Abstract

As environmental regulations increase and get stricter, green engineering novel solutions become more appealing to industry. Green engineering approaches look into obtaining new designs/methods that are environmentally benign and also economically profitable. This paper presents a pollution prevention class module that focus on water/wastewater management. Its primary objective is to provide the engineering students with a series of tools to design optimal industrial water networks.

Introduction

Water is a key element for the normal functioning of the chemical and petrochemical industry. Steam stripping, liquid-liquid extraction and washing operations are among the many processes present in refineries and chemical plants where water is intensively utilized.

Several procedures have been proposed to design economical wastewater treatment. With a few exceptions, these procedures rely on the application of certain rules of thumb. The current installations usually merge several waste streams and use appropriate technologies in series to clean this stream before disposal. These are therefore, end-of-pipe non-distributed wastewater cleanup solutions. Several papers discuss these options. Belhateche (1995) offers a complete discussion of these technologies.

Starting in the eighties and increasingly in the nineties, water re-use started to become popular as means of reducing the total amount of water intake. This, in turn, not only saves upstream treatment of raw water but also reduces wastewater treatment costs. In addition, the concept of distributing the treatment among the various polluted streams and even decentralizing it is gaining acceptance. Industry and the EPA in the US are also seriously considering and discussing the advantages and disadvantages of zero-liquid discharge solutions as the ultimate goal of green water utilization in process plants. † To whom correspondence show be addressed. ‡ University of Oklahoma.
