what we learn

• res desalination is technically feasible in
  some cases economical attractive
• special care on the intermittent operation of the
  desalination unit
• important parameters for the success of a RES
  desalination installation are
• - selection of the proper RES, Desalination
  technologies and their
• combination
• - system design and equipment selection
• - control system
• most of the applications are pilot plants

???? CRES

recommendations

• more RD work on the intermittent operation of
  the res desalination systems
• more work on small energy recovery systems
• strong effort on RD and manufacturers
  co-operation
• more installations budget consideration for the
  post-project period
• acceleration of education, training and
  information dissemination
