Water quality assessment with aquatic non-structural blocks made of coal ash aggregates mortars
(2012)
A handful of biochemical processes occur in aquatic environments. One of the problems that are mostly encountered in such environments is caused by excess nutrient input and subsequent algal bloom. A series of studies were ...
Biodeterioration of PVC plastics, biochemical fate of DEHP, and bioreactor landfills for DEHP-containing leachate management
(2014-12)
Di-(2-ethylhexyl) phthalate (DEHP), a widely used plasticizer in the manufacture of polymeric materials such as polyvinyl chloride, was studied in order to understand its fate and transport in complex environments such as ...
Performance of landfills with coal combustion byproducts aggregates as an alternative reactive daily cover
(2012-05)
A landfill is an engineered facility for the disposal of wastes. It is designed and operated to minimize public health and environmental impacts. However, land availability is the limiting factor for the operation and ...
Water quality performance of pervious concrete pavements
(2016-07)
Water is one of the most important resources for human needs and, in some countries, the lack of potable and drinking water is a serious issue. For this reason, new infrastructure that increases water conservation and ...
Sand filtration and chlorination for removal and inactivation of Bacillus subtilis
(2015)
Sustainable water treatment and technology need to be implemented for safe-drinking water. In Puerto Rico, some rural communities do not rely on the central systems operated by the water authority but have their own small ...
Optimization of pervious concrete incorporating coal fly ash, iron-oxide nanoparticles and water reducing admixtures and its application for the removal of nutrients and fecal coliforms
(2015-05)
Physicomechanical characteristics and durability of the cement pastes containing fly ash (FA) and iron-oxide nanoparticles (NI) showed that workability was reduced with the FA addition, although it was counterbalanced when ...
Statistical optimization of pervious concrete pavement containing fly ash and engineered iron oxide nanoparticles for runoff quality and quantity controls
(2014)
Portland cement pervious concrete (PCPC) usage has increased due to its potential to reduce storm water runoff and related pollution. Partial Portland cement substitution by fly ash (FA) in concrete production has the ...
Impact assessment of the presence of engineered iron oxide nanoparticles on wastewater effluent disinfection
(2014)
A previous study indicated that ~8.7% wt. Fe of the initially dosed engineered iron oxide nanoparticles coated with surfactants (ENPFe-Surf), as contaminants, was present in the effluent from the lab-scale sequencing batch ...
Treatment train with tire crumb rubber and cyperus haspan: a new approach for remediation of explosives-containing water
(2014)
The objective of this work was to study the adsorption capacity of TNT and DNT by the use of tire crumb rubber (TCR) and the phytoremediation capacity of a native plant known as dwarf papyrus. Several batch and continuous-flow ...
Effect of engineering iron oxide nanoparticles on effluent water quality from biological wastewater treatment
(2013)
The production, use, and disposal of products containing nanoparticles may lead to their appearance in air, water, and soil, and subsequently in the human body. Because there is no existing regulation, large amounts of ...
