Containerised Brackish Water Desalination Units


The Water, Sanitation and Education Centre of Unicef Copenhagen partnered with Moerk Water to provide two brackish water Reverse Osmosis units to communities in need in in Eastern Ethiopia. The main sources of water in these communities were a combination of rainwater harvesting and contaminated, brackish wells. The wells are high in fluoride, microbiological contamination and can have salt levels up to 25 g/L. Moerk Water designed and constructed two automated, easy to use membrane filtration units, one with a capacity of 40,000 L/day and the other with a capacity of 80,000 L/day. The units are both equipped with energy recovery devices to reduce the total energy demand of the desalination process. The units operate with automated flushing sequences to ensure longevity of operation and are designed to be easy to use. Local technicians installed the units with hotline support to Moerk Water engineers and access to Moerk Water’s local service partner.


Project Outcomes:


  • Total capacity of units is 10,000 L/hr with units operational 12 hours per day. Total combined daily capacity is 120,000 L/day.
  • Units dispatched in mid-2019
  • Units installed by local technicians with hotline support to Moerk Water Engineers and access to Moerk Water’s local service partners
  • Units are capable of being operated using renewable energy
  • Capability Community Water Independence
