I applied via Campus Placement and was interviewed before Jan 2022. There were 2 interview rounds.
Cation exchange is done first in ion exchange because cations are more easily exchanged than anions.
Cations have a higher affinity for the exchange resin than anions.
Cations are generally smaller in size and have a higher charge density, making them more easily exchanged.
Anions are larger and have a lower charge density, making them less easily exchanged.
Cation exchange is often used to remove heavy metal cations from ...
Pump curve shows the relationship between flow rate, pressure, and power. Mechanical energy is converted to hydraulic energy.
Pump curve is a graph that shows the performance of a pump at different flow rates and pressures.
It helps in selecting the right pump for a specific application.
The curve shows the relationship between flow rate, pressure, and power consumption.
Mechanical energy from the motor is converted to hyd...

Distillation is a process of separating components of a mixture based on their boiling points.
It involves heating the mixture to vaporize the more volatile component
The vapor is then condensed and collected as a separate liquid
Commonly used in the production of alcoholic beverages, fuels, and chemicals
Distillation is a process used to separate components of a mixture based on their boiling points.
Used in petroleum refining to separate crude oil into different fractions
Used in the production of alcoholic beverages to separate ethanol from water
Used in the chemical industry to purify solvents and separate different chemicals
Can be used in the purification of water
Can be used in the separation of air into its component
Heat exchangers are devices used to transfer heat between two or more fluids.
Shell and tube heat exchangers
Plate heat exchangers
Double pipe heat exchangers
Spiral heat exchangers
Air-cooled heat exchangers
Bubble point and dew point are two important concepts in thermodynamics used to describe the behavior of a mixture of liquids and gases.
Bubble point is the temperature at which a liquid mixture starts to boil and form bubbles of vapor.
Dew point is the temperature at which a vapor mixture starts to condense and form droplets of liquid.
Bubble point and dew point are related to each other through the vapor-liquid equilibr...
Chemical and Biological Oxygen Demand are measures of water quality and indicate the amount of oxygen required to break down organic matter.
Chemical Oxygen Demand (COD) measures the amount of oxygen required to oxidize organic and inorganic matter in water.
Biological Oxygen Demand (BOD) measures the amount of oxygen required by microorganisms to break down organic matter in water.
COD is a faster test and measures both ...
I applied via Company Website and was interviewed before Jan 2021. There were 3 interview rounds.
Pumps and aerators are used to move fluids and gases respectively.
Pumps work by creating a pressure difference to move fluids from one place to another.
Aerators introduce air into liquids to increase oxygen levels and promote biological processes.
Types of pumps include centrifugal, positive displacement, and jet pumps.
Types of aerators include surface aerators, diffused aerators, and mechanical aerators.

A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure.
Pressure vessels are used in various industries such as oil and gas, chemical, pharmaceutical, and food processing.
They are designed to withstand high pressures and are typically cylindrical or spherical in shape.
Examples include boilers, storage tanks, and compressed air tanks.
Designing a shell involves considering factors like material, shape, size, and functionality.
Consider the material of the shell - metal, plastic, or composite
Determine the shape of the shell based on the intended use - cylindrical, spherical, conical, etc.
Decide on the size of the shell to accommodate the contents it will hold
Design the shell with the necessary functionality in mind - openings, closures, ventilation, e
