About Mickley & Associates

Background & Experience (test)

Mickley & Associates is a Boulder, Colorado-based consulting science and engineering firm specializing in water and wastewater applications of separation and treatment technology.

We offer a wide range of services, from research and development through permitting of effluent stream disposal. We can assist in one specific area or provide ongoing assistance through months and years of program development. Our strong research and development capabilities combined with traditional engineering have proven attractive for clients considering:

  • Feasibility studies
  • Evaluation and selection of processing alternatives
  • Process research and development
  • Lab-scale, bench-scale, and pilot performance studies necessary for evaluation, demonstration, and scale-up
  • Membrane and process technology
  • Environmental assessments and evaluations
  • Industry surveys
  • Waste recycling, reuse, and disposal
  • NPDES permitting
  • Master planning of technical projects
  • Technical problem solving through study, testing, and analysis

Our associates bring their particular areas of expertise, making Mickley & Associates an association of consulting scientists and engineers with decades of experience and relatively low operating and overhead costs.

A major area of focus has been membrane and process technology. We have researched, developed, tested, and evaluated membrane products (membranes, devices, and systems), as well as designed pilot and full-sized systems and supported their permitting and startup. Since membrane systems are frequently interfaced with other treatment steps in hybrid processes, we are necessarily experienced with a wide range of water and wastewater treatment technologies, including innovative new technologies. We have developed expertise in the disposal of membrane concentrate and other waste products.

As a reflection of our work focus, of our last 30 projects:

  • 19 have been membrane-related
  • 13 have involved laboratory research (on our part)
  • 9 have performed feasibility studies
  • 7 have developed reference books or documents
  • 7 have developed software
  • 3 have conducted industry-wide surveys
Dr. Michael Mickley's Membrane and Desalination background and experience

Dr. Mickley has over 34 years of experience in the field of membrane and desalination technology, beginning with thesis work for graduate degrees. This experience ranges from the theoretical to the practical and includes research, development and manufacturing experiences with both products and processes, consulting, giving invited presentations in the U.S. and Europe, and the teaching of a graduate school course in membrane technology.

Graduate School -- This work at the University of Colorado was in connection with the use of membranes in the biomedical industry.

  • Master's Thesis - concerned with the mathematical modeling of an artificial kidney membrane device.
  • Doctoral Thesis - involved the theoretical modeling of mass transport through synthetic membranes and the experimental determination of concentration gradients and fluxes through membranes using a laser interferometer.

Cobe Laboratories -- In 1976, Dr. Mickley began working with Cobe Laboratories of Lakewood, Colorado, a medical device company whose products included hollow fiber and flat plate membrane artificial kidneys.

  • As process controller of the hollow fiber artificial kidney manufacturing process, Dr. Mickley performed a design optimization of the product, developed quality control procedures, and improved the manufacturing yield.
    As manager of Advanced Projects Department, he had full technical responsibilities for the development of a new product line - a system of hardware and software devices for continuous separation of plasma from blood by means of microporous membrane technology and centrifuge technology.
  • In the same position, he had full responsibility for a membrane development program aimed at the in-house manufacture of less expensive, high quality membranes for several Cobe products. He developed a new cellulose solvent system for use in membrane production, cast flat sheet membranes and spun hollow fiber membranes at a laboratory scale.

Coury and Associates -- In 1980, Dr. Mickley began work at this small engineering services and consulting company whose work included process research and design for the geothermal, desalination, water treatment and energy industries. Most of the work did not involve membranes per se, but much of it involved water treatment.

  • Developed selective ultrafiltration process that utilized complexing agents to modify transport properties of selected solutes for their removal and recovery.
  • Determined mechanisms and conditions under which silica scales reverse osmosis membrane devices.

Mickley & Associates -- Since the formation of Mickley & Associates in 1984, several projects have involved membranes.
