Mitigating Algal Blooms

Algal blooms can proliferate in both freshwater and marine environments when excessive amounts of nutrients, particularly nitrogen (N) and phosphorus (P), are introduced into the water. Increased urbanization may cause eutrophication, or the enrichment of N and P within aquatic ecosystems, which is a global issue and along with climate change may often lead to increased harmful algal bloom events within aquatic ecosystems. These blooms not only disrupt recreational activities but also present significant public health risks, as certain algal species produce toxins detrimental to both terrestrial and aquatic life as well as livestock and pets. Brooks et al (2016) reported that freshwater hatful algal blooms may very well be our biggest public health threat in the US.

South Carolina is especially prone to these blooms due to its numerous freshwater lakes, which are often regulated by dam management systems that influence water delivery affecting nutrient and sediment dynamics. Algal biomass is notably rich in limiting nutrients, such as P, which can exceed 10 mg/g in algal biomass, making it a viable candidate for use as an agricultural fertilizer. Nevertheless, the potential for toxin release by certain algal species remains a serious concern for homeowners and visitors alike.

To address the persistent problems caused by nuisance algal blooms, South Carolina Algae LLC offers a specialized solution through its patented Eco-Harvester technology . This advanced system can effectively navigate shallow coves and shorelines to remove suspended algal biomass without disturbing the underlying sediments. The collected algae is then converted into a concentrated, toxin-free fertilizer through our Eco-solids process  suitable for agricultural applications. It is important to consider that, depending on the severity of the algal infestation, removal may need to be performed on an annual basis.  In addition to fertilizers, we are also evaluating the potential to create biofuels and other innovative products from HABs.
