Reason can be
1. Ignorance / poor hydrotest during commissioning.
2. Improper coating if the structure is in contact with harsh chemicals. (protect by use of Venyl Ester / FRP coating)
3. If the plant is constructed in seismic zone and not keeping in mind of the earth activities.
4. If any modification or maintenance activities involving puncturing of concrete then it may create problem at later stage.
high content of alkaline or acids and the presence of bacteria in the water of waste water plant can lead to loss of concrete compression strength and concrete disintegration , it also can lead to the corrosion of the reinforcement metal re bars usually water that has a PH value of greater than 6 can be used in the concrete mix but , a ph balance is not conclusive to gauge the water acid content .
therefore a more conclusive test that gauge the totality of the acidic contamination must be conducted .
complex attack from outside (..........) and inside(.................................) the system
السلام عليكم من الأسباب الجذرية للتدهور الخرسانة في محطات تحلية المياه هي اللسباب التي ذكروها وكذلك انواع من البكتيريا التي لها القدرة العيش في وسط مالح
Because waste water tends to break the microstructure of the concrete biolologically.
