A solid-phase extractant based on microemulsion modified date pits for toxic pollutants
(2013 , Article)Application of microemulsion modified raw date pits as an inexpensive solid extractant for removing methylene blue (MB), copper ion (Cu2+) and cadmium ion (Cd2+) has been presented. The results summarised herein are also ... -
An analytic network process condition assessment model for sewer pipelines
( Civil-Comp Press , 2015 , Conference)As sewer pipelines age, the need for their upgrading, maintaining, and repairing arises. Simultaneously, inadequate sewer pipelines might lead to catastrophic failures. Thus, decision makers must have a detailed knowledge ... -
An economic loss model for failure of sewer pipelines
( Taylor and Francis Ltd. , 2018 , Article)Estimating the costs of failure for sewer pipelines is usually accompanied with uncertainties because of the difficulty in capturing the relationship between the physical and economical characteristics of failed pipelines. ... -
Automated defect detection tool for closed circuit television (cctv) inspected sewer pipelines
( Elsevier B.V. , 2018 , Article)In sewer networks, the economic effects and costs that result from a pipeline failure are rising sharply. As a result, there is huge demand for inspection and rehabilitation of sewer pipelines. In addition to being inaccurate, ... -
Characteristics of olive mill solid residue and its application in remediation of Pb2+, Cu2+ and Ni2+ from aqueous solution: Mechanistic study
( Elsevier , 2014 , Article)This study investigated the use of untreated olive mill solid residues (OMSR) as a solid extractant for Pb2+, Cu2+ and Ni2+ ions from aqueous solution. It was shown that the solution initial pH value affected the metal ... -
Condition assessment model for sewer pipelines using fuzzy-based evidential reasoning
( Taylor and Francis Ltd. , 2018 , Article)A condition assessment model for gravity and pressurised sewer pipelines using Fuzzy Set Theory (FST), and Evidential Reasoning (ER) with the aid of Fuzzy Analytical Network Process (FANP) integrated with Monte-Carlo ... -
Defect based risk assessment model for prioritizing inspection of sewer pipelines
( American Society of Civil Engineers (ASCE) , 2018 , Conference)In presence of financial constraints and dire need for inspecting deteriorated sewer pipelines, inspection prioritization tools are required. This paper presents a defect based risk assessment model for prioritizing ... -
Defect-based ArcGIS tool for prioritizing inspection of sewer pipelines
( American Society of Civil Engineers (ASCE) , 2018 , Article)This paper presents a defect-based model for assessing risk of failure for sewer pipelines. The proposed model deploys a Sugeno fuzzy inference system to create a risk index from which inspection and replacement activities ... -
Determining relative weights of sewer pipelines' components and defects
( American Society of Civil Engineers (ASCE) , 2018 , Article)Condition assessment models for sewer network components can be considered a tool for key personnel to make informed decisions regarding the required interventions on the basis of the current conditions of these components. ... -
Multi-Objective Optimization Model for Inspection Scheduling of Sewer Pipelines
( American Society of Civil Engineers (ASCE) , 2019 , Article)Inspection activities play an important role in the operation and maintenance (O&M) strategy in municipalities. Efficient O&M strategies can help in making informed decisions based on the actual condition of pipelines ... -
Organically modified nanoclay filled thin-film nanocomposite membranes for reverse osmosis application
( MDPI AG , 2019 , Article)This study validates, for the first time, the effectiveness of two nanoclays, that is, cloisite (CS)-15A and montmorillonite (MNT) at the polyamide (PA) active layer in the reverse osmosis (RO) membrane. Cloisite-15A is ... -
Uptake of Reactive Black 5 by pumice and walnut activated carbon: Chemistry and adsorption mechanisms
( Korean Society of Industrial Engineering Chemistry , 2014 , Article)The potential of using pumice and walnut wood activated carbon as low-cost adsorbents for the removal of the diazo dye Reactive Black 5 (RB5) from aqueous solutions was investigated. The Langmuir isotherm fit to the data ...
