Polymer inclusion membranes (PIM) have gained global attention in the removal of heavy metals from aqueous samples. Mercury is a toxic metal that can cause serious health effects to humans even if present in traces. Hence, its removal from water bodies and wastewaters is a necessary action. The present work, thus, aims at studying the removal of Hg2+ ions by using PIM with a new and unexplored neutral

Valorization of Plastic Waste to Generate Hydrocarbons by Hybrid Pyrolysis Environ. Eng. Sci. (IF 1.8) Pub Date : 2022-07-05 Kesari Gopi Kiran, Sheshagiri Dixit, Kalya Tulasidas Vadiraj
In the current condition, plastic has been ubiquitous, and plastic wastes generated are rising everyday. Plastic recycling and landfill are the only ways followed by the authorities in India, and due to enormous quantity of waste generation landfilling is not feasible. These plastic wastes can be converted into valuable fuel source through pyrolysis. Plastics like high-density polyethylene, low-density

Characterization of Extracellular Polymeric Substances by Microscopic Imaging Techniques in Wastewater Biotreatment: A Review Environ. Eng. Sci. (IF 1.8) Pub Date : 2022-06-07 Xiaoxiao Huang, Shuai Wang, Lu Fu, Fang Fang, Jinsong Guo
Extracellular polymeric substances (EPS) are an important part of microbial aggregates in wastewater biotreatment. EPS maintain the spatial arrangement of microbial aggregates and greatly affect the structure and properties. The production and distribution of EPS can reflect the attachment and aggregation of microorganisms. Microscopic imaging technique (MIT) can visually show the apparent morphology

Fats, Oils, and Greases Increase the Sensitivity of Anaerobic Mono- and Co-Digester Inoculum to Ammonia Toxicity Environ. Eng. Sci. (IF 1.8) Pub Date : 2022-06-07 Ashley E. Berninghaus, Tyler S. Radniecki
Interest in anaerobic co-digestion of fats, oils, and greases (FOG) has increased recently, resulting in research efforts to enhance stability of these systems and increase biogas production. Ammonia inhibition has been well-established for anaerobic digestion of municipal sludge from wastewater treatment plants. However, the inhibitory effects that occur in the presence of FOG are typically overshadowed

Occurrence and Potential Health Risks Due to Trihalomethanes and Microplastics in Bottled Water Environ. Eng. Sci. (IF 1.8) Pub Date : 2022-06-07 Naseeba Parveen, Ved Prakash Ranjan, Shamik Chowdhury, Sudha Goel
In recent years, microplastics (MPs) and trihalomethanes (THMs) in drinking water have attracted widespread concern. In this study, bottled water (BW) samples from India were evaluated for both THMs and MPs, and their health risks were assessed. Forty-four samples of BW of 18 brands were tested and THMs were detected in all 44 BW samples tested. At least 1 THM was quantified in 20 BW samples, and all

Treating Mariculture Wastewater Using Electrocoagulation-Microscreen Drum Filter Technology: Electrode Passivation and Influencing Factors Environ. Eng. Sci. (IF 1.8) Pub Date : 2022-06-07 Jianping Xu, Tianlong Qiu, Fudi Chen, Li Zhou, Ye Li, Jianming Sun, Yishuai Du
This study aimed to improve the performance of the continuous flow electrocoagulation (EC)-microscreen drum filter (MDF) system in treating mariculture wastewater by investigating the passivation behavior of electrodes under different factors. Using response surface methodology, the effects of salinity (10–30‰), current density (15–75 A/m2), inlet flow (100–300 L/h), and electrode's continuous working

Landfill Impervious Layer Damage in Operation Based on Machine Vision Environ. Eng. Sci. (IF 1.8) Pub Date : 2022-06-07 Yayu Chen, Jianlong Li, Shijun Bi, Zheng Ma
Aiming at the problem that the leakage area of high-density polyethylene membrane cannot be longitudinally located and contour identified under landfill conditions. First, according to the vibration difference characteristics of the landfill medium layer, a cross-correlation processing model is proposed using the calibration signal and the actual collected working signal. Combined with the complex

Assessment of Nitrous Oxide and Carbon Dioxide Emissions and the Carbon Footprint in an Aerobic Granular Sludge Reactor Treating Domestic Wastewater Environ. Eng. Sci. (IF 1.8) Pub Date : 2022-06-07 Gilberto Caye Daudt, Bruna Scandolara Magnus, Cássio Moraes Schambeck, Nelson Libardi, Rejane Helena Ribeiro da Costa
The assessment of nitrous oxide (N2O) and carbon dioxide (CO2) emissions from wastewater treatment processes using aerobic granular biomass is still scarce and most of them deal with synthetic wastewater in well-controlled conditions. Also, the greenhouse gases footprint from aerobic granular process has been poorly described despite a strong impact on climate change. This work quantified and analyzed

Anaerobic Digestion of Kraft Pulp Mill Foul Condensate Under Thermophilic and Mesophilic Conditions Environ. Eng. Sci. (IF 1.8) Pub Date : 2022-06-07 Alexander C. Hayes, Camilla Nesbø, Elizabeth A. Edwards, Earl Jenson
Foul condensate produced during the chemical recovery step of the kraft pulping process is a methanol-rich wastewater stream commonly treated through a steam-stripping process to extract volatile components before their combustion. Applying anaerobic digestion to treat this wastewater stream presents an opportunity to recover the inherent renewable bioenergy without the associated steam utilization
