Then, the scope of the study is extended to put the results in context of the urban metabolism. The relevance of the urban water chain - with and without algae - for the urban energy balance and the urban flows of nutrients and anthropogenic micropollutants is assessed.enwastewaterresourcealgaeurban metabolism303600doctoral thesis
