تعد مشكلة شُح المياه العذبة من أهم العقبات التي تواجه استراتيجيات التطوير الزراعي و الصناعي عربياً و عالمياً، حيث يمتَّد وطننا العربي على مساحات واسعة جافة و شبه جافة، و يفتقر في معظمه إلى مصادر المياه العذبة، لذلك فقد أصبح اللجوء إلى خَيار إزالة ملوحة مياه البحر (التحلية) أمراً حتمياً لسد العجز المائي، خاصةً بوجود الشريط الساحلي الممتد على طول معظم البلدان العربية، فمياه البحر المحلاة تعد مصدراً متجدداً للمياه العذبة.
Fresh water shortage problem is the most important difficulty that counters agricultural and industrial
improvement strategies on both Arabic and international levels, where Arabian region extends along vast
arid and semi- arid areas, and mostly lacks for fresh water resources. Therefore, desalination choice has
become an inevitable option to compesate deficiency of water, especially with the long Arabian costal line,
where desalinated seawater is considered renewable fresh water resource.
However, desalination mechanism requires water pretreatment procedures in order to reduce total
hardness and pH values, to prevent salts precipitations which hinder thermal and membrane techniques.
