Solution

The correct answer is "all the above". Nanofiltration has several advantages, including:

  1. Reduced salt content and dissolved solid content (TDS) in brackish water: Nanofiltration is a membrane filtration-based method that uses nanometer sized through-pores that pass through the membrane. This process is used for the removal of hard divalent ions and salts from water, and is particularly effective in removing hardness (calcium and magnesium) from water.

  2. Reduced nitrates and sulphates: Nanofiltration is also effective in reducing the concentration of nitrates and sulphates in water. This is particularly useful in areas where the water supply is contaminated with these substances.

  3. Reduction in heavy metals: Heavy metals can be harmful to human health, and nanofiltration is an effective way to reduce the concentration of these substances in water.

So, all the mentioned advantages are true for nanofiltr

Which of the following statements is incorrect? Porous membrane contains fixed pores, in the range of 0.1-10 µm for microfiltration and 2- 100 µm for ultrafiltration. Porous membrane contains variable pores, in the range of 0.1-100 µm for microfiltration and 2- 100 µm for ultrafiltration. The main problem in microfiltration and ultrafiltration membrane is flux decline.
