Technologies

The improvement of effluent quality by using special process technologies has become more and more established in the water and waste water technology.

By using trend-setting technologies and techniques, STULZ-PLANAQUA GmbH already meets the high demands of future guidelines.

These will be the priorities in the coming years. In order to realize the improvement of effluent quality, special fixed-bed and membrane technologies are used both for new plants and in the course of expanding and modernizing existing plants. STULZ-PLANAQUA GmbH is addressing these tasks with high professional expertise.

In the industrial sector, STULZ-PLANAQUA GmbH provides “End of pipe” solutions, recycling of partial and total flows and sludge treatment plants.

In the desalination of sea, brackish and waste water, numerous plants, especially using evaporation technology, have been finished.
