摘要

A three-dimensional grid for use as an algal turf growing surface contains a horizontal planar basal net containing a series of horizontal planar members and upwardly directed members.

主权项

1. A three-dimensional basal screen for growing algae comprising:
(a) horizontal planar members joined together at nodes to form adjoining open-spaced grids; and (b) upwardly directed members extending from at least some of the horizontal planar memberswherein at least one of the following conditions prevails:
(i) at least some of the horizontal planar members and/or upwardly directed members are independently selected from monofilaments and multi-filaments; (ii) the horizontal planar members, upwardly directed members or both horizontal planar members and upwardly directed members are composed of fiberglass or natural fibers; (iii) at least some of the horizontal planar members or upwardly directed members are straight filaments, twisted filaments, woven filaments or braided filaments; (iv) at least some of the upwardly directed members are helically wound filaments; or (v) the horizontal planar members and upwardly directed members are a uniform filament wherein the upwardly directed portion of the uniform filament is in a different plane than the horizontal planar members.
