Natural polymers have proven to be extremely interesting matrices for the immobilization of microbial biomasses, via various mechanisms, in order to bring them into a form easier to handle—the form of composites. This article aimed to study composites based on a residual microbial biomass immobilized in sodium alginate via an encapsulation technique as materials with adsorbent properties. Thus, this study focused on the residual biomass resulting from beer production (Saccharomyces pastorianus yeast, separated after the biosynthesis process by centrifugation and dried at 80 °C)—an important source of valuable compounds, used either as a raw material or for transformation into final products with added value. Thus, the biosorptive potential of this type of composite was tested—presenting in the form of spherical microcapsules 900 and 1500 μm in diameter—in a biosorption process applied to aqueous solutions containing the reactive dye Brilliant Red HE-3B (16.88–174.08 mg/L), studied in a batch system. The preparation and characterization of the obtained polymeric composites (pHPZC, SEM, EDS and FTIR spectra) and an analysis of different equilibrium isotherms (Langmuir, Freundlich and Dubinin-Radushkevich—D–R) were investigated in order to estimate the quantitative characteristic parameters of the biosorption process, its thermal effects, and its possible mechanisms of action. The modelling of the experimental data led to the conclusion that the studied biosorption process took place after reaching the Langmuir isotherm (LI), and that the main mechanism was possibly physical, being spontaneous and probably exothermic according to the values obtained for the free energy of biosorption (E = 8.45–13.608 kJ/mol, from the DR equation), as well as the negative values for the Gibbs free energy and the enthalpy of biosorption (ΔH0 = −87.795 kJ/mol). The results obtained lead to the conclusion that encapsulation of this residual microbial biomass in sodium alginate leads to an easier-to-handle form of biomass, thus being an efficient biosorbent for static or dynamic operating systems for effluents containing moderate concentrations of reactive organic dyes.

Despite of immense application potential of graphene in wastewater treatment, the colloidal stability, aggregation and recyclability remains a major challenge. To address this issue, we report biomaterial functionalized graphene-magnetite (Bio-GM) nanocomposite as a novel recyclable material for treatment of wastewater containing dyes and heavy metals. The integration of biomaterial including living cells of Shewanella oneidensis with graphene-magnetite nanocomposite was characterized through UV–vis, FTIR, FESEM and fluorescent microscopic studies. The contact angle measurement depicted the hydrophilic property (water contact-angle 27.93°), whereas VSM result demonstrated super paramagnetic behavior of the nanocomposite with saturation magnetization value of 30.2 emu/g. The Bio-GM nanocomposite exhibited excellent adsorption capacity toward dyes and Cr6+ in both single and multicomponent system with removal capacity of 189.63 ± 7.11 and 222.2 ± 8.64 mg/g of dyes and Cr6+, respectively, suggesting selective binding capacity and high adsorption efficiency of Bio-GM nanocomposite. In the adsorption coupled redox reaction, the Cr6+ was reduced to Cr3+ through biocatalytic activity of Bio-GM nanocomposite. The nanocomposite could be easily regenerated and reused for multiple cycles of adsorption–desorption studies without release of graphene and magnetite, and thus eliminating the potential hazardous risk of nanomaterial to the environment. The proposed biomaterial functionalized graphene-magnetite nanocomposite thus offers a novel way for sustainable, affordable, and efficient removal of coexisting toxic pollutants of dyes and heavy metals.

“…Biological process cannot remove dyes because of their inorganic form and toxicity to the microorganisms used in process (Gosavi and Sharma 2013). Therefore, the treatment of wastewater contaminated with color has an important role in preventing environmental pollution (Saravanan, et al 2013). The application of effective with low cost and high efficiency technology is very important.…”

The endek industry produces low-biodegradable wastewater, which is very difficult to treat using the biological methods. For this reason, this study was aimed at improving the quality of wastewater for endek textile wastewater using the combination of ozone oxidation process as pretreatment and anoxic-aerobic activated sludge. The ozone reactor volume amounted to 3L and the applied ozone dose equaled 0.05 mg/minute. The BOD/COD of endek wastewater increased to 0.38 after ozone treatment and the application of anoxic-aerobic activated sludge treatment. The anoxic-aerobic experiments were conducted in batch process and consisted of activated sludge. Conventional anoxic-aerobic treatment can reach color and COD removal of 30% and 32%, respectively, without pre-treatment. The ozone pretreatment can increase color and COD removal up to 76.6% and 86.9%, respectively. On the basis of the effluent standards of textile wastewater quality, COD, BOD 5 , and total ammonia (NH 3-N) parameters have met the quality standards.
