Methology
SCD Bio Klean™ is added to sludge separated from the system. A fraction of ammended sludge is
recirculated to the general system improving the characteristic of the outflow water.
Results
All goals were achieved.
Significant improvement in all outflow parameters (except Nitrogen content) occurred after the
SCD Probiotics applications, as evidenced in Table I below.
In addition, the following benefits were achieved as a result of the SCD Probiotics application,
positively impacting the operational and financial performance of the waste water treatment facility.
- Elimination of PIX application (a coagulation agent).

- Cost reductions:
– 200.000 PLN from disposal cost reduction per annum
