“…Conversely, reports of NA bioremediation often conclude that NAs of lower molecular weight, with fewer rings and branching, are more readily biodegraded by microbial cultures, leaving higher molecular weight NAs unmetabolized [64][65][66]77]. Further, coagulation/flocculation processes are often cited as significant producers of sludge [85,88,91], while fouling and poor selectivity are frequent challenges for both membrane filtration and adsorption processes [91,92]. Given the apparent limitations of these individual processes, much of the emerging research in this field is directed toward the treatment of OSPW using a combination of techniques [76,94,97,98,110,113].…”

“…Several of the reviewed papers report on cost reduction [73,85,106,108,109], improved energy efficiency [49,53], and higher throughput [70,72,92], characteristics of a process that ultimately determine its industrial applicability. That being said, major strides must be made for many of the proposed technologies to realize its full-scale implementation.…”

“…Peng et al [92] explored the use of three commercial polymeric nanofiltration membranes, Desal 5 (GE Osmonics), NF45 (Dow Chemical), and NF90 (Dow Chemical), for the softening and removal of NAs from OSPW supplied by Syncrude Canada Ltd. Depending on the OSPW source, the concentration of NAs ranged from 6.6-57 mg L À1 .…”

“…advanced oxidation, biodegradation, flocculation, typically requires months or, in some cases, years to purify the water to an acceptable level of dissolved compounds [66,79,91]. The high throughput of membrane filtration technologies may help to expedite the reclamation process [92].…”

“…An apparent limitation of many membrane filtration processes is fouling [92]. Fouling not only causes reductions in permeate flux, but may also cause reductions in the removal efficiency of the membrane [88].…”

Produced water can be defined as water present in a formation with, and brought to the surface with, crude oil or natural gas. More than 87 B barrels of produced water are generated globally each year, constituting the largest wastewater stream generated from petrochemical exploration and production. This amount is expected to grow over the next several years. Increased water demand and tighter regulations are leading to more produced water treatment. Membranes have recently attracted attention for removal of suspended solids, organics and dissolved solids. This article reviews the use of membranes for produced water treatment.

Removal of 2‐naphthoxyacetic acid from aqueous solution using quaternized chitosan beads

2016

The present study investigates the use of quaternized chitosan hydrogels for the adsorption of an aromatic organic carboxylate, 2‐naphthoxyacetic acid (2‐NAA), to demonstrate the applicability of this type of adsorbent towards the removal of naphthenic acids (NAs) from oil sands process‐affected water (OSPW). The effects of varying three processing parameters on the physical and adsorption characteristics of the resulting adsorbents were investigated, namely the density, degree of cross‐linking, and degree of quaternization of the hydrogel beads. Their effects on the swelling behaviour and Langmuir adsorption capacity of 2‐NAA were reported. The Langmuir adsorption isotherm provided adequate fit for the equilibrium adsorption data (R2 ≥ 0.99), while the pseudo second order rate equation described the kinetic adsorption data quite well (R2 ≥ 0.95). The effects of adsorbate concentration, adsorbent dosage, agitation rate, ionic strength, pH, and temperature on the adsorption process were also studied. At the initial concentration of approximately 200 mg/L, up to 91 % of 2‐NAA was adsorbed. The best quaternized chitosan hydrogel adsorbents reported in this study possessed a maximum adsorption capacity of 315 mg/g.
