A large scale WWTP was experiencing high H2S levels in their sludge that was causing major odor issues. The WWTP manager requested that SciCorp conduct a third party laboratory controlled study to evaluate the ability of BIOLOGIC™ SR2 to control the sludge odors.
The Challenge/Problem
High levels of H2S and mercaptans in the sludge of a large Detroit WWTP were causing major odor issues for the plant and surrounding neighbors. Specific issues included:
Testing protocol
Independent Odor Assessment Results (ORTECH)
BIOLOGIC™ SR2 was found to out-perform all other competing products during all tests that were carried out.
All other mercaptans were reduced to the detection limit of the measurement instruments following treatment of the sludge with BIOLOGIC™ SR2.
82%
Reduction
BIOLOGIC™ SR2 was
