Attention has to be paid to the chemical and physical conditions of the white water circuit and to the measurement and control of the effectiveness of various chemical additives (Table 3.12). On-line measurements and integrated process control give the best and constant performance of multifunctional chemical combinations. Of similar importance are the methods and positions for metering chemical additives to the paper production system as well as the sequence of their addition (Fig. 3.28). 

Nowadays, chemical additives are an integral part of advanced papermaking technology. Maximum performance can be achieved by tailoring their properties in
