Operating principle
Potable tap water enters the SmartPak cartridge through the Booster Pump. The SmartPak cartridge for the
remainder of this manual is an all-in-one twin-cartridge containing three water purification technologies. The
first cartridge combines Pretreatment media and a Reverse Osmosis (RO) membrane. The second cartridge
contains Ion Exchange resin. The SmartPak cartridge is a consumable device that needs to be periodically replaced
during the maintenance of the system.
Tap water is pretreated to protect the RO membrane from organic fouling and chlorine oxidation. The RO
membrane has 2 exiting streams: permeate (pure water) and reject. The permeate water that went through the RO
membrane is stored temporarily in the tank. The ions, particles, organic molecules and bacteria rejected by the RO
membrane are sent to the drain via the Reject Tubing.
During Dispensing mode, the Distribution Pump turns on. The RO water is pumped from the tank into the UV Lamp
(UV System). The UV Lamp emits light at 185 nm and 254 nm. It is used to reduce levels of organic molecules in
the water. The UV Lamp is a consumable device that needs to be periodically replaced during the maintenance of
the system. The RO water is then sent to the Ion Exchange Polisher cartridge to deionize the water. The Final Filter
is a membrane based filter that removes all particles and bacteria with a size greater than the filter pore size. The
Final Filter is a consumable device. Product Water is regularly recirculated to enhance the quality of water
delivered from the Direct-Q R.
