Tertiary Wastewater Treatment
Tertiary wastewater treatment for councils and industrial operators, delivering effluent polishing and compliant discharge outcomes across Australia and New Zealand.
Meet Compliance and Discharge Quality Requirements with Tertiary Wastewater Treatment
As wastewater treatment plants operate under tightening discharge limits and increasing environmental scrutiny, councils and manufacturers must control effluent quality at the point of release. Residual suspended solids and algae from upstream processes can compromise tertiary wastewater disinfection performance if not controlled. Tertiary wastewater treatment provides the final level of control, stabilises effluent quality and ensures discharge standards are consistently met under variable operating conditions.
How FILTEC Reduces Risk in Tertiary Wastewater Treatment
FILTEC approaches tertiary water treatment as a compliance control system, not just a collection of individual processes. Our focus is on how wastewater polishing, filtration, and disinfection perform together to reliably meet discharge consent conditions.
Final-Barrier Compliance Focus
Tertiary treatment is designed as the last safeguard before discharge, with careful consideration of pathogen reduction, turbidity control, and disinfection performance.
Upstream Process Awareness
We account for variability introduced by secondary treatment and pond-based systems, including seasonal algae loading and solids carryover.
Fit-for-Purpose Technology Selection
Tertiary treatment technologies are selected based on effluent characteristics, regulatory drivers, and operational constraints, not standardised configurations.
Proven Systems in Council Applications
FILTEC delivers established wastewater disinfection systems and effluent polishing systems with demonstrated performance in Australian and New Zealand council environments.
Whole-of-Life Support
From early design and specification through commissioning and optimisation, FILTEC remains engaged to support long-term compliance outcomes.
Tertiary Wastewater Treatment Solutions
UV Disinfection Wastewater Systems
FILTEC supplies UV wastewater treatment solutions for tertiary wastewater treatment, including Trojan UV Signa and Trojan 3000+ systems. UV disinfection wastewater systems provide pathogen reduction without chemical residuals, and is often paired with tertiary wastewater filtration to manage turbidity and maintain stable UV performance.
Wastewater Chlorination Systems
Where chemical disinfection is required, FILTEC supports wastewater chlorination as part of tertiary wastewater disinfection systems. Chlorination may be applied as a primary or supplementary method to meet regulatory standards, redundancy needs, and operating conditions, with dosing strategies aligned to effluent targets.
Sand and Tertiary Filtration Systems
Sand filtration wastewater systems are widely used for wastewater and effluent polishing, removing residual suspended solids prior to disinfection. FILTEC delivers tertiary wastewater filtration solutions to improve effluent clarity, protect UV performance, and stabilise discharge quality. Systems are selected to suit effluent quality and site constraints.
Membrane Filtration Wastewater Systems
Membrane filtration wastewater systems provide advanced solids and pathogen removal where higher discharge quality is required. FILTEC offers membrane filtration as part of advanced wastewater treatment applications, where discharge limits are tightening or future reclaimed water objectives apply.
DAF Systems for Algae and Solids Removal
FILTEC delivers DAF algae removal solutions for councils operating facultative pond systems. DAF plants remove algae and fine solids prior to UV disinfection, improving UV transmittance and reducing compliance risk. DAF systems are applied as a tertiary polishing step following ponds to stabilise effluent quality before disinfection.
