The photocatalytic process can be used for water and wastewater disinfection. The aim of this study was to remove coliforms and faecal coliforms from real hospital...

The microbial consortia incorporated in bio concrete should have traits such as high alkali resistance and the ability to form endospores to overcome the mechanical and chemical stresses produced during concrete preparation. The primary intent of our work is to segregate and identify the calcium...

COVID-19 pandemic is a major worldwide health disaster firstly reported in December 2019. The Food and Drug Administration (FDA) has offered the public hope of halting it, authorizing vaccinations for emergency use with more than 85% efficacy against serious acute respiratory syndrome (SARS-CoV-2)...

The purpose is to analyze the economic development and management mechanism of rural enterprises, and explore the role of ecological environment protection mechanism in the economic development of rural enterprises. First, the related theories are analyzed and expounded; then, the participants of...

The wastes are in many forms consist of organic materials like human, medical, food, plastics, construction waste etc. many researchers are focused on the waste management to gives more importance to the environment. The bio degradable waste was used in this research with naturals fibers. The need...

Expansive soils pose a danger to the foundations of engineering structures due to their poor engineering properties. These soils are usually treated using mechanical techniques, and chemical stabilizers. However, the production of these chemicals is not friendly to the environment, thus a need to...

The Yellow River Basin is an important economic zone in China and an important base for energy, chemical, raw materials and basic industries. However, the sloppy development pattern of "high consumption and high pollution" in nine provinces along the Yellow River Basin has become an important...

Excessive use of fossil fuels results in the rapid depletion of non-renewable fossil energy resources, a rise in fuel cost, and an uncontrolled emission of greenhouse gases which causes a severe threat to the environment. Bio-fuels are being scrutinized as substitutes for current high-pollutant...

BTEX, also known as benzene, toluene, ethyl benzene, and xylene, is a common gasoline oxygenate. The contamination of groundwater and surface water with BTEX and its primary breakdown product has drawn a lot of attention. However, surface-modified zeolite's sorption mechanisms and affinity for BTEX...

The pollution and toxicological effects of microplastics in soil have gradually attracted widespread attention, but studies on the ecological effects of microplastics on soil microorganisms and their mechanisms are still very scarce. To explore the physiological response of ectomycorrhizal fungi...

The locally available tamarind fruit shells (TFS) pre-treated with 1N H3PO4 was used to remove the hexavalent chromium (Cr6+) from aqueous phase. The investigation was done by using continuously mixed batch reactor (CMBR) under room temperature. Few preliminary investigations was undertaken to...

The unique high-altitude environmental factors in the Linzhi region of Tibet have not been fully investigated in terms of their impact on the microbial mechanisms of water ecology, for which we explored the response of activated sludge microorganisms to different hydraulic retention times (HRT)...

Water treatment ecosystem provides important habitats for various bacterial communities, but the response mechanism of this ecosystem under ultraviolet rays is not yet clear. For this reason, 16S rRNA gene sequencing is used to study the bacterial community structure and metabolic pathways under...

Batch adsorption studies of heavy metals were carried out using activated charcoal groundnut shell powder as an adsorbent material.
