New developments to this company’s Optimized Dutch Weave (ODW) meshes allow for improved throughput rate, better retention rate and longer filter-media life in water or wastewater filtration facilities. The flow-optimized ODW meshes combine reliable
filtration rates in the microfiltration range with almost three-times higher throughput rates than other recently available products, says the manufacturer. Other performance factors include high permeability, low pressure-loss coefficient, low clogging tendency and simplified cleaning. The special weave of the ODW mesh creates a slot-shaped pore geometry on the mesh surface, where the openings are smaller than the pores inside the mesh. With this design, particles above the specified separation limit are retained on the mesh surface. — GKD-USA, Inc., Cambridge, Md.
