PEF pre-treatment for increased biogas potential in WWTP sludge

Evaluation of the pre-treatment effect of PEF (Pulsating Electric Fields) for increasing bio-methane potential in WWTP sludge.

Electroporation has been known for more than 50 years in the field of cellular research to form pores in the cell membranes, utilizing an electric field with rapid potential shifts. Within the last 10 years the technology has been used to improve the fermentation of sludge and other biomass materials, where the degradation of cell membrane and walls are vital. The effect on the methane potential is well documented, but so far the commercial breakthrough has not been achieved.

The company Arc Aroma Pure AB, based in Lund Sweden, has developed a technical platform (Closed Environment PEF Treatment; CEPT) that can apply the electroporation to substrates in industrial scale. The first industrial scale installations are up and running in both Klippan WWTP and in Helsingborg at the OX2 (Former NSR) biogas plant.

The assignment consists of evaluation and description of the capabilities of electroporation in regard to increasing the bio-methane potential in sewage sludge, primarily biological excess sludge.

The tasks included in the assignment will include sampling at one or more operational plants where the CEPT platform has been installed, as well as experimental work at the Arc Aroma Pure AB laboratory in Lund. The experiments include bio-methane potential tests (BMP), Continously Stirred Tank Reactors (CSTR) and evaluation of other parameters that can be affected by the treatment such as SCOD and VS.

Students in ecology systems, chemistry, biotechnology or other relevant background is encouraged to apply for this position. Recommended previous knowledge is VVA030 (Urban waters) or similar along with good laboratory experience. Drivers licens is an advantage but not a demand.

The start date of the assignment is perferably as soon as possible.

Företagsinformation

Arc Aroma Pure är ett företag som utvecklar, tillverkar, installerar och säljer utrustning för Pulserande Elektriska Fält (PEF) för biogas, matoljeextraktion, rening och flera andra applikationer. PEF på industriell skala är ett nytt koncept utvecklat av Arc Aroma Pure AB. Vi verkar inom ett brett teknologiområde med kunskaper framförallt inom elektronik och bioprocess, där vi jobbar med ny teknik och utveckling. Företaget växer fort och agerar globalt och under kommande månader och år kommer vi behöva förstärkning inom Bioprocesslabb, Elektronikkonstruktion, Programmering, PLC/Automation, Supply Chain, Kvalitet och säkert inom andra områden. Vi är precis i början av en fantastisk resa, vill du följa med?
