Dewan-20 T 1 kg
chlorine-free bath water treatment tablet
200 g tablet containing active oxygen for treating water in private pools with a volume of 3-50 m3. Can be used as a substitute for liquid, chlorine-free DEWAN® disinfectants, either on its own or to supplement their effect.
DOSAGE:
Preparation before dosing:
Before using DEWAN®-20, be sure to disinfect the entire water cycle of the pool! ("shocking").
Mix 0.5 kg/10 m3 of ALGA-SOKK P granules into the water, which has been previously dissolved in approx. 10 l of water. Circulate the water to mix the agent.
a) If the free active chlorine content of the pool water falls below 1 mg/l within 24 hours, the treatment must be repeated.
b) If the free active chlorine content of the pool water is above 1 mg/l after 24 hours:
- Wait until the free active chlorine content concentration drops to zero (1-2 days).
- Reduce the free active chlorine content to zero by adding the amount of NULLA-KLÓR calculated based on the measured free active chlorine content.
Initial dosage:
To quickly reach the initial concentration of DEWAN®-20 (active oxygen) (8 mg/l), place 2 DEWAN® -20 T tablets into the floating tablet dispenser and add 150 ml of ALGI-CID algae inhibitor per 10 m3 of pool water.
Continuous dosing:
To ensure the desired cleaning effect, the DEWAN-20 CONCENTRATION must be kept continuously close to 8 mg/l!
Ideally, 1 DEWAN®-20 T tablet per 10 m3 should be placed in the floating dispenser and 100 ml of ALGI-CID should be added to the pool. In practice, it may be preferable to dose based on the actual Dewan-20 (active oxygen) level.
To achieve the desired cleaning effect, the DEWAN-20 (active oxygen) level must be kept at around 8 mg/l at all times. If the measured value falls below 4.0 mg/l, add another DEWAN®-20 T tablet to the floating dispenser for every 10 m3.
MEASUREMENT:
During the first two weeks of operation, it is advisable to check the DEWAN®-20 concentration every two days:
- with a DEWAN®-20/pH tester or
- with a DEWAN®-20 measuring strip.
Two checks per week are also recommended thereafter.
