High-performance measuring and control technology from ProMinent is providing sustainable water treatment for municipal swimming pools in the city of Heidelberg. Economical operation ensures that all visitors can continue to enjoy the pools in the long term.
The company which operates Heidelberg's municipal pools, Stadtwerke Heidelberg Bäder, is responsible for five swimming pools with around 500,000 visitors per year. Efficient, sustainable operation is essential to the successful, long-term utilisation of the individual pools. All are therefore operated with green electricity and eco-friendly heating. To remain state-of-the-art, in 2014 the water treatment and disinfection systems were modernised at the pool on Tiergartenstrasse. The project consisted of the complete dismantling of the old systems and the installation and commissioning of new ones. The most important element in the project was the precise configuration of the metering pumps to meet the demands of the feed rates and pressure levels. The operator chose two local companies to realise this ambitious project: the IBA TechnikCenter of IBA-Aqua-Pflege-Produkte GmbH and ProMinent GmbH.
- Modernisation of the water treatment and disinfection systems in the public swimming pool
- Quick turn-around time needed due to the season starting
- Complete installation of measuring and control technology as well as several metering pumps
Installation in record time
In early May 2014, just before the start of the new season, the new water treatment and disinfection technology went into operation at the pool on Tiergartenstrasse. And despite the amount of work involved, the installation team from the IBA TechnikCenter only needed two days to complete their work. Close cooperation with the Heidelberg Stadtwerke and reliable delivery of the components also contributed to the speedy installation.
Alongside the installation of the solenoid metering pumps Beta® and the robust peristaltic pumps DULCO®flex DF4a, ProMinent's scope of delivery included the multi-channel measuring and control system DULCOMARIN® II. The bypass fittings are made from pre-assembled in-line probe housing modules, fitted with screw-in sensors for pH, ORP and chlorine. Thanks to flow control, only a small volume of sample water is needed for a quick measurement. The DULCOMARIN® II is connected to the pool's building management system by means of a CAN bus system and thus controls all the associated water circulation systems remotely.
Everyone's a winner
From the initial comprehensive consultation from IBA TechnikCenter, via the bidding phase right up to the awarding of the contract and installation, the project was managed to the utmost satisfaction of the customer, to which the open and continuous communication of all those involved also significantly contributed. Stadtwerke Heidelberg benefits from minimal maintenance and operation requirements as well as high operating safety and reliability. But the real winners are the visitors old and young who come to enjoy the city's pools, because they can relax and enjoy themselves knowing that the water is of optimum quality, wherever they go.
- Installation of high-performance measuring and control technology with the DULCOMARIN® II controller reduces operating costs
- Reduction of the chemical use thanks to precise metering increases work safety
- Successful collaboration between competent local companies means everyone's a winner
