Secondary Wastewater Treatment
Secondary wastewater treatment systems for councils and industrial operators across Australia and New Zealand, to manage organic loading and treatment capacity.
Controlling Organic Load Through Biological Treatment
Secondary wastewater treatment is the primary biological stage responsible for removing dissolved organic matter, reducing BOD and COD, and supporting biological nutrient removal. For councils and industrial operators, effective secondary treatment is critical to meeting consent conditions, managing variable influent loads, and protecting receiving environments as population growth and production demands place increasing pressure on wastewater treatment systems.
How FILTEC Reduces Risk in Biological Treatment
FILTEC delivers secondary wastewater treatment through integrated, proven biological treatment expertise. We reduce operational and compliance risk by selecting secondary systems matched to influent characteristics, performance objectives, and downstream process requirements.
Biological Process Understanding
Secondary biological treatment is designed with a clear understanding of how processes remove dissolved organic matter, reduce BOD and COD, and support nutrient removal.
Application-Specific System Selection
Systems are selected based on influent variability, loading rates, footprint constraints, and treatment objectives, not standardised configurations.
Proven Biological Technologies
FILTEC delivers established secondary biological treatment technologies, including MBR, MBBR, and SBR systems, applied across municipal and industrial environments.
Integrated Treatment Design
Secondary treatment is designed to integrate effectively with upstream primary treatment and downstream tertiary processes, supporting stable whole-of-plant performance.
Lifecycle Support Capability
From early design and specification through commissioning and optimisation, FILTEC supports wastewater treatment systems throughout their operational lifecycle.
Secondary Wastewater Treatment Solutions
Biosolids Management
FILTEC delivers biosolids management solutions, including biodrying and pyrolysis, to stabilise secondary sludge, reduce volume, and improve handling. These systems support compliant biosolids reuse, energy recovery, or disposal while integrating with secondary wastewater treatment processes.
Membrane Bioreactors (MBRs)
FILTEC supplies membrane bioreactor wastewater treatment systems combining biological treatment with membrane filtration to produce high-quality effluent. MBR wastewater treatment suits space-constrained sites, delivering consistent secondary performance, low suspended solids, and supporting downstream tertiary treatment or future reuse.
Moving Bed Biofilm Reactors (MBBRs)
MBBR wastewater treatment systems use suspended biofilm carriers to provide efficient biological treatment within compact reactor volumes. FILTEC designs, supplies, and supports MBBR systems for municipal and industrial applications where footprint constraints, load variability, or staged capacity expansion are required.
Aeration
FILTEC delivers diffused aeration systems to support secondary biological treatment performance. Aeration systems are designed to match biological loading requirements, optimise oxygen transfer, and support stable treatment conditions while managing energy use across activated sludge, MBR, MBBR, and SBR processes.
Sequencing Batch Reactors (SBRs)
FILTEC supplies sequencing batch reactor wastewater treatment systems for flexible secondary biological treatment. SBRs combine aeration, settling, and decanting within a single reactor, offering operational flexibility for councils and industrial operators managing variable flows and organic loading conditions.
