10+ Wabtec Interview Questions and Answers

The membrane Mak is a measure of the membrane's ability to remove contaminants from water in a reverse osmosis plant.

• Membrane Mak refers to the membrane's efficiency in removing impurities from water.

• It is a measure of the membrane's rejection rate for different contaminants.

• Higher Mak values indicate better performance of the membrane.

• Mak is typically expressed as a percentage.

• For example, a membrane with a Mak of 98% means it can remove 98% of contaminants from the water.

MGF stands for Mixed Growth Factor.

• MGF is a term commonly used in the field of biotechnology and cell culture.

• It refers to a mixture of growth factors that are used to stimulate cell growth and proliferation.

• These growth factors can include proteins, hormones, and other signaling molecules.

• MGF is often used in research and in the production of therapeutic proteins and vaccines.

• Examples of commonly used MGFs include epidermal growth factor (EGF), fibroblast growth factor (FGF)...read more

Backwash is the process of reversing the flow of water through a filter to clean and remove accumulated debris.

• Backwash is a common operation in water treatment plants and filtration systems.

• It helps to remove trapped particles, dirt, and impurities from the filter media.

• During backwashing, water flows in the opposite direction, dislodging and flushing out the accumulated contaminants.

• The backwash water is usually discharged to a drain or a separate treatment process.

• Backwash...read more

ACF stands for Activated Carbon Filter.

• ACF is a type of water treatment filter used to remove impurities and contaminants from water.

• It uses activated carbon, which has a high surface area and adsorptive properties, to trap and remove pollutants.

• ACF is commonly used in reverse osmosis (RO) plants to improve water quality before the RO process.

• It can effectively remove chlorine, organic compounds, and certain heavy metals from water.

• ACF needs periodic maintenance, such as carb...read more

The pH of RO water is typically slightly acidic, ranging from 5.5 to 7.0.

• RO water has a lower pH compared to tap water

• The pH of RO water can vary depending on the source water and the efficiency of the RO system

• Maintaining the pH of RO water within the acceptable range is important for various applications such as drinking water and industrial processes

RO water conductivity is a measure of its ability to conduct an electric current and indicates the level of impurities present.

• RO water conductivity is measured in microsiemens per centimeter (µS/cm).

• Lower conductivity indicates purer water with fewer dissolved solids.

• Higher conductivity suggests the presence of impurities such as salts, minerals, or organic matter.

• Monitoring RO water conductivity helps ensure the effectiveness of the reverse osmosis process.

• Regular testing a...read more

Antiscalet is used to prevent the formation of scale in RO plants.

• Antiscalet is a chemical additive used in reverse osmosis (RO) plants.

• It helps to prevent the formation of scale on the RO membranes.

• Scale is a buildup of mineral deposits that can reduce the efficiency of the RO system.

• Antiscalet works by inhibiting the crystallization of minerals, such as calcium and magnesium, that can form scale.

• By using antiscalet, the lifespan of the RO membranes can be extended and the o...read more

Suspended particles can be removed through various methods.

• Sedimentation - allowing particles to settle at the bottom of a container

• Filtration - passing water through a filter media to trap particles

• Coagulation - adding chemicals to clump particles together for easier removal

• Flocculation - gently stirring water to encourage particles to clump together

• Ultrafiltration - using a membrane to physically block particles from passing through

RO water hardness refers to the concentration of minerals in the water, which can affect the efficiency and lifespan of the RO plant.

• Water hardness is typically measured in terms of calcium carbonate (CaCO3) concentration.

• High water hardness can lead to scaling and fouling of RO membranes, reducing their performance.

• Water softening techniques like ion exchange or chemical dosing can be used to reduce water hardness.

• Monitoring and controlling water hardness is important for ma...read more
