   Generally , only high salinity –Tolerant plants can be irrigated with concentrate of salinity higher than 2000mg/l.  Such plants  can not only tolerate high salinity but  also extract salt from the water and store it in its tissue or leaves.

  First of all, it is to be   ascertained whether there is a need for irrigation of water  for salinity tolerant vegetation nearby the site . It would be cost effective only if concentrate is blended with fresh water source or waste water to reduce its salinity to  levels acceptable for irrigation.

   There are plants can be grown using concentrate having  salinity  more than 2000mg/l ( In Middle East etc) .

 It also depends on site specific soil  conditions, effect on soil due to  the presence of Trace metals in the concentrate and its Toxicity if any caused by specific ion , and the impact on the  Ground water quality etc

 It needs a thorough  site specific study before taking a call.
