A heat-sealable barrier paper having a) a carrier substrate having a front side and a back side opposite the front side, b) optionally an interlayer comprising a binder and disposed on the front side of the carrier substrate, c) a first barrier layer comprising a crosslinked polysaccharide and disposed on the front side of the carrier substrate or, if there is an interlayer, on the interlayer, d) a second barrier layer, disposed on the first barrier layer and consisting of or comprising i) an acrylate copolymer and/or ii) a wax based on a vegetable oil, the use of a barrier paper for packaging products, a method for heat-sealing a barrier paper, and to a method for producing a barrier paper.

A method for the production and/or processing of a web-shaped material, particularly paper, with at least one measuring system which records m measurement values yper measurement position over at least a portion of the width s of the web-shaped material at n different measurement positions within a fixed time interval &#x394;t. The method is characterized in that the method includes determining a rational quality number Q, the value of which for a quality of the web-shaped material that is considered acceptable lies within an acceptance range which is to be empirically determined for the production process and which has a lower limit U and an upper limit O, where U and O are in each case rational numbers.

There is disclosed a process for purification of waste waters accumulating from the production of pulp, particularly from chlorine bleaching of pulp, which comprises the combination of the following steps:

Process for purification of waste waters accumulated from pulp

There is disclosed a process for the purification of sewage containing fatty and albuminous matter. Raw sewage, which is optionally subjected to primary settling in a primary settling tank, is adjusted so that the pH is approximately the same as the isoelectric point of the main components of the proteins present in the sewage. The sewage is then mixed with an aqueous solution of a substituted anionic starch to precipitate the fatty and albuminous matter by flocculation. Following a short dwell time period, the sewage is subjected to an expansion flotation under a dispersion pressure of 4.5-6 bar. The flotation sludge is separated and a clarified effluent is obtained. The flotation sludge is sterilized by treatment with ultraviolet radiation and the clarified effluent is passed to waste.
