Bioreactor

PEEK-WC HF bioreactor permits us to reproduce the Hypericum perforatum immunomodulatory effect on human peripheral lymphocytes as observed by previous in vivo studies. In fact, St. John’s wort modulates linfocitary response suppressing metabolic activities. This investigation underlines the ability

One way to produce fuel gases is using bioreactors producing CH4/CO2, H2/CO2 and CH4/H2/CO2 gas mixtures. This method has many advantages; for example, low energy consumption, high ecological efficiency, utilization of organic wastes, accessibility and simplicity of hardware implementation. The resu

Studies have been conduced on a groundwater containing 850–1100 mg/l of total dissolved solids (TDS) and 80 mg/l of nitrate to remove nitrate by coupling electrodialysis and bioreactor. The performances of the pilot plant during the period of the tests (more than one year) were proved. The optimisat

This paper presents a study that aims to overcome oxygen limitations in membrane-attached biofilms in the Extractive Membrane Bioreactor (EMB), by using nitrate instead of oxygen as an electron acceptor. In the EMB target organic compounds are extracted through a dense membrane into a bioreactor, wh

Partial nitrification is required before transporting secondary treated wastewater by pipe, which is common in most schemes of wastewater reclamation for irrigation. Sulfide, generated in the anaerobic conditions of the pipe, induces toxicity, corrosion and unpleasant odours. However, a low nitrate
