Schemes for University Lecturers Industrial Secondment Scheme: Case Study Ozone Treatment of Drinking Water
Chedly Tizaoui graduated with a first class honours degree in Chemical and Process Engineering in 1996 and obtained an MSc in solid/liquid extraction in 1998. He received his PhD from the University of Bradford in 2001 for work on a novel ozonation process in water treatment. He was EPSRC sponsored Research Assistant at University of Bradford from 1998 until 2001 prior to his appointment as lecturer in 2001. Why a secondment? Chedly has a strong interest in and experience of teaching and training undergraduate and postgraduate students in the areas of water and wastewater treatment processes. The aim of the secondment was to gain exposure to industrial practice with a view to improve the industrial relevance of the modules he taught. In Yorkshire Water Services (YWS) Ltd, a number of treatment sites use ozone to primarily remove trace organic compounds (e.g. pesticides) and disinfect water. Operating ozone systems efficiently is a challenging process since these systems are relatively new to the water industry and present a certain level of complexity. A six-month project related to ozone treatment sites was agreed with YWS. The secondment offered the opportunity to get familiar with typical water treatment processes and to carry out detailed hands-on work on ozone treatment systems. The objectives of the secondment were: Personal objectives
University objectives
Company objectives
Project objectives
Yorkshire Water Services Ltd Yorkshire Water Services (YWS) Limited is part of the Kelda Group Plc. The group provides water and wastewater services to customers in the UK and the USA and employs over 3,300 people. The main activity of YWS is the collection, treatment and distribution of around 1.24 billion litres of drinking water each day. The company also collects, treats and disposes of about one billion litres of wastewater every day. It has a grid system, which is continuously improved, containing 700 water and wastewater treatment works and 120 reservoirs and operates 40,000 miles of water and wastewater mains. YWS was voted as the Utility Company of the Year in 2004, 2005 and 2006. Benefits All of the objectives of the secondment were met in full. Chedly gained hands-on industrial experience in ozone processes applied in the drinking water industry, and a good working knowledge of the control and data acquisition tools used in the water industry (e.g. Supervisory Control And Data Acquisition (SCADA)). The experience is being used to support the teaching of Civil Engineering undergraduate students and the development of a new MSc course. Several case studies supported by data from the secondment have also been prepared to complement lectures. A long-term link and collaboration with Yorkshire Water Services have been established. Chedly’s contacts in the company helped, for example to facilitate site visits for his students and initiated collaborative research projects and future consultancy work. ‘In my view the Royal
Academy of Engineering’s Industrial Secondment
scheme offers a win-win case to all parties. I
highly encourage other colleagues to benefit from
the scheme. It has been a great success with
Yorkshire Water Services.’ Statement from the Industrial Host ‘The six months that Chedly
was working with us was very constructive, and those
who came into contact with him were impressed with
the work he carried out for us. Whilst we (as a
company) were able to give him an insight into our
operational practices and the constraints that we
have to deal with, we benefited from Chedly bringing
a completely different perspective to our issues;
it's been an education!’
