Out of range - solution
If low use NaCl booster system - See
later or contact Adept
If low use NaCl booster system – See
later or contact Adept
Use water softener or automatic CIP
system. Contact Adept
Not for this kind of water

IMPORTANT:
The BacTerminator can run with conductivity below 100 µS/cm and chloride content below 20 mg/l
without brine dosing. If you have an application in this area and want to run without brine dosing Please contact Adept Water Technologies A/S.

Conductivity and chloride content:
Below scheme is showing the free chlorine production in ppm, at a given water quality (conductivity and
chloride content ) This amount of free chlorine is produced at the maximum performance at a given system,
flow and effect, 480 W*h pr. m3 of water. By this table it is possible to calculate power consumption and
system performance.

Free chlorine content is shown in ppm.
Water quality outside this scheme – low conductivity or chloride content – use booster or contact Adept.
Booster module for low conductivity and/or chloride content.
The booster module dose a small amount of brine to the water and rise conductivity and chloride content.
The booster is a fully automated brine dosing system where only NaCl has to be added in solid form.
Brine dosing pr. m3 of water.

Examples for dimension follow:
Example 1:
Water parameters:
Flow – 4,5 m3/h
Conductivity – 400 µS/cm
Chloride content – 75 mg/L
Hardness – 3 dH°
Organic material – 3 mg COD/L
Temperature – 25 °C
Pressure – 3 bar
Target free chlorine production – 1,5 ppm
Because of flow choose BT 180, at conductivity 400 µS/cm and chloride content 75 mg/L the system will
use 480 W*h/m3 to produce 6,26 ppm free chlorine. Target is 1,5 ppm free chlorine.
Power consumption – ( 1,5 ppm/6,25 ppm)*480=115 W*h/m3
Example 2:
Water parameters:
Flow – 2 m3/h
Conductivity – 600 µS/cm
Chloride content – 50 mg/L
Hardness – 8 dH°
Organic material – 8 mg COD/L
Temperature – 20 °C
Pressure – 2 bar
Target free chlorine production – 2,5 ppm
Because of flow choose BT 80, at conductivity 600 µS/cm and chloride content 50 mg/L the system will use
480 W*h/m3 to produce 3,24 ppm free chlorine. Target is 2,5 ppm free chlorine.
Power consumption – ( 2,5 ppm/3,24 ppm)*480=370 W*h/m3
BECAUSE OF HIGH dH° THIS SYSTEM HAS TO BE SUPPLIED WITH WATER SOFTENER. THE SOFTENER DOES
NOT AFFECT CONDUCTIVITY OR CHLORIDE CONTENT.
Example 3:
Water parameters:
Flow – 12 m3/h
Conductivity – 60 µS/cm
Chloride content – 5 mg/L
Hardness – 0,5 dH°
Organic material – 1 mg COD/L
Temperature – 20 °C
Pressure – 5 bar
Target free chlorine production – 2 ppm
Because of flow choose BT 180x3, at conductivity 60 µS/cm and chloride content 5 mg/L the system is out
of working parameters and we have to use a booster module.
If you choose to add 75 mg NaCl/l (300 mg brine/L) the conductivity will raise 165 µS/cm and chloride
content 44 mg/L.
New water parameters will be:
Conductivity – 60 µS/cm + 165 µS/cm = 225 µS/cm
Chloride content – 5 mg/L + 44 mg/L = 49 mg/L
BT 180x3 will use app. 480 W*h/m3 to produce 5 ppm free chlorine. Target is 2 ppm free chlorine.
Power consumption – ( 2 ppm/5 ppm)*480=192 W*h/m3
