Meeting the Australian Drinking Water Guidelines begins with effective particle removal. Coagulants for safe drinking water play a foundational role in reducing turbidity, organic matter and microbial risk before filtration and disinfection.
For utilities reassessing chemical inputs and sludge management strategies, Tanafloc has emerged as a plant-based alternative within this critical treatment step. Derived from natural tannins, Tanafloc is positioned as a biodegradable option that supports both treatment performance and sustainability goals.

Why coagulation remains central to water safety
Coagulation works by neutralising the electrical charges that keep fine particles suspended in water. Once destabilised, these particles form larger flocs that can settle and be removed through sedimentation and filtration.
The efficiency of this process directly affects downstream barriers. Poor coagulation increases filter loading, shortens run times and can elevate disinfectant demand. Effective coagulation, by contrast, improves clarity and reduces operational strain.
Tanafloc is used within this context as part of a strategy to optimise floc formation while limiting residual metal concentrations associated with some conventional aluminium-based coagulants.
Where Tanafloc fits in Australian treatment plants
Across Australia, utilities operate under diverse source water conditions. Variations in turbidity, organic carbon and pH require adaptable dosing strategies.
Tanafloc has been adopted in selected applications as a plant-based coagulant that performs across a broad pH range. Operators have reported improvements in sludge characteristics and reduced reliance on synthetic coagulants when Tanafloc is integrated into treatment processes.
In rural and regional systems, where chemical logistics and sludge handling can present challenges, Tanafloc offers a natural alternative that aligns with broader environmental objectives.
Balancing performance, compliance and sustainability
Selecting coagulants for safe drinking water is not solely about chemical substitution. It involves jar testing, dose optimisation and continuous turbidity monitoring to ensure compliance with regulatory standards.
Tanafloc must be evaluated under local conditions, just as any coagulant would be. Factors such as raw water variability, plant configuration and sludge disposal capacity influence performance outcomes.
Regular monitoring ensures that coagulation supports the multi-barrier framework required under national guidelines. When properly optimised, Tanafloc contributes to turbidity reduction, improved filter performance and enhanced public health protection.
As utilities pursue lower carbon footprints and reduced chemical dependency, plant-based solutions such as Tanafloc are increasingly part of strategic treatment discussions. Coagulants for safe drinking water remain essential, but the composition and sourcing of those coagulants are evolving.
Tanafloc Australia will be participating in Connected by Water 2026, joining industry leaders to discuss coagulants for safe drinking water and sustainable treatment innovation.
