Determination of Fungi Species Variety in Thermal Phases of Compost Production and Related Operational Parameters
(American Society of Civil Engineers, 2018)Compost is a self-heating process in which organic matters are stabilized by microorganisms. Fungi are one of the suitable indicators of compost stabilization, but many parameters affect their growth. The aim of this paper ... -
Turbidity of Stormwater Runoff from Highway Construction Sites
(American Society of Civil Engineers, 2018)The US Environmental Protection Agency (EPA) proposed a new “Effluent Limitations Guidelines” for construction site runoff management in 29, which required that stormwater effluents be sampled and that the daily average ... -
Application of Modified Zeolite and Modified Peat in Removing Salinity Ions from Irrigation Saline Waters
(American Society of Civil Engineers, 2018)In the present study, adsorbents of zeolite and peat were modified in two ways, one using cationic surfactant of hexadecyltrimethylammonium bromide (HDTMABr) and sodium hydroxide (NaOH), and the other using hydrochloric ... -
High Frequency Sonochemical Degradation of Benzophenone-3 in Water
(American Society of Civil Engineers, 2018)Degradation by high frequency ultrasound (US) of the endocrine disruptor, benzophenone-3 (BP-3) is a promising treatment process as it does not need additives and does not generate waste. In this paper the variables affecting ... -
UV-Irradiated Strain of Acidithiobacillus ferrooxidans Improved Copper Bioleaching in Chalcopyrite
(American Society of Civil Engineers, 2018)Bioleaching is a process that uses microorganisms to perform dissolution of sulfide minerals. Actually, most copper is found as chalcopyrite ore, which is the most abundant form of copper sulfide, but it is recalcitrant ... -
Detecting the End of Nitrification in Small and Decentralized Wastewater Treatment Systems Using Low-Resource Real-Time Control Methods
(American Society of Civil Engineers, 2018)There is increasing demand on operators of small-scale wastewater treatment plants (WWTPs) to improve biological nutrient removal and energy efficiency while being subject to unique challenges, including reduced resources. ... -
Sugarcane Bagasse as a Microbial Host Media for the Passive Treatment of Acid Mine Drainage
(American Society of Civil Engineers, 2018)Anoxic microcosms and flow-through experiments were used to evaluate the ability of sugarcane bagasse to support biogenic sulfide production that can mitigate pH and immobilize heavy metals commonly found in acid mine ... -
Prediction of Longevities of ZVI and Pervious Concrete Reactive Barriers Using the Transport Simulation Model
(American Society of Civil Engineers, 2018)This investigation involved a column study and model simulation to evaluate longevity of zero-valent ion (ZVI) and pervious concrete (PERVC) reactive barriers for treatment of acid mine drainage (AMD). Each of the reactive ... -
Visible Light Photocatalytic Ozonation of Oxalic Acid by MnOx-g-C3N4 Composite
(American Society of Civil Engineers, 2018)MnOx-g-C3N4 composite is prepared and characterized by X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), X-ray fluorescence (XRF), ultraviolet–visible (UV-vis) spectroscopy, and surface area analysis. The ... -
Effect of Aging and Wet-Dry Cycles on the Elimination of the Bioavailable Fractions of Cu and Zn in Contaminated Soils by Zero Valent Iron and Magnetic Separation Technique
(American Society of Civil Engineers, 2018)Anthropogenic activities are continually transforming the Earth’s surface and resulting in significant disturbances of ecosystem services including those provided by soil resources. However, advances in chemical, biological, ... -
Removal of Hexavalent Chromium from Aqueous Solutions Using Biopolymers
(American Society of Civil Engineers, 2018)Two biopolymers were prepared by reaction of chestnut and quebracho tannins with gelatin extracted from untanned hide wastes. Obtained biopolymers were evaluated as adsorbents for removing Cr(VI) from water using the batch ... -
Lumped versus Distributed Hydrological Modeling of the Jacaré-Guaçu Basin, Brazil
(American Society of Civil Engineers, 2018)The study aims to understand when the effort required to run a distributed and detailed water balance model leads to effective better results, when compared with a lumped, data-parsimonious, and easier-to-apply hydrological ... -
Graphene Oxide–Supported Cobalt Phthalocyanine as Heterogeneous Catalyst to Activate Peroxymonosulfate for Efficient Degradation of Norfloxacin Antibiotics
(American Society of Civil Engineers, 2018)Developing highly potent and environmentally friendly catalysts to activate peroxymonosulfate (PMS) to generate reactive species has received considerable and increasing attention in the field of antibiotics elimination. ... -
Impact of Climate Change on Water Resources in India
(American Society of Civil Engineers, 2018)Direct and indirect effects of climate change will have an adverse impact on water resources, human systems, regional agriculture, and food security. India, with a population of more than 1.2 billion, has experienced ... -
Organic Matter Removal in a Membrane-Aerated Biofilm Reactor
(American Society of Civil Engineers, 2018)The control of biofilm thickness is one of the challenges of using the membrane aerated biofilm reactor (MABR) because high thicknesses block oxygen and substrates transferred to the biofilm layers, resulting in MABR ... -
