NAQWA® SWR Cartridge (1) is a track membrane located inside a soft bag which serves as an external preliminary filtering bag ( the bag retains mechanical particles, ooze, tangle, etc). The track membrane located inside the external bag is welded up along its perimeter and fitted with a coupling for release of the recovered drinking water through the soft outlet tube (2) connected to the coupling. The track membrane is wrapped around a metallic stainless frame. The frame provides rigidity to the cartridge and keeps it immersed in water in vertical position.

NAQWA® SWR OPERATION STEPS (Fig.1)

NAQWA® SWR operation

• 1. Prepare a container for recovered drinking water (4) (a drinking water vessel, a plastic bottle with a cut top, a suitable package, etc.).
• 2. Fill the raw water container (2) with raw water and locate it 30-100 cm higher than the container for recovered drinking water (4).
• 3. Take NAQWA® SWR out of the transportation case and remove the tube plug (5) from the outlet tube (3).
• 4. Immerse NAQWA® SWR cartridge (1) into the raw water container (2), keeping the free end of the outlet pipe (3) off the container.
• 5. Lightly suck the air out of the outlet tube, the purification process will start within 5 seconds. If the air is not sucked out of the outlet tube the cartridge will get soaked up with the raw water by itself and the purification process will begin in 10-15 minutes.
• 5.1. Suck out the air with the start up 50 ml syringe (supplied optionally). The cartridge (1) should be fully submersed in the water.
DO NOT USE THE START UP SYRINGE FOR BACKWASHING THE FILTER!
• 6. Place the free end of the outlet tube into the container for he recovered drinking water (4).
NOTE: At the beginning the recovered drinking water will flow as a current the intensity of which may decrease with time and after a while NAQWA® SWR will start operating in its normal “drop-by-drop” mode.
