The waste water treatment plant at our Syktyvkar mill treats our own industrial waste water and also the waste water from the local community. In 2016, we embarked on a new project to modernise the waste water treatment works which will allow municipal and industrial waste water to be mixed before entering the treatment plant. Community waste water supplies the micro-organisms required for the aerobic waste water treatment plant with the required phosphorous- and nitrogen-containing nutrients. In the past, these nutrients reached the waste water treatment plant in an unbalanced way due to the daily patterns of community use. Through our investment in new storage tanks and the mixing chamber, these highly valuable nutrients can now be introduced evenly throughout the day – improving the operation of our waste water treatment plant and saving on nutrient costs.
