Reverse Osmosis & Water Treatment in Angola

water-treatment-angola.jpg

Angola is a nation of eighteen million people in south-central Africa that fronts the South Atlantic Ocean, between Namibia and Democratic Republic of the Congo

Despite significant revenue from oil and diamonds, Angola is one of the poorest nations in the world, with a life expectancy of just 39 years and low rankings in most aspects of human development (Its Human Development Index is 146th of 169 nations).

Angola's major environmental issues include:

  • Overuse of pastures and subsequent soil erosion attributable to population pressures
  • Desertification
  • Deforestation of tropical rain forest, in response to both international demand for tropical timber and to domestic use as fuel, resulting in loss of biodiversity
  • Soil erosion contributing to water pollution and siltation of rivers and dams
  • Inadequate supplies of potable water

Water Resources

Total Renewable Water Resources: 184 cu km (1987)

Freshwater Withdrawal: Total: 0.35 cu km/yr (23% domestic, 17% industrial, 60% agricultural). Per capita: 22 cu m/yr (2000)

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 Angola’s water resources.


Angola’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 SystemsDesalination 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 FiltersChemical Dosing, UV Sterilizers.
  • Government water supply, which could have high level of hardness or high level of chlorine, can be treated with Water SoftenersMedia Water Filters

Water challenges in Angola
The Angolan government is redirecting its focus in the water treatment sector to address the shortage of water resources, and government provided water for its residents. The challenges that occupy the Angolan water sector mainly consists of: 

  • Progressive shiftment from an unregulated, concentrated public management systems towards a dispersed, public and private management system with strict regulation 
  • Advancement of financial security for the sector, guaranteeing entry to resources and services at a cost that is affordable to the public
  • Decreasing reliance on the government for investments in the water and sanitation industry
  • Suppliance of fresh, potable water and sewerage access for the entire population in correspondence to the development objectives established 
  • Mandatory water quality of the highest order, including efficient sanitation sector operators

Their solutions have been based on the establishment of water purification systems to achieving technical expertise through training government officials on national and municipal levels in the water sanitation industry

Seawater Desalination & Industrial Reverse Osmosis Systems
As droughts become more of a common occurrence, more regions throughout the world are turning to seawater desalination to meet their water objectives. Desalination seawater is a much more costly method of water purification than extracting water from other sources such as rivers, brackish water, water recycling, and water conversation. However, in many parts of the world, seawater desalination is the only option. Reverse osmosis systems are effective and more economical water treatment options, but come with a number of maintenance issues. The RO process includes ionic contamination from magnesium and calcium, organic substances, bacteria, viruses, scaling and insoluble particles.

Pure Aqua manufactures water treatment systems that meet the World Health Organization requirements.
