This event is no longer available for registration.


Introduction to Ion Exchange Design and Operation for Industrial Water Treatment

The focus of this course is to provide a good basic understanding of the design basis and operation of ion exchange plants for water treatment, from raw water quality and pre-treatment through to monitoring, control and troubleshooting. The presentations are centred around the ion exchange process itself, explaining how ion exchange resins are manufactured and activated, the different generic resin types and how the process selection is based on the ion exchange resin properties to achieve the desired treated water quality.

This course is designed for utilities engineers, plant supervisors, chemists and those needing a better understanding of water purification by ion exchange.

He joined Rolls-Royce in 1985 working on Nuclear Decommissioning projects, during which time he became a Chartered Engineer and obtain an MBA from Newcastle University. In 1997 he was transferred to Kennicott (now Ovivo) as a Senior Manager overseeing the Installation and Commissioning Department, he is currently the Senior Manager for Ovivo UK Parts and Service.

Joe Woolley

Xtech Process Water Limited

After completing a degree in Chemical and Process Engineering and spending a short period commissioning in the municipal water sector, he spent 9 years in commissioning and project work primarily in industrial ion exchange and membrane systems. A change of company in 2009 focussed on developing his process design skills but maintained a hand in site activities, thereby providing a valuable link from conception and detailed design to commissioning and handover. In 2020, Joe started Xtech Process Water to provide design and technical support to a variety of companies typically wherever a high purity water requirement exists.

Lukasz Warachim


Lukasz Warachim graduated Technical University of Silesia in 2000 with a specialization in Water and Wastewater Treatment, M.Sc. Engineer.
