MGF Working multi grade filter and Pressure Sand filter working principle and internal structure #1

Summary

This video explains the internal structure of a multi-trade center, focusing on filters like MG and HP laptop filters. The speaker highlights the components of the filter system, including hangers, plates, and nozzles, and explains their functionality. The video discusses different layers of media used in the filter, pressure requirements, and distinctions between MG filters and pressure sand filters. The tutorial offers insights into industrial filter systems, how they operate, and answers common interview questions related to filter technology. Viewers are encouraged to watch the full video for a comprehensive understanding.

Takeaways

• 🏭 The video discusses the internal structure of multi-stage water filters used in industries.
• 🏗️ MGFH (Multi Graded Filter) is a type of filter that looks similar to a mountain externally but has a complex internal structure.
• 💧 The filter's top layer is called the 'opening plate', which can vary in size from 500ml to 700ml or larger.
• 🚰 The filter can comfortably fit a man inside due to its size, and it is filled with media and gravel.
• 🔩 Cranes are used to lift heavy filters for placement and maintenance.
• 💦 The filter's outlet, called the 'header', has small nozzles that distribute water evenly across the media.
• 🌊 The nozzles are oriented upwards to prevent clogging and ensure water trickles down in small drops onto the media.
• 🛠️ The filter includes a 'spotting lace' to support the media and prevent it from moving or settling unevenly.
• 💎 The filter uses various layers of gravel and pebbles of different sizes to support the media and facilitate water filtration.
• 🌡️ The video mentions that the pressure inside the filter should not exceed 4 kg/cm² to avoid damage.
• 📊 The difference between TDS and TSS is explained, with TDS being the dissolved impurities in water and TSS being the total suspended particles.

Q & A

What is the main topic of the video?

The main topic of the video is explaining the internal structure of a multi-stage center, specifically focusing on the design and components of a filter system.

What does the term 'MG of HP' refer to in the context of the video?

In the video, 'MG of HP' likely refers to 'milligrams of hardness per liter,' which is a measure of water hardness.

What is the purpose of the opening baffle in the filter?

The opening baffle in the filter is designed to hold a plate that prevents the media from being disturbed by the water flow, ensuring that the water can pass through the filter media without disturbing the layers.

What is the function of the 'header' in the filter system?

The 'header' in the filter system is a pipe that directs water flow, ensuring that the water trickles down through the media in a controlled manner, preventing the media from being disturbed.

Why is the mouth of the header directed upwards?

The mouth of the header is directed upwards to prevent the media from becoming compacted or clogged. This design allows water to trickle down in small drops, preventing the media from becoming compacted.

What is the purpose of the 'spooling rocks' in the filter?

The 'spooling rocks' are used to support the filter media and provide a stable base for the layers of media. They also help in evenly distributing the water flow across the filter bed.

What is the role of the 'supporting plate' in the filter?

The supporting plate is used to hold the various layers of media in place and prevent them from mixing or settling. It also helps in maintaining the structural integrity of the filter.

What is the significance of the 'flexible clear' mentioned in the video?

The 'flexible clear' is likely a type of flexible pipe or tubing used in the filter system to allow for easy expansion and contraction without breaking, ensuring durability and flexibility in the water flow.

What is the difference between a 'Preserv Send Filter' and an 'MJ Filter' as mentioned in the video?

The 'Preserv Send Filter' is designed to remove larger dust particles, up to 50 milligrams per liter, while the 'MJ Filter' is capable of removing smaller dust particles, up to 120 milligrams per liter.

Why is it important to check the water pressure within the filter?

It is important to check the water pressure within the filter to ensure that it is within the recommended range (1.5 to 4 kg/cm²) to prevent damage to the filter media and to ensure proper filtration.

What is the purpose of the 'selectors' in the filter system?

The 'selectors' in the filter system are likely a type of valve or control mechanism that allows for the regulation of water flow through different sections of the filter.
