Abstract A major objective of the Junior and Senior Engineering Clinics at Rowan University is to introduce students to open-ended design projects. The purpose of the clinic classes is to provide engineering students with a hands-on, multidisciplinary experience throughout their college education. This type of innovative approach for allowing students to become involved in realistic open-ended design problems is beneficial for enhancing their problem solving skills and encourages them to pursue graduate studies. The engineering clinics emphasize multidisciplinary design on projects of progressive complexity. This paper focuses on the design and development of experiments to illustrate membrane technology for pollution prevention. A multidisciplinary student team conducted a t horough literature search and developed innovative membrane experiments to demonstrate pollution prevention. These experiments can be used by various disciplines in engineering such as environmental and chemical engineering.

Introduction

Membrane technology has gained wide popularity in the environmental and chemical industries in recent years. A membrane is an ultra-thin, semi-permeable barrier separating two fluids that permits the transport of a certain species or components through the barrier from one fluid to the other. Typically the water treatment industry has relied on membrane processes such as reverse osmosis, ultra- and nano- filtration. Beyond the expected use of membranes for water filtration, the chemical engineering industry uses membrane technologies for the separation/filtration of solvents so that water can meet the minimum specifications needed for a given chemical reactor. Also, membranes are used in the pharmaceutical, biomedical, food processing, and hazardous waste treatment industries. The wastewater industry has also started using membranes in bioreactors and also for tertiary treatment and wastewater reclamation. Membrane technology is also the viable solution for reclamation of wastewater for NASA space missions. Campers can now also carry portable membrane water filtration units in their backpacks that allow them the flexibility to drink water from streams, which may not be typically fit for human consumption. Finally, marine ships use reverse osmosis to remove the salt from seawater to meet the demands of the crew. The popularity of membrane technology indicates a need for changes in traditional environmental and chemical engineering curriculum. This paper describes the development of common membrane experiments to illustrate pollution prevention to engineering students. A multidisciplinary team of students at Rowan University developed these experiments in their Junior/Senior Engineering clinic class.
