Treatment of net washing wastewater by Fenton process

by

Ozgur C. et al. View all

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...

Utilizing rice husk ash as a bio-waste material in geopolymer composites with aluminium oxide

by

Thirukumaran. T and Vivek. S et al. View all

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...

Effect of biochar on tungsten bioavailability and uptake grown in a soil with artificially tungsten contaminated

by

Wei-Jiang Chen,Ming Chen et al. View all

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

by

Zhentao Zhu et al. View all

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...
