Purification of water in the Aral Sea regions Uzbekistan

The Republic of Uzbekistan is situated in Central Asia formerly part of Soviet Union. Uzbekistan is the most populated country in Central Asia and the population of the country is 27. 7 million people (July 2007 1) and the area is 447,400 km2.Decreasing of water sources in the Aral Sea basin has brought many problems and one other main problem is appearing of sewage water. Water which used from cleaning technology practically is not clean from oil and other damages. It does not give an opportunity of recycling water for secondary use in the Aral Sea area. In lack of water resources, secondary use of water may significantly decline water consumption for technical purposes. From another side, sewage water is also the main reason of living environment pollution, because it contains vestige of mineralization and biocides. Each year, wind whips 45 million metric tons of salty and contaminated dust into the air, contributing to health problems such as respiratory infections, tuberculosis, anemia, kidney diseases, diarrhea and cancer. This massive environmental disaster affects about five million people in the Central Asia. (As we know, the Aral Sea is situated in the middle of Uzbekistan and Kazakhstan). From 2004, Czech Republic with cooperation PROTE firm has been realizing development project under the title of Improvement of the quality of drinking and irrigation water in the Aral Sea region by clearing equipment and sorbents produced in the Czech Republic in the Autonomic Republic of Karakalpakstan, Uzbekistan. This work is the study of possibilities of water purification technologies infrastructure in the selected regions in Uzbekistan for improving water management systems and preventing it from living environment pollution, including installation of water purification equipments in the Aral Sea area.
