Editorial
Fifth issue of Algerian Journal of Engineering Research: Process Engineering for the solution of chemical, pharmaceutical and environmental problems
The retained nine papers for the fifth issue of the Algerian Journal of Engineering Research (AJER) concerned various interesting Process Engineering studies.
The first paper was concerned with the hydrothermal synthesis of a new hybrid material from β-cyclodextrin (β-CD) and activated carbon (AC), exploiting the fact that hybrid carbon material with several oxygen-containing functional groups like -C=O-, -OH, etc., can be well-dispersed on the surface and at the entrance of the pores of AC. The obtained carbon composite exhibited a remarkably enhanced adsorption capacity for Pb (II), for instance, doubling that of non modified AC (Yahiaoui et al.).
The second paper dealt with the study of the ability of inorganic-organic pillared clays to adsorb basic yellow (BY28) and humic acids (HA) from wastewater at ambient temperature of 20 °C. The results showed that, individually, BY28 was adsorbed more rapidly than HA. However the retention rates were improved for binary systems (BY28-HA) at different molar ratios comparatively to cases of single solute systems. Isothermal data was predicted from binary systems using single-component data, by means of Sheindorf-Rebhun-Sheintuch (SRS) model: However this had limited success due to the competitive and interactive effects between dye and humic acids (Zermane et al.).
The third paper, similarly to the two previous ones, dealt with a sorption process where a natural, low cost and abundant material, namely Reed, proved to be an effective sorbent for the removal of lead(II) from aqueous solutions (Boudrahem and Aissani-Benissad).
The next paper still concerned the elimination of a pollutant consisting of an endocrine disrupter (BPA) by degradation by means of an advanced oxidation process (POA) based on solar photocatalysis. A degradation rate of 93% was obtained after 90 minutes confirming the performance of the solar ZnO/UV system. The study confirmed the performance of the semiconductor ZnO used as a photocatalyst (Hachi et al.).
The fifth paper concerned a submerged Membrane Bioreactor (sMBR) where the fraction of active biomass of activated sludge was identified and quantified involving respirometric analyses and Activated Sludge Model (ASM). Also heterotrophic biomass (XBH), autotrophic biomasses responsible of nitrite (XBAI) and nitrate (XBAA) productions, had been quantified within activated sludge fed with soluble and easily biodegradable substrate (ethanol/sodium acetate (1:1)). This led to the generation of a sludge constituted essentially of two fractions: XBH and XBA. The results showed the growth of this specific biomass under high SRT and substrate limited conditions (Benaliouche et al.).
The next paper dealt with the optimization of a tangential microfiltration system, investigating the effects of operating conditions such as the pressure, the filtration time, the characteristics of the raw water (the material in suspension), their interactions on the permeate flux and the total resistance to fouling by the use of Minitab software (version 16) to determine the optimum during the production of drinking water (Boussemghoune et al.).
The seventh paper reports the study of a microbiological characterization of the leachate resulting from the degradation of waste stored in an open-air discharge. The leachates were rejected to the external environment without any pretreatment, hence the negative impact on the microbiological quality of waters issuing from two model wells (40-50m deep). The obtained results confirmed that these leachates contained more than 30×105 and 4×105 cfu/ml of enterobacteria and total coliforms, respectively with the presence of staphylococci, streptococci and even salmonell. These leachates and well waters presented a poor microbiological quality, comparatively to the Algerian standards (Mansouri et al.).
The next paper dealt with the incineration of hospital wastes and particularly the bottom ash which have complex composition and cannot be disposed off in any way in landfills. However the valorization of this ash as discoloring agent of wastewaters effluents from the textile industry which is a great dyes user, had been considered. Important treated water quantities could be obtained and recycled. As an example performing results were obtained for the removal of Gentian Violet, achieving 98.82% for a contact time of one minute, an L / S ratio: 0.3 ml mg-1, a stirring speed of 850 rpm, a temperature of 20 ± 5 °C. However this bleaching ability could not be achieved for the different bottom ashes collected from five different hospitals (Zamouche et al.).
The last paper was concerned with the development of a liposomal suspension encapsulating a non-steroidal anti-inflammatory which will constitute the dispersed phase of a gel for dermic use. For instance Diclofenac preparations for dermal applications exist only under the gel and emulgel forms. Therefore a liposomal form was proposed in order to increase the skin penetration or even the availability of Diclofenac due to the phospholipid bilayer of the liposome having the same structure as the skin. The liposome formulation was based on soy lecithin, cholesterol, by the inverse phase evaporation method then optimized and characterized. The influence of the excipients used in the basic formulation on certain physicochemical properties (particle size distribution and zeta potential) of the system, was investigated. An optimization based on the response surface methodology led to the optimum of ethanol amount in relation to water combined with maximum levels of cholesterol and lecithin. This promoted the production of small-sized liposomes with a relatively high surface charge (zeta potential) and only a narrow polydispersity, thus meeting the stability criteria favoring transposition to an industrial scale (Gherrak et al.).
Through these papers one can see how to manipulate process engineering to tackle different applications, be they chemical, pharmaceutical, medical, environmental, etc.
