Flow rate and membrane life with chemical cleaning
The AQUALOOP membrane can be loaded with 1 Mio. ppm free chlorine without limitation on its 10-year lifespan. With the recommended cleaning concentration of 0.25% (= 2500 ppm) approx. 400 chemical cleanings can be conducted without limiting the lifespan. To calculate a reduced lifespan due to chlorine cleaning, the following formula can be used:
