Sulphate, chloride, and fluorideadd
The content of sulphate, chloride, and fluoride in drinking water can be reduced by nanofiltration.
Nanofiltration is applied to purposively reduce unwanted components in full or in part. Nanofiltration applies a pressure typically under seven bar, resulting in lower energy consumption.
Nanofiltration is a membrane technology, which in its mode of operation and construction is very similar to reverse osmosis. A nanofiltration membrane primarily restrains divalent ions and larger molecules.
NYE ('new'), a new suburb in Aarhus, Denmark, is a waterwise suburb in which 40 % of the water consumption is covered by rain water harvesting.
EUROWATER has developed and established the water treatment solution with ultrafiltration, to treat the rain water and reuse it for toilet flushing and washing machines. This radical urban development project is a close coopration between consultants, private developer and local water utility.
Pressure filters from EUROWATER are designed to use only a natural process such as oxidation and filtration for producing drinking water. Good work environment and no wastewater problems are some of the benefits of the EUROWATER way.
Safety, reliable operation and automation describes a modern water treatment solution.

Analyzer for online measurement of turbidity, oxygen and temperature. Helps maintain a reliable operation and ensure pure drinking water.
The aeration equipment consists of a compressor unit and control air system.
Oxydation and filtration take place in a pressure filter plant where the water is aerated in order to supply a sufficient oxygen content to the water so that the present quality requirements are met. Two pressure filters can function as two independent production lines or in series.
After the oxydation and filtration, the drinking water is stored in a clean water tank before it is distributed to the consumer.
The substances which are detained in the filter are removed at the backwash. Periodic rinsings at which frequency, intensity, and duration are laid down as needed.
The distribution takes places by the means of a frequency-controlled pumping plant.
UV disinfection can efficiently reduce microbiological growth in water. This ensures safe and clean drinking water.
The entire process is controlled, regulated, and monitored centrally from an automatic control system (SRO/PLC).
Drinking water production require a number of technologies depending on the composition of the raw water.
We have selected three of the most common technologies for production of pure drinking water.
High quality drinking water is vital and UV disinfection is an extra security measure to ensure clean drinking water by eliminating the risk of microbiological contamination.
In many countries, drinking water is disinfected by adding chlorine. It is important to remove free chlorine to ensure clean drinking water. Activated carbon can also be used for removal of pesticides which can be found in groundwater.
A EUROWATER pressure filter is a safe and chemical-free solution to attain clean drinking water by removing iron, manganese, ammonium, and aggressivity.
