MTDS in Water Purifiers: Meaning, Benefits, and Working Mechanism

MTDS in Water Purifiers: Meaning, Benefits, and Working Mechanism

Due to the escalating environmental pollution in water sources, people are looking for an effective water purifier to provide them with pure and safe drinking water. While terms like RO and UV are easily understandable, concepts like TDS controller and MTDS might be more complex yet crucial for making an informed decision. Therefore, gaining a clear understanding of these terms before purchasing a water purifier is a prudent choice to ensure it aligns with your preferences. Read on to know more about MTDS technology.

What is MTDS Technology in Water Purifiers?

MTDS, also known as the Manual Total Dissolved Salts Controller or TDS Controller, is a device that helps maintain the right balance of minerals in purified water. During the water purification process, essential minerals like calcium and magnesium can be inadvertently removed along with impurities. MTDS ensures that an appropriate level of these minerals is retained, enhancing the taste of purified water while adhering to purity standards. This also increases the life of the water purifier. That’s because high levels of hardness-causing minerals like calcium and magnesium can lead to scale buildup in water purifiers, reducing their effectiveness and durability. However, MTDS adjusts the amount of minerals and dissolved solids in the water, which in turn protects the water purifier from scale buildup and long-term corrosion. This makes water purifiers with MTDS a smart and cost-effective choice for homeowners.

Features of Monitoring MTDS

  • Taste Improvement

    MTDS ensures that purified water maintains a desirable taste by regulating the mineral content. It adjusts the Total Dissolved Solids (TDS) of purified water to deliver you water that is healthy and matches your taste and preference.
  • Desired TDS

    The primary function of MTDS is to preserve the essential minerals and salts in your water. This helps prevent over-mineralization or under-mineralization, maintaining an optimal balance of essential minerals like calcium and magnesium.
  • Health Benefits

    Increased levels of certain dissolved solids and minerals may have health implications. MTDS removes harmful minerals and dissolved solids from the water ensuring that water meets safety standards for human consumption.
  • pH Balance

    MTDS keeps the salt level in check, ensuring your water has the right pH. This means the water is perfect for drinking and all sorts of everyday uses.
  • Versatility

    Water purifiers with MTDS are versatile and adaptable, making them suitable for use in diverse environments with varying levels of water quality.

How Does an MTDS Regulator Work?

The MTDS regulator is generally connected to the purifying source of a water purifier. For instance, if your water purifier has an RO membrane and UV lamp, the MTDS regulator will be connected to these purification technologies. This way, the controller can adjust the TDS level of the purified water as per your taste and preference.

Advantages of MTDS

One of the primary benefits of MTDS is its capacity to adjust TDS levels according to water sources. This adaptability ensures the water purification system remains effective in different locations with varying water quality and mineral content. Consequently, homeowners can enjoy consistent water purity and taste regardless of their residence. Another significant advantage of MTDS technology is its capability to preserve essential minerals like calcium and magnesium, which are inadvertently removed during the purification process. These minerals are vital for maintaining good health and ensuring proper bodily functions. By reintroducing the right balance of minerals, MTDS enhances the taste and quality of purified water, making it healthier and more enjoyable to drink.
