Item Advanced biosorbents materials for removal of chromium from water and wastewaters(American Institute of Chemical Engineers, 2011) Sahmoune, Mohamed Nasser; Louhab, Krim; Boukhiar, AissaItem Biodegradation of diclofenac by activated sludge and membrane bioreactor-a review(Aljest, 2015) Cherik, Dalila; Louhab, KrimDiclofenac (DCF) is a pharmaceutical residue of therapeutic class of non-steroidal anti-inflammatory which is often detected in the wastewater treatment plants (influent and effluent) and surface waters. This review focuses its elimination by biodegradation with activated sludge (CAS) or bioreactor membrane (MBR) in which microorganisms plays a key role in the elimination of diclofenac and in which a lot of factors can affect the efficiency of the removal as physicochemical properties of diclofenac, sludge retention time (SRT), temperature, pH, redox conditions and sludge characteristics.The objective of this study was to describe a review of the literature by recent publications on the biodegradation of diclofenac. We inspect the performance of biodegradation using biological process technology by activated sludge and membrane bioreactor in the elimination of diclofenacItem Comparative LCA of reconstituted milk and recombined milk processing(2012) Younsi, Farroudja; Louhab, Krim; Belblidia, ChawkiItem Comparative study of the adsorption of paracetamol from aqueous solution on olive stones and date pits(Taylor & Francis, 2018) Medjdoub, Fatma; Louhab, Krim; Hamouche, AksasItem Dust exposure in foaming workshop, case of the home appliance industry in Algeria(SJR, 2018) Rebbah, Hakima; Akachat, Amina; Louhab, KrimThe framework of the present paper was to evaluate the exposure to dust pollution and aerosols of the polyurethanes foam intended for the thermal insulation of refrigerators. Based upon the worker`s complaints and investigations done in collaboration with occupational physicians; four testing stations were set up to evaluate the air quality at the gates injection (GI), tanks injection (TI), tank cleaning (TC), and the workshop atmosphere (WA). Two sampling techniques were used. The first was to use the rotary cup individual sensor flow dust of 10 l/min (CIP 10), with three fractions selectors; alveolar, thoracic and inhalable to evaluate the weight concentration. The second technique was using impregnated filters to sample and analyze the identified aerosols. For the samples taken in the (TC) station using the (CIP10), the results have shown that the air in the worker`s breathing area contains 2.6 mg/m3 for the alveolar fraction, 1.33 mg/m3 for the thoracic fraction and 5.33 mg/m3 for the inhalable fractions. In the (WA) station we have got 3.3 mg/m3 for the alveolar fraction; 8.6 mg/m3 for the thoracic fraction and 7.33 mg/m3 for the inhalable fraction. The qualitative analysis of the aerosols through the filter sampling has confirmed the presence of the 4,4-Methylene diphenyl diisocyanate (4,4-MDI) in the workshop atmosphere. This research confirmed through the obtained results that operators are exposed permanently during their working hours to both pollutions dust and aerosols of 4,4-MDIItem A kinetics, isotherms, and thermodynamic study of diclofenac adsorption using activated carbon prepared from olive stones(2017) Cherik, Dalila; Louhab, KrimItem Preparation of microporous activated carbon from date stones by chemical activation using zinc chloride(Taylor & Francis, 2017) Cherik, Dalila; Louhab, KrimItem Studies of chromium removal from tannery effluents by dead streptomyces rimosus(2008) Sahmoune, Mohamed Nasser; Louhab, Krim; Boukhiar, AissaItem Using life cycle assessment methodology to assess human health and ecosystem toxicity impacts associated with milk production in algeria(PSP, 2017) Younsi, Farroudja; Louhab, KrimItem Valorising waste biomass from aromatic and medicinal plants to produce steam for the extraction of essential oils(Taylor & Francis, 2023) Ben Bouabdallah, Amina; Aksas, Hamouche; Kouini, Benalia; Louhab, KrimBiomass residues from the aromatic and medicinal oil extraction industries were used as fuel to produce steam necessary for the extraction of essential oils (EO) by hydrodistillation from a plant around the Mediterranean, Daucus carota L. The results obtained in terms of yield and extraction time were compared to those obtained by the classical method of hydrodistillation (HD) using electric heating. Several advantages with hydrodistillation in the presence of biomass as an energy source (BEHD) have been observed: faster kinetics and higher efficiency with similar yields: 1.03% and an extraction time of 30 min against 180 min for classic hydrodistillation. The antimicrobial activity and the antioxidant activity of the EO extracted by HD and BEHD were evaluated. The results showed that the oil extracted by BEHD has a better antioxidant activity and it is much more active than that isolated by HD.
