Reverse Osmosis & Water Treatment in Estonia
Estonia, with a total area of 45,100 square kilometers (km2), is one of the three Baltic states. It is bordered in the north by the Gulf of Finland, in the east by the Russian Federation, in the south by Latvia and in the west by the Baltic Sea. Restoration of its independence from the Soviet Union took place in August 1991. The main administrative units are 15 counties, 209 municipalities, and 45 towns.
Estonia is situated on the southern slope of the Fennoscadian shield. The territory of Estonia rose from the sea bed and its surface is relatively flat with an average altitude of 50 meters (m) above sea level. The higher areas are the Haanja uplands in the southeast, with a peak of 318 m, and the Pandivere uplands in the northeast, with a peak of 166 m.
More than 1,500 islands in the Baltic Sea are part of Estonia, constituting 9% of the territory. There are over 1,400 lakes, covering over 6% of the total area of the country, and about 21% of the total area is swamp. The soils of Estonia are generally heavy and stony. The quaternary deposits are unevenly distributed, almost absent at the northern coast while being up to 200 m thick in the south.
Estonia can be divided into five hydrological basins: the Lake Peipus-Narva basin in the east; the Gulf of Finland basin in the north; the Gulf of Riga basin, including the Salaca River, in the southwest; the Muhu Sound basin, including the Gauja River, in the southeast; and the Islands.
Estonia is rich in groundwater resources. The internal renewable groundwater resources are estimated at 4 km3/year. The main recharge area is in the Pandivere uplands, where limestone areas and sand/gravel ridges are locally important. Generally, in southern Estonia the groundwater of the Devonian aquifer is used, while in western and sporadically in central Estonia the water of the Silurian-Ordovician horizon is used. Groundwater covers about two-thirds of the drinking water supply. Part of the groundwater flows out to the sea and part returns to the surface water system. This latter part, which is already accounted for in the runoff (overlap), has been estimated at 3 km3/year.
The World Bank reports that at least 80 countries have water shortages and 2 billion people lack access to clean water. More disturbingly, the World Health Organization has reported that 1 billion people lack enough water to simply meet their basic needs, unfortunately in many countries water is scarce or contaminated.
Pure Aqua provides wide range of filtration and economical solutions based on the Estonia’s water resources.
Estonia’s main water resources are:
- Surface water “is water from river, rain water, lake or fresh water wetland, which can be treated using different methods, such as Ultrafiltration Systems, Media Water Filters, Brackish Water RO.
- Desalination can be used for water from ocean, or sea source, which can be treated using Sea Water Reverse Osmosis Systems; Desalination Systems
- Ground Water or brackish water is from water located in the pore space of soil and rock “Borehole well”, which can be treated using Reverse Osmosis Systems, Media Water Filters, Chemical Dosing, UV Sterilizers.
- Government water supply, which could have high level of hardness or high level of chlorine, can be treated with Water Softeners, Media Water Filters
Pure Aqua manufactures water treatment systems that meet the World Health Organization requirements.
