FlocShield
FlocShield is a next-generation biological technology designed to protect wastewater microorganisms from a wide range of toxins. Compounds like quats, chlorine, peracetic acid (PAA), hydrogen peroxide, caustics, solvents, and surfactants. These compounds routinely enter municipal and industrial wastewater streams, disrupting processes and destroying biomass. FlocShield it fortifies the floc itself, creating greater resilience toward toxins and environmental stressors.
Overcomes Toxicity and Shield Bacteria: FlocShield is designed to safeguard wastewater bacteria from toxic shocks, increasing resilience against common cleaning agents like Quats and PAAs.
Next Generation Wastewater Defense: Developed with cutting-edge technology to fortify the bacteria's natural polyprotein matrix, enhancing its defense mechanism against environmental toxins.
Robust Plan Operations: Great for systems that experience frequent cleanouts, FlocShield maintains bacterial health, preventing cloudy effluent and loss of nitrification.
Prevents Toxicity Upsets: FlocShield also offers protection against all toxic events.
Price range: $245.00 through $10,480.00

Product Details
Prevent Washouts and Protect Wastewater Biology from Toxic Shocks
FlocShield is an advanced biological solution formulated to defend industrial and municipal wastewater bacteria from toxic inflows—especially those caused by quaternary amines (Quats), peracetic acid (PAA), and other chemical inhibitors. As the use of aggressive industrial cleaners rises, many wastewater treatment plants are at higher risk for biological disruptions. FlocShield empowers operators to mitigate cell death, prevent washouts, maintain system balance, and restore biomass quickly after toxic events.
Using cutting-edge bioengineering, FlocShield strengthens the polyprotein matrix that bacteria naturally use to shield themselves from Quats and other toxins. This enhancement improves the microbial community’s resilience, enabling it to maintain BOD removal, flocculation, and settling performance even under chemical stress. The result: faster upset recovery, better ability to regrow mixed liquor, and improved performance in nutrient removal during both standard and high-toxicity conditions.
FlocShield is ideal for plant startup, influent toxicity protection, or as part of a long-term preventative treatment plan. It introduces a powerful blend of wastewater bugs, oxygen-rich biostimulants, and biocatalysts that help stabilize treatment processes and strengthen biological activity. FlocShield can be metered upstream, or added directly to the aeration basin or headworks of the plant.
Available in both 55-gallon drums and 275-gallon totes, FlocShield gives municipal and industrial wastewater operators a proactive strategy to protect against upstream toxins, rebuild microbial life, and reduce the risk of noncompliance.
