Problem Solver
Donald Merrill
I am a Chemical Engineer graduate (1974) from the University of New Brunswick. I would like to work in chemical engineering, mostly as a Quality Control analyst, checking other engineer's work for scientific reasoning and precision. I have experience with Atomic Energy of Canada, Ethyl Corporation and NB Power.
Areas Donald Merrill is Knowledgeable in:
Chemical Engineering
Techniques Donald Merrill Uses:
Scientific reasoning and engineering principles, combined with persistence, trial and error validations, and researching similar problems for validation.
Donald Merrill's Problem Solving Skills:
- Lead-in-air testing

- Potable water testing and chlorine control
- Cathodic protection - anode installations and testing
- Gas Turbine engine overhaul and repair
- UST Precision Leak Testing
- Automotive tune-ups
- Boiler Water testing
- Bioremediation and spill investigations
- Environmental Impact Assessment Compliance
- RBC sewage remediation and testing for BOD's and COD's
- Nuclear Operations and Licensing
Donald Merrill's Problem Solving Experience:
- The potable water supply at the Belledune Generating station under construction, was river water passing through a sand filter with chlorine addition after the filter. The river quality obviously fluctuated, so I suggested that the chlorine addition system should regulated by a feedback control system from a chlorine sensor upstream from the filter. I also suggested carbon filters be installed at all the drinking water locations on the construction site.
- I designed a foam fractionator, installed on a fish farm tank system, which was part of a conversion to a recirculating system, in order to enhance fish growth during winter months.
- While working at the NB Power Belledune Construction site for a 450 MW generating station, we discussed the possibility of an ammonia leak from the nearby fertilizer plant. I suggested that we should install carbon filters on our air exchange systems in the administration building during construction, and all buildings during the operation of the plant. I do not know if these measures are in place as I was on a term contract.
