Method for predicting or controlling microbial status of a paper or board making process

The present invention relates to a method for predicting the microbial status of a paper or board making process and/or quality of the dry board or paper obtained from said process and to a method for controlling microbial status of a paper or board making process or quality of the dry board or paper obtained from said process. Surface level and duration of time in at least one storage tower or pulper are monitored and correlated with respective predetermined values for said tower or pulper in order to predict the risk of microbial activity.

本发明涉及一种可预测造纸或纸板生产过程中的微生物状态，以及由该过程所得干燥纸板或纸张质量的方法，同时还涉及调控造纸或纸板生产过程微生物状态，或调控由该过程所得干燥纸板或纸张质量的方法。通过监测至少一台储塔或碎浆机内的物料料位与停留时长，并将其与对应储塔或碎浆机的预设值进行关联，以此预测微生物活动风险。
