Regenerable phosphorus filter for industrial and municipal water treatment

DiaPure provides regenerable phosphorus removal solutions for industrial process water and municipal wastewater treatment.

Our technology is designed to help operators meet increasingly stringent discharge requirements, reduce waste and operating costs, and recover phosphorus for circular nutrient management.

From food production to phosphorus recovery
Food and beverage production generates process water containing valuable nutrients. DiaPure enables industries to capture and recover phosphorus from these water streams, helping turn a waste flow into a resource.

Industrial process water

Robust phosphorus removal for demanding applications

Industries generating phosphorus-containing process water often face significant variations in flow, phosphorus load and water composition. DiaPure is designed to provide stable phosphorus removal under changing operating conditions and can be integrated into existing treatment processes.

Typical applications include:

• Food and beverage processing
• Chemical and materials industries
• Energy, recycling and bioprocessing
• Other industries generating phosphorus-containing process or wastewater

DiaPure can be integrated into existing treatment systems or used as a dedicated polishing step to help achieve required discharge levels.

Benefits for industry:

• Effective phosphorus removal, including at high phosphorus concentrations
• Regenerable filter media – reducing the need for regular filter replacement
• Designed for low operating and maintenance requirements
• Easy integration into existing treatment systems
• Reduced material use and waste compared with single-use filter media
• Supports resource efficiency and sustainability targets

Municipal wastewater treatment

Targeted treatment of phosphorus-rich side streams

Municipal and private wastewater treatment plants face increasingly stringent requirements for phosphorus removal, driven by both national regulation and evolving EU requirements.

Many treatment plants also generate smaller, phosphorus-rich side streams, such as reject water from sludge dewatering and other internal return flows. Although these flows are relatively small, they can contribute significantly to the overall phosphorus load entering the main treatment process.

DiaPure is particularly suited to treating concentrated phosphorus-rich side streams, enabling efficient removal from relatively small flows and reducing the load on the main biological and chemical treatment processes.

Depending on the plant configuration and treatment objectives, DiaPure can also be used as a complementary treatment or polishing step within an existing process.

Suitable for:

• Phosphorus removal from concentrated side streams
• Reducing phosphorus loads on the main treatment process
• Improving process stability
• Recovering phosphorus for circular nutrient management
• Integration with existing treatment infrastructure with minimal disruption

Phosphorus recovery – from waste to resource

The phosphorus captured by DiaPure can be recovered through regeneration and returned to the nutrient cycle rather than being treated as waste.

This creates an opportunity to combine effective phosphorus removal with resource recovery and reduced material consumption.

Key benefits of DiaPure

• High phosphorus removal efficiency
• Regenerable filter media
• Reduced filter waste and material handling
• Robust and reliable operation
• Integration into existing treatment systems
• Potential for phosphorus recovery and circular nutrient use

DiaPure contributes to

• Cleaner water through effective phosphorus removal
• Resource efficiency through regenerable technology
• Reduced waste by reusing the filter media
• Phosphorus recovery and circular nutrient management
• Compliance with current and future environmental requirements
