Abstract
A submersible sieve apparatus provided with an exoskeletal frame enveloping a filter element and a detached post-filter backing; positioned to strain a lotic stream of entrained sediment prior to or upon being deposited. The frame can positioned and manipulated for greater efficiency. The filter and backing will take the shape of the frame and the backing may or may not be attached.
Claims7
A new submersible sieve apparatus configured to be submerged into a channel of liquid, to be used as a, full gradient spectrum, lotic strainer to entrap entrained sediment, the sieve comprising:
- an exoskeletal frame made from a pliable metal encased in a light weight polypropylene material that allows for the frame to take and maintain a shape for placement in the lotic channel under stress;
- a filter element of measurable non-zero partial impedance to liquid and having a plurality of passages therethrough, wherein the passages vary in size to provide an irregular surface, supported and enveloped by the frame;
- and
- a detached post-filter backing adjacent the filter element, having no passages therethrough, supported and enveloped by the frame and adjacent filter element.
