Pollution potential and ecological risk of heavy metals in municipal wastewater treatment plants sludge

Background and Objective: Application of sewage sludge contaminated with heavy metals may cause health and ecological concern. Ecological risk and heavy metals content of sewage sludge from wastewater treatment plants of East Azerbaijan province were evaluated in the present study. Materials and Methods: Nine composite samples were taken and analyzed for heavy metals. The geo-accumulation inde...

Upgrading Wastewater Treatment Plants Based on Reuse Demand, Technical and Environmental Policies (A Case Study)

Reclamation and reuse programs are an indispensable part of integrated water resource management, particularly in arid and semi arid regions. Yet, the feasibility of sustainable application not only is relied on design, operation and maintenance of wastewater treatment plants, but also could be influenced by the economical and environmental aspects of reuse demands. This study is aimed to illus...

Wastewater Treatment and Reuse

Refinery wastewater treatment and reuse

0 A tremendous amount of material has been written about wastewater treatment and reuse in recent years. This is partly due to the constantly changing technology in the field. Controversy surrounding the promulgation of regulations by the Environmental Protection Agency (EPA), and subsequent revisions, have added to the confusion. The purpose of this article is to attempt to tie this mass of in...

Tetracycline resistance genes in activated sludge wastewater treatment plants.

The development and proliferation of antibiotic resistance in pathogenic, commensal, and environmental microorganisms is a major public health concern. The extent to which human activities contribute to the maintenance of environmental reservoirs of antibiotic resistance is poorly understood. In the current study, wastewater treatment plants (WWTPs) were investigated as possible sources of tetr...
