Huber launches kit for industrial market – stand F30
Huber is launching two new products. The Huber RoDisc Micro Screen has been designed for fine screening and polishing effluents in place of sand filters. It can be used to ensure compliance with discharge consent standards or to allow plant water to be reused. The screen comprises a series of discs fitted with woven mesh down to 10 micron apertures, which are slowly rotated on a central shaft supported above water level. Effluent flows into the discs and filtrate is collected from the outside, ensuring a complete barrier to the solids. Huber is also launching its complete
wastewater treatment package and water recycling plant, which it says is ideal for
training providers. With infrastructure development acknowledged as one of the biggest challenges facing the environmental sector, the exhibitor line-up underlines the growing interest in the sector from construction and civil engineering companies, with big names such as Balfour Beatty, Costain, BAM Nuttall and May Gurney signed up, as well as Bank of Ireland and Clydesdale Bank. “For public, private and third-sector

process water for plastics recycling. The plant can be designed to meet the required standard for recycling, at say 80% for first-stage washing, treating the surplus by membrane bioreactor for discharging into river or sewer.
Timely release on ozone treatment

Ozonation of Water and Waste Water: A Practical Guide to Understanding Ozone and its Applications, 2nd Edition.
by Christiane Gottschalk, Judy Ann Libra and Adrian Saupe
This updated version claims to add some “missing elements” that increase the guide’s . Unfortunately, if you missed the first edition it is
hard to find these. However, the book is comprehensive and contains information covering all aspects of ozonation. The book is split into two distinct parts, the first covering
background and touching on toxicology, reaction mechanisms and full-scale applications, and the second part covering experimental design, equipment and analytical methods, mass transfer, reaction kinetics, modelling of ozonation processes and application of ozone in combined processes. It is aimed at water industry professionals and researchers looking to develop and enhance their knowledge of ozone, and will provide a useful reference for students embarking on a career in the water industry who have an interest in ozone and ozonation. In trying to use it as a practical reference book there are some
drawbacks, in particular in the area of case-studies and costs. This guide has made the classic error of putting monetary values against costs, which soon become outdated due to inflation and

exchange rate fluctuations. It would have been better if the authors had presented information on energy consumption and related applied ozone dose rates to kWh of energy required, allowing future generations to use the guide as a benchmark. The experimental design section is useful and has some good generic applications outside of ozone applications but one could question the value it adds to a very specific topic. Ozone has been used widely by industry professionals for a
several decades and has been in and out of vogue depending on the issues of the day. What would have been interesting for the authors to review would have been the rate of ozone adoption on a year-by-year basis to show readers that ozone still has a major part to play in the future of water and wastewater treatment. In light of the concerns about energy and climate change, they could have helped the wider community by putting ozone in the context of other technologies, identifying where and why ozone should be used in preference to its competitors. Overall, the book is a useful guide, and with an increase in
oxidation and advanced oxidation processes due to emerging contaminants in water and wastewater, and more stringent control of micro-pollutants in discharges to the environment, the update is timely. Whether or not it increases interest in ozonation and marks the return of a technology that seemed to be capable of solving many problems, only time will tell.
professionals, policy makers, consultants and financiers – in fact everyone involved with sustainable waste and resource management – no other event offers the same opportunity to do real business, learn about the latest technology and policy developments, catch up with key legislative and policy issues, and network with colleagues,” says CIWM chief executive Steve Lee. Exciting new developments for 2010 include
more networking facilities on the exhibition floor and a low carbon demo arena in the Vehicles & Plant Zone which will include electric and hybrid drive vehicles, plant and equipment. ■■■
