Who we are

Membrane Consultancy Associates is a consultancy practice specializing in membrane technology for liquid separations, founded in Sept 2005. The principal is Dr Graeme K Pearce, a membrane technology specialist with 40 years experience in the membrane industry.

A graduate of the University of Oxford with a chemistry first degree and a chemical engineering doctorate, Graeme’s introduction to membrane technology started in BP Chemicals R&D in 1980. In 1988, Graeme was part of the core team to form BP’s Separation Company, Kalsep, specializing in membrane and filtration systems for water, wastewater, and process applications.

Graeme joined Hydranautics in 2000, where he has worked with the development and marketing of the pressurized ultrafiltration (UF) technology, HYDRAcap, and with submerged microfiltration (MF) technology.

In 2005, Graeme left Hydranautics to form an independent consultancy, working with a broad spectrum of users and providers of membrane technology, to improve the knowledge and application of membranes in water, wastewater, and process industries.

Membrane Consultancy Associates networks with other consultants in water treatment and membrane technology, to provide a comprehensive range of expertise, operating in Europe, North America, and Asia.
