Formula 21HG
FOG Control Bacteria for Wastewater Systems

Breaks Down Fats, Oils, and Grease (FOG) to Improve Wastewater Treatment Performance

Why Choose Formula 21HG?

Advanced Grease Control for WWTPs and Food Processing

FOG accumulation in wastewater treatment plants and food processing facilities causes blockages, odors, and reduced operational efficiency. Grease buildup can lead to costly maintenance, system downtime, and environmental compliance challenges.

Formula 21HG is a specialized microbial product that breaks down fats, oils, grease, and organic deposits. Its bacteria blend creates a biomass that enhances BOD/COD removal, improves sludge settling, and supports system stability.

Ideal for municipal WWTPs, food processing facilities, lift stations, and collection systems needing proactive grease control.
