Biological Treatment Systems

Biosolids Management
Our biosolids management solutions use BioDrying and pyrolysis to reduce sludge volume, stabilise organic material, and recover valuable biochar. These processes enhance sustainability by minimising waste disposal needs and supporting circular economy principles.
Membrane Bioreactors (MBRs)
Combining biological treatment with advanced membrane filtration, MBRs achieve superior effluent quality while significantly reducing footprint. These systems efficiently separate solids and pathogens, making them ideal for high-strength wastewater applications.Â


Moving Bed Biofilm Reactors (MBBRs)
MBBRs use suspended biofilm carriers for efficient biological treatment in compact tanks. FILTEC designs, supplies, and supports MBBR systems for municipal and industrial wastewater applications across New Zealand and Australia.
Aeration
FILTEC’s diffused aeration systems deliver fine bubbles for high oxygen transfer efficiency, supporting optimal secondary wastewater treatment. Our solutions help reduce energy use and improve performance across diverse wastewater applications.


Sequencing Batch Reactors (SBRs)
SBRs provide a flexible and cost-effective method for biological wastewater treatment by cycling through aeration and settling phases in a single tank. Their batch operation maximises efficiency in treating variable wastewater loads.
Trickling Filters
Utilising a fixed-film biological process, trickling filters enable effective organic matter degradation with minimal energy input. Their robust design ensures reliable secondary wastewater treatment with reduced operational complexity.
