“…Owing to the toxic nature of phenol, it is placed under priority list of pollutants that need to be treated before releasing the wastewater to the aquatic ecosystems. The total phenol in refinery wastewater has been estimated to be 13-88 mg/l (Abdelwahab et al 2009;Jou and Huang 2003;Ojumu et al 2005;El Naas et al 2010). Conventional phenol removal techniques include solvent extraction, adsorption, coagulation and chemical oxidation.…”

A phenol-degrading novel diatom BD1IITG was isolated from petroleum refinery wastewater and characterized (GenBank Accession No. KJOO2533). HPLC analysis showed the diatom could degrade phenol in the concentration range of 50-250 mg/l in Fog's media. The highest specific growth and degradation rate were achieved at 100 mg/l phenol. It could also mineralize phenol along with aliphatics in petroleum refinery wastewater. Growth kinetic modeling shows that Haldane model best represents the growth behavior of the diatom in nutrient media as well as refinery wastewater. Biokinetic parameters suggest that the diatom possesses higher maximum specific growth rate (l max = 0.4 day -1 ), better tolerance to toxicity (K I = 90.24 mg/l) and high phenol affinity (K s = 20.99 mg/l) in refinery wastewater as compared to Fog's media confirming practical applicability of the strain for wastewater treatment. FTIR fingerprinting of biomass indicates intercellular phenol uptake and breakdown into its intermediates via phenol degradation pathway. Pathway was elucidated using HPLC, LC-MS and UV-visible spectrophotometry confirming prominence of ortho-over meta pathway for phenol metabolism. The diatom produces biosurfactant with highest emulsifying activity at 100 mg/l phenol which may contribute to highest degradation rate at this concentration. Infrared analysis confirms increased biosynthesis of lipids and polysaccharides in phenol-degrading biomass, indicating its potential use as feedstock of clean ecofriendly energy sources as biodiesel or bioethanol. The phenol degradation capability coupled with potential applicability of the spent biomass as biofuel feedstock makes diatom BD1IITG a potential candidate for a clean environmentally sustainable process.

“…1(a) and (b). Nano-bioadsorbents surface area was determined according to BrunauerEmmett-Teller Method (BET) by using Tristar 3000 Micromeritics device (Micromeritics Instrument Corp., USA) [20,21]. The results of BET method showed that average surface area of Aloe vera and Mesquite nanoparticles were 41.25 and m 2 g -1 and 38.76 m 2 g -1 ,…”

This study was performed to measure the potential utilization of agro-waste to generate nanoparticles and evaluate the capability of it's as a low cost adsorbent for removal of phenol. Adsorption studies for phenol removal by using Aloe vera and Mesquite leaves nanoparticles carried out under various experimental conditions including pH, nanobioadsorbent dosage, phenol concentration, contact time, temperature and ionic strength in a batch reactor. The adsorption kinetics by pseudo-first order and pseudo-second order models and isotherm technique by Freundlich and Langmuir isotherms models were applied. The results showed that the rate of phenol adsorption increases in both nano-bioadsorbents with an increase of pH up to 7, adsorbent dosage up to 0.08 gL -1 , phenol initial concentration up to 32 mgL -1 , contact time up to 60 min and raising in temperature. The adsorption data followed the Freundlich isotherm model. The kinetic studies indicated that the adsorption of phenol with nano-bioadsorbents was best described by the pseudo second order kinetics. We found that the nanoparticles prepared from Aloe vera and Mesquite leaves had a high capability in adsorption of phenol, beside the point that they could be accessed at a low cost. These agrowastes can be used to remove phenol from aqueous environments.

“…However, most of these physiochemical methods sufer from noticeable drawbacks such as high capital and operating costs. Ultimately, most of them do not destroy the contaminant, but rather transfer it to another phase, which results in the formation of harmful by-products [13,16]. Formation of chlorinated organic compounds has been reported during some electrochemical applications, and activated carbon adsorption was recommended as a further polishing treatment to remove them [5,12].…”

“…During the adsorption, phenol is not degraded but rather transferred from the RWW to another phase, which results in the formation of serious by-products (secondary pollution). As such, regeneration is essential for reusing the activated carbon and for the collection and reuse of the contaminant substance [14,16]. Activated carbon is characterized by a wide variety of pores.…”

Addressing major environmental issues, such as water pollution, is essential nowadays in realizing sustainable development. The ever-increasing world population and industrial development have led to the introduction of diferent types of chemicals to the environment, leading to considerable deterioration in environmental quality. A major class of these chemicals is phenolic compounds, which are hazardous pollutants and highly toxic even at low concentrations. In recent years, researchers have realized the importance of extracting new bacterial strains that are efective in treating diferent types of highly contaminated wastewaters at diferent severe conditions. They also focused considerable amount of research on developing new types of reactors that would provide eicient mixing and reduce mass transfer limitations. The aim is to develop and evaluate efective reactor systems and biocatalysts for the biodegradation of major contaminants in petroleum reinery wastewater. This chapter examines the diferent available options for the treatment of reinery wastewater with more focus on novel biotreatment options.
