Turbidity is a measure of the amount of tiny particles in water, also known as the concentration of suspended matter in water. These tiny particles can be solid particles suspended in water, organic matter, air bubbles, etc. Turbidity is determined by measuring how much light is scattered and absorbed in water and is expressed as a numerical value or in relative units (e.g. NTU) Turbidity is measured in NTU: Nephelometric Turbidity Units.

Inter Discipline Check (IDC) is an activity done by Design Engineers in Plant Design Companies. IDC is performed to ensure that the design and engineering output including supplier documentation is meeting the project design requirements by all related internal disciplines.

The optimal pH for drinking water is typically between 6.5 and 8.5. To adjust the pH, you can use pH drops or tablets to neutralize acidic water or add a few drops of lemon juice to lower the pH of alkaline water. For a more permanent solution, installing a water filtration system that adjusts pH is an option But in plants, we use hydrated lime or caustic soda to increase pH and sulphuric acid to decrease the pH.

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.

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.

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.

Yas please

Thank you, sir, for your appreciation.
