UNISOL’s DTRO membrane – the latest development for the food industry


Just in time for AnugaFoodTec, UNISOL is presenting its latest development for the food industry: the UNISOL Food Grade DTRO module. This module makes it possible to use the proven DT module technology in many new applications.

The previous membrane technology with spiral-wound modules is severely restricted, especially when concentrating foodstuffs such as milk or coffee, due to the limitations in the permissible operating pressure and the solids tolerance.

Our tests have shown that UNISOL Food Grade DT module technology can achieve a higher concentration by a factor of >2. 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 UNISOL DTRO modules are manifold:

  • Almost all available membranes can be integrated into the Food Grade DT module.
  • The radial, symmetrical flow guidance 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 of the UNISOL Food Grade DT module are made of 316L stainless steel. The stability against acids and bases enables easy integration into CIP processes.

“UNISOL is proud to be at the forefront of technological development in the food industry with this innovation,” explains Walter Lamparter, one of the managing directors of WTA UNISOL GmbH. “Through continuous innovation and the pursuit of efficiency and sustainability, we want to help shape the future of food production. We look forward to WTA UNISOL participating in Anuga FoodTec 2024 this year, the world’s leading trade fair for the food and beverage industry.”

From March 19 to 22, 2024, WTA UNISOL can be found in Hall 4.1, Stand C006.
