<p>A surface reactor 1a suitable for the treatment of a contaminated water body comprises a hollow structural cover 3 mounted on a buoyant flotation support 4 and an aerator 5. The aerator is housed within the hollow structural cover. Preferably, the cover comprises a growth medium 6 possessing one or more layers. The cover acts to contain contaminant carrying aerosols typically associated with mechanical aerators and also allows filtered air to pass through planted media 9, replacing and replenishing oxygen diffused by the aerator and providing a filter to malodorous gasses released in the aeration process. The aerator may be a surface or sub-surface aerator. The one or more layers of the growth medium can be a supporting layer, a moisture conveying or wicking substrate, an organic lignin based fibrous matting or a fibre reinforced soil. Typically, the reactor further comprises an anchoring system 12, a power supply provided by either a renewable energy source (7, Fig. 2) or a power line connected to a mains supply, a bio-augmentation device (13, Fig. 5), an ammonia probe (14, Fig. 5) adapted for communication with the bio-augmentation device and a sub-surface growth medium 10.</p> |
