“…According to RMSE, PFO kinetics are not able to reproduce the experimental values observed while PSO kinetic represent the kinetic data with a low error. This behaviour is commonly found in the bibliography [11,18,19] and confirms that the PSO model is more consistent since adsorption capacity governs the adsorption rate and is not the adsorbate concentration [20]. Ammonium adsorption takes place in three phases: first of all, ammonium is diffused from the liquid phase to a liquid-solid interface, after which the ammonium in the liquid-solid interface moves to a solid surface, and finally, ions diffuse into the particle pores [16].…”

Anaerobic Membrane Bioreactor technology has great advantages for treating wastewater, including energy recovery from organic matter. However, when the legislation requires that effluent standards be met in sensitive areas, this treatment cannot remove the nutrients, thus the permeate generated needs post-treatment. Apart from the biological processes, ion exchange is an alternative treatment for this stream since it can remove nutrients and concentrate them for later recovery as fertilizers. In this work, the feasibility of using a natural zeolite (clinoptilolite) for treating NH4 from AnMBR permeate was studied and tests were carried out on the adsorption kinetics of ammonium. Isotherm tests verified that activating natural zeolite to its -Na form improves its performance by 20% and increases qe from 2.37 to 2.86 mg NH4-N/g for a Co of 30 mg NH4-N/L. It was also found that the cations present in the water (especially Ca2+ and Na+) caused a 22% reduction in ammonium adsorption while organic matter was responsible for improving the retained ammonium by 22%. It was also found that the working pH (7.2 ± 0.2) is close to the optimal pH range (6–7) for zeolite performance. The tests on the AnMBR permeate indicate that clinoptilolite is a suitable material since treating this stream can retain up to 7.44 mg NH4-N/g.

“…The physical method is the basic method of separation, recovery, or treatment of phenol-containing wastewater, and the common physical methods include adsorption, liquid membrane separation, and extraction. Among them, the adsorption method is the use of adsorbent developed pore structure, large specific surface area and pore capacity, surface functional groups and other characteristics, adsorption recovery, or removal of phenolic substances in water method. , Adsorption methods can be divided into physical adsorption, chemical adsorption, etc. In principle, the adsorption of pollutants can be carried out through hydrogen bonding, van der Waals forces, and other forces .…”

Biomass waste and wastewater are important wastes in the process of industrialization, which need to be effectively treated and utilized. In this work, an innovative method of collaborative treatment of biomass waste and phenol-containing wastewater is proposed. Biomass waste was used to produce activated carbon (AC), and then AC was used for phenol removal in wastewater treatment. Two kinds of typical biomass waste material, namely, coconut shell and lignin, were used. Physical activation (steam activation) and chemical activation methods were compared. Results show that steam activation is an effective method for coconut shell AC production. The largest Brunauer−Emmett−Teller (BET) surface area was 1065 m 2 /g at 800 °C. Chemical activation could produce AC samples with higher BET specific surface area. The lignin AC with K 2 CO 3 activation has the largest BET surface of 1723.8 m 2 /g at 800 °C. FTIR results indicated that K 2 CO 3 activation could greatly enhance the formation of surface oxygen-containing functional groups. Both coconut shell AC and lignin AC samples show excellent performance for phenol removal. The highest phenol removal efficiency for coconut shell AC and lignin AC are 96.87% and 98.22%, respectively. Adsorption kinetic analysis show that the pseudo-first-order kinetic model is able to describe the adsorption characteristics of phenol in wastewater treatment. Recycling properties show that regeneration of lignin AC could maintain high adsorption performance for phenol.

“…Among the phenolic compounds present in OMW, tyrosol is one of the major compounds, being recognized for its antioxidant, anti-inflammatory, and antimicrobial properties. Therefore, its recovery is of great interest for its future commercialization in cosmetic, food, and pharmaceutical industries [ 4 ].…”

Currently, understanding the dynamics of the interaction between the agents in a process is one of the most important factors regarding its operation and design. Membrane processes for industrial wastewater management are not strangers to this topic. One such example is the concentration of compounds with high added value, such as the phenolic compounds present in olive mill wastewater (OMW). This process is a viable option, thanks to the forward osmosis (FO) process, osmotically driven by a saline stream. In this context, the transport of the solute and the solvent through the FO membranes, although essential to the process, remains problematic. This paper presents a study to predict, by means of a theoretical model, the water flux for two membranes (a cellulose triacetate flat sheet and a polyamide hollow fiber with integrated aquaporin proteins) with different characteristics using a sodium chloride solution as the draw solution (DS). The novelty of this model is the consideration of the contribution of organic compounds (in addition to the inorganic salts) to the osmotic pressure in the feed side. Moreover, the geometry of the modules and the characteristics of the membranes were also considered. The model was developed with the ability to run under different conditions, with or without tyrosol (the compound chosen as representative of OMW phenolic compounds) in the feed solution (FS), and was fitted and evaluated using experimental data. The results presented a variability in the model prediction, which was a function of both the membrane used and the FS and DS, with a greater influence of tyrosol observed on the permeate flux in the flat cellulose triacetate membrane.
