Process engineering tools to reduce river in-stream pollution

This paper is focused on new possibilities for in-stream pollution control, such as automated systems for real time pollution counteraction based on advection-dispersion models for pollutant transport in rivers. Important related issues are addressed: steps to undertake for in-stream pollution control; the use of process engineering (PE) tools to fulfil these steps; and development of models for pollutant transport to be further used in control. The paper presents a case study involving a Scottish stream.
