“…The algae species used in this study was M. aeruginosa because of its prevalence in algae blooms and relevance to water quality and treatment challenges in waterworks (Kemp and John, 2006;Sano et al, 2011). M. aeruginosa (strain FACHB-905), previously described by Shen et al (Shen and Song, 2007), was obtained from Wuhan Institute of Hydrobiology, Chinese Academy of Sciences, and cultured in BG-11 medium (Rippka et al, 1979).…”

“…1). In addition, the decrease in DOC values with elevation of chlorine doses from 0.4 to 2 mg/L after the further prolonged simulated transportation time of 240 and 480 min might be due to the ability of highly damaged algal cells to accumulate organic materials via adsorption (Marungrueng and Pavasant, 2006;Salima et al, 2013). This means that the serious damage to cyanobacterial cells is unfavorable for the continuous release of AOM into the dissolved phase.…”

“…2). The highly damaged algal cells have the ability to accumulate organic materials via adsorption (Marungrueng and Pavasant, 2006;Salima et al, 2013), due to their relatively large surface area and the physico-chemical adsorption process on cell surface (Tsezos and Bell, 1989;Tam et al, 2002;Aksu and Tezer, 2005).

a b s t r a c tThe prechlorination-induced algal organic matter (AOM) released from Microcystis aeruginosa (M. aeruginosa) cells has been reported to serve as a source of precursors for chlorinated disinfection byproducts (DBPs). However, previous studies have mainly focused on the precursors either extracted directly from the cell suspension or derived immediately after algal suspension prechlorination. This study aims to investigate the impacts of water transportation time after algal suspension prechlorination on cell integrity, AOM release, and DBP formation during the dissolved phase chlorination. The damage to cell integrity after prechlorination was indicated to depend not only on chlorine dose but also on transportation time. The highest dissolved organic carbon (DOC) and dissolved organic nitrogen (DON) values were observed at 2 mg/L chlorine preoxidation before transportation, but were obtained at 0.4 mg/L chlorine after 480-min simulated transportation. The variation of DON with transportation time was indicated to be mainly influenced by the small molecular weight nitrogenous organic compounds, such as amino acids. Additionally, formation of the corresponding chlorinated carbonaceous disinfection byproducts (C-DBPs) and nitrogenous disinfection byproducts (N-DBPs) during the dissolved phase chlorination showed the same variation tendency as DOC and DON respectively. The highest C-DBP (98.4 mg/L) and N-DBP (5.5 mg/L) values were obtained at 0.4 mg/L chlorine preoxidation after 480-min simulated transportation. Therefore, when prechlorination is applied for algae-laden water pretreatment, not only chlorine dose but also transportation time needs to be considered with regard to their effects on cell integrity, AOM release, and chlorinated DBP formation.

“…b-In biosorption isotherm modeling, the linearized Langmuir and Freundlich adsorption isotherms were applied according to Salima et al (2013) and Farah and El-Gendy (2013) where: C e /q e = 1/(Q e K L ) + (1/Q e ) C e (Ce) is the dye concentration in aqueous solution at equilibrium (mg/L), (q e ) is the experimental amount of adsorbed dye at equilibrium (mg/g), (Q e ) is the calculated amount of adsorbed dye at equilibrium (mg/g) and (K L ) is the Langmuir constant indicating the adsorption affinity of the binding sites (L/mg). Via plotting (C e /q e ) versus (C e ), (Q e ), and (K L ) can be determined from the slope and intercept of the obtained straight line respectively.…”

ATCH biosorption experiments were carried out for the removal of four dyes; Drimarene yellow CL4R (Y), Drimarene blue K2RL (B), Congo Red (CR) and Malachite Green (MG) from their aqueous solutions using two algal biomasses namely Gelidium latifolium (Grev.) Bornet et Thuret (red alga) and Ulva lactuca Linnaeus (green alga). The optimum conditions were applied in the treatment of eleven coloured industrial effluents from Borg El-Arab region, Egypt. Some modifications of the algal surface due to the bio-sorption process were noticed using SEM such as protuberance, wrinkle, shrinkage, stickiness, rupture and roughness. The bio-sorption process led to several band shifts that were detected using FTIR revealing the participation of C-N-S, alcoholic C-O, carboxylic C-O, carboxylic C=O, NH and OH groups in dyes bio-sorption. This bio-sorption was nonspontaneous, endothermic and chemical in nature. Freundlich isotherm model fitted slightly better than the Langmuir model indicating multilayer coverage (heterogeneous sorption). Utilization of C 2 H 5 OH for Y and B; NH 4 OH and HNO 3 for CR and MG, respectively was showed the most desorption efficiency for 4 reuse cycles of sorption-desorption. However, desorption and resorption efficiencies decrease with increasing the reusability cycle number. Ulva lactuca has shown much better dyes bio-sorption efficiency particularly with solid/liquid ratio: 1/1000 g/mL, initial dye concentration: 400 mg/L, temperature: 40° C, contact time: 1 hour, pH: 1, 2, 8 and 7 for Y, B, CR and MG, respectively. The applied decolourization of coloured samples reached 97.46 %.
