or applications

Lakes and ponds
Drains receiving sewage
Decentralised wastewater systems
Institutional waterbodies
Selected industrial wastewater streams
Organic-load and odour problems
Algal and nutrient-management cases

Benefits

Actual outcomes depend on input quality, process configuration, operation, product quality and local conditions.

01

Pollution reduction

Support reduction of organic load and selected pollutants where conditions are suitable.

02

Odour management

Address anaerobic conditions and organic decomposition through integrated treatment.

03

Ecological restoration

Support improved water quality, habitat and system resilience.

04

Lower chemical dependence

Reduce reliance on repeated chemical dosing where a biological approach is appropriate.

05

Waterbody recovery

Create a structured plan for lakes, ponds, drains and decentralised systems.

06

Monitoring-led action

Use baseline and periodic water-quality data to adapt the intervention.

Project readiness

What We Need

A project cannot be responsibly configured without the following information.

Waterbody area, depth and volume
Pollution source and inflow
Flow pattern and retention time
Baseline laboratory data
Sewage or industrial discharge
Sludge and sediment condition

Dissolved oxygen and odour
Algal growth and nutrients
Existing aeration or treatment
Ownership and site access
Expected restoration objective
Long-term maintenance capacity

Our Scope

The final scope is defined after preliminary assessment and may involve specialist implementation partners.
