Bio-Blocks: Effective Odor, Sludge, and FOG Reduction for Lift Stations

Fats, oils, and grease (FOG) from homes, restaurants, and various commercial and industrial facilities can accumulate in collection systems, leading to buildup in sewer lines and lift stations.

This buildup of grease in lift stations often results in clogging, reduced pump efficiency, increased maintenance needs, and unpleasant odors.

Bio-Blocks are designed to break down FOG and other organic waste that collects in lift stations. These solid blocks contain a high count of beneficial bacteria, which promote the natural degradation of organic materials. Regular use of Bio-Blocks helps maintain proper system function, reduces the need for manual cleaning or maintenance, and enhances the overall efficiency of the sewage system.

Simply suspend the environmentally-friendly Bio-Blocks into the treatment area to efficiently reduce sewer grease buildup, saving both time and money. Bio-Blocks are a key component of our proactive and highly effective grease control program.

Do not add to the treatment system at a location where toxic or otherwise adverse pH, dissolved oxygen or temperature conditions may exist at peak levels.

For optimal results the wastewater and treatment system should meet the following conditions:
Optimum Minimum
Influent pH 7.0 5.0
Dissolved oxygen, ppm 2.0+ 1.0+
C/N/P ratio 100/10/1 100/5/1
Temperature 30°C (86°F) 10°C (50°F)
Toxic metals, ppm
(E.g., hex., chromium)
0 0

Storage and Handling:

Storage: Store in a cool, dry place
Handling: Wash hands thoroughly with warm, soapy water after handling
