Special issue on biofiltration

Article Abstract:

The special issue on biofiltration discusses topics relevant to biofilter engineering ranging from fundamental processes to improving biofilter designs and operating conditions. Biofiltration was first used in controlling odors and the original biofilters merely consisted of perforated pipes laid over soil beds in outdoor trenches. There are currently over 500 biofilters in use in Europe for treating odors at coffee-roasting plants, meat-packing plants and in other manufacturing plants. Biofilters, biotrickling filters and biological scrubbers are the three most popular designs because they can be designed and operated inexpensively.

Article Abstract:

Conductor Ilya Musin has been well known in the former Soviet Union for many years, but is only now, at the age of 92, starting to become known in the UK. He has been giving conducting masterclasses at the Royal Northern College of Music and at the Royal Academy of Music, and is soon to conduct a concert at the Barbican. He has trained many conductors who later became famous, and has established a very particular style of conducting.
