Performance Evaluations of Pump-and-Treat Remediations
نویسنده
چکیده
One of the most commonly used ground-water remediation technologies is to pump contaminated waterto the surfacefor treatment, Evacuating the effectiveness of pump-and-treat rernediations at Superfund sites is an issue identified by the Regional Superfund Ground Water Forum as a concern of Superfunddecision-makers. The Forum is a group of groundwater scientists, representing EPA’s Regional Superfund Offices, organized to exchange up-to-date information related to ground-water remediation at Superfund sites.

Chemical Enhancements to Pump-and-Treat
Conventional pump-and-treat technologies are among the most widely used systems for the remediation of contaminated ground water. Within recent years it has become recognized that these systems can require protracted periods of time to make significant reductions in the quantity of contaminants associated with both the liquid and solid phases which constitute the subsurface matrix. Evaluating t...

Abstract Background: Erectile dysfunction (ED) is common in cardiovascular disease (CVD) and indicates a complication of coronary artery bypass graft surgery (CABG). This study was designed to evaluate the status of erectile dysfunction in patients with CAD before and after CABG surgery. Methods: We designed a prospective cohort study on male patients candidates for elective on-pump CABG...
متن کاملAn Experimental Investigation into the Effects of High Viscosity and Foamy Oil Rheology on a Centrifugal Pump Performance
This paper presents the effect of high viscosity oil and two-phase foamy-oil flow on the performance of a single stage centrifugal pump. As a part of this, the applicability of a pipe viscometer to determine the foamy oil viscosity is investigated. Unlike previous studies, a sealed fluid tank is used in a closed flow loop to allow conditioning the two-phase mixture to create foamy-oil. Furtherm...
