Abstract
Reduction of fresh water consumption can be accomplished when most of the water which passes over papermaking sieves is in the end directed back into paper production. As water recycles during the technological process, it gets saturated with dissolved and colloidal compounds originating from applied raw materials and chemicals. When their concentrations exceed certain level, they begin to affect paper quality seriously. Problems, due to microbiological activity, are also extensively intensified in closed systems. Critical concentrations of dissolved components, which deteriorate paper properties in dependence with specific fresh water consumption, will be determined by simulations on laboratory scale and production process models of various paper grades. Different process water treatment techniques will be tested in order to determine their suitability and efficiency for paper production with minimal water consumption. In addition, a topic of future research will be the mastering of microbiological activity by the help of environmentally friendly biocides.
