Sankei Pragati India Interview Questions and Answers

DP in RO stands for Design Pressure in Reverse Osmosis.

• DP is the pressure required to push water through a RO membrane.

• It is measured in pounds per square inch (PSI).

• The higher the DP, the more energy is required to operate the RO system.

• DP can be affected by factors such as membrane fouling and scaling.

• Monitoring and controlling DP is important for maintaining RO system efficiency and performance.

Conductivity increases with increasing TDS.

• Conductivity is a measure of a solution's ability to conduct electricity.

• TDS (total dissolved solids) refers to the amount of dissolved solids in a solution.

• As TDS increases, the number of ions in the solution increases, leading to higher conductivity.

• Conductivity can be used to estimate TDS levels in water.

• For example, seawater has a higher TDS and conductivity than freshwate
