Menengok Cara Penjernihan Air PDAM (Pengolahan Air PDAM) 7 pra 2 1 m1 1

Summary

The script outlines the water treatment process by PDAM, a regional company that transforms raw river water into consumable water. It begins with water intake, followed by various purification processes at the Water Treatment Plant (WTP), including coagulation, sedimentation, and filtration. The water is treated through gravity-based methods, chemical coagulants, and mechanical aids to separate impurities. The purified water is then stored and distributed to customers, ensuring a clean and safe water supply.

Takeaways

• 💧 PDAM (Perusahaan Daerah Air Minum) is a regionally-owned enterprise responsible for treating raw water from rivers to make it suitable for consumption.
• 🔧 The water intake process involves adjusting the volume of water to meet requirements by opening or closing gates.
• 🏭 Water treatment plants (WTP) are the main facilities where various processes occur to purify the water, including coagulation, sedimentation, and filtration.
• 🚰 Water is moved between different treatment processes using equipment such as water pumps or airlifts.
• 🔄 Each stage of the treatment process has its designated containment area for further processing.
• 📊 Automated control equipment is used to manage all processes within the water treatment facility.
• 🌀 The water purification process includes a simple sedimentation method where water from the river is first settled and then sent to a sedimentation tank.
• 🔬 The water goes through two stages of filtration using materials like gravel and sand or silica sand to remove finer impurities.
• 🧪 Advanced water purification techniques involve the use of chemical coagulants, such as alum, to help bind and settle impurities.
• 🔄 The coagulated water is then subjected to rapid and slow mixing to encourage particle collision and the formation of larger particles.
• 🏡 After the water is treated and filtered, it is stored in a clean water tank, ready to be pumped and distributed to homes for use.

Q & A

What does PDAM stand for and what is its role in water treatment?

PDAM stands for Perusahaan Daerah Air Minum, which is a regional water company responsible for treating raw water from rivers to make it suitable for consumption.

How is the volume of water intake regulated at the intake point?

The volume of water intake is regulated by adjusting the intake to ensure the water flow meets the required demand, typically by opening or closing gates.

What is the main location where water treatment processes occur?

The main location for water treatment processes is at the Water Treatment Plant (WTP), where various steps are carried out to purify the water.

What are some of the processes involved in water purification at the WTP?

Processes at the WTP include coagulation to separate dirty particles, the addition of purifying agents, sedimentation, and filtration to move water from one process to another.

What equipment is used to move water between different treatment stages?

Equipment such as motor-driven pumps or water pushers are used to move water between different stages of treatment.

How is the treated water stored before distribution?

The treated water is stored in a separate containment area before being distributed to customers.

What is the first step in the simple water purification process described in the script?

The first step is the collection of water from the river, which is then directed into a storage tank.

What materials are used in the first filtration tank to filter the water?

The first filtration tank uses layers of stone and sand, or possibly silica sand, to filter out larger impurities.

How does the second filtration tank improve the clarity of the water?

The second filtration tank uses finer materials, such as smaller stones and sand or silica sand, to filter out finer impurities, resulting in clearer water.

What is the purpose of adding coagulants like alum, PAC, and others in the water treatment process?

Coagulants are added to the water to help bind together fine particles and impurities, making them easier to settle or be filtered out.

What are the goals of the flocculation process in water treatment?

The flocculation process aims to break down the coagulated particles and impurities into simpler, well-dispersed parts within the water, facilitating their removal.

How does the sedimentation process contribute to water purification?

The sedimentation process allows the coagulant-bound impurities to settle at the bottom of the tank, leaving clearer water to be directed to the next stage of filtration.

What is the final step in the water treatment process before the water is distributed for use?

The final step is pumping the clean water from the storage tank and distributing it to homes for use.
