Abstract
This WACI-project was divided into several subprojects, which were started with gathering of present knowledge and entering to laboratory and pilot tests. In some projects there were mill scale trials in water connections and internal purification systems. In the `Quality Demands of Water` subproject the process waters used in the printing paper machines of UPM-Kymmene were surveyed. Lab tests were made for the different applications like shower, washing, seal and dilution of internally purified circulation waters. In `Mechanical Pulp Washing` project the target was to study how the different water connections around the TMP washing press will affect the paper machine runnability. It was also started to develop separating technique for TMP fibre extractive. `Micro and Electroflotation` studies have been made mainly on pilot scale but also in new mill-scale unit. `Membrane Technology` research consisted of both lab, pilot and mill scale studies, where different membrane qualities with different process waters have been tested. `Evaporation` trials were made on pilot scale for different process waters and condensates and concentrates were analysed. Condensates were tested for different applications. The possibility to `Reuse Waste Water` concentrated mainly on how to remove the brown colour. `Simulations` were done to find out what will
