HIGH PERMEABILITY Flow-optimised ODW filter screen mesh for waste water filtration

5 10 15 20 micron Plain dutch weave (ODW) Betamesh filter media mesh screen

Dutch weave mesh: Twilled dutch weave and Plain dutch weave 

Plain Dutch weave wire cloth is woven using two sizes of wire. Smaller wires, as small as micron size, are used in the shute direction and are woven with a larger warp wire. The smaller wires are woven tightly together, providing a tight mesh for filtering. The larger wire provides strength to the mesh. The primary uses of this wire cloth are filtration and separation of liquid and slurry products.

Twill Dutch weave wire cloth combines Dutch and twill weaving to provide a fine mesh filtering cloth. Shute wires are passed over and under two warp wires, providing a tight, fine filter with tapered openings. The weaving process allows for the use of very fine wires, to micron size, producing filtering mesh for gas and liquid applications.

Optimized dutch weave

Optimized plain dutch weave is a further development of plain dutch weave for ultrafine filtration.

It is made up of a small number of thick warp wires and many thin weft wires. Due to the larger number of fine weft wires, these are interlocked during the production process. The result: slit-like openings with very small pore sizes (small edge length), which ensure a high level of permeability. Like plain dutch weave, optimized plain dutch weave offer a particularly high mechanical load-bearing capacity. One of the most frequent applications for this product is the filtration of fresh water and sewage.
