TI  - Removal of inhibitory phenolic compounds by biological activated carbon coupled 
      membrane bioreactor.

AB  - Phenolic compounds cause problems for conventional treatments due to their toxic 
      and inhibitory properties. This work investigated the treatability of phenolic 
      compounds by using two membrane-bioreactor systems, namely: activated sludge 
      coupled with MBR (AS-MBR) and biological granular activated carbon coupled with 
      MBR (BAC-MBR). Initially, the system was fed with phenol (500 mg/L) followed by 
      adding 2,4-dichlorophenol (2,4-DCP). Phenol, 2,4-DCP, TOC and COD removal were 
      higher than 98.99% when the organic load ranged between 1.80 and 5.76 kg/m3.d 
      COD. In addition to MBR system development, removal mechanisms were also 
      investigated. Relatively low values of phenol adsorption of GAC and biomass, and 
      high maximum substrate removal rates obtained from a biokinetic experiment, 
      proved that the removals were mainly due to biodegradation. Analysis of sludge 
      indicated a significant difference in the sludge characteristics of the two 
      reactors. The high EPS content in BAC-MBR led to higher viscosity and poor sludge 
      settling properties. The relationship between sludge properties and EPS 
      components revealed that settleability had no direct correlation with EPS, though 
      it was better correlated to protein/carbohydrate ratios.
