Waste water, e.g. from heat recovery systems
Waste water from swimming pools (increased chlorine concentration)
Waste water with salt content (e.g. seawater)
4.8 Collecting tank
The collecting tank is designed for unpressurised operation: The waste water is
stored in the tank in unpressurised condition and is then pumped into the sewer
system.
The table below indicates the effective tank volume as a function of the inlet nozzle
level H in mm.
