Bio-Blocks reduce odor, sludge, fats, oils and grease in your lift stations

FOG (fats, oil, and grease) from homes, restaurants, and other commercial and industrial facilities enters collection systems and accumulates in sewer lines and lift stations.

Sewer grease buildup in lift stations leads to clogging, reduced pump efficiency, increased maintenance, and foul odors.

Bio-Blocks break down FOG and other organic wastes that collect in lift stations. The high quality, high count beneficial bacteria in these solid blocks promote the natural degradation of organic materials. Bio-Blocks help support proper functioning, reduce the need for manual cleaning or maintenance, and improve the overall efficiency of the sewage system when used regularly in lift stations.

By simply suspending the environmentally friendly Bio-Blocks into the treatment area, you will maintain lift station efficiency by decreasing sewer grease buildup, saving time and money.

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
