The pulp and paper industry requires sophisticated water and waste water treatment processes from a provider with experience.
Hager + Elsässer covers all tasks of water and waste water treatment, both for pulp production and for the production of paper, cardboard and toilet paper.
Our product portfolio ranges from process water plants satisfying the most stringent demands and catering to the highest volumes, to waste water treatment up to and including quality suitable for direct discharge into lakes and rivers, which may far exceed BREF standards. Recycling properly treated waste water can make a major contribution to cost-effective environmental protection.
We have suitable standard plant concepts for all plant sizes and all tasks, which are optimally adapted to customer requirements and integrated into existing processes. Our satisfied customers over the past 40 years and more include both smaller mills with plant capacities of less than 100m³/h and small loads of less than 1 ton of COD/d, and large-scale, internationally operating manufacturers handling capacities of several hundred m³/h and waste water loads of more than 100 tons of COD/d.
The paper and pulp industry is subject to increasingly stricter requirements concerning the quality of the water to be discharged or recycled.
As a result of widely varying waste water legislation and discharge regulations worldwide, some of which far exceed the BREF standards of the European Union, the requirements placed on waste water treatment are increasingly high.
By taking part in national and international research activities and by working closely together with pulp and paper machine fitters and the suppliers of the production additives, Hager + Elsässer’s engineers are always at the cutting edge of water and waste water treatment.
This means that when new processes are launched on an industrial scale, we’re there with the corresponding process and waste water solutions. We also take future requirements into consideration in our plant concept – which means that the plants we supply are future proof.
