Natural Reservoir Restoration

Many reservoirs around the world have a need for improved water quality. Reservoir water quality issues vary, but concerns surrounding blue-green algae, manganese, iron, organic carbon, trihalomethanes, water taste and odor are at the top of the list. Trihalomethanes are cancer producers and manganese found in a water supply can have negative effects when used in laundering clothes.

Odor and bad taste in drinking water has plagued citizens around the world for years. Black coloration in reservoir water often stains residents’ clothing during laundering. Manganese, blue-green algae, and iron all contribute to these problems. Reservoir restoration processes that reduce or eliminate these factors can help improve reservoir water quality.

CLEAN-FLO International’s reservoir aeration systems effectively solvethe water quality issues and deliver a better solution for reservoir algae problems. CLEAN-FLO installs Continuous Laminar Flow Inversion and Oxygenation Systems in reservoirs to improve water quality. CLEAN-FLO’s unique water aeration systems continuously  circulate water to the surface from the reservoir bottom without creating turbulence (negative effects of aeration). Within weeks of the installation, there are dramatic improvements in water transparency, iron and manganese levels, as well as taste and odor problems.

Our inversion system gently turns reservoir water over and brings the foul-smelling gases up to the surface where they are neutralized by the atmosphere. In turn, inversion takes the oxygenated surface water down to the bottom where the oxygen kills the bacteria that produce the foul-smelling gases. The blue-green algae, which only grows on the surface, is taken to the bottom where it cannot grow due to lack of sunlight. Finally, by oxygenating the entire reservoir, iron and manganese that cause the discoloration of clothing and sinks, are oxidized and deposited on the reservoir bottom. Both oxidized manganese and oxidized iron then become useful in binding the phosphorus and nitrogen to the bottom sediment, making it no longer available for algal growth.

Based on the specific concerns at hand, CLEAN-FLO reservoir aeration systems and reservoir restoration systems can be supplemented with natural buffered phosphate precipitants,  beneficial bacteria (which feed on dead tree leaves and wastes that wash into reservoirs), and enzymes. The precipitants and the bacteria both remove food for aquatic plants and algae reducing their chances of survival.

Our experience in reservoir restoration since 1970 has shown that utilizing the CLEAN-FLO aeration process on reservoirs results in a significantly reduced cost of water treatment.
