Dynamic Breakthrough in the World of Water Solutions

Zero Liquid Discharge has been evoking an ample interest due to the increasing need to manage the industrial water cycle. Quatar is in the forefront following this trend in the Middle East. According to the Quatar government, it is concerned about potential brine-related problems and supported by large oil and gas revenues, is looking to develop desalination methods including Zero Liquid Discharge. As is the case with other technologies, Zero Liquid Discharge too has its set of disadvantages. The desalination process produces two streams of clean water and brine water that needs be disposed. The university along with the Qatar Science & Technology Park are involved to launch a project that would remove salt from groundwater via Zero Liquid Discharge. This process is intented to remove the salt chemically via a lime-aluminium process. If the innitative results in success, the technology is said to be commercialized and exported.

The US’GE Water already backs the use of the Zero Liquid Discharge to produce salt for commercial purposes. The firm has developed a Zero Liquid Discharge sea water desalination system that produces fresh water and pure salt that is used to produce commercial-grade chlorine gas and caustic soda. As is said that as fresh water demand continues to grow and exceeds available supply water recovery and re-use using Zero Liquid Discharge will increase.

Quatar being in the front line that is encouraging state energy group Qatar Petroleum and its joint venture partners to install Zero Liquid Discharge in its new plant facilities. Zero Liquid Discharge has now been specified by Qatar Petroleum for all new industrial products.

Zero Liquid Discharge has already been in use at the shell-operated, gas-to-liquid (GTL) project. France’s Veolia Water Solutions and Technologies was selected to provide an environmentally sound water treatment complex to treat effluents from the plant with the highest efficiency of water rescue, resulting in no discharge of water. ZLD system was provided the evaporation and crystallisation process design for the ZLD system, which concentrates the effluent stream to a solid residue. The plant will rely on the water recovered from the system as a major portion of its overall water demand.

Aquatech has substantial expertise and experience in shale water, coal-to-liquid and produced water segments globally and would like to see itself as a first mover in these key technologically driven business segments in the near future.
