System Sizing
All CalUltra UV systems are rated for a specific flow rate in water that meets the quality parameters
on page 5.
PLEASE NOTE
that increasing the flow above this rating or disinfecting water that
does not meet the quality parameters will decrease the dose and therefore compromise the
microorganism inactivation.
It is important to know the maximum flow rate that your water system delivers. If you do not
have this information, you can simply fill a 10 litre bucket with water from the mains supply and
tome how long it takes to fill up. This can then be calculated to litres per minute and the the
approriate Calmag UV unit should be chosen.
Location
Choose a location where the main cold water line is accessible. The system must be installed
after other water treatment equipment (softener or filters), but before any branches (See Figure
1). Calmag recommends that a 5 micron filter be installed
before
the UV system for a final
polishing step before the water is disinfected (included with the CalUltra 12 and CalUltra 22
models).
