Vattenförsörjning i Serbien – intryck från ett studiebesök

During the spring of 2019, I had the opportunity to visit two waterworks in northern Serbia, in Subotica and in Novi Sad. In the latter city, I was also given the opportunity to meet researchers at the University. Serbia is one of the Balkan countries affected by high levels of naturally occurring arsenic, which in combination with high NOM levels is a major challenge to deal with in the waterworks. Subotica’s water plant has favorable conditions with lower NOM levels, which means that it is possible to reduce the permissible arsenic levels in the drinking water through ordinary sorption. In Novi Sad, you have other challenges with chemical pollution in the raw water, but here they had installed a relatively new development step with advanced purification technology.
