Process Engineering

The research focus of the Process Engineering Department (ENG) ranges from current and future wastewater and drinking water treatment problems, as well as water pollution control and resource reuse. Our long-term goal is to develop sustainable concepts of the water and nutrient cycle in residential areas.

It’s no secret that urine contains valuable nutrients – or that diluting them with water which is then flushed into sewers is not the most sustainable way of managing this resource. But how can urine be kept out of wastewater? Eawag has been investigating this question for many years, and one answer is to use a urine-diverting toilet to separate it “at source”. What may sound simple turned out in practice to be a tricky task, and several generations of toilets were needed to optimise the source separation technology to the point where it can be more widely deployed.  Read more

A new study by an interdisciplinary team from Eawag has shown that substances from agriculture affect living organisms in rivers and streams to a greater extent than treated wastewater, which has less impact on the species composition of microorganisms.  Read more

By recovering nutrients from urine, we develop a sanitation system, which produces a valuable fertiliser
We develop reactors for the separate treatment of urine, feces and water directly in the toilet.
Inadequate access to microbiologically safe drinking water continuously threatens the health and well-being of more than a billion people, primarily in developing countries
