The Science of Aclear
Aclear 200 & 350 were created specifically to naturally, quickly, safely, and cost-effectively remove ammonia N or organic floc and decaying carbon matter from water bodies while converting organic phosphates and polyphosphates to orthophosphates, as well as a pre-treatment for patent pending Nclear media.
Aclear 350 is an all-natural biological microorganism treatment that has been successfully used in Florida lake bottoms to remove the organic floc created by decaying algae and plants. Excess algae are the result of excessive nutrients or eutrophication. Naturally occurring aerobic and anaerobic strains of microorganisms found in certain lake bottoms were isolated, cultivated, further refined, concentrated, and then mixed to create a highly selective strain of super microorganisms that aggressively, cost effectively, and safely digest organic lake floc. These microorganisms are dispersed in concentrations calibrated for each water body, and, as long as there is a sufficient food supply (organic floc) to support metabolism, the microorganisms will rapidly multiply and digest that food supply. During times of high food supply, Aclear multiplies at a high rate, effectively doubling in population every 15 to 20 minutes. As the food supply begins to diminish, the Aclear microorganisms naturally and quickly die without reproducing. Lab tests have indicated that organic volatile solids have been reduced by approximately 40-45% in just one week in sediment core samples we retrieved from Lake Apopka, (a large Florida lake with very high levels of excess nutrients). These results indicate that the readily decomposable or labile organic fraction of the sediments is rapidly metabolized by Aclear microorganisms. While it is difficult to distinguish decomposition studies from the laboratory to in situ environments, we believe that Aclear treatments in lakes with similarly flocculent and organic-rich sediments should achieve similarly high levels of reduction in overall sediment matter organic content, and that this process could occur and stabilize within two months. Significantly reducing these unnatural levels of decaying algae and plants is an essential step to removing excess nutrients and returning a water body to its safe, natural, healthy condition.
Our unique mixture of anaerobic and aerobic microorganisms digests organic phosphates and polyphosphates that would eventually be released back into the water column as orthophosphates. Vendors of competing bacteria or microorganism organic floc removal technologies will usually neglect to advise their customers that the phosphates removed using their bacteria treatments eventually will re-enter the water column when the bacteria residue decomposes. The revolutionary Aclear/Nclear two-stage excess nutrient removal treatment method is the only treatment that both efficiently removes the organic floc and sequesters the phosphorus originally bound as organic P when it is mineralized and released back into the water column. If the newly mineralized P is not quickly sequestered, it can further stimulate algal growth.
Aclear 200 is an all natural biological treatment that was specifically designed to remove ammonia from commercial process water utilizing a proprietary three stage high concentration Phosphates (P) and Ammonia (N) nutrient removal system. Aclear 200 has been successfully tested to remove concentrations as high as 330 ppm of ammonia (N) from toxic phosphate process water at a closed Florida phosphate mining and processing facility.
The three stage process starts with an application of Nclear to the process water to reduce high levels of phosphates to a comparatively low residual level and to raise the pH levels to condition the water for the microorganisms. During the second stage, Aclear 200, along with glycerin as a food source, is applied to oxidize high concentrations of ammonia (N). The residual phosphorus is used to help support microbial metabolism and growth. The ammonia (N) is oxidized by the Aclear 200 microorganisms in conjunction with oxygen from the aeration and ultimately converted to nitrate. The residual phosphorus used by the microorganisms ends up as a tiny amount of sludge in the Stage 2 treatment vessel.
In the third stage of treatment, the nitrates produced during stage two undergo conversion to nitrogen gas through a microbially-mediated process known as denitrification. The process water from stage two, including the microbial floc (which comprises a combination of the Aclear microorganisms interacting with the glycerin) is pumped to a third vessel that serves as a settling/reaction chamber. The floc, which is denser than water, sinks to the bottom of the settling chamber. The Aclear microorganisms then begin to denitrify the nitrate, using the glycerin as the carbon source, and the nitrate as the terminal electron acceptor. As denitrification proceeds, the nitrate is converted to nitrogen gas, which is largely insoluble in water, and will bubble out into the settling chamber head space. By the time the water in stage three is discharged, the level of the ammonia will be less than 1 ppm as N.
This is an environmentally safe, fast, low cost, and eco-friendly way of effectively remediating sites contaminated with high concentrations of phosphorus (P) and ammonia (N). Compared to other commercially available methods, our three stage approach is far superior, in part because other methods typically require very large amounts of ammonia gas to be released into the air around the treatment area. The Aclear microorganisms use the carbon source to create CO2 and water. The small amount of floc or sludge can be removed from the third treatment vessel and applied on site or sent to a land fill.
