Abstract:
A disposable netting assembly for a system for trapping floatable debris comprising:a flexible, stretchable, bag-shaped, knitted mesh net having a mouth at one end surrounded by a rim; a frame having an upstream side and a downstream side and comprised of members at a first side thereof coupled to members at an opposing side thereof by members tapering therebetween to facilitate secure retaining of the net to the frame while facilitating removability of the netting assembly from the system; the net being secured around its mouth to the frame; and the net being formed of an inner layer which faces the upstream side of the frame and an outer layer which faces the downstream side of the frame, each layer being formed of a mesh having openings therein, the openings of the inner layer being substantially larger than the openings of the outer layer; whereby fluid carrying debris enters the upstream side of the frame and passes first through the inner layer of the net which removes the substantially larger pieces of debris therefrom, then passes through the outer layer of the net which removes smaller pieces of debris therefrom.
