Dairy Industry Coagulant
Cleaner, Safer Water for Dairy and Food Processing Industries
The dairy industry produces some of the most challenging wastewater streams in the food sector. High levels of chemical oxygen demand (COD), biochemical oxygen demand (BOD), fats, oils, and grease (FOG), and suspended solids make treatment complex and costly. Left untreated, these contaminants can cause oxygen depletion in water bodies, harming aquatic life and affecting human health.
At Tanafloc Australia, we provide a natural solution to this challenge. Our plant-based dairy industry coagulant, Tanfloc, is derived from the bark of the black wattle (Acacia) tree. Designed for dairy wastewater treatment, it offers high removal efficiency for solids and organic matter while supporting a cleaner, more sustainable water cycle
Sustainable Coagulation for Dairy Wastewater
Tanfloc is an innovative natural coagulant that replaces conventional inorganic coagulants such as ferric chloride, alum, and ferrous sulphate. By using plant-originated coagulants, dairy processors can significantly reduce their carbon footprint and improve overall wastewater quality.
Tanfloc works effectively as both a primary treatment coagulant and a supporting flocculation agent, seamlessly integrating with existing systems such as DAF units, clarifiers, or reverse osmosis pre-treatment setups. It enhances the separation of solids and organic matter, reducing total nitrogen, total dissolved solids, and chemical oxygen demand (COD) levels in the treated effluent.
This ensures better compliance with strict environmental standards while cutting back on chemical dependency and sludge management costs.
How It Works
The coagulation process in dairy wastewater treatment involves neutralising charged particles that cause turbidity and high biological oxygen demand. Tanfloc promotes coagulation–flocculation, allowing fine particles, fats, and casein micelles to bind together and settle more efficiently.
Tanfloc has demonstrated excellent COD removal efficiency and significant reduction in biochemical oxygen demand, outperforming several aluminium sulphate and ferrous sulfate alternatives under the same method and optimal conditions.
Key factors that contribute to its performance include:
- Optimum pH range for effective aggregation and floc formation
- Controlled coagulant dosage, determined through sampling and laboratory jar testing
By utilising coagulant plants such as black acacia, we deliver a cleaner and more stable process with minimal chemical residues, protecting both aquatic plants and ecosystems downstream.
Environmental and Operational Benefits
Tanfloc is designed not just for efficiency, but also for environmental integrity. Its biodegradable and non-toxic formulation makes it one of the safest and most sustainable choices for the treatment of dairy wastewater.
Environmental Advantages:
- Biodegradable and carbon-negative: For every tonne of CO₂ emitted during production, over 21 tonnes are absorbed by the acacia forests from which it originates.
- Reduced sludge production: Generates up to 30% less sludge than conventional metal salts, lowering disposal costs and storage requirements.
- Circular waste solutions: The resulting organic sludge can be composted, biodigested for biogas, or applied to agricultural land as fertiliser, closing the loop in waste management.
- Safer treated effluent: Minimises residual metal concentrations, protecting water bodies and aquatic life from long-term damage.
Operational Benefits:
- Compatible with biological treatment, reverse osmosis, and physicochemical treatment systems
- Improves dewatering performance and sludge handling
- Reduces dependency on powdered activated carbon, cleaning agents, and other chemical additives
- Supports high biological oxygen demand and strong wastewater streams typical in milk production and cheese making
Tanfloc makes it possible for dairy industries to meet environmental compliance standards while improving operational reliability and lowering overall treatment costs.
