Variable water sources
Flexible customised solutions
Tap water
Drinking water from the public supply network is used as the starting point for many industrial and medical water treatment processes.
Surface water
Lakes, rivers and rainwater require a thorough treatment to remove particles, micro-organisms and dissolved substances.
Seawater
Desalination of seawater allows this source to be used for industrial and drinking water applications in regions where water is scarce.
