Treatment of net washing wastewater by Fenton process
Advanced Oxidation Processes
The discharge of wastewater from net washing is one of the most significant problems in the marine ecosystem because of its high organic and saline content. Sea water quality is deteriorated every day due to the high amount of organic matter produced in the aquaculture sector. The aim of this study...
Drivers of nocturnal interactions between ground-level ozone and nitrogen dioxide
Air Quality
This study analyses nighttime (7 p.m. to 6 a.m.) light pollution effects on ground-level ozone production in urban and sub-urban sites in Malaysia. In the absence of solar radiation, no photochemical reaction will occur during nighttime, resulting in zero readings of ground-level ozone (O3). O3 and...
Adsorption of Co(II) ions using indigenous tamarind seed biochar: batch adsorption and modeling studies
Water treatment
With an estimated volume of 162 thousand metric tonnes in 2020, India is the world's largest producer of tamarind. The country is home to a number of tamarind species, and production is spread out across the country. Farmers and agro-industries continue to encounter numerous challenges in the...
Treatment surface water using a novel pumpkin seed-based natural bio-coagulant: optimization by CCD and toxicity evaluation
Water and Wastewater Treatment
This goal of this study was to evaluate the effectiveness of a new coagulant extract from pumpkin seeds (PSC) for removing turbidity and organic compounds from different natural surface waters. Two design experiment methods, namely central composite design (CCD) and response surface methodology (RSM...
Experimental Investigation on Carbonation due to Climate Change Impacts
Climate change mitigation and adaptation
Various investigations have been carried out to evaluate the infrastructure’s augmented vulnerability owing to concrete carbonation persuaded by the changes in the environment during recent years. Due to global warming and its effect, carbon dioxide emission levels in the atmosphere get increased...
Utilizing rice husk ash as a bio-waste material in geopolymer composites with aluminium oxide
Biowaste
Permanent damages and spalling occur in conventional concrete due to high temperatures. Also concrete loses its compressive strength amounting to about 50 to 75% of the original strength as reported in most of the research works. As opting for high grade of concrete leads to higher costs and emits...
Utilizing Recycled Nanomaterials as a Partial Replacement for Cement to Create High-Performance Concrete
Solid Waste Management
The world is witnessing a boom-in construction industry due to urbanization which leads to over-exploitation of primary resource to match the demands and also increase the land pollution. The advent of nano engineering technology has a significant impact on cementitious materials, particularly...
Effect of biochar on tungsten bioavailability and uptake grown in a soil with artificially tungsten contaminated
Environmental Toxicology and Biogeochemistry of Ecosystems
Tungsten (W) is an emerging contaminant because of its potential toxicity to humans, and biochar (BC) is widely used for soil heavy metal remediation. However, W-biochar-plant interactions remain unknown. The objective of the study was to evaluate the effect of rice-husk BC on W uptake by lettuce...
Research on the comprehensive evaluation of collaborative governance effect of environmental pollution in the Yangtze River Delta urban agglomeration based on low-carbon constraints
Environmental Management and Policies
This paper selects a total of 24 evaluation indicators, including the low carbon constraint, the driving force, the pressure and the status of collaborative governance, to build an evaluation index system. On the basis of low carbon constraints, a spatial niche fitness model was constructed by using...
Highly efficient Cr(VI) removal by cationic covalent organic framework
Water treatment
Developing an efficient sorbent for removing the highly toxic Cr(VI) is very important, which tackles the threat of Cr(VI) pollution to ecological environment and human health. Herein, a cationic covalent organic framework bearing cationic guanidine (named TATGCl) was synthesized from...
