environmental impacts of desalination

Published on by

Reading so much these days about desalination and other technologies used for filtering water. Can expert tell me what are the environmental impacts of desalination? Or there is no bad value associated with desalination? Curious to know.

  1. Desalination impacts on the environment, turn the lands into desert, no tree will grow up to one meter. All tree will be less than a meter. Also the grass will grow scatted, not cow will found in that area.  

  2. Dear Supriya,

     

    Almost all the projects have impacts on the environment, with proper mitigation measure impacts can be controlled and minimized. Based on the scale of the project impacts are classified into severe and moderate/permanent and temporary. Hence there are CRZ laws enacted by MoEF.

    Coming to desalination plant, it impacts are there on the marine ecology. As the water will be pumped to the treatment plant, some area around the plant will have severe and permanent impact to the organisms of the marine ecosystem.

     

    EIA report of the desalination plant will give more information.

  3. Desalination usually requires large amounts of energy, thus releasing large amounts of CO2 into the atmosphere. Also, the impurities and the salts removed from the water are usually dumped back into the ocean/sea, increasing the waters salinity, which has adverse affects on the surrounding environment and aquatic life.

    I hope this helps.

  4. As far as any technology is concerned, there would be some adverse impact on nature. But considering the water need and thirst we have to make sure that Environmental Impact of any project is done by regulators for any technology plant prior to construction. In the case of desalination, some impact would be there on Aquatic life. But the regulators do a proper study for minimizing the adverse effect on environment.
