Axolot Solutions’ technology highlighted in the Finnish paper industry journal Paperi ja Puu

 

The article describes Axolot’s water purifying technology and it’s benefits to chemical forest industry – reduced water and energy consumption. Axolot’s AxoPur® electrochemical process cleans water by separating it into two fractions; clean water for reuse and a compact floc. The separated floc is self-drying over time, which makes it very suitable as an energy source for combustion. When applied to a paper manufacturing process the benefits are even higher, since the floc can be recycled in the process and used as a raw material by running it at 3.5% dry content to the couch pit. The AxoPur® system constitutes an industrial investment with a short pay-back time, not a cost, as is the case with traditional chemical and biological purification technologies. Moreover, since the AxoPur® process is rapid and compact, the cleaned water retains its elevated temperature when returned to the paper machine. The result is that the short circulation temperature of the paper machine can be raised, since the water cleaning process itself does not limit the temperature as biological waste water treatment process would. Another example of how the technology can be used is for purifying coating machine washing waters. Axolot delivered the AxoPur® concept to Colombier Finland Oy in Pyhtää last year. According to the statement by Colombier Carl-Erik Guttormsen, the coating process washing water is now efficiently purified at the mill, which supports the Colombier Barrier Coating brand and its associated environmental values.

 

Paperi ja Puu (Paper and Timber) is the main trade journal of the Finnish pulp and paper, and mechanical wood-processing industries. It is a scientific and technical publication, which publishes articles about future trends, production and export statistics, company and mill features, news, and machinery and equipment descriptions. Each issue deals with some aspects of the related technology and the issue #1 2019 the theme was “Creating bioeconomy”.
