Training

Microscopic Examination for the Operation & Control of Wastewater Treatment Plants

10th March 2016, Aqua Enviro Training Suite, Wakefield

Sorry this course is now full.  

We normally run the activated sludge training annually in the spring, but sometimes run the three courses again if there is demand. Please email clarehunter@aquaenviro.co.uk if you are interested.

Very few activated sludge plants have been completely free from foaming and bulking problems at some time and other plants suffer these problems on a routine basis. In a similar way poor solids removal, inefficient BOD removal, odour problems, inhibition and toxicity can all occur on a seemingly random basis. Routine sampling and chemical analysis from this is expensive, demanding and its interpretation is not always clear. By contrast microscopic examination of the microbial consortium in the treatment plant is simple, inexpensive and provides extensive information as to the likely causes of plant problems. The results can also be used to optimize the performance of the plant to ensure that effluent is as good as the plant is able to produce and that energy costs and sludge production are at a minimum.

TRAINERS:   Microscopic Examination for the Operation & Control of Wastewater Treatment Plants

Dr Nigel Horan,  Aqua Enviro BSc, MSc, PhD, FCIWEM, C.Sci, C.Env, MIWat. Nigel 2

Nigel specialises in the biological treatment of liquid and solid organic wastes.  He has undertaken internationally recognised research in these areas in his role as Reader in Public Health Engineering at the University of Leeds as well as delivering teaching across a range of undergraduate and postgraduate taught courses.  He has published several textbooks and over 120 research papers.  At Aqua Enviro he has worked at most of the UKs large wastewater treatment plants as well as a number in Europe and overseas.  He has worked on anaerobic digestion contracts to a value of over £45 million.  He routinely prepares and delivers in-house training courses for a wide range of companies throughout the UK in both wastewater treatment and anaerobic digestion.

Emma Morley emma (5)

Emma has worked at Aqua Enviro since 2001 with a focus on activated sludge in municipal and industrial treatment plants. With her keen eye for spotting Vorticella, identifying filamentous bacterial species and the sheer number of samples examined means that Emma is well qualified to be training delegates in microscopy.

Paul Lavender Paul 1

Paul has over 14 years consultancy experience in the wastewater industry.  Having originally studied environment chemistry at Leeds University, he has worked for Aqua Enviro since 2000 in which time he has been involved in developing, trialing and troubleshooting a wide range of treatment processes in both the municipal and industrial sectors.
