Technology for
clean drinking water
Safe Drinking Water is the cornerstone of public health
Climate change and extreme weather is challenging the water supply in most countries including Norway. Leachate and agricultural run-off is increasing humic acid and the organic content in surface water sources.
Sterner designs and constructs turn key solutions for drinking water treatment plants. With over 30 years experience Sterner has developed a robust and reliable solution in the AquaZone process. No external chemicals and very low emissions AquaZone ensures safe and hygienic drinking water.
Sterner also supplies high quality components including UV systems, filtration, pumps etc.

Disinfection and filtration
For decades, Sterner has supplied complete solutions for disinfection and filtration of water to municipalities, the aquaculture industry and food industry.
Sterner supplies UV of all types for water disinfection. Our project engineers will ensure the correct dimensioning of the correct approved UV system for your water treatment process. All UV systems are carefully tested and proven to deliver the correct dose. Complying to norms and standards, they are certified in accordance with both national and international legislation for drinking water. We also supply original components and spares, ensuring system function within current standards at all times.
Our filter solutions can be adapted for most applications including self flushing pressure filters, pressure-free drum filters or manual filtration. Contact us for a filter proposal.
Chemical free colour removal and disinfection
- First ozone is dosed to the water in a contact tank which is based upon the organic and colour content of the raw water. This breaks up the organics and colour into tiny fragments and actively oxygenates the water.
- Water is passed over a biological filter which removes the tiny fragments of colour and removes any components that may impair the taste of the water. This makes the water completely clear.
- Water is then disinfected over a UV system before being released onto the supply network.
