abstract = {An integrated membrane filtration process was developed to produce water of drinking quality out of polluted process water from small and medium-sized enterprises in the food and beverage industries. It comprised a membrane-supported bioreactor and a combined nanofiltration/UV disinfection stage. The process was implemented in demonstration scale (up to 1.5 m3/h) at a fruit juice production plant. In the bioreactor, COD removal rates \>95% were achieved. After the second treatment step, the chemical and bacteriological parameters of the treated water met the limits of the German Drinking Water Act (DWA). After authorisation procedure by the responsible authorities, the technology tested was granted approval for water reuse in the food industry. The influence of biological process parameters on the flux of the bioreactor membranes was investigated as well as backflushing and CIP cleaning procedures. In the second treatment step membrane permeability depending on different operating conditions was investigated. The treated water can be re-used for various purposes, e.g. boiler make-up water, cooling water. Amortisation periods of less than 3 years are possible, depending on the water re-use potential.},

abstract = {Hydrological and hydrochemical investigations have been carried out in the Aliakmonas river basin in northern Greece. The study aimed at providing a basis for a sustainable management of groundwater and surface water resources. Groundwater recharge derived from a water balance model amounted to 172 mm/y for the northernmost part of the catchment and decreased to 131 mm/y and 83 mm/y further east and south. For the whole river basin the modelled runoff reached 357 mm/y compared to 325 mm/y measured at the gauging station Illarion. Hydrochemical investigations confirmed the pattern of groundwater recharge within the basin. A preliminary cluster analysis yielded an aggregation of water samples into end members and their respective mixtures, representing the geogenic influences within the basin. Hydrochemical profiles along the Aliakmonas river showed a lateral subsurface influx from carbonatic aquifers in the upper part of the Aliakmonas river. While the hydrochemical study revealed significant influx from the northwestern molasse along the middle reach of the river Aliakmonas, contributions from ophiolite areas become dominant in the lower part.},
