Page 12: Aqpure Modules
6.4 AQpure modules The core component of the AQpure system is the standard UF module for ultrafiltration. The standard UF module is included in all possible configurations of an AQpure system. Additionally an AQpure system can comprise a number of modules and accessories. The quality of the raw water intake determines, which modules are required for the water purification process. - Page 13 Pos. Module Description The standard UF module is included in all possible configurations of an AQpure system. The most basic configuration for an AQpure system comprises only this module. It comprises all components relevant for the ultrafiltration (UF) process and the basic self-cleaning tasks. If no solar package module is used, the system includes an Uninterruptible Power Supply (UPS) to put the system into a safe state in case of power failure.
- Page 14 6.5.1 External tank setup options. The external tank is not supplied by Grundfos but always sourced locally by the operating company to avoid high shipping costs. However the pressure sensor used to determine the water level in the external tank, is supplied by Grundfos. The level sensing module includes only the pressure sensor.
