The validation of two novel separation technologies in a ZLE concept via in-mill research at recovered paper mill Niederauer Mühle (Germany)

As economic circumstances change and environmental legislation tightens, paper mills are forced to minimise their energy and water consumption to produce minimum emissions. A competitive product based water treatment concept to Zero Liquid Effluent (ZLE) is based on the 'five-fraction model'. To remove suspended solids two novel separation...

Focused Beam Reflectance Measurement (FBRM) a promising tool for wet-end optimisation and web break prediction

The trends to increased speed and higher qualities have increased the need for wet-end control - especially for systems with on-line measuring devices and feed forward control. One possibility is the use of Focused Beam Reflectance Measurement (FBRM) to measure on-line particle counts and their dimensions in (high concentration) suspensions....
