Treatment”. Many MG <strong>and</strong> SG members have c<strong>on</strong>tributed to these books.• New activities: The coming year we will organise some 1-2 days workshops ormeetings <strong>on</strong> more specific topics, e.g. PHB producti<strong>on</strong>, Populati<strong>on</strong> Dynamics, orEBPR processes. More info follows below.• The next specialized MEWE c<strong>on</strong>ference will be held in 2012 in Ann Arbour,Michigan. Professor Nancy Love will organise the c<strong>on</strong>ference together withLutgarde Raskin, Trina McMah<strong>on</strong>, Steven Liss, Dan Noguera, <strong>and</strong> others.Trina McMah<strong>on</strong>, SecretaryPer Halkjær Nielsen, ChairNEW NAME OF THE SPECIALIST GROUP: MICROBIAL ECOLOGY ANDWATER ENGINEERING (MEWE)The <str<strong>on</strong>g>Specialist</str<strong>on</strong>g> <str<strong>on</strong>g>Group</str<strong>on</strong>g> ”Activated Sludge Populati<strong>on</strong> Dynamics” (ASPD) has changed itsname to ”<strong>Microbial</strong> <strong>Ecology</strong> <strong>and</strong> <strong>Water</strong> <strong>Engineering</strong>” (MEWE). This was decided at therecent specialized c<strong>on</strong>ference in Aalborg, Denmark in May 2009.The ASPD SG was established in 1989 <strong>and</strong> has since been very successful with manymembers <strong>and</strong> activities. The main rati<strong>on</strong>ale for the name change was the fact that manyother topics besides activated sludge were, <strong>and</strong> are intended to be, included in the work ofthe SG. Previous c<strong>on</strong>ferences focused <strong>on</strong> the activated sludge process because thisprocess is by far the most dominant wastewater treatment process worldwide <strong>and</strong> manyimportant scientific <strong>and</strong> operati<strong>on</strong>al problems (still) need to be solved. However, theimpressive advancement of technologies <strong>and</strong> methods for the study of unculturedmicroorganisms <strong>and</strong> the new knowledge this has provided our wider discipline over thepast few years has created the opportunity to assess biological wastewater treatment morebroadly. The SG c<strong>on</strong>tinues to pursue similar fundamental microbiological questi<strong>on</strong>srelated to mixed microbial ecosystems that go bey<strong>on</strong>d activated sludge, includingbiofilms or granules, membrane bioreactors, nutrient recovery strategies, <strong>and</strong> bioplasticsproducti<strong>on</strong>. The comm<strong>on</strong> themes in these pursuits are general microbial ecology <strong>and</strong>management of the microbial communities using more rati<strong>on</strong>al engineering design.Our visi<strong>on</strong> is that the SG will serve researchers <strong>and</strong> practiti<strong>on</strong>ers working at the interfaceof microbiology <strong>and</strong> engineering. The SG will try to encompass most major systems inwastewater treatment <strong>and</strong> focus <strong>on</strong> the comm<strong>on</strong>alities – the quest to underst<strong>and</strong> <strong>and</strong>manage the microbial world. Many of the organisms are similar across systems, <strong>and</strong> theanalysis toolbox is essentially the same. In order not to become too broad, the SG will nottry to encompass all biological processes of interest to <strong>IWA</strong>. Thus, we will not coverbiofuels, food producti<strong>on</strong>, anaerobic digesti<strong>on</strong>, or other biological processes currently_________________________________________________________________________________________________<strong>IWA</strong> <str<strong>on</strong>g>Specialist</str<strong>on</strong>g> <str<strong>on</strong>g>Group</str<strong>on</strong>g> <strong>on</strong>: <strong>Microbial</strong> <strong>Ecology</strong> <strong>and</strong> <strong>Water</strong> <strong>Engineering</strong> 4Newsletter December 2009
served by other SGs. The new SG is limited in scope to wastewater treatment <strong>and</strong>beneficial use (e.g. for nutrient recovery or bioplastics producti<strong>on</strong>).This initiative is also in line with recent meetings between <strong>IWA</strong> <strong>and</strong> ISME (Internati<strong>on</strong>alSociety for <strong>Microbial</strong> <strong>Ecology</strong>) about a str<strong>on</strong>ger link between the two organizati<strong>on</strong>scovering water <strong>and</strong> wastewater treatment, food producti<strong>on</strong>, <strong>and</strong> energy producti<strong>on</strong>.CURRENT MANAGEMENT TEAM OF THE SPECIALIST GROUPPer H.
