Treatment plant impacts


At the sewage treatment plant different cell signaling chemicals speed up microbial activity. Research shows that Biosol products can substantially increase both aerobic and anaerobic microbial numbers as shown in the graphs.






The graphs shown represent the most probable number of bacteria and are taken from heterotrophic (standard) plate counts.

It has long been known that if you increase the bacterial numbers, sewage process will be faster and more complete. The graphs show a substantial increase in both aerobic and anaerobic microbial numbers.

Current sewage treatment results show:
• Improved sewage process, as shown by improved Sludge Volume Index (SVI)

• Improved effluent quality (generally 20 - 30% reduction in BOD5 and SS),
• Reduced biosolid volumes (20 - 40% reduction).

Biosol has also recorded reductions in N&P in the effluent ranging from around 20%- 60%

The improved effluent quality ensures easier recycling, while the reduced biosolid volumes have an obvious benefit in terms of handling costs and greenhouse gas emissions.

Improved sewage process is likely to bring an overloaded sewage treatment plant back into specification and may defer sewage treatment plant augmentation at significant cost savings.
