Teknologi Pengolahan Air Gambut menggunakan Nonofiltrasi dan Kalsium Laktat menjadi Air Minum

Summary

This video showcases a groundbreaking water purification project at Rumah Sakit Umum Daerah Kabupaten Kubu Raya. Researchers are transforming peat water from a local river into safe drinking water using a combination of Reverse Osmosis (RO) and Nanofiltration (NF) systems. By adding calcium lactate, the water is enriched with essential minerals. The project not only focuses on ensuring the water meets health standards but also aims to promote sustainability by reducing plastic waste with reusable containers. The result is a high-quality, mineral-enriched drinking water, safe for consumption and beneficial for health.

Takeaways

• 😀 The RSUD Kubu Raya hospital has developed a water treatment process using two types of filtration systems: Reverse Osmosis (RO) and Nanofiltration (NF).
• 😀 The goal of the research is to treat peat water from a nearby river to make it potable by comparing the performance of RO and NF systems.
• 😀 The NF system is relatively new in water treatment research, making this a unique study in the field of nanofiltration.
• 😀 Calcium lactate is added to the treated water to ensure it meets the recommended calcium levels for drinking water, with a target of 250 mg per liter.
• 😀 The NF system is set to process water at a rate of 7 liters per minute, and the pressure is adjusted between 2 to 4 bars during operation.
• 😀 The NF system operates at a high capacity, with a pump capable of processing up to 4,000 liters per hour, unlike the RO system which is limited to 2,000 liters per day.
• 😀 The treated water is passed through membranes with a pore size of 0.001 microns, which filters out bacteria and viruses, making the water safe to drink.
• 😀 The process not only ensures the water is clear and safe but also enhances its mineral content with added calcium lactate for health benefits.
• 😀 The study also compares the water quality of treated water with commercially available bottled water and regular bottled gallon water, showing comparable or better results in terms of pH and mineral content.
• 😀 The hospital aims to contribute to the 'Go Green' initiative by reducing waste, using reusable water containers, and promoting sustainable water consumption.

Q & A

What is the main objective of the research conducted at the hospital?

The main objective of the research is to process peat water from the river behind the hospital into clean drinking water using two membrane filtration systems: Reverse Osmosis (RO) and Nanofiltration (NF), to compare their results and effectiveness.

What are the two main membrane filtration methods used in the study?

The two main membrane filtration methods used are Reverse Osmosis (RO) and Nanofiltration (NF).

Why is Nanofiltration being tested, and what is its potential advantage over RO?

Nanofiltration is being tested because it has limited research in this area. The potential advantage is that it can handle larger water flows with lower energy consumption compared to RO, which may make it more cost-effective and efficient for processing larger volumes of water.

What role does calcium lactate play in the water treatment process?

Calcium lactate is added to the water after the filtration process to ensure the water contains the necessary minerals, specifically calcium, which is important for human health. The solution is dosed at 250 mg per liter to meet health standards.

What are the key differences between the Reverse Osmosis (RO) and Nanofiltration (NF) systems in terms of their performance?

The RO system is known for its ability to produce high-quality drinking water by removing almost all contaminants, including bacteria and viruses. However, NF allows for higher water flow and uses lower energy, making it potentially more suitable for handling larger volumes of water.

What was the initial quality of the peat water used in the research?

The peat water from the river behind the hospital had a physical appearance that was not clear, with a pH below 5 (around 4.5-5), which required treatment to meet drinking water standards.

How is the water flow rate controlled in the Nanofiltration process?

The water flow rate in the Nanofiltration process is controlled by setting the flow meter to 7 liters per minute, which is the optimal flow rate for this system in order to process the water effectively.

How does the pressure in the Nanofiltration system compare to the RO system?

The pressure in the Nanofiltration system is typically set between 2 to 4 bars, which is lower than the pressure required for the RO system, making NF more energy-efficient.

What was the result of the water quality after treatment using the Nanofiltration system?

After treatment, the water was clear and met the health standards for drinking, with a pH level of 8.8, which is close to the acceptable range of 6.5 to 8.5 as per health regulations.

What are the potential health benefits of the treated water?

The treated water, which contains added calcium lactate, not only meets the standard for clean drinking water but also provides essential minerals, such as calcium, which contribute to the overall health and wellness of individuals consuming it.
