Wastewater Treatment and Reuse

Municipal wastewater treatment using constructed wetlands

The aim of the paper is to present alternative to conventional (i.e., the commonly used biological treatment plants) wastewater treatment systems, appropriate for small communities and settlements. These systems are the natural treatment systems. The emphasis here is given on constructed wetlands (CWs). First, advantages and disadvantages of these systems are presented compared to conventional ...

Municipal Wastewater Treatment Using a Hollow Fiber Membrane Bioreactor

A bioreactor equipped with hollow fiber microfiltration membranes was applied for wastewater treatment. Removal of chemical oxygen demand (COD) and biochemical oxygen demand (BOD5) was investigated. The experimental setup consisted of influent and effluent tanks, and membrane modules using Polyvinyl Di–Fluoride (PVDF) hollow fibers. The operation program included suction and backwash...

Odorous compounds in municipal wastewater effluent and potable water reuse systems.

The presence of effluent-derived compounds with low odor thresholds can compromise the aesthetics of drinking water. The potent odorants 2,4,6-trichloroanisole and geosmin dominated the profile of odorous compounds in wastewater effluent with concentrations up to 2 orders of magnitude above their threshold values. Additional odorous compounds (e.g., vanillin, methylnaphthalenes, 2-pyrrolidone) ...

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...
