Jain University Interview Questions and Answers

Environment compliances in industries include following regulations and guidelines to minimize impact on environment.

• Obtaining necessary permits and licenses for operations

• Implementing pollution control measures

• Proper waste management and disposal practices

• Regular monitoring and reporting of emissions and effluents

• Compliance with environmental laws and regulations

• Implementing sustainable practices to reduce environmental impact

Basis treatment techniques for wastewater COD include biological treatment, chemical treatment, and physical treatment.

• Biological treatment involves using microorganisms to break down organic matter in the wastewater.

• Chemical treatment involves adding chemicals to the wastewater to facilitate the removal of COD.

• Physical treatment methods include processes like filtration, sedimentation, and adsorption to reduce COD levels.

• Combination of these techniques is often used for effe...read more

ZLD parameters as per PPCB include TDS, pH, BOD, COD, and heavy metals.

• Total Dissolved Solids (TDS) should be reduced to minimum levels.

• pH should be within the permissible range set by PPCB.

• Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) levels should be minimized.

• Heavy metals such as lead, mercury, and chromium should be effectively removed.

• Effluent should meet the standards set by Punjab Pollution Control Board (PPCB).

Troubleshooting in Bio ETP involves identifying and resolving issues in the biological effluent treatment process.

• Monitor key parameters such as pH, temperature, dissolved oxygen levels, and organic load regularly.

• Check for any signs of foaming, odors, or unusual color in the treated water, which may indicate problems with the microbial population.

• Inspect mechanical components such as pumps, aerators, and mixers for proper functioning and maintenance.

• Perform regular sludge ma...read more

Parmates in outlet in ETP are microorganisms that help in breaking down organic matter in the effluent treatment plant.

• Parmates are essential for the biological treatment process in ETPs.

• They help in breaking down organic pollutants into simpler, less harmful substances.

• Examples of parmates include bacteria, fungi, and algae.

• Proper maintenance of parmates is crucial for the efficient functioning of ETPs.

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 is a water treatment process that uses pressure to force water through a membrane, removing impurities.

• It is commonly used in desalination plants to turn seawater into drinking water.

• Reverse osmosis systems are also used in households to purify drinking water by removing contaminants.

• The process is effecti...read more

ZLD stands for Zero Liquid Discharge and CTO stands for Consent to Operate.

• ZLD is a water treatment process where all wastewater is purified and recycled, leaving zero discharge at the end.

• CTO is a document issued by pollution control boards to industries allowing them to operate after meeting certain environmental standards.

• Both ZLD and CTO are important in ensuring environmental sustainability and compliance with regulations.
