“…Among them, phenol is one of the crucial pollutants present in wastewater released at noticeable levels. The concentrations of phenol in wastewater released from various industries are listed in Table 1 ( Polat et al 2006;Ucun et al 2010). The inclusion of a wastewater management and pollution control target is, therefore, an essential component of any future water agenda (Karnib 2014).…”

In this paper, the feasibility of the dry stem of Lantana camara waste as an adsorbent to remove phenol from aqueous solution was investigated in a packed-bed column. The effect of bed height (5, 10, 15 cm), initial phenol concentration (100, 150, 250 mg L ) on the adsorption were studied by evaluating the breakthrough curves. The following models were used to assess the column performance: Thomas, Adams-Bohart, Yoon Nelson, Modified dose-response, linear driving force model based on fluid phase concentration difference (LDFC) and linear driving force model based on particle phase concentration difference (LDFQ). The Thomas model and the LDFC model were in good agreement with the experimental data. The bed depth service time (BDST) model was used to predict adsorption performance at other experimental conditions. The maximum adsorption capacity was found to be 149.77 mg g −1 , confirming that Lantana camara is a suitable adsorbent for the removal of phenol from aqueous solution.

A mathematical model was developed to describe the reduction of Cr(VI) by Escherichia coli (E. coli) 33456 in a fixed biofilm reactor. A laboratoryscale column reactor was conducted to verify the model system. The batch kinetic tests were independently conducted to determine the biokinetic parameters used in the model simulation. With the assumed values of initial biofilm thickness (L f0 ), the mathematical model simulated well the experimental results for Cr(VI) effluent concentration, effluent concentration of suspended E. coli cells, and Cr(III) production. The concentration of suspended E. coli cells reached up to 1.2 mg cell/L while the thickness of attached E. coli cells was estimated to be 32.6 lm at a steady-state condition. At the steady state, the removal efficiency of Cr(VI) was about 92 % and the effluent concentration of Cr(III) was approximately 1.6 mg/L. The approaches presented in this study can be employed for the design of a pilot-scale or full-scale fixed biofilm reactor to treat Cr(VI)-containing wastewater.

“…The jet of liquid from the nozzle produces high mixing and turbulence that supplies the optimal mass transfer and good treatment efficiency. JLBRs have some advantages such as small reactor volume, low costs for installation and maintenance and high treatment efficiency (Ucun et al, 2010). However, the solid-liquid separation is a significant problem in JLBRs.…”
