Bioaugmentation for enhanced wastewater treatment performance depends on survival, maintained activity and retention of the inoculated microorganisms in the reactor. Biofilms could be suitable mediators of bioaugmentation due to the retention of the immobilized cells and the protection offered by the biofilm matrix. The overall objective of this study was to investigate the potential of […]

This paper evaluates the accumulation of the heavy metals cadmium, chromium, copper, nickel, lead, zinc and the effect of deicing salt in two Vegetative Filter Strips in an eight years old facility in southern Malmö. The two Vegetative Filter Strips were the road shoulder and the last step in the treatment facility after a swale, […]

The city Cochabamba in Bolivia faces increasing environmental problems and health risks due to insufficient wastewater treatment in peri-urban areas. This study evaluates the treatment efficiency of a horizontal subsurface flow (HSF) constructed wetland, built by the foundation AGUATUYA, and investigates the applicability of the method in Cochabamba. The wetland reduces BOD5 by 80–97 %, […]

New technologies in the water sector can make treatment processes more efficient at lower total cost and with less environmental impact, but it is often difficult for new technologies to get from research to market. Therefore EU has proposed a number of measures to facilitate uptake of new technologies. One is the implementation of testing […]

The development of the ancient water supply of Greece is described in brief and the central causes for why Greece has so many different technical solutions discussed. The probably most important reason to the multitude of technical solutions is that the city-states in general had a far-reaching independence. Thus, many city engineers could develop their […]

Iron is an important nutrient, and is included in e.g. haemoglobin. It is excreted in very small amounts. High intake, mainly from Fe in medicines or supplements, may cause bloody diarrhoea, and later acidosis, liver- and kidney damage and heart failure. Fe from drinking water is infrequently discussed. 1. Cows and calves on a farm […]
