Dairy Factory Water Reuse Solution

Small- to medium-sized dairy factories typically generate 30–150 kL/day of high-strength wastewater containing fats, proteins, emulsified dairy solids, lactose, detergents, and bacterial loads. Most sites use Dissolved Air Flotation (DAF) as the core primary treatment step. DAF is excellent at removing fats and solids, but it does not address dissolved organics, odour, surfactants, or microbial risks.

By installing our OHX Advanced Oxidation Process (AOP) followed by our integrated polishing system after the DAF, the factory can reclaim treated water for potential reuse such as:

-Internal cleaning & wash-down

-CIP pre-rinse or intermediate rinse

-Cooling tower make‑up 

-Irrigation and landscaping

-Construction and dust suppression water (onselling)

This transforms wastewater from an ongoing disposal cost into a valuable internal resource.

One module of this modular system treats a 50 kL/day side-stream, allowing dairy factories to reclaim ~18 million Litres of high-quality water per year—without disrupting existing DAF/lagoon infrastructure.
