In other cases, little, if any effect of sulfate concentra- tion on anaerobic reactor performance was observed (Choi and Rim, 1991; Henry and Prasad, 2000). The highest CODr

Within this context, the present study strived to achieve, through implementation of several opera- tional strategies, stable production of hydrogen from cheese whey wastewater,

Abstract - This paper investigates the simultaneous removal of arsenic [As(V) or As(III)] and manganese [Mn(II)] from natural waters of low and high turbidity by clarification

The bacterial community present in each sludge sample was evaluated previously using the assays in Table 1 before adding the medium and the hormones dissolved in methanol..

Besides obtaining the numerical results for the behavior of the temperature of the ceramic tile dur- ing the firing operation in an industrial roller kiln, the proposed model is

The enhanced heat transfer in tubes under laminar flow with induced mixing by the presence of coils, corrugated walls, curves, pipe fittings, high relative wall toughness

  The sedimentation velocity of droplets in a complex system composed of water-in-crude oil emulsion were investigated in a laboratory scale unit, monitoring the water droplet

BET surface area analysis and differential thermal analysis (DTA) were used to assess changes in the structure of the catalyst caused by electrokinetic treatment.. Regarding the
