System stability Production conditions and parameters can be quite different according to the wide range of different paper and board grades. Papermaking succeeds even with highly loaded process water in a closed cycle, i.e. effluent-free, production. However, process conditions have to be stable to reach the required product quality and high production efficiency. Steadiness and
