摘要： According to one aspect of the present invention, a filter assembly for removing particulate matter from a fluid stream is disclosed. The filter assembly includes a filter medium having a number of longitudinally extending spaced pleats. Opposing faces of adjacent pleats form a valley therebetween and include a pair of peak portions and a valley portion. The filter assembly further includes a plastic support net being pleated for supporting the filter medium in a pleated shape. The plastic support net includes spaced strands extending in a first direction and spaced strands extending in a second direction that is generally transverse the first direction. The strands extending in the first direction continuously extend over the valley and peak portions of opposing faces of adjacent filter medium pleats and are aligned in a direction substantially perpendicular to the longitudinal direction of the filter medium pleats.

摘要： In at least certain embodiments of the present invention, the present invention provides a plastic netting for use in various erosion control netting assembles. In at least one embodiment, the assembly comprises a first extruded plastic net, a second extruded plastic net secured to the first net, and a fiber matrix disposed between the nets. In at least another embodiment, the assembly comprises a first extruded plastic net, and a fiber matrix secured to and/or under the netting. In at least another embodiment, the net serves as a mulch control netting when secured to the ground over a mulch material. In yet another embodiment, the net serves as a turf reinforcement. In at least one embodiment, the net comprises a plurality of openings sufficiently sized, to enable small animals to traverse or weave through the erosion control netting assembly without getting trapped in the openings.
