The Challenge/Problem


Odors and FOG accumulation in Lift Stations and sewers causing frequent complaints and maintenance issues.

  • Odor issues at multiple lift stations and from sewer manholes.
  • Fat, oil and grease causing frequent maintenance visits to lift stations.
  • Solids accumulating in force mains and gravity sewers.
  • High cost of high-volume use of toxic inorganic chemical at pumping stations.
  • Low performance efficiency of inorganic chemicals to control odors.
  • Negative impact of odor control chemicals on biological performance of wastewater plants.
  • High odors in wastewater entering wastewater treatment plants

Treatment Plan
and Execution


Collection system engineers engaged SciCorp to solve odor and FOG issues. SciCorp recommended adding BIOLOGIC™ SR2 to the lift station wet wells to:

  • FOG crust layer in pretreatment lagoons reduced 85%–95%
  • BOD/COD removal in pretreatment lagoons increased from 40% to 85%
  • Odors eliminated from anaerobic pretreatment lagoons
  • BOD load to aerobic treatment, decreased by 85%
  • Sludge accumulation in sludge pond eliminated
  • Dredging of crust in anaerobic pretreatment lagoons eliminated

Problems Avoided


As a result of their partnership with SciCorp:

  • Odor complaints from adjacent property owners.
  • Installation of bio/chemical scrubbers at lift stations.
  • Negative impact of odor control chemicals on biological performance of wastewater plants.
  • Corrosion to piping and equipment reduced in lift station.
  • Negative impact on biological processes in wastewater plant elimination.

Success


Shortly after implementing the SciCorp treatment process, testing confirmed that odors had been eliminated from the lift stations and FOG issues had been dramatically reduced in lift stations and sewers.

Middle East Graph

H2S measurements in wet wells and
downstream manholes reduced 80 – 97%.

H2S in wet wells reduced from above 100ppm to below 10pmm in wet wells and WWTP inlet works.

FOG layer in wet well and trunk sewer/ force main inverts significantly reduced.

A significant reduction in Lift Station maintenance costs.

Odor complaints from workers and neighbors living close to lift stations were eliminated.

Odor and FOG from incoming wastewater to treatment plant dramatically reduced.

Ammonia and dissolved phosphorus levels were also reduced.

BIOLOGIC™ SR2 positively stimulated treatment at wastewater treatment plant.

Low dosage rate of BIOLOGIC™ SR2 eliminates need for large storage tanks and pumping system associated with inorganic chemicals used for odor control.

Accumulated sludge in wet wells and sewer mains “scooped out”.
