A water treatment plant is a facility that processes raw water to make it safe for drinking, industrial use, and other purposes.

• Removes impurities and contaminants from raw water

• Uses processes like coagulation, filtration, and disinfection

• Produces clean, safe water for consumption and other uses

WTP stands for Water Treatment Plant, which is a facility where water is treated to make it safe for consumption or other uses.

• WTP is responsible for removing impurities and contaminants from water sources.

• Processes at WTP may include filtration, disinfection, and chemical treatment.

• WTP ensures that water meets regulatory standards for safe consumption.

• Examples of WTPs include municipal water treatment plants, industrial water treatment facilities, and desalination plants.

Ro stands for Reverse Osmosis, a water treatment process that uses a partially permeable membrane to remove ions, molecules, and larger particles from drinking water.

• Reverse Osmosis is a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from water.

• It is commonly used in water treatment plants to produce clean drinking water.

• Reverse Osmosis can remove contaminants such as lead, sodium, and other impurities from wat...read more

Gears are mechanical components that transmit power and motion between rotating shafts.

• Spur gears

• Helical gears

• Bevel gears

• Worm gears

• Planetary gears

Coagulation is the process of adding chemicals to water to make particles clump together for easier removal.

• Coagulation is the first step in the water treatment process.

• Chemicals like alum or ferric chloride are added to water to neutralize charges on particles.

• Neutralized particles then stick together to form larger clumps called flocs.

• Flocs are easier to remove through settling or filtration processes.
