Old Methods Bring New Ideas:
Blue green algae is nothing new to lake-going Minnesotans. But is it just a Minnesota issue? Many states across the country are facing the ever-growing green monster, we call blue green algae. Many states are finding it harder to control and stop the spreading from one water body to the next. Many times, the large blooms of algae will float away downstream to another river, lake or beach, possibly affecting and causing economic issues in surrounding areas.
In Florida, an engineering group is combining efforts with the Army Corp of Engineers to combat this algae problem. The engineering group has a history of working with wastewater and drinking water public facilities. The two parties are working on a special project to help combat blue green algae blooms on a large lake in Florida. The company is taking its knowledge of "bubbling up" or floating the algae blooms to the waters surface and then using a method of skimming to remove it. The "bubbling up" effect is technically known as “dissolved air flotation”.
The Army Corp of Engineers received funding from Congress last year for the project. They are ultimately looking for scalable solutions that can be applied anywhere across the country. The current system ,which is under development and being tested, can treat as much as 100 million gallons per day.
The engineers are even looking for possible long-term uses for the algae that is harvested. These possibilities could include bio-fuels or other consumer used products like shoes. This information was part of an interesting article I recently read. For more details, and the full reading of the article, click on the link to check it out.
