Drinking water
For decades STULZ-PLANAQUA, in conjunction with the specialists of the former Kary GmbH, has been providing a comprehensive and well-engineered product range for all mechanical equipment in the waterworks construction industry. Modern process engineering guarantees optimal water treatment and purification and thus the best water quality. From system planning to project management and installation to commissioning, testing, training and service, STULZ-PLANAQUA provides a comprehensive service package.
Turn-key compact systems
In addition to partial solutions, such as plants for the removal of iron, manganese and chlorine, the turn-key product range includes in particular compact units for drinking and industrial water production from groundwater and surface water. In the compact units, the proven and powerful process steps of flocculation, tube-bundle clarification and mixed-media multilayer filtration are optimally combined. The compact system thus provides maximum reliability and – regardless of fluctuations in raw water – constant pure water with minimal investment and operating costs.
Technical details
The compact water treatment system is used for the production of drinking and industrial water from groundwater and surface water. The technology is particularly applied in the removal of turbidity and discolouration, for taste and odour improvement or the removal of iron and manganese.
Plant construction
The compact systems basically have a two-line design; each line can be operated on its own. The procedural compact unit includes flocculation, sedimentation and filtration stages. Optimal flocculation formation is ensured in the flocculation chambers by the use of agitators and flocculant chemicals. The proven tube-bundle clarifier is used in the sedimentation stage for the separation of the formed flakes. The following filtration stage is designed as mixed-media multi-layer filters.
Consistent water quality
Based on these procedural combinations, the compact water treatment system provides optimal operational safety and independent of raw water fluctuations, a constant high quality of pure water.

Application-specific procedures
For drinking water treatment using Membrane technology, STULZ PLANAQUA provides both the ultrafiltration to remove particulate impurities as well as reverse osmosis for the desalination of seawater. For this purpose the processes of flocculation and filtration are combined with membrane technology.
