“…adsorption process of RBBR by CHT-GLA/ZnO/Fe3O4 is more in line with the Freundlich and Temkin models, indicating the heterogeneous character of the RBBR physical and chemical adsorption onto CHT-GLA/ZnO/Fe3O4 surface[51]. The qmax of RBBR on CHT-GLA/ZnO/Fe3O4-25 was found as 176.6 mg/g at 60 o C. Table7summarizes the comparison the qmax of the CHT-GLA/ZnO/Fe3O4-25 with other adsorbents reported in previous works toward RBBR.…”

A magnetic Schiff's base chitosan-glutaraldehyde/Fe3O4 composite (CHT-GLA/ZnO/Fe3O4) was developed by incorporating zinc oxide (ZnO) nanoparticles into its structure to prepare an efficient adsorbent for the removal of remazol brilliant blue R (RBBR) dye. The CHT-GLA/ZnO/Fe3O4 was characterized by the following methods: CHN, BET, FTIR, XRD, SEM-EDX, pHpzc, and potentiometric titrations. Box-Behnken design based on response surface methodology was used to optimize the effects of the A: ZnO nanoparticles loading (0-50%), B: dose (0.02-0.1 g), C: pH (4-10), D: temperature (30-60 °C), and time E: (10-60 min) on the synthesis of the magnetic adsorbent and the RBBR dye adsorption. The experimental data of kinetics followed the pseudo-second order model, while isotherms showed better fit to Freundlich and Temkin models. The maximum adsorption capacity of the target nanocomposite (CHT-GLA/Fe3O4 containing 25% ZnO or CHT-GLA/ZnO/Fe3O4-25) was reached of 176.6 mg/g at 60 °C. The adsorption mechanism of RBBR onto CHT-GLA/ZnO/Fe3O4 nanocomposite can be attributed to multi-interactions including electrostatic attractions, hydrogen bonding, Yoshida Hbonding, and n-π interactions. This study offers a promising hybrid nanobiomaterial adsorbent in environmental nanotechnology to separate and remove the contaminants such as organic dyes from wastewater.

“…Water demands have made the processing of wastewater flows a lucrative and readily available source of crude water. The recycled water is initially disinfected and filtered before discharge to the groundwater supply (Rizzi et al 2020 ). Several biophysical impacts are associated with recycled water for different uses (Fernández et al 2020 ).…”

Environmental rethinking of wastewater drains to manage environmental pollution and alleviate water scarcity

2021

The conservation of water resources in developed countries has become an increasing concern. In integrated water resource management, water quality indicators are critical. The low groundwater quality quantitates mainly attributed to the absence of protection systems for polluted streams that collect and recycle the untreated wastewater. Egypt has a limited river network; thus, the supply of water resources remains inadequate to satisfy domestic demand. In this regard, high-quality groundwater is one of the main strategies for saving water supplies with water shortage problems. This paper investigates the critical issues of groundwater protection and environmental management of polluted streams, leading to overcoming water demand-about 18 × 10 3 km of polluted open streams with a discharge of 9.70 billion Cubic Metter (BCM). We have proposed proposals and policies for the safe use of groundwater and reuse of wastewater recycling for agriculture and other purposes. This study was carried out using the numerical model MODFLOW and MT3DMS—(Mass Transport 3-Dimension Multi-Species) to assess the Wastewater Treated Plant's (WWTP) best location and the critical path for using different lining materials of polluted streams to avoid groundwater contamination. The three contaminants are BOD, COD, and TDS. Five scenarios were applied for mitigating the impact of polluted water: (1) abstraction forcing, (2) installing the WWTP at the outlet of the main basin drain with and without a lining of main and sub-basin streams (base case), (3) lining of main and sub-main streams, (4) installing WWTP at the outlet of the sub-basin streams, and (5) lining of the sub-basin and installing WWTP at the outlet of the sub-basin. The results showed that the best location of WWTP in polluted streams is developed at the outlets of sub-basin with the treatment of main basin water and the lining of sub-basins streams. The contamination was reduced by 76.07, 76.38, and 75.67% for BOD, COD, and TDS, respectively, using Cascade Aeration Biofilter or Trickling Filter, Enhancing Solar water Disinfection [(CABFESD)/(CATFESD)] and High-Density Polyethylene lining. This method is highly effective and safe for groundwater and surface water environmental protection. This study could be managing the water poverty for polluted streams and groundwater in the Global South and satisfy the environmental issues to improve water quality and reduce the treatment and health cost in these regions.

In this paper, a 3D nitrogen-doped carbon network with excellent adsorption properties was prepared for bisphenol S (BPS) removal from water. An optimized sample B-T700-N3 with high Langmuir specific surface area as well as plentiful heteroatoms was screened out. Benefiting from the synergistic effect of conjugation and hydrogen bonding between the adsorbent and bisphenol S, B-T700-N3 demonstrated superior adsorption performance. The maximum adsorption amount (q max,e ) of the B-T700-N3 at equilibrium was determined to be up to 91 mg/g, which was comparable or even higher than that of the state-of-the-art reported adsorbents. Experimental results illustrated that this adsorbent could also effectively remove other bisphenols (BPA, BPAF) from water. Overall, this novel adsorbent demonstrated a competitive performance for bisphenols removal in aqueous solution and can be a highly interesting candidate for industrial applications.
