Modular floating covers
In many industrial and residential areas, odors and noxious vapors emitted from open effluent ponds, lagoons and tanks can create a variety of environmental issues.
Permeable covers restrict air, water, and gas movement into and out of the liquid. Covers, such as the the Hexprotect covers, have been shown to be more suitable for reducing odor from livestock manure facilities than impermeable material. An aerobic layer is established on the top of the cover, so that some of the odorous compounds that escape may be aerobically broken down before they are released to the atmosphere.
Air-filled balls such as the Armor Ball have also been used as a floating cover for outdoor manure storage facilities. One study reported about 15% ammonia losses from cattle slurry (85% reduction), and between 5% and 12% from pig slurry (up to 95% reduction) as compared to 100% losses from uncovered control tanks.
Solid impermeable cover accumulates dirt and residues over time that promotes vegetation growth on top of the cover. Vegetation will not grow on our modular covers due to proprietary design and the continuous motion of the covers on the surface of the water.
The main challenge most operators faces is to find an economical solution, both with initial and operating costs, and to minimize maintenance. Covers that have regular or even moderate labor requirements, such as solid covers, are at a definite disadvantage when compared to our modular covers that require no maintenance at all.
Covering a lagoon has many added benefits besides eliminating odor emission.
All our covers offer substantial advantage over solid covers:
