The present invention relates to a new process for creating foam in a process for manufacturing a paper or board product. According to the present invention, certain types of antimicrobial starch is used in the creation of the foam.

Process for creating a foam utilizing an antimicrobial starch within a process for manufacturing a paper or board product

The present invention relates to determination of the microorganism content in material comprising cellulose within the pulp and paper industry. The material comprising cellulose is enzymatically pretreated and microorganisms are determined using PCR based technology.

Method for determination of microorganisms

The invention relates to a method in the wet end of a web forming process. In the method, at least one electrode pair () is placed in the wet end. The electrode pair () is supplied with a current/voltage from a power source (), so that an electric field is set up between the electrode pair (), causing the material particles in the pulp suspension in the wet end to be electrically charged in a desired manner and to move in a desired manner in the pulp suspension in the wet end. The current/voltage of the power source () is controlled by means of a measuring and control unit () so as to cause the material particles in the pulp suspension to be electrically charged and to move in a desired manner, thus allowing the retention, formation and orientation of the material particles in the pulp suspension to be substantially improved.
