Eutrophic, nutrient enriched water can induce adverse effects like harmful algal blooms (HABs) in aquatic ecosystems. Numerous studies have been conducted to control nutrients like phosphorus and nitrogen in order to mitigate the growth rate of HABs. During the spring semester of 2023, a research project investigated if the bentonite clay product, Phoslock, was able to remove phosphorus when it was added to distilled water and surface water under laboratory conditions. The researchers noted potential deficiencies in Phoslock’s ability to decrease the concentration of phosphorus while maintaining the initial value of adsorbed phosphorus. Expanding from this past research, two additional four-week studies will be conducted this fall with the same water sources, Phoslock, and a water treatment residual (WTR). The water treatment residual was collected from a Northeast Ohio water treatment facility and contains potassium aluminum sulphate (alum) and powder activated carbon (PAC). The study will investigate the ability of 1.6 grams of WTR-Phoslock to remove various concentrations of phosphate. With the introduction of this new variable, researchers will note if the WTR improves Phoslock’s ability to adsorb phosphorus and reduce the concentration.
