Reverse Osmosis & Water Treatment in Afghanistan
Afghanistan (33°00' North, 65°00' East) is a landlocked country in central Asia with a total area of about 652,000 square kilometers (km2). It is bordered by Turkmenistan, Uzbekistan, and Tajikistan to the north, China to the northeast, Pakistan to the east and south, and Iran to the west. It is characterized by its rugged terrain and an average elevation of 1,100 meters (m) above sea level, ranging from 150 to 8,000 meters. About three-quarters of the territory consist of mountains and hills, while lowlands include river valleys in the northern part, and desert regions in the southern and southeastern part.
Based on the hydrographic systems, the country can be divided into four zones:
- The northern basin (24% of the territory) with the Amu Darya and its tributaries (14%), which drain towards the Aral sea, and the rivers of northern Afghanistan (10%), which disappear within the country before joining the Amu Darya;
- The western region (12%) consisting of the Hari Rud river basin (6%) and the Murgab river basin (6%), both rivers disappearing in Turkmenistan;
- The southwestern basin (52%) with the Helmand river flowing towards the Sistan swamps, located on the border of Iran and Afghanistan. In 1972, a document was signed between Afghanistan and Iran to allocate a discharge of 26 meters per second (m/s) of Helmand river water to Iran all year round;
- The eastern Kabul basin (12%), which is the only river system having an outlet to the sea, joining the Indus at Attock in Pakistan.
Internal renewable water resources are estimated at 55 cubic kilometers per year (km3/year). The Kunar river, which originates in Pakistan, crosses the border with an average annual flow of 10 km3 and joins the Kabul river at Jalalabad about 180 km further downstream. The Kabul river flows again into Pakistan 80 km further downstream.
Total water withdrawal was estimated at 26.11 km3 in 1987, of which 99% was consumed for agricultural purposes. Recently, there has been a large development of groundwater use in some provinces.
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 Afghanistan’s water resources.
Afghanistan’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.
