Reverse Osmosis & Water Treatment in Turkmenistan
Turkmenistan is a landlocked nation of five million people in central Asia, bordering the Caspian Sea, between Iran and Kazakhstan.
The western and central low-lying desolate portions of the country make up the great Garagum (Kara-Kum) desert, which occupies over 80% of the country. The eastern part is plateau.
Its major environmental issues include:
• Contamination of soil and groundwater with agricultural chemicals, pesticides
• Salination, water logging of soil due to poor irrigation methods
• Caspian Sea pollution
• Diversion of a large share of the flow of the Amu Darya into irrigation contributes to that river's inability to replenish the Aral Sea;
Total Renewable Water Resources: 60.9 cu km (1997)
Freshwater Withdrawal: 24.65 cu km/yr (2% domestic, 1% industrial, 98% agricultural)
Per Capita Freshwater Withdrawal: 5,104 cu m/yr (2000)
Access to improved sources of drinking water: 83% of population
Access to improved sanitation facilities: 98% of population
River Basins and Water Resources
The river runoff originating in the country is estimated at 1.0 cubic kilometers per year (km3/year). Several rivers are found in Turkmenistan, most of them flowing into the country from its neighbors.
The agreement among the five Central Asian republics stipulates that on average 22 km3/year are to be reserved for Turkmenistan (of which 0.68 km3/year are internal renewable water resources [IRWR]) and 22 km3/year for Uzbekistan. It has been considered that the latter comes into Turkmenistan before being used downstream in Uzbekistan.
During the Soviet period, water resources sharing among the five Central Asian republics was on the basis of master plans for water resources development in the Amu Darya and Syr Darya basins. In 1992, with the establishment of the Interstate Commission for Water Coordination, the newly independent republics agreed (February 18, 1992) to prepare a regional water strategy, and to continue to respect the existing principles until the adoption of a new water sharing agreement to be proposed by this new water strategy.
Non-conventional Sources of Water
The volume of treated industrial and domestic wastewater is estimated at 0.025 km3/year. For the period 1990-94, agricultural drainage water was estimated at about 5.4 km3/year on average. Water from both sources is mixed in the collector-drainage canals. About 2.35 km3/year, or 44% of the total, return to rivers, mainly the Amu Darya River. About 2.97 km3/year, or 55% of the total, goes to natural depressions, mainly Lake Sarakamysh in the north of the country on the border with Uzbekistan. The remainder, about 0.08 km3/year (1% of the total), is directly re-used for irrigation.
Lakes and Dams
There are 18 artificial reservoirs with a total capacity of about 2.89 km3: 8 on the Murghab River; 3 on the Tedzhen River; 3 on the Atrek River; and 4 on the Kara Kum Canal. The largest reservoir is the Hauz-Khan Reservoir on the Kara Kum Canal with a total capacity of 0.875 km3. All the reservoirs were been designed and constructed mainly for irrigation purposes, and are affected by heavy siltation.
The gross hydropower potential of the country is estimated at 5.8 gigawatt hours (GWh), while the total installed capacity was about 0.7 GWh in 1993. The construction of the Puli Hatum reservoir on the Tedzhen River on the border between Iran and Turkmenistan has been planned but is awaiting agreement between the two countries. Its total capacity would be 1.3 km3, and it has been designed for flood control, hydropower generation, and flow regulation purposes.
The outflow of drainage water has led to the creation of artificial lakes in natural depressions. The largest one is Lake Sarakamysh with a storage capacity of about 8 km3. A major environmental issue in Turkmenistan is the permanent accumulation of pollutant salt in these lakes, as this leads to the degradation of their flora and fauna.
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 Turkmenistan's water resources.
Turkmenistan's main water resources are:
Surface water “is water from river, 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.
