Organic Sediment and Muck Reduction in Lake Harmony

Case Study Showing Organic Sediment and Muck Reduction Over 4 Months – Lake Harmony, PA The following case study shows dramatic muck reduction and organic sediment removal from Lake Harmony in Pennsylvania after only 4 months of the CLEAN-FLO system. The Muck Reduction Challenge Lake Harmony is a small lake located in the Pocono Mountains […]

Inversion Oxygenation and Bioaugmentation Quickly Reduces Organic Sediments

The Challenge Lake Apopka is a 30,888 acre hyper-eutrophic lake located in central Florida. Once known for fantastic fishing, the lake had 28 fishing camps located around it. Decades of fertilizer and chemical use in adjoining parcels have contributed excessive nutrient inputs that have devastated the aquatic ecosystem and have transitioned the lake from a […]

CLEAN-FLO Inversion Oxygenation Reverses Eutrophication – Improves Raw Drinking Water

The Challenge Toa Vaca dam was built in 1972 to create an 836-acre raw drinking water reservoir in Puerto Rico. The maximum depth is about 174 feet. The intake tower for the water treatment plant has 6 intake gates, which are each about 30 feet apart. When built, it had a life expectancy of 300 […]

Inversion Oxygenation Helps Reduce Organic Sediments and Milfoil

The Challenge Over the years, organic sediments built up in the lower end of Lake St. Catherine (181 acre Little Lake), Wells, VT.  Milfoil growth started to dominate the lake and made navigation and water sport enjoyment almost impossible.  Chemical applications to kill the milfoil contributed to further accumulations of over 20 feet of organic […]

To whom it may concern:

We are pleased to provide this letter of recommendation for Clean-Flo and their lake aeration systems. We are a non-profit environmental association dedicated to restoring Lake Saint Catherine in western Vermont. We started working with Clean-Flo over five years ago when our research indicated that aeration might provide a solution for the shallower portions of our lake. Our working relationship has been quite productive, and our initial results show we are meeting our objectives.
The shallower portions of Lake Saint Catherine actually have many feet of organic material that has not decomposed due to an anaerobic condition. In places, we have four to five feet of water over a soft bottom with over 30 feet of this organic material to the hard bottom of this kettle pond lake. It took us several years to get a permit from the State of Vermont. Clean-Flo helped us prepare the design and the permit application, delivered the aeration system to our site and then provided technical advice for installation. The permit was approved in 2012 and initiated in August 2012. After one and one-half seasons we have had promising results.

The depth of the lake to the soft bottom has increased at each of the nine diffuser locations. The increases in depth at diffusers ranges from 6 inches to 24 inches. At the mid-points of the diffuser field, we have recorded an increased depth of roughly 6 inches. We have several control points north and south of the aeration field. No change in depth has been measured at these control points outside the aeration zone. We are pleased with these results and have recently received a permit to increase the number of diffusers from 9 to 13.
We are pleased to recommend Clean-Flo to organizations facing similar environmental challenges.

Clean-Flo’s staffs have been terrific to work with. They have been very good in helping to figure out not only what products we need but also keeping us within our budget. They have made sure that we have detailed instruction on how and when to apply their biological products. Even though they are several states away, we have been able to reach them by phone if we have questions easily or by e-mail to send them pictures or videos so that they can help us figure out what to do next. We have been very happy with their customer service and especially with our results.

A few years ago it was observed that the pond was filling up with organic debris from the surrounding trees and taking on a murky appearance. Early in 2015, we had some fish die, and we knew we needed to do something quickly to remediate this situation. We first considered dredging the pond but the expense was high and the time to acquire permits would further jeopardize the pond appearance. It was at the time we were referred to Clean-Flo as a possible solution for our pond. Clean-Flo analyzed our pond water, designed the solution and had all the equipment in place in about a month. We are now approaching a year that the system has been installed and the pond looks great!

A Clean-Flo inversion oxygenation system was installed in late April go 2006, a significant drop in bacteria levels was observed after a week of operation. The systems turned off a few weeks after installation and bacteria levels rose. When the system was restarted, a decrease in bacteria levels was again recorded, suggesting that the Clean-Flo system was directly affecting bacteria levels in the lake.

We installed the Clean-Flo aeration system in March 2007 and noticed an immediate reduction of algae during the 2007 season. The algae coverage dropped from over 90% of the surface to about 60%. However, the real impact has come in there, our second season of usage. After an initial large algae bloom in late spring, the algae has disappeared. We now have less than 10% coverage, and this is limited to the shallowest, stagnant area of the pond.
