## Abstract The treatment of phenolic wastewater was investigated in a gas–liquid–solid fluidised bed bioreactor containing polypropylene particles of density 910 kg m^−3^. Measurements of chemical oxygen demand (COD) versus residence time (__t__) were performed for various ratios of settled bed vo

The operating parameters for a gas-liquid-solid fluidised bed bioreactor with a low density (matrix particle density smaller than that of water) biomass support were investigated. In particular, the ratio of bed (settled) volume to bioreactor volume (V b /V R ) and the air velocity U, for which the
## Abstract Aerobic treatment of refinery wastewater was carried out in a 200 dm^3^ gas–liquid–solid three‐phase flow airlift loop bioreactor, in which a biological membrane replaced the activated sludge. The influences of temperature, pH, gas–liquid ratio and hydraulic residence time on the reduct
