Client Description

Waste-Management Education and Research Consortium (WERC)Typically, the environmental tasks have no known solution or the available solutions do not meet performance criteria

3

Ali Hasan

The goal of the competition is to design, develop, and test actual environmental processes for real-world problems.

Problem Statement

Task:

Emulsion techniques

Separate emulsified oil in water

Design:

Cost effective

Efficient

Robust

Ideal solution:

High degree of separation

100% water 0% oil

100% oil 0% water

4

Ali Hasan

Non-emulsion Vs. Emulsion

Project Significance 5

Increased use of petroleum creates a need to remove

emulsified oil from water before disposal

This project removes oil contaminants from the water

Safer and cheaper to dispose

Recovers oil

Needs Statement Full Scale Model:

100 GPM

Uses industrial waste oil

Uses brackish water

Bench Scale:

Emulsified vegetable oil Represents the industrial waste oil in full scale

Environmental Health and Safety (EHS) disposal

Given:

10 gallons of emulsified oil-water solution

@ 200 mg/L concentration

Must obtain one gallon of separated water and 8 ml of oil
