WATER PRODUCTION FOR AQUAPONICS
WATER PRODUCTION FOR AQUAPONICS
The water production for AWARE main activities includes three stages – disinfection by ultraviolet C radiation (UVC), storage for12:00:00-24:00:00(according to water load and season) and ozonation. The water quality is monitored at these three stages, for the parameters indicated in Figure 1 below.

Sampling, Processing, and Analyses
Water samples are collected (see Figure 2) and processed within a06:00:00interval, before being shipped for the partner responsible for the analyses (Table 1). In case no processing is needed, samples are frozen and stored at-80 °Cwithin03:00:00.
For each sampling event, the date, day of the week and hour; the temperature and rain. Sampling points, indicated in Figure 2 were designated from A to I:
- Influent of primary treatment (A)
- Influent of biological treatment (activated sludge) (B)
Observations: Samples processed and analysed within12:00:00after collection.
