The Dr. Robert W. Okey Scholarship

WEAU SCHOLARSHIP

Due by SEPTEMBER 17, 2008

Two scholarships will be provided to students enrolled in environmental programs either in engineering or an applicable area of science or technology. Each grant will be for $1500 and both would be offered on a year-to-year basis.

TheĀ grants will be as follows:

  1. One grant for lower division students (F, S, J) 
  2. One for seniors and graduate students.

The criteria for entering are as follows:

Undergraduate grant:

  1. Son or daughter of a WEAU member or a member themselves.
  2. Response to undergraduate essay question.
  3. Be enrolled for at least 9 credit hours.

Senior or graduate grant:

  1. Be recommended by a WEAU member.
  2. Response to graduate essay question.
  3. Be enrolled for at least 6 credit hours of graduate or upper division classes.

The due date is September 17, 2008

 

THE TOPICS FOR THE
WEAU SCHOLARSHIP FOR 2008-2009

There are four new topics to be addressed in the 2008 scholarship competition two for advanced students (generally graduate students) and two for undergraduates. Choose a topic from the list, clearly and completely define the problem associated with the chosen topic and present a solution with the estimated performance. The essay must be viewed as an engineering report, be fully documented and properly referenced.

  1. Each essay must include a clear statement of the problem, the proposed solution and a complete list of sources in a reference section.
  2. Care must be given to provide the source of special or unusual aspects of your solution
  3. A full list of sources must be included in a reference section.

Topic 1.0 for advanced students

List, in descending order, the likely health problems if any, associated with each form of treatment for potable reuse of effluents:

    a. membrane polishing of the secondary treatment effluent.
    b. same with a tertiary treatment effluent
    c. a well treated tertiary effluent that is chlorinated
    d. a secondary effluent that is ozonated.

List diseases if implicated and whether they are viral or bacterial.

Topic 2.0 for advanced students

Endocrine disrupters are now a matter of serious concern in treated effluents as they enter surface water supplies. Deal with the following questions:

    a. What are the most likely sources acting as precursors contained in waste waters? b. Is bio-concentration in fish and marine animals likely to occur and what is the implication of such?.
    c. Will membrane treatment of effluents provide a means for safe removal of these materials? (compare molecular size with membrane pore size)
    d. Describe additional means of treatment for the removal of these materials.

Topic 1.0 for undergraduate students.

Endocrine disrupters are now a matter of concern as their presence in treated effluents impacts broadly on inhabitants of the surface waters: Respond to the following questions concerning this problem

    a. What is the most commonly found precursor of disrupters ?
    b. What is "sex reversal" and what are the implications?
    c. Can disrupters be removed in conventional waste treatment?

Topic 2.0 for undergraduate students:

Concerning conventional activated sludge treatment, discuss in detail the following aspects of this treatment method.

    a. What are minimum dissolved oxygen levels and why?
    b. How do oxygen demands vary for BOD removal and for nitrification?
    c. What is "bulking " in activated sludge?
    d. What is the most common source of process failure?
    e. How safe is a good effluent as a source of potable water?
