WTE INFRA PROJECTS Interview Questions and Answers

Desalination is the process of removing salt and other minerals from seawater to make it suitable for drinking or irrigation.

• Desalination can be done through processes like reverse osmosis, distillation, and electrodialysis.

• Reverse osmosis involves forcing seawater through a membrane to separate salt from water.

• Distillation involves heating seawater to create steam, which is then condensed back into water, leaving the ...read more

Reverse osmosis is a water purification process that uses a partially permeable membrane to remove ions, molecules, and larger particles from drinking water.

• Reverse osmosis works by applying pressure to a concentrated solution to force water molecules through a semipermeable membrane, leaving behind contaminants.

• The process helps remove impurities such as salt, minerals, and other particles from water, making it suitab...read more

A flow diagram of a desalination plant shows the process of converting saltwater into freshwater.

• Intake of seawater from the ocean

• Pre-treatment to remove large particles and debris

• Desalination process (such as reverse osmosis or distillation)

• Post-treatment to ensure water quality meets standards

• Distribution of freshwater to consumers

• Disposal of brine or concentrated salt solution

• Energy recovery systems to optimize effi

Type V cement is typically used in sulfate-rich water due to its high resistance to sulfate attack.

• Type V cement is specially formulated to resist sulfate attack

• It has a low heat of hydration and high resistance to chemical attack

• Examples of Type V cement include Portland cement and blended hydraulic cements

A pile is a long, slender column typically made of concrete or steel used to support structures like buildings or bridges.

• Piles are driven into the ground to transfer loads from the structure to the soil below.

• They are commonly used in construction projects where the soil is not strong enough to support the weight of the structure.

• Examples of where piles are used include building foundations, bridges, and retaining wal

Project life cycle is the series of phases a project goes through from initiation to closure.

• It includes initiation, planning, execution, monitoring and control, and closure phases.

• Initiation involves defining the project and its objectives.

• Planning involves creating a roadmap for the project, including timelines, budget, and resources.

• Execution involves carrying out the plan and completing the project deliverables.

• Mon...read more

Water and wastewater treatment plant erection and commissioning involves the installation and start-up of the necessary equipment and processes for treating water and wastewater.

• Erection and commissioning involves the installation of equipment such as pumps, pipes, tanks, and filters.

• The process includes setting up the necessary treatment processes like coagulation, flocculation, sedimentation, filtration, and disinfec...read more
