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 ...
Subsurface stormwater retention with pervious concrete pavement on UPRM campus master plan
(2018-05)
Pervious concrete pavement constitutes an efficient Best Management Practice (BMP)
stormwater management solution, since it serves to manage surface runoff quantitative and
qualitative characteristics at its earliest ...
Remediation of explosives-containing water using advanced oxidation and sorption processes
(2009)
The main objective of this work is to develop a procedure to degrade and remove explosives contained in water (ECW). Specifically, this investigation assessed the degradation and removal of TNT and DNT using advanced ...
Enhanced trichloroethylene remediation with a polymer-aided alcohol flushing
(2010)
In situ flushing for remediation of dense non-aqueous phase liquids (DNAPLs) contaminated soil and groundwater is done by the injection of a solvent solution into the contaminated zone. The system is followed by downstream ...
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 ...
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 ...
Disinfection by-products occurrence and Escherichia Coliform removal in a point-of-entry cistern purification unit
(2012)
This research aims to develop and test a Point-of-Entry Cistern Purification Unit (POE-CPU) to guarantee water quality for household purposes, with an emphasis on turbidity, E. coli removal and minimal occurrence of ...
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 ...
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 ...
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 ...
