FE 500 and FE 500D are both types of steel used in construction, but they have different properties.

• FE 500 has a minimum yield strength of 500 N/mm², while FE 500D has a minimum yield strength of 500 N/mm² with higher elongation.

• FE 500D is more ductile and has better seismic resistance compared to FE 500.

• FE 500D is recommended for areas prone to earthquakes or seismic activities.

• FE 500D steel has a higher percentage of...read more

The process of a Water Treatment Plant (WTP) involves several stages to purify water for safe consumption.

• Coagulation and Flocculation: Chemicals are added to water to remove suspended particles.

• Sedimentation: The water is allowed to settle, and the solids are removed.

• Filtration: Water passes through various filters to remove smaller particles.

• Disinfection: Chlorine or other disinfectants are added to kill harmful micr...read more

The capacity of a Water Treatment Plant (WTP) is measured in million gallons per day (mgd).

• WTP capacity is the maximum amount of water that can be treated and supplied per day.

• It is an important factor in determining the water supply capability of a WTP.

• Capacity can vary depending on the size and design of the plant.

• For example, a WTP may have a capacity of 10 mgd, meaning it can treat and supply up to 10 million gallo...read more
