Municipal water services continually utilize improved technologies so that they can offer their customers higher water quality. Water can be improved by partially softening the water, which results in lower detergent consumption and lower scaling on kitchen utensils and water fittings.
Successful trials by the municipal water services in Bad Driburg, Germany supported planning and designing the new German water plant in Alhausen with membrane treatment to soften the water.
This system was designed with nanofiltration membranes which provide water treatment without the use of chemicals. This is a big improvement over other softener techniques which require chemical injection.
