Bio-Blocks
Fats, oils, and grease (FOG) from homes, restaurants, and other commercial or industrial facilities enter wastewater collection systems and accumulate in sewer lines and lift stations. This buildup of grease in lift stations causes clogging, reduces pump efficiency, increases maintenance requirements, and generates foul odors.
Bio-Blocks are designed to break down FOG and other organic waste that collects in lift stations. These solid blocks contain high-quality, high-count beneficial bacteria that naturally degrade organic materials. Regular use of Bio-Blocks supports proper system functioning, reduces the need for manual cleaning, and improves the overall efficiency of the sewage system.
By simply suspending the environmentally friendly Bio-Blocks in the treatment area, you can maintain lift station efficiency, reduce grease buildup, and save both time and money.
Bio-Blocks are a crucial component of our highly effective proactive grease control program.
