Good Nice information

[@yunisaabidi7763]

Is there any difference between SDI test and turbidity test.

[@industriallearningswithabu1388]

Yes, there is a difference. The SDI (Silt Density Index) test measures the fouling potential of water by forcing it through a filter and is specifically used to predict the fouling of reverse osmosis membranes On the other hand, a "turbidity test" measures the cloudiness of water caused by suspended solids. While both relate to particles in water, they assess different characteristics and are not directly correlated.

[@industriallearningswithabu1388]

SDI (Silt Density Index)** measures the fouling potential of suspended solids, while **turbidity** measures the actual amount of suspended solids. They are not the same and do not directly correlate.
**For example, you think i can lift 100 kg weight
(you have the potential)
and a machine has lifted a quantity of weight, which shows how much it is.
(Just example to understand)**

Thanks, one more question please, how I can remove calcium sulphate scales from the system.

[@industriallearningswithabu1388]

Of course, by chemical cleaning :
• Acid cleaning: Use of acidic cleaning solutions, such as citric acid or hydrochloric acid, to dissolve calcium sulfate scales. The acid solution is circulated through the RO system for a specified period to dissolve the scales effectively.
• Alkaline cleaning: Utilization of alkaline solutions, such as sodium hydroxide, to solubilize and remove calcium sulfate scales.
