“…Summing up, the addition of Al 2 O 3 MPs or NPs at the appropriate concentrations improves the efficiency of separation processes in the wastewater treatment systems and facilitates the sludge management. The presence of additional contamination, i.e., mineral particles, in the sludge (particularly in the excess sludge removed from the system) Negligible effect or no deterioration of the removal of organic compounds expressed as COD from wastewater (this work; Chen et al 2012;Wang et al 2012;and Qiu et al 2016) Decrease in nitrogen removal from wastewater (Chen et al 2012;Cervantes-Avilés and Cuevas-Rodríguez 2017;and Wang et al 2016) No effect or enhancement of phosphorus removal from wastewater (Cervantes-Avilés and Cuevas-Rodríguez 2017; Xiao et al 2017) Decrease in the activity of activated sludge microorganisms (Cervantes-Avilés et al 2017;Wang et al 2016)…”

“…Generally, the degrees of nitrogen and phosphorus removal decreased with the increase in NPs concentration (Chen et al 2012;Wang et al 2016;Li et al 2017). Xiao et al (2017) proposed the application of the magnetic mineral particles to remove and recover phosphorus from the secondary effluent of the wastewater treatment plant.…”

“…Regarding the fate of NPs in the conventional activated sludge systems, it was found that nanoparticles usually adsorbed onto activated sludge flocs and then they entered the interior of the microbial cells (Chen et al 2012;Qiu et al 2016;Cervantes-Avilés and Cuevas-Rodríguez 2017;Wang et al 2016;Xiao et al 2017). In this context, the question raised is whether the presence of nanomaterials in wastewater positively or negatively influenced the flocs morphology and settling properties.…”

Nanomaterials have been usually perceived as a potential contamination of wastewater and thus tested in this context. On the contrary to this approach, here the possibility of the application of mineral microparticles or nanoparticles to improve the operation of activated sludge systems was studied for the first time. This work was aimed at checking the influence of aluminum oxide micro-and nanoparticles on morphology and settling properties of activated sludge. It was found that aluminum oxide micro-and nanoparticles changed the morphology of activated sludge flocs making them more circular. Moreover, the addition of aluminum oxide microparticles at the concentration up to 0.5 g l −1 or aluminum oxide nanoparticles at the concentration up to 0.25 g l −1 to activated sludge system caused the increase in flocs size. The changes in flocs morphology induced by aluminum oxide micro-or nanoparticles improved the separation processes in wastewater treatment systems and simultaneously did not deteriorate the efficiency of organic pollutants removal. It indicates the possibility to use aluminum oxide micro-or nanoparticles at the appropriate concentrations in wastewater treatment plants as a new solution to struggle against the bulking events.

“…The methods of removal and recovery of phosphorus used for wastewater are not suitable for agricultural drainage water, because the phosphorus loadings are lower and the water is not collected in a central treatment facility. An alternative to the methods described above is the sorption of phosphorus onto diverse materials, including bauxite (Altundogan & Tumen, 2001) and magnetite microparticles (Drenkova-Tuhtan et al, 2017;Xiao, Liu, Zhang, & Zheng, 2017). Adsorbent magnetic particles have also been successfully tested over numerous regeneration cycles for the removal of nonorthophosphate species, for example, dissolved organophosphonates, which can also pose a risk of eutrophication once released into the environment (Rott et al, 2018).…”

Phosphorus released in lakes due to agricultural water runoff causes eutrophication, deteriorating water quality and harming ecosystems. Two adsorbents were studied for the removal of phosphate from water: plaster of Paris powder and hydrogel beads produced using alginate, carboxymethylcellulose, and aluminum. The reaction kinetics, adsorption capacity, and ability to desorb were compared. Sorption of phosphate with either plaster of Paris or hydrogel beads was well described by the Langmuir model. In deionized water, hydrogel beads had a maximum sorption capacity of 90.5 mg PO43- /g dry bead with an equilibration time of approximately 24 hr. Monovalent anions (e.g., chloride) did not affect phosphorus sorption onto hydrogel beads, whereas divalent anions (e.g., sulfate) hindered sorption. In deionized water, plaster of Paris (POP) powder has a maximum capacity of 1.52 mg PO43- /g with an equilibrium time of less than 10 min. Sorbents can potentially be reused following phosphate desorption, and desorbed phosphate may be reused as fertilizer. At pH = 9.5, hydrogel beads desorbed up to 60% of the original amount of phosphate sorbed and lower amounts at lower pH. At pH = 2, POP powder desorbed only 35% of the initial phosphate sorbed, and desorption decreased with increasing pH. Practitioner points The maximum sorption capacity of plaster of Paris is 1.52 mg PO43- /g. The maximum sorption capacity of hydrogel beads is 90.5 mg PO43- /g. Monovalent anions do not affect phosphorus sorption, and divalent anions hinder it by ≈36%. Sorption is well described by Langmuir isotherms (R2 > 0.98). Hydrogel beads desorb 60% of phosphorus at pH = 9, possibly allowing phosphorus reuse.

“…[1,2]. The secondary effluents from a typical sewage treatment plant may contain 1.0-2.0 mg/L Phosphorus in an anaerobic-anoxic-oxic (A 2 /O) process [3], which contributes to eutrophication in the receiving water bodies [4]. Phosphorus in the secondary effluents is mostly present as phosphate.…”

Phosphate Removal from Secondary Effluents Using Coal Gangue Loaded with Zirconium Oxide

et al. 2019

Phosphorus from secondary effluents and coal gangue from coal mining have caused serious environmental problems. The feasibility of phosphate removal from secondary effluents using calcinated coal gangue loaded with zirconium oxide (CCG-Zr) was explored. Major influencing factors like the calcinated temperature, CCG-Zr ratio, adsorbent dose, time and solution pH, etc. were investigated. Newly developed CCG-Zr accomplished a significantly higher phosphate removal for phosphate (93%) compared with CCG (35%) at a calcinated temperature of 600 °C and CCG-Zr mass ratio of 1:1. For CCG-Zr the maximum phosphate removal rate (93%) was noted at an initial phosphate concentration of 2 mg/L within 20 min. The CCG-Zr displayed a higher phosphate removal rate (85–98%) over a wide range of solution pH (2.5~8.5). The adsorption isotherms fitted better to the Freundlich (R2 = 0.975) than the Langmuir model (R2 = 0.967). The maximum phosphate adsorption capacity of the CCG-Zr was 8.55 mg/g. These results suggested that the CCG-Zr could potentially be applied for the phosphate removal from secondary effluents.
