Sandfilters - Veetehnoloogia OÜ

Because it is difficult to find another equivalent water treatment device in terms of reliability and efficiency. This is confirmed by 18 years of experience and customer satisfaction. Unlike many other filters available in Estonia, the pair pressure filters are fully compliant with the drinking water treatment standard “EVS 847-2: 2016. Water supply. Part 2: Water Treatment 'Requirements. Fully automatic pair pressure filters can be characterized as follows:

• Compact, robust and corrosion-resistant design

• Fully automatic water treatment

• High reliability, low maintenance and low operating costs

• Water treatment is environmentally friendly and user friendly, without the use of chemical reagents

• Filters are cleaned with purified water only, not raw water, like most single pressure filters, which ensures long life and trouble-free operation on the filter

• There is no need for a wash water collection tank and a washing pump

• Clean the water supply to the water while the filters are flushed

• The high oxygen content of purified water gives fresh water a fresh flavor and contributes to the inhibition of corrosion in the urban water network.

The oil-free compressor supplied with the pressure filter gives compressed air to the water for aeration and for the operation of the pneumatic actuators with filters. For larger filters, air to water will also be flushed. The pair pressure filters are only washed with purified water.

So far, the experience of operating fully automatic pair pressure filters installed by us has shown that iron and manganese content of purified water, as well as other quality parameters that affect the organoleptic characteristics of water and characterize general pollution, meet the requirements for drinking water in Estonia.

Thanks to the intensive aeration, the water supplied to the water network has enough dissolved oxygen to give the water a fresh and pleasant taste.

The high oxygen content of the water (O₂> 3.0 mg / l) creates the prerequisites for the elimination of the undesirable anaerobic environment in the water pipelines and the inhibition of corrosion in the water network.

You need to know before asking for a quote

• Borehole pump performance (raw water flow), l / min or m3 / h (measured with a water meter in a borehole header while deep water pump is running)

• Water consumption data (max m3 / h, m3 / d or m3 / month)

• Data from chemical analysis of groundwater pumped from the borehole "Drinking water quality indicators table“

• After the water treatment, is the water fed directly into the water network or collected into a clean water tank?
