Creating environmentaly sustainable waste / wastewater treatment system
methane-rich biogas , while UF membranes create a high-quality effluent that is discharged into the municipal sewer system .
THE CHALLENGE
Jack Link ' s , a leading protein snack producer , was in need of a water treatment solution at its facility in Alpena , South Dakota . Jack Link ’ s previous wastewater treatment system consisted of a Dissolved Air Flotation ( DAF ) system for FOG ( Fats , Oils , & Grease ) and TSS reduction . Effluent from the system was discharged directly to the sewer system , and the city municipal treatment plant was becoming overloaded as a result of the facility ’ s production increases and high BOD loads .
THE SOLUTION
Veolia Water Technologies partnered with Jack Link ’ s to develop a process that would solve the facility ’ s high BOD discharge issue , while simultaneously creating biogas as a byproduct to reduce the plant ’ s energy costs .
Veolia ’ s treatment process utilizes Memthane ® Anaerobic Membrane Bioreactor ( AnMBR ) technology combined with a Sulfothane™ Biogas Desulfurization System . Memthane pairs anaerobic biological treatment with ultrafiltration ( UF ) membranes to create an industry-leading anaerobic membrane bioreactor system . The bioreactor converts the plant ’ s waste into a
Biogas from the Memthane system is then treated by Veolia ’ s Sulfothane system . This treatment step removes sulfur compounds from the biogas , which are highly corrosive and can damage downstream equipment . The scrubbed biogas is then sent to a Combined Heat and Power ( CHP ) Generator , creating onsite electricity and offsetting energy costs .
THE RESULT The Memthane and Sulfothane systems have exceeded performance and client expectations . Final permeate discharge from the Memthane system averaged less than 100 ppm BOD for greater than 98 % BOD removal rates . Membrane operation during the first 24 months of operation was stable , with flux rates ranging from 9 to 18 lmh .
The Sulfothane system was able to reduce the biogas ’ s H 2
S levels from 6,000-8,500 ppm to less than 10 ppm , which is well below the generator ’ s manufacturer specifications .
Due to sustained process stability and consistent high quality effluent , the city treatment plant operation has improved greatly .
ENERGY POSITIVE WASTE / WASTEWATER TREATMENT PLANT
The system is not just energy efficient , it is also energy positive when operating at full flow . The biogas byproduct currently produced in the anaerobic reactor generates more electricity than the system consumes . The result is a fast return on investment for the capital purchase . ●
