Some municipalities are lucky enough to be able to distribute untreated spring water. We recommend they go on taking great care of their source protection areas.
Many water sources are however contaminated with germs, and often have excessive turbidity. This type of problem is common for karstic springs, but it is also encountered in surface waters issuing from lakes and rivers, or in sources which are fed by surface water.
Ultrafiltration is the ideal technology for the treatment of this type of water, as it clarifies and disinfects in one single stage. Other water quality issues, such as excessive hardness or the presence of dissolved micropollutants (e.g. pesticides), can be solved with nanofiltration, reverse osmosis or otherwise by using hybrid treatments, such as ultrafiltration coupled with activated carbon.
