Advanced Biological
Wastewater Treatment

Applying 30 years of engineering expertise in environmental biotechnology. Increase capacity up to 30% without increasing footprint.

Engineering & Innovation

Based on our 30 years long experience in environmental biotechnology, we develop novel technologies and bioprocesses for advanced biological wastewater treatment.

Our approach is based on upgrading the existing WWTP by introducing pre-selected microbial cultures in suspended form—such as flocs, aerobic granules, or cultures immobilized on activated carbon or curtains.

As a result, a higher process efficiency, better energy balance, and fewer investment and operational costs are consistently achieved across capacities ranging from 500 to 5000 Population Equivalents (PE).

Our Promise

Whether deploying Solar-Priority, Fuel-Priority, or Grid-Connected installations, our solutions are engineered for operational autonomy, structural resilience, and long-term sustainability even in constrained environments.

Centratech Facility

Our Expertise & Services

Comprehensive diagnostic, testing, and deployment from 200L pilot plants up to industrial scale volume.

Treatment

Robust technologies for both industrial and municipal wastewater treatment.

Diagnostic

Precise detection of target pollutants using advanced bacterial biosensors.

Recovery

Efficient recovery of organic compounds directly from biomass.

Reuse

Safe reuse and reclamation of active ingredients in industrial applications.

Tailor-made Biomass

Tailor-made Biomass

To improve biological processes, CENTRATECH provides tailor-made microbial biomass pre-selected to target complex compounds. This provides a rapid increase in process activity and activated sludge adaptation.

Lab and Pilot Testing

Laboratory & Pilot Testing

From initial Treatability and Detailed adaptation lab tests to 200L/industrial scale pilot plants, we evaluate treatment under field conditions before scaling up to ensure absolute commercial solidness.

Proprietary Solutions

SBR Technology

Containerized SBR Technology

Compact modular plants designed to treat industrial and municipal wastewater. Highly robust and customisable to meet functional requirements and regulatory standards.

Stages include: screening, extended aeration, sedimentation, and sludge recirculation.

ARGUS Systems

ARGUS Systems

Aerobic Granular Biomass Upgrade System. A high-performance solution that combines biological degradation and solid-liquid separation in a single reactor.

Granular biomass is cultivated in a side-stream column bioreactor and injected directly into the main biological system, reducing footprint radically.
