A floating aquatic plant water treatment system (31) utilizes a serpentine channel (36) defined by dividing walls (34). Floating plants (72) are distributed across the water surface by a floating grid structure (32). The grid structure (32) is preassembled into Z-fold bundles (88) which are towed on

A floating aquatic plant water treatment system (31) utilizes a serpentine channel (36) defined by dividing walls (34). Floating plants (72) are distributed across the water surface by a floating grid structure (32). The grid structure (32) is preassembled into Z-fold bundles (88) which are towed onto the water and unfolded. The treatment system uses sprayers (62) to control growth conditions. Porous baffles (46) are placed along portions of the channel (36) to provide intimate contact with a larger portion of the water while allowing free flow.

A directional sprayer system for use with a floating aquatic plant water treatment system having a body of wastewater with a water surface with floating aquatic plants on the water surface which take up nutrients found in the wastewater, the sprayer system comprising: sprayers having spray patterns that are directed over, and substantially cover the water surface; sprayer mounting means coupled to the sprayers for mounting the sprayers relative to the water surface so the sprayers spray over the water surface; sprayer direction changing means, coupled to the sprayers, for changing direction of the sprayers; and fluid delivery means, coupled to the sprayers, for delivering fluid to the sprayers to be sprayed over the water surface, wherein the fluid delivery means includes a source of additional nutrients and injection means connected to the source of additional nutrients for injecting the additional nutrients into the fluid, the additional nutrients causing the floating aquatic plants to treat the wastewater in a desired manner, and the fluid being sprayed on the surface of the water so the floating aquatic plants can absorb a desired amount of the additional nutrients and so the body of water is not entirely contaminated with the additional nutrients in the fluid. A method of treating wastewater contained within a wastewater containment area, the method comprising: providing a floating grid structure in the wastewater containment area for defining water surface areas for growth of floating aquatic plants; growing floating aquatic plants within the water surface areas defined by the grid structure so that the plants take up nutrients found in the wastewater; spraying water over the water surface areas; and injecting additional nutrients into the water to be sprayed through injection means for growth of the floating aquatic plants, the additional nutrients controlling growth of the aquatic plants to cause the aquatic plants to treat the wastewater in a desired manner.
