Abstract: The invention relates to a method and an apparatus for reducing the water and energy consumption of a paper machine with the help of a vacuum system and optimization of web solids content as well as a use of the same. An essential feature of the invention is that, on the paper machine wire section (12), water is removed with the help of a hybrid vacuum system (1) serving first the vacuum locations needing a lower vacuum level and then those requiring a higher vacuum level in such a fashion that the hybrid vacuum system (1) removes water on different sections of the paper machine at the vacuum levels rendering the individually maximized energy efficiency. Additionally the solids content on the wire section (12) is optimized with the help of an un-felted and smooth press roll (13) adapted above the wire suction roll (3).

Abstract: The object of the invention is an apparatus for measuring dewatering in the wet end of a paper machine. What is essential in the invention is that the apparatus comprises a measuring receptacle (15) functioning at normal air pressure, in which receptacle the amount of the water (7) of the negatively-pressurized dewatering points of the paper machine is measured by means of a pressure- difference transmitter (20) and of a measuring weir (8).

Abstract: The object of the invention is an apparatus and a method for measuring dewatering in the wet end of a paper machine. What is essential in the invention is that the measuring system (26) comprises an essentially horizontal inlet pipe (10) on the machine level (11), which pipe is installed in the measuring receptacle (27), and in that the separation of air (22) is performed in an expanded pipe section (15) made in the inlet pipe (10) and in the outlet pipe (16) connected to it. A weir plate is installed in the measuring receptacle (27) of the measuring system (26), the weir plate functioning as a measuring weir (8) for measuring the amount of the dewatering flow, and from a pressure difference transmitter (20) installed on one side, which transmitter measures the height of the water surface produced by the measuring weir (8) for measuring the amount of water (7).
