Editor's Notes
- The following is a brief description about AquaFiber’s world class surface water cleaning system. AquaFiber’s technology can restore Florida’s impaired lakes and streams making Florida a model for others to follow. Our goal is to make Florida the first clean water state in the nation.
- The background photo for this slide was taken on Lake Jesup and shows the Lake’s name written in a thick layer of surface algae floating on the surface. Our cutting edge technology called AquaLutions can remove this algae and the nutrients creating them permanently, and do it better and cheaper at scale than anyone else. AquaFiber began by cleaning the waters of Lake Apopka. In 2007, it was awarded a 5-year contract by the SJRWMD to relocate to Lake Jesup and continue its Vision of cleaning water for a healthy world there.
- AquaFiber’s technology is proven by successful completion of contracts for the SF and SJR WMDs, and independent verification of the results. The image on this slide depicts the Lake Jesup facility during its operation. However, as mentioned before, AquaFiber began developing its process on the shore of Lake Apopka where for more than six years it learned to produce water at drinking water clarity while also naturally decomposing the muck along the shoreline. Following successful completion of that project, the SJRWMD awarded AquaFiber a 5-year contract to build a commercial-scale facility that could harvest more than a metric ton per year of phosphorus from Lake Jesup. AquaFiber invested its own capital on a pay-for-performance basis, and operated for five years to accomplish that goal. The SJRWMD verified that our technology worked as advertised, and was also environmentally safe. The FDEP independently attested to those positive results and issued its own letter to that effect. The results showed that…
- AquaLutions can remove phosphorus and much more. One of the most important benefits of AquaLutions is that the nutrients and other pollutants are removed permanently and accomplished using non-toxic methods, not sequestered or transformed on site for future release. This picture shows a microcosm of our process. We bring lake water into the facility and run it through our trade secret system to produce clean water. The byproduct is an algal biomass that is harvested and provided at no cost to a strategic partner who produces a beneficial soil amendment for agriculture. Nothing is wasted or sequestered, and the fertilizer that we are putting on our lawns and crops today is being recycled for tomorrow. Using a weekly average that includes all non-operational time over five years at Lake Jesup, AquaFiber proved that its AquaLutions process can remove at least 75% of the phosphorus and 45% of the nitrogen. If you look at the most optimal quarter when downtime was limited and the system run at maximum efficiency, removal rates exceeded 90% for phosphorus and 65% for nitrogen. In addition to the exceptional nutrient removal rates, the latest iteration of the AquaLutions technology can also remove the decades of muck from the lake bottom permanently while also cleaning the water column above. The clean water produced is close to drinking water clarity, and since our process harvests algae (including the harmful ones), the water is up to 97% less toxic and almost 100% oxygen saturated.

- AquaFiber’s operational performance is unmatched. Our AquaLutions technology can remove nutrients, algae and muck at rates nobody else can, and do it at industrial scale. AquaFiber’s costs are the least expensive available, and our land requirement is very small (less than 10 acres). As mentioned on the previous slide, one of AquaFiber’s most impressive features is that we permanently remove the nutrients and recycle them. We don’t use toxic chemicals. We don’t leave the nutrients on site or in the water. And we don’t send them to a landfill or otherwise sequester them for future release. Once the nutrients, algae and muck are removed, they are converted to a beneficial product and provided at no cost to our strategic partner Anuvia Plant Nutrients Corporation (located in Zellwood, FL) for use as a soil amendment worldwide. The image shown on the right depicts how AquaFiber would expand its current facility from a 6 MGD plant to a 24 MGD plant. This plan would not only increase total capacity, but also bring Anuvia onsite so it could process the biomass and avoid having to transport it wet. All of this could be done on less than 10 acres. Besides additional nutrient removal, the expansion would create up to 40 “clean tech” jobs and further advance Seminole County’s position as a nationwide technology cluster.
- AquaLutions is the perfect solution for many of Florida’s other impaired water solutions. The image on the left is from ORCA and shows where nutrients are building up in the IRL; in those small canals and backwaters that feed the IRL where decades of septic tank and direct stormwater runoff have caused large accumulations of nutrients and muck. AquaFiber has tested its process successfully on the waters of the Indian River Lagoon where AquaLutions could be deployed to treat the hotspots. The picture on the right depicts a major component of the state’s Everglades restoration plan. Several STA’s will be built to remove nutrients. Those STAs will be fed with water from the FEBs. The water from these FEBs will be dirty and should be cleaned as much as possible so the STAs can function as they are designed, a final polishing before the water enters the Everglades. Without pre-treating the water, the STAs will reach their carrying capacity and require excavation more often than desired. AquaLutions has proven it could reduce the load and do much of the heavy lifting, so the STAs won’t become overloaded.
- AquaFiber provides a direct public benefit to the State of Florida. We have eleven years of measurable, rigorously examined water quality data that demonstrates our effectiveness as a world leader in water remediation technology. Our process has been proven and verified by multiple independent public and private sources including the FDEP, SFWMD and SJRWMD. This image here shows the quality of water produced by AquaLutions. This process has significant advantages. It can work at scales that have a meaningful restorative effect on large systems such as the St. Johns River, IRL, or Everglades. At 24 MGD, it can service all of the Lake Jesup BMAP removal requirements with one facility. It permanently removes the nutrients from the watershed. It produces fully oxygenated water close to drinking water clarity while harvesting an algal biomass that can be used for fertilizer; nothing is wasted and nutrients are recycled. AquaFiber doesn’t sequester nutrients onsite or use toxic chemicals, and after rigorous testing its technology has been deemed environmentally safe. By continuing and expanding AquaFiber’s facility on Lake Jesup, at least 40 new STEM jobs would be created, Seminole County would add to its expanding technology sector and Florida would become a clean water model for others to follow.
