The Three Technological Codes for Pool Water Quality Management in Europe and America

September 11, 2025

While domestic swimming pools are still troubled by complaints about chlorine odor, European and American countries have established an "invisible protection" water quality management system through technological iteration. These scientific solutions are redefining the standards for healthy swimming pools:

1. Chlorine-Free Disinfection System: A Revolution in Safety

The new regulations issued by Germany's Federal Ministry of Health in 2023 stipulate that public swimming pools must adopt new types of chlorine-free disinfectants. Experiments have shown that these disinfectants can kill 99.9% of pathogens within 30 minutes, completely eliminating trihalomethanes, a carcinogen derived from chlorine disinfection. After Munich Water Park switched to this technology, complaints about children's skin irritation dropped by 91%.

2. Intelligent Centralized Water Quality Control System

The AquaGuard system developed in the Netherlands automatically detects 8 indicators every 15 minutes, including pH value, ORP (an important indicator for measuring the disinfection effect of swimming pool water, with a minimum requirement of 650mV), and turbidity. It precisely controls the slow-release device of new disinfectants through AI algorithms. After the Royal Swimming Pool in Amsterdam was connected to this system, the waste of chemicals was reduced by 37%, and the water quality maintained the EU drinking water standard (total bacterial count <100 CFU/mL) throughout the year.

3. Ecological Circulation Closed-Loop Design

The certification for "green swimming pools" in Northern Europe requires the installation of a diatomite filtration system (with a precision of 1-3 microns) combined with new disinfectants to achieve 50 days of no water replacement. Additionally, waste heat recovery devices can reduce energy consumption by 30%.
The Malmö Sports Center in Sweden, relying on this system, saves 12,000 tons of water annually and has won the EU Gold Award for Sustainable Development.
