What are the reasons for DT / ST Reverse Osmosis Modules?

High-quality membrane
Delivers consistent performance with high flux and rejection rates.

Innovative design
State-of-the-art design, including the next generation deflector for improved robustness and increased turbulence.

Improved efficiency
Radially symmetrical flow improves filtration efficiency and uniformity, ideal for high-purity processes.

Extended service life of the membranes
Reduces operating costs through extended service life and lower maintenance costs.

High packing density
The DT design maximizes the membrane area and improves performance.

Excellent anti-fouling properties
The optimized flow pattern minimizes dead zones and ensures efficient operation.

Versatility in pressure levels
Enables a range of pressure levels, up to 160 bar, to meet specific requirements.

High specific output
Up to twice the output of normal SWRO seawater elements.

Experience the difference with DT Foodgrade modules in the food sector

The previous membrane technology with spiral-wound modules is severely limited, especially when concentrating foodstuffs such as milk or coffee, due to the limitations in the permissible operating pressure and the solids tolerance.
Our investigations have shown that a higher concentration by a factor of >2 can be achieved with food grade DT module technology. This ensures that downstream technologies such as evaporators or spray dryers are relieved by 50%. This relief can be used either to increase throughput or simply to save around 50% energy and CO₂.

The possibilities of the new DT-Foodgrade modules are manifold:

Almost all available membranes can be integrated into the Food Grade DT module.
The radial, symmetrical flow routing enables a module without dead zones.
Operating pressures of up to 70 bar are possible.
The operating temperature can reach up to 45°C.
Both the connecting parts and the housing are made of 316L stainless steel.
The stability against acids and bases enables easy integration into CIP processes.

These DT (Disk-Tube Reverse Osmosis) membrane components according to FDA standards have excellent anti-fouling performance and are specially designed for concentration and treatment in food and beverage processing.
