Implementation of innovative, resource-efficient urban water systems depends on wide-ranging cooperation

By: European Commission DG Environment

Urban water systems manage water resources in urban areas, including water supply and waste-water treatment and disposal. Although radical innovations to water systems have been suggested in recent research — for example, separating the waste water produced so that it can be used for different purposes, such as heat recovery or re-use — in Germany, these have generally only been implemented at house or block level in pilot schemes, say the researchers.read more »

Tall sedge in biofiltration systems removes the majority of dissolved phosphorus from greywater

By: European Commission DG Environment

The pathways for removal of dissolved phosphorus within biofiltration systems have been examined in a new study. Over 95% of phosphorus was removed over the study period, with the majority of phosphorus stored within plants. The researchers say the findings demonstrate the value of using suitable plant species within biofiltration systems to treat polluted water.

Iron-coated brown seaweed used to remove arsenic from water

By: European Commission DG Environment

The removal of arsenic from water using a brown seaweed (Sargassum muticum), coated with iron hydroxide, has been tested in a recent study. Under optimal pH conditions, the method removed 100% of the arsenic, indicating the viability of this method for treating contaminated water.read more »
