“…However, adsorption via granular activated carbon is known as to be used for removal of heavy metal ions from wastewaters. When well optimized, GAC can account for 99.02% and 79.05% of iron and manganese removal efficiencies, respectively (Goher et al 2015). Therefore, this adsorption process would change the metal composition of the wastewater.…”

The potential of a wastewater treatment and biomass production process with the green microalgae Neochloris oleoabundans in a 45-L tubular photobioreactor was tested. In a stable and reliable alga-based process, wastewaters should undergo pre-treatment to remove colored substances. Our data show that further optimization steps may be required, such as adjustment of the N:P ratio and addition of essential metals. As a final result, parameters were established for a continuous-mode photobioreactor run with optimized wastewater for five times the hydraulic retention time (157 h) at the dry biomass concentration of 0.47 ± 0.03 g L −1 . During that period, 75% and 99.6% removal efficiencies for NH 4 + and PO 4 3− , respectively, were achieved.

“…Among these technologies, adsorption is preferred because it is more economical and readily available . A variety of adsorbents have been used to remove manganese from wastewater through this process: activated carbon, fly ash, lignite, natural zeolite, synthetic zeolite, clinoptilolite, various polymers, surfactant modified alumina, sugarcane bagasse, sugar beet pulp, bean pods waste, coffee beans, soybean hulls, sunflower stalks, rice husk, coconut shells, waste tea leaves, thermally decomposed leaf, bark of the trees and cotton stalks …”

BACKGROUND: In the circular economy context, the present article proposes a green technical solution by manganese ions adsorption on oak wood ash and the reuse of the new waste generated by the adsorption process as soil amendment. RESULTS:The influence of the main process variables: pH, adsorbent dose and contact time was investigated for optimal manganese ions adsorption. The highest adsorption efficiency of the wood ash (more than 98%) was recorded at pH 6, adsorbent dose of 10 g L −1 and contact time 15 min. The ion adsorption process is best described by Langmuir isotherm and pseudo second-order kinetic model. Maximum adsorption capacity, 54.94 mg g −1 , is better than other adsorbent materials previously used for manganese adsorption. The exhausted wood ash, resulted after the manganese adsorption was used as soil amendment for barley crop, Hordeum vulgare L. The beneficial effect upon the studied plants was highlighted using the specific parameters: germination percent (up to 10% higher), plant average length (higher by 14-35%), biomass (up to 200%) and relative growth rate (higher by 6-12%) compared to those obtained for the control sample.CONCLUSION: These results show that all the wastes involved have been used successfully and support the proposed ecofriendly technical solution for some industrial wastes management.

“…In past few years, various methods, viz. coagulation, reverse osmosis, ion exchange, and bio‐sorption, have been developed for the extraction of Al(III) from wastewater (Gabelich et al, ; Ghazy, Samra, Mahdy, & El‐Morsy, ; Goher et al, ; Mahdavi et al, ; Okuda et al, ; Petrie, Fleming, McKinnon, Winney, & Cowie, ). Besides, there are several techniques such as ion exchange, adsorption, coagulation, and electrodialysis have been identified to be successful in the removal of excess fluoride from contaminated water (Agarwal, Dubey, & Gupta, ; Nasr, Charcosset, Amar, & Walha, ; Sharma et al, ; Sujitha & Ravindhranath, ).…”

The present work proposes the synthesis of robust biochar from Gracilaria Rhodophyta red weeds for sequential removal of Al(III) and fluoride from wastewater. The sorption experiments have been modeled by preliminary optimization of operational parameters using 2 4 factorial statistical modeling. The model has estimated an optimum sequential synergetic removal of 44.5 mg/g of Al(III) and 2.1 mg/g of fluoride onto the biochar. FESEM, BET, XRD, EDX, and FTIR established the potentiality of biochar toward synergetic sorption of Al(III) and fluoride. The thermodynamic analysis projected that the adsorption is physisorption in nature. The adsorption of Al(III) and fluoride follows the Langmuir and Freundlich isotherm models, respectively, and the kinetic analysis established the pseudo-second-order deposition of Al(III) and fluoride ions. The synthesized adsorbent is regenerative enough and could achieve synergetic removal of Al(III) and fluoride ions from industrial-and groundwater-contaminated water bodies. © 2019 Water Environment Federation • Practitioner points• Biochar from seaweeds is explored in the sequential removal of Al(III) and F − ions. • Statistical model is developed for % adsorption and tested for reliability by ANOVA. • GRBC sorbed 44.5 and 2.1 mg/g of Al(III) and F − ions, respectively, at optimum levels. • FESEM, EDX, XRD, and FTIR characterization confirm the potentiality of the GRBC. • GRBC sorbed ⃞90% of Al(III) and F − ions from wastewater and is regenerative.
