“Increasing energy efficiency and hygienic operational safety of natural outdoor swimming pools by optimizing the DANA 1.0 database system.”

Importance of our database natural outdoor swimming pools (DANA):

The innovative pools with biological water treatment are free from by-products polluting the environment and the health of the bathers and are energetically cheaper to operate compared to the disinfected baths. According to current knowledge, they therefore represent an environmental relief. The efficient operation of a modern public pool is practically impossible without appropriate electronic operational monitoring together with operational data acquisition and documentation. Running public pools without the use of the sound background database DANA is unthinkable today.

The precursor database DANA 1.0 developed by us in the 2000s – also funded by DBU: Az 25480/23 – played a significant role in the development of the 2011 FLL guideline “Guidelines for planning, construction, maintenance and operation of outdoor pools with biological water treatment (swimming and bathing ponds)”.

Accordingly, the further development of the outdated DANA 1.0 database implemented with this DBU project is so important for the flanking and continued existence of this environmentally friendly pool technology. The continued data basis via the DANA 2.0 platform will also serve as an important aid for further European and international regulations in this area.

Together with our cooperation partner, the IT company Ravenworks GbR from Bremen, we successfully completed this DBU-funded development project, which is so central to us, in October 2021.

Performance features of DANA 2.0:

With DANA 2.0, a modern database with a cloud-based database structure has been developed that is at home in the IOT world. Protocols such as MQTT or Lorawan Sigfox applications have been integrated so that all common remote transmission protocols are accessible. DANA 2.0 prepares the way for direct cloud-based plant control, which with 5G expansion will then perspectively replace PLC control.

The user can set up his own project via the interface and does not need an external super administrator to set up the project for him as in the old version. Each measuring point can now be described visually and textually and can be integrated into own measuring protocols and maintenance protocols. Usage is intuitive: plant tours and maintenance work can be set up graphically in a plant view individually by the user admin and can be used quickly and easily by the user client for data entry.

A freely designable dashboard with many display options was developed and has proven itself in use. Newly implemented are also parameters on the hygiene situation and the energy or water consumption, which can optionally be called up on the dashboard.

Pools, water treatment plants, and lake restoration projects can be set up, managed, and hosted. Further use cases for real estate are in preparation.

International standards are included as far as possible. The operating system runs in six languages: English, German, Portuguese, Spanish, French and Danish and can be customized to another language within two days if needed.

The database system was presented at an international bathing water congress in Portugal at the 11th IOB Congress (International Organization for Natural Bathing Waters e.V.) in October 2021.

DANA 2.0 is already being used in many of the baths we manage*, supported by training that is being extended to the Polyplan-Kreikenbaum Group partner network and to future user groups.
