The solid/liquid filtration sector is faced with major challenges. More demanding process requirements and growing cost pressures are forcing the industry to act. Filter media are becoming the decisive success factor in this area because of stricter environmental legislation and constantly increasing expectations regarding filtration times. Better and better solutions are expected, particularly in the < 25 µm filter media range. Multifunctional fine steel filter meshes are now an indispensable element in many applications. To exploit the potentials to the full and meet the stricter regulations, an examination of the differences between the currently available mesh types is required. The precision of filtration, increased filtration capacities and increased durability are the relevant levers for application-specific optimisation. Optimized Dutch Weave from GKD – Gebr. Kufferath AG has proven itself in many situations. It increases the filter performance of the system, resulting in correspondingly improved productivity and significantly lower production costs. Optimized Dutch Weave (ODW) is used in numerous applications, e.g. fine filtration of treated waste water, high-viscosity motor oils and polymer filtration. The pore size as well as the retention and filtration characteristics of the mesh design is tailored precisely to the specific application. GKD's SOLID WEAVE business unit specialises in the customer-specific development and production of this mesh to create effective solutions for complex tasks.
