Water Quality
Water quality in Flow Loop
Controlled bathing water quality in professional installations
When the LOOP function is used, the water from the shower floor is collected, filtered, and UV-purified before being sent back through the shower.
The purification takes place in a continuous loop during the shower. First, the water passes through a coarse filter, then through a microfilter, and finally it is treated with UV light. This ensures high bathing water quality during normal use — also in professional environments where operational reliability and user confidence are essential.
Flow Loop is designed so that water is not shared between users. The system only recirculates water from the current shower session.
Several purification steps
The water is filtered through both a coarse filter and a microfilter before being treated with UV light. The different purification steps help ensure stable and controlled bathing water quality during use.
No water sharing between users
Flow Loop only recirculates water from the current shower session. Each shower starts and ends with a backflush, ensuring that water is not shared between different users.
Flexible user function
The user can switch between traditional shower mode and LOOP mode. This provides flexible use in professional environments and makes it possible to combine resource savings with a familiar shower experience.
Bathing water quality
Developed for safe and documentable use
Flow Loop is developed with a focus on delivering high-quality bathing water when the LOOP function is used. The water is not classified as drinking water, but it meets strict hygiene requirements for normal shower use.
When the LOOP function is active, the water circulates from the shower floor back through the system. A pre-filter in the intake prevents hair and larger particles from entering the shower. The water then passes through microfiltration, where visible particles are removed. Before the water is sent back to the showerhead, it is UV-purified to reduce bacteria and viruses in the water.
The water quality is comparable to that of a jacuzzi and cleaner than the water in a standard bathtub. For coliform bacteria, E. coli, and enterococci, LOOP water meets the requirement of less than 1 CFU per 100 ml.
Each shower session starts and ends with an automatic backflush. This ensures that water is not shared between users and that the LOOP function only recirculates water from the current shower session.
The combination of pre-filter, microfiltration, UV purification, and backflush makes Flow Loop relevant in professional installations where water quality, safety, and user acceptance are key requirements.
User function
Two shower functions in one solution
Flow Loop has two settings:
Traditional mode
The shower functions like a regular shower without recirculation.
LOOP mode
The water is recirculated from the shower floor, purified, and sent back through the shower.
The LOOP function starts automatically 30 seconds into the shower when the function is selected. With the press of a button, the user can control whether the shower should be in LOOP mode or traditional mode.
This flexibility is important in professional environments because the solution must be easy to understand and use for different types of users.
