Generally all plants showed normal performance but the need to improve and increase their production rate without increasing their water resource abstraction HOAt necessary to meet the water demand of the Gaza Strip population. Recovery rate and TDS removal was made to evaluate all selected desalination plants' performance.

Dissolved inverse soluble mineral salts in cooling water such as calcium carbonate, calcium sulphates, calcium silicate, etc. often contribute to the formation of scales. Normally scale is developed from the accumulation of precipitation of mineral crystal salts from water on metallic surfaces. However, crystallisation fouling or scaling is caused by crystalline deposition from water-soluble salts. All these are essential factors which affect the water fouling rate . Deposition rate on metal surfaces is dependent on surface characteristics. Mineral fouling could be retarded by addition of additives. Most of the additives presently used are hazardous to the environment  and . So to explore ecofriendly additives it is also a prime objective of the present work.
