Experienced water treatment contractor

Malmberg waste water treatment plant

We build water- and waste water treatment plants and we take you through the entire project from design to commissioning with focus on sustainability and efficiency. Malmberg was one of the first companies already in the 1940s that was part of the Swedish water infrastructure build up. Today we commission treatment projects for water demanding industries and for local water authorithies around the world.

Take a look at some of the treatment plants we have built

Water treatment plant in Klaipeda, Lithuania

Malmberg Klaipeda WT

Water treatment process and equipment delivered in partnership with the German company Chriwa. The plant is one of Europe’s most modern and advanced treatment plants today.

Klaipeda had problems with ammonium and fluoride in its raw water for a long time. Separating these substances called for an advanced process technology with flocculation and sand filtering, biological filters for nitrification and reversed osmosis (RO) to remove fluoride.

The capacity of the water treatment plant is 21,600 m3/d which supplies clean water to Klaipeda’s 180,000 inhabitants.
