Use of Sawdust of Aspen Tree for the Removal of Chromium (VI) from Aqueous Solution
Adsorption capacity of Cr (VI) onto sawdust of aspen tree and activated sawdust, was investigated in a batch system by considering the effects of various parameters like contact time, initial concentration, pH , temperature, ...
Using Fuzzy Regression Approach in Prediction Municipal Solid Waste Generation: A Case Study of Mashhad
Any comprehensive plan for management of urban solid wastes requires accurate forecast of the waste level. Development of a reliable model to predict impacts of economic trends, changes in population, and environmental transformations on generation...
Mesophilic co-digestion of municipal solid waste and sewage sludge: Effect of mixing ratio, total solids, and alkaline pretreatment
A large number of biogas plants feeding with municipal solid waste (MSW) are installed throughout the world. However, researches are widely conducted with the aim of maximizing the process yield, in order to make it more comparable with fossil fuels...
Hybrid landfill gas emissions modeling and life cycle assessment for determining the appropriate period to install biogas system
Municipal solid waste landfills are known as one of the main greenhouse gas resources in the world. One solution to mitigate greenhouse gas emissions from these resources is to install biogas recovery systems. In this regard, determining...
Improving early growing stage of Festuca arundinacea Schreb. using media amendments under water stress conditions
factor, growing media amendments, was applied at nine levels of municipal solid waste -MSW-, vermicompost -5% and 10% w/w-, Stockosorb® -1% and 3% w/w- or zeolite superab sorbent -4% and 8% w/w- which were mixed with loam soil, and the loam soil was used...
Application of nut shells for chromium removal from wastewater
Adsorption capacity of Cr (VI) onto activated carbon, almond and apricot shells was investigated in a batch system by considering the effects of various parameters like contact time, initial concentration, pH, temperature, ...
Transient mass transfer modeling and simulation of polybrominated diphenyl ethers combustion in incinerators
In this paper, modeling and simulation of combustion process for polybrominated diphenyl ethers in rotary kilns has been investigated. Proper formula is found for the solid wastes which contain polybrominated diphenyl ethers and then combustion...
Growth and Reproduction of Eisenia fetida in Vermicomposting of Organic Fraction of Municipal Solid Wastes
The objective of this research is to investigate the growth and reproduction
of Eisenia fetida during vermicomposting of organic fraction
of municipal solid waste (OFMSW). Furthermore the research was intended
to assess...
Effect of adsorbents and chemical treatments on the removal of strontium from aqueous solutions
In the present investigation, three different solid wastes namely almond green hull, eggplant hull, and moss were initially treated and used as adsorbents for the adsorption of strontium ion from aqueous solutions. Adsorbent types and chemical...
