The basis of the high performance of ODWs is their special mesh construction. Their special weave creates a slot-shaped pore geometry on the mesh surface with smaller openings than the ones inside the mesh. In this way, particles above the specified separation limit are reliably retained on the mesh surface, while smaller particles can pass easily through the mesh interior. This prevents clogging and ensures the excellent dirt holding capacity of the ODW. At the same time, this mesh construction also ensures trouble-free cleaning. Because the separated particles build up on the surface of the filter rather than inside it, they can be easily detached through simple backwashing. Their lower resistance means that less filter surface is required, and pump power can also be set lower. The result: lower energy consumption and thus a smaller carbon footprint for the whole filtration plant.
Compared to other meshes available on the market, ODWs have substantially more stainless steel wires woven into their surfaces. This explains not only the great stability of the individual pores but also the unrivalled overall mechanical strength of ODW meshes, which is far beyond anything other filter media with comparable throughput rates can offer. As a result, ODW meshes are also significantly more reliable in long-term operation. GKD uses the established formula of the IMVT to determine the required pore size. The three-times-higher throughput rate of these even further optimised ODWs is made possible by their more porous mesh structure. In this way, their further improved filtration rates and their larger open surface contribute to even more efficient filtration processes.
