Notes:
The values for the inorganic substances were measured in a
sample of water which was taken after two minutes' ope-
ration at a flow of 4.4 litres per minute, 80 % recovery and
a challenge water with a salt content of 800 mg per litre at
a temperature of 20 °C. Test laboratory: VVL, Stockholm
(Sweden).
The values for the organic substances were measured in a
sample which was taken after two minutes' operation at a
flow of 2.8 litres per minute, 80 % recovery and a challenge
water to which was added each substance in question to a
concentration which is 100 times higher than the lowest de-
tectable quantity at a temperature of 10°C. Test laboratory:
AnalyCen, Lidköping (Sweden).

Microbiological testing was carried out under a range of
operating conditions with a challenge water containing a
very high number of microorganisms. The water samples
were collected weekly after operating times of 20 and 40
seconds and 1, 2, 6, 12 and 18 minutes.
Test laboratory: SVELAB, Jönköping (Sweden).
