This year, ALMAWATECH GmbH was once again able to participate in the traditional Darmstadt Water Day organized by Endress+Hauser an excellently organized specialist event on the future of water and wastewater technology. As usual, the venue was the Merck Stadium in Darmstadt, which impressed not only with its inspiring atmosphere, but also with the quality of the presentations and discussions.
We would like to thank Mr. Wolfgang Hutter and Mr. Christian Gutknecht in particular for the invitation, who ensured that everything ran smoothly with their commitment and expertise.

Our contribution: Focus on industrial water recycling
ALMAWATECH was invited to give a presentation on the topic of "Industrial water recycling". Our focus was on two particularly topical and practically relevant applications:
Water recycling of vapor condensates from the dairy industry
Vapour condensates from milk processing generally have an increased organic load and significant nitrogen concentrations. These substances make the direct use of membrane systems such as reverse osmosis considerably more difficult:
- Microbial growth leads to fouling,
- High COD and nitrogen contents require high operating pressures and chemical input.
With our biologically activated filtration ALMA BioFil Compact we offer an efficient solution for pre-treatment:
Biological degradation processes significantly reduce both organic components and nitrogen compounds. This makes the downstream operation of a reverse osmosis system economically and technically viable in order to produce high-quality process water of drinking water quality - in line with sustainable water management.

Treatment of cooling tower blowdown water
Another topic of our presentation was the treatment of blowdown water from cooling towers, which contains large quantities of dissolved salts. A combination of ultrafiltration and reverse osmosis makes it possible to effectively remove these salts.
The result:
- up to 20% savings in fresh water,
- Return of the treated water to the cooling water circuit,
- Conservation of resources and cost efficiency during operation.
This type of water reuse is becoming increasingly important in view of rising energy and water prices.
Innovations in measurement technology from Endress+Hauser
A highlight of the event was the presentation of the latest measurement technology solutions from Endress+Hauser. Among other things, the following were presented:
- Compact, easy-to-integrate sensor systems for water recycling applications,
- Flowmeters with a particularly high level of user-friendliness,
- and the powerful IIoT ecosystem Netilion, which enables end-to-end remote monitoring, data analysis and online support.
Particularly noteworthy is the parameterizable commissioning wizard, which significantly simplifies the integration of new measuring probes - a real added value for all those who want to work efficiently and according to the state of the art.
As a plant manufacturer with high standards of efficiency, operational reliability and automation, we are pleased to have Endress+Hauser as a strong partner at our side, whose technologies make a significant contribution to optimizing the control, regulation and monitoring of our systems.
