Immobilization of Lead, Tungsten, and Phosphate by Steel Slag Fines: Metals Thresholding and Rate Studies
(American Society of Civil Engineers, 2014)This study presents an evaluation of 9.5-mm minus steel slag fines (SSF) to immobilize lead (Pb), tungsten (W), and phosphate (P as -
Treating Navy Wastewaters Using High-Shear Rotary and Tubular Membrane Systems
(American Society of Civil Engineers, 2014)Membrane filtration systems can handle varying wastewaters with simple and robust operation. However, current low permeate flux rates attributed to solids accumulation at the membrane surface limit more widespread technology ... -
Application of Data-Driven and Optimization Methods in Identification of Location and Quantity of Pollutants
(American Society of Civil Engineers, 2015)Water pollution is one of the major problems in providing and preserving water resources, so identifying the pollution source plays a critical role in regulation actions. Thus, this paper addresses the process of pollution ... -
Infectious Medical Waste Management System at the Regional Level
(American Society of Civil Engineers, 2014)The objective of this work was to do a preliminary design of a management system for infectious medical waste (IMW) at the regional level and apply it to the region of East Macedonia–Thrace (EMT) in Greece. The main ... -
Novel Adsorbent Hydrous Bismuth Oxide for the Removal of Nitrate from Aqueous Solutions
(American Society of Civil Engineers, 2015)Hydrous bismuth oxides (HBOs) have the sorptive property to remove nitrate from water. HBOs are also efficient in removing other competitive anions like bicarbonates and sulfates from water. To use HBOs as sorptive filtration ... -
Assimilative Capacity and Flow Dilution for Water Quality Protection in Rivers
(American Society of Civil Engineers, 2015)Industrial and urban development is a common cause of increased pollution. Pollutants are in many instances discharged untreated to rivers due to lack of adequate treatment facilities and high treatment cost. In many cases, ... -
Hazardous Wastes Generated in the Manufacture of High-Explosive 1,3,5-triamino-2,4,6-trinitrobenzene
(American Society of Civil Engineers, 2014)The hazardous wastes generated in the manufacture of high-explosive 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) from starting material 1,3,5-trichlorobenzene are described. The process generates three kinds of effluents: ... -
Capture Zone Comparison for Photovoltaic Microgrid-Powered Pump and Treat Remediation
(American Society of Civil Engineers, 2014)Pump and treat groundwater remediation systems typically rely on utility power to continuously pump contaminated groundwater to an above-ground treatment unit. The use of renewable energy for a pump and treat remediation ... -
Occurrence and Removal of Earthy-Musty Odorants in Two Waterworks in Kinmen Island, Taiwan
(American Society of Civil Engineers, 2014)In this study, the occurrence and treatment of two earthy-musty odorants, geosmin and 2-MIB, produced by cyanobacteria is investigated at two conventional drinking-water treatment plants (WTPs) at Kinmen Island, Taiwan. ... -
Treatment of Petrochemical Wastewater by Acid Precipitation and Carbon Adsorption
(American Society of Civil Engineers, 2014)This paper deals with the physicochemical treatment of petrochemical wastewater emanating from a purified terephthalic acid (PTA) manufacturing unit. The PTA wastewater has a very high chemical-oxygen demand ( -
PAHs Removal from Urban Storm Water Runoff by Different Filter Materials
(American Society of Civil Engineers, 2014)Urban storm water runoff is contaminated as deleterious materials wash from roadways, parking lots, and open spaces, and the subsequent discharge into surface water sources, such as lakes, can pose adverse effects on public ... -
Application of Emulsified Substrate Biobarrier to Remediate TCE-Contaminated Groundwater: Pilot-Scale Study
(American Society of Civil Engineers, 2014)Groundwater at many existing and former industrial areas and disposal sites is contaminated by halogenated organic compounds that were released into the environment. One cost-effective approach for the remediation of the ... -
