Comeniusproject: waterworks How does a waterworks work? 1. Water is collected →natural water 2. Coagulant is added →organic substances are bonded 3. Filtration with quartz sand →the flocks are separated
Comeniusproject: waterworks 4. Deacidification with calcium carbonate →raise pH 5. Water is fumigated →last tertiary treatment 6.Water is collected →pure water 7. Water is drinkable
