A sustainable approach for heavy metals removal from surface water by sand column amendment with bio-adsorbent of pistachio hull waste (PHW): Batch and fixed-bed column adsorption J. Water Process. Eng. (IF 6.3) Pub Date : 2024-09-05 Hoda Ganji, Mohsen Taghavijeloudar, Saeed Reza Khodashenas
In this study, pistachio hull waste (PHW) powder was added to sand column filtration systems as a natural adsorbent to increase HMs removal from contaminate river water. First, the characterization of PHW before and after Pb adsorption was determined using SEM, EDX, XRD, FTIR, BET and proximate analysis. Then, the HMs adsorption capability of PHW was investigated through batch experiments using polluted

Finding quantitative characterization strategy to elucidate perm-selectivity behavior variation of RO-TFC membranes in acidic and alkaline chlorination environments J. Water Process. Eng. (IF 6.3) Pub Date : 2024-09-05 Chaoyue Chang, Fuling Huang, Grace Vita Santoso, Qun Wang, Jian Wang, Zhaofeng Liu
RO-TFC membranes exposed to acidic and alkaline chlorination environments exhibited distinctive desalination behaviors, yet the microstructural alterations induced by chlorination lack effective means of characterization. In this study, a variety of quantitative characterization techniques were employed to analyze the separation layer of RO-TFC membranes subjected to varying pH levels and chlorination

Protein recovery from animal by-product wastewater rich in protein for application as biostimulant in agriculture J. Water Process. Eng. (IF 6.3) Pub Date : 2024-09-05 Henoc Pérez-Aguilar, Carlota Hernández-Fernández, Francisca Arán-Ais
Free amino acids-based biostimulants are increasingly used in modern agriculture for their ability to stimulate plant growth, improve crop productivity, and reduce reliance on synthetic fertilisers. This study introduces a novel and sustainable approach using enzymatic hydrolysis to recover high-value protein from animal by-product wastewater while reducing dependence on synthetic fertilisers. This

MnO2@rGO modified stainless steel mesh as cathode membrane in MFC-MBR for enhanced bioelectricity generation and membrane fouling mitigation J. Water Process. Eng. (IF 6.3) Pub Date : 2024-09-05 Huijie Zhang, Yingxuan Wu, Chongfang Zhong, Guoliang Wang, Bin Wang, Chunping Ma, Hongbin Zhang, Chao Ding, Yuping Liu, Chuncai Kong, Zhimao Yang, Tong Wang, Hao Zhu
A stainless steel mesh cathode membrane modified by MnO and rGO (MnO@rGO-SSM) was developed for a microbial fuel cell-membrane bioreactor (MFC-MBR) system. The stainless steel membrane was successfully coated with MnO and rGO through electrodeposition. The wastewater used in this experiment was synthetic wastewater simulating domestic sewage. A improvement in bioelectricity generation was achieved

Comparative phosphate sorption and recovery potential of mono and bimetallic iron‑lanthanum impregnated biochar derived via co-pyrolysis of sewage sludge and wheat straw: Highly effective phosphatic fertilizer J. Water Process. Eng. (IF 6.3) Pub Date : 2024-09-05 Iqra Irfan, Muhammad Ali Inam, Rashid Iftikhar
This research investigates the PO₄ sorption and recovery potential of mono and bimetallic iron‑lanthanum co-pyrolyzed biochar (CBC) derived from sewage sludge and wheat straw. The synthesized sorbents were described as Fe@CBC, La@CBC, and Fe-La@CBC, respectively. Owing to its reduced crystallinity and uneven pores distribution, Fe-La@CBC presented a higher PO₄ sorption potential (26.02 mg/g) than Fe@CBC

A novel strategy for preparing porous Fe/Ca-loaded biochar transformed from municipal sludge towards phosphate removal J. Water Process. Eng. (IF 6.3) Pub Date : 2024-09-05 Quanfeng Wang, Yang Xiao, Jiufang Qi, Haoxuan Wei, Jujiao Zhao, Xiaoling Lei, Demin Yang, Yuanyuan Huang, Pei Gao
The removal of phosphate from wastewater has gained much attention, and the cost-effective adsorbent with great performance is still a urgent need. In this study, a Fe/Ca-loaded biochar composite adsorbent (gBC600-4B) was obtained by simply mixing iron oxide, calcium oxide, and municipal sludge followed by co-pyrolysis. A high specific surface area (SSA) of the gBC600-4B was detected to be 160.79 m2/g

From time series to visibility algorithms: A novel approach to study the spread of SARS-CoV-2 in wastewater J. Water Process. Eng. (IF 6.3) Pub Date : 2024-09-05 A. Simone, A. Cesaro, G. Esposito
The detection of SARS-CoV-2 in faeces encouraged various studies exploring wastewater as a disease surveillance tool from a wastewater-based epidemiology (WBE) perspective. Virus concentration data in wastewater are collected and arranged in time series and generally analysed by using statistical approaches. However, for studying complex and non-linear phenomena, this procedure may not be effective

Effect of washing method and detergent type on laundry greywater characteristics J. Water Process. Eng. (IF 6.3) Pub Date : 2024-09-05 Irshad N. Shaikh, M. Mansoor Ahammed
Domestic laundry, accounting for 15 to 40 % of total water consumption, contributes significantly to household water consumption, suggesting its potential for non-potable reuse. The effect of washing method (machine vs. manual) and detergent type (liquid vs. powder) on the quantity and quality of laundry greywater was studied in the present study. The influence of washing machine, capacity and detergent
