Takeaways

• 😀 The speaker introduces a project about water purification created by students from Bengkulu, Indonesia.
• 😀 The project aims to participate in a national scientific writing competition held by the Ministry of Public Works and Housing in 2020.
• 😀 The project explains the process of purifying river water that contains microorganisms and contaminants.
• 😀 A filtration system consisting of four stages is used to purify the water, including gravel, biochar, and active charcoal.
• 😀 The first stage filters the water with gravel to help oxygenate the water through an aerobic process.
• 😀 The second stage uses biochar to absorb manganese and remove yellow color from the water.
• 😀 The third stage filters the water using living materials to eliminate coarse contaminants.
• 😀 The fourth stage utilizes active charcoal to eliminate bad odors, color, and organic compounds from the water.
• 😀 After the water is filtered, it enters a final filtration stage and passes through several types of filters, including carbon and membrane filters.
• 😀 The system includes sensors for monitoring temperature and turbidity at various stages, with data displayed on a monitor connected to Arduino.
• 😀 The final stage of the system boils the purified water, making it drinkable through a dispenser connected to the boiling system.

Q & A

What is the main focus of the presentation?

The main focus of the presentation is a water purification project developed by a team from Bengkulu, Indonesia, which aims to provide clean drinking water by filtering and purifying river water using a multi-stage filtration process.

What is the purpose of the water filtration system discussed in the presentation?

The purpose of the water filtration system is to remove microorganisms, contaminants, and impurities from river water, making it safe for consumption.

What are the stages of filtration in the water purification process?

The stages of filtration include: 1) Pebble filtration to remove larger particles, 2) A layer to absorb iron and manganese, 3) A biological layer to filter out finer particles, 4) Activated charcoal to remove odors and organic compounds, followed by further filtering through a series of carbon and membrane filters.

What role does the activated charcoal play in the water purification system?

The activated charcoal is used to remove bad odors, colors, and organic compounds from the water, improving its taste and quality.

How does the system handle bacteria and viruses in the water?

The system uses an RO (Reverse Osmosis) membrane that kills bacteria and viruses, ensuring that harmful microorganisms are removed from the water before it is deemed safe for consumption.

What are the key components used for water filtration in the system?

Key components of the water filtration system include pebbles, iron and manganese absorbers, biological filtration media, activated charcoal, carbon filters, and a reverse osmosis (RO) membrane.

What is the function of the sensors in the water purification system?

The system is equipped with three sensors: 1) A temperature sensor (DS18B20) to measure the temperature of the water, 2) Two turbidity sensors to measure the clarity of the incoming river water and the filtered water, providing real-time monitoring of water quality.

How is the temperature and turbidity data displayed in the system?

The data from the temperature and turbidity sensors is displayed on a monitor connected to an Arduino, allowing users to easily monitor the conditions of the water at different stages of purification.

What is the role of the 'boiling water' system in the water purification process?

The boiling water system heats the filtered water using electric heating elements. This helps further ensure that any remaining pathogens are eliminated, making the water safe to drink.

How does the system ensure the water is ready for consumption?

Once the water passes through all the filtration stages, including boiling, it is dispensed through a faucet, and the system ensures that it meets safety standards, ready for direct consumption.
