“…Inicialmente, os estudos sobre estruvita concentravam-se em estratégias para evitar sua precipitação, devido ao entupimento de tubulações por cristais de estruvita, o que reduzia a dos sistemas de tratamento de efluentes (KATAKI et al, 2016). No entanto, atualmente, há uma série de pesquisas voltadas para a recuperação de nutrientes, como nitrogênio e fósforo (ABEL-DENEE et al, 2018;AMINI et al, 2017;CRUTCHIK et al, 2018;HERMASSI et al, 2018;WANG et al, 2016;ZIN;TIWARI;KIM, 2020), ou exclusivamente fósforo (AGRAWAL et al, 2018;CRUTCHIK et al, 2017;HUANG et al, 2017;LU et al, 2017;WANG et al, 2020;WARD et al, 2018;WU et al, 2018). Além disso, são encontrados estudos que analisam a formação da estruvita (AGRAWAL; GUEST; CUSICK, 2018) ou o desempenho dos reatores utilizados (AGUADO et al, 2019).…”

“…A major issue that the world is facing is reducing or eliminating phosphorus from water resources. Basically, a number of techniques have been used to remove phosphorus from wastewater, including 10.11113/mjfas.v19n5.3053 crystallisation, non-aqueous phase extraction, microalgae membrane, adsorption, electrocoagulation, electrochemical, sorption, membrane filtration and reverse osmosis [1][2][3][4][5][6][7][8][9][10][11]. Of these, solvent extraction is considered as an attractive option, owing to its simple operation, low cost as well as potential for phosphorus removal and recovery [12][13][14].…”

This work addresses the development of green formulation for phosphorus compound removal from aqueous solution via solvent extraction process. Several types of extractants, diluents and stripping agents were experimentally investigated and the best formulation was determined. Additionally, other parameters investigated were extractant and stripping agent concentrations. Results showed that TOMAC, a mixture of palm oil (PO) and sunflower oil (SO) as well as sodium chloride (NaCl) turned out to be the best extractant, diluent and stripping agent, respectively. Almost 100 % of 50 ppm of phosphorus were successfully extracted under optimum conditions of 0.3M TOMAC in a mixture of 50% PO + 50% SO. Fourier-transform infrared spectroscopy (FTIR) analysis confirmed the intermolecular bonding formation between phosphorus, vegetable oils and TOMAC molecules. Meanwhile, almost 96.5% of phosphorus can be recovered using 1.0M NaCl in two stages of stripping process. Stoichiometric studies showed that about one mole of TOMAC and NaCl were involved during the extraction and stripping reaction of phosphorus, respectively. It can be concluded that the solvent extraction with new green formulation containing TOMAC in interaction with vegetable oils seems to be one of the novel sustainable approaches in removing phosphorus from agricultural wastewater.

“…In general, biological phosphorus removal alone does not meet the discharge requirements of the effluent concentration below 0.5 mg/L of phosphorus and is usually accompanied by chemical phosphorus removal [6,7]. Crystallizationbased phosphorus removal is of significant interest in the field of wastewater phosphorus removal and phosphorus recovery and constitutes a reliable advanced method for treating phosphorus-containing wastewater [8][9][10]. However, the crystallization approach requires the influent to be alkaline and also requires a certain concentration of calcium ions [11].…”

As an efficient water treatment method for treating dilute solution systems, electrosorption is promising for the separation and recovery of organic compounds, wastewater treatment, and deep purification of water. Here, two types of UiO-66 samples were prepared using the solvothermal synthesis method, and the effects of different regulators on the microstructure of materials were compared using the various characterization methods. The electrochemical properties of the activated carbon and two types of materials were tested by cyclic voltammetry and AC impedance spectroscopy, and the desalination effect of the materials on phosphate was investigated. The UiO-66 material with uniform-size particles, smaller-size particles, and more surface adsorption sites exhibited better phosphate removal and adsorption capacity. It was found that the desalination process of the UiO-66 material is reversible, and the adsorbent material can be reused, which is advantageous for engineering applications.
