(No paper) Pump-and-treat is a common technique for the remediation of contaminated aquifers. However, slow kinetic mass transfer at sites contaminated with organic compounds may reduce the efficiency of the pump-and-treat remediation. Although continuous pumping tends at first to remove high concentrations from an aquifer, it soon removes much lower concentrations due to slow mass transfer from immobile to mobile phases. Pulsed pumping, in which the pump is periodically turned off, has been suggested as a means of reducing the remediation costs where mass transfer limitation is a concern. In this work, optimization of the aquifer remediation costs and design with pulsed pumping will be studied. Pumping rates and the length of pumping period will be the decision variables. Results will be compared for continuous and pulsed pumping with respect to optimal design and costs of remediation.

Optimal design and operation of land-treatment systems for petroleum hydrocarbons Kivanc, S; Ünlü, Kahraman (1999-04-22) Land treatment technology has been extensively used for the disposal of petroleum hydrocarbon containing wastes. Effective management of land treatment systems requires optimum design and operation of the system in order to achieve the fastest and most complete degradation of petroleum hydrocarbons without contamination of the environment. This paper describes a model that can be used for optimal design and operation of land treatment systems for petroleum hydrocarbon containing wastes. The model is compose...
Modeling natural attenuation of petroleum hydrocarbons (btex) in heterogeneous aquifers Uçankuş, Tuğba; Ünlü, Kahraman; Department of Environmental Engineering (2005) Natural Attenuation can be an effective cleanup option for remediation of Groundwater contamination by BTEX. One of the important aspects of the methodology that has been recognized recently is that mass removal rates, the most important parameters used to determine effectiveness of the methodology, is controlled by groundwater flow regime, which to a large extent controlled by aquifer heterogeneity. Considering this recognition, the primary objective of this research is to quantitatively describe the relat...
Modeling water quality impacts of petroleum contaminated soils in a reservoir catchment Ünlü, Kahraman (2000-05-01) Soil contamination due to spills or leaks of crude oils and refined hydrocarbons is a common problem. Estimation of spill volume is a crucial issue in order to determine the expected contaminating life span of contaminated soils. The direct procedure to determine the amount of hydrocarbon in soil is to measure the concentration of total petroleum hydrocarbon (TPH) in soil samples. The primary objective of this study was to assess the potential effects of oil contaminated soils on the water quality of Devege...
A model for optimal operation of land-treatment sites for oily wastes Ünlü, Kahraman (SAGE Publications, 2001-06-01) Land treatment as a disposal technology has been extensively used for the disposal of oily wastes. Effective management of land treatment sites require optimal operation of the system in order to achieve the fastest and most complete degradation of petroleum hydrocarbons without contamination of the environment. This paper describes a model that can be used for optimising the operation of land treatment sites for oily wastes. The model is composed of system simulator and optimisation submodels. Conceptually...
A simplified approach for slope stability analysis of uncontrolled waste dumps TÜRER, DİLEK; Türer, Ahmet (SAGE Publications, 2011-02-01) Slope stability analysis of municipal solid waste has always been problematic because of the heterogeneous nature of the waste materials. The requirement for large testing equipment in order to obtain representative samples has identified the need for simplified approaches to obtain the unit weight and shear strength parameters of the waste. In the present study, two of the most recently published approaches for determining the unit weight and shear strength parameters of the waste have been incorporated in...
