6 Best Water Purifier with TDS Controller in India 2024

Imagine moving into a new home in a city like Delhi or Mumbai. You’re thrilled to finally have your own space. Or recently the municipal water supply has become more polluted, with higher TDS levels and an unpleasant odor. Your old water purifier without TDS control is not able to handle the deterioration in water quality. When you turn on the kitchen tap, out comes water that is smelly, salty and leaves white stains on your stainless-steel cookware. Boiling it just concentrates the foul taste. You think of ordering bottled water but don’t want the cost and plastic waste. The solution? Investing in a quality water purifier with TDS controller. This allows you to remove the excessive TDS making the water unsafe, while retaining some essential minerals for healthy and tasty drinking water. So, today in this I will review some of the Water Purifier with TDS Controller in India. But before that a question arises- Why You Should Consider a Water Purifier with TDS Controller. Let’s dive into it.

Why You Should Consider a Water Purifier with TDS Controller

TDS stands for Total Dissolved Solids. It is a measure of the total amount of dissolved salts and inorganic materials present in water. A high TDS level indicates hard water which has excessive dissolved salts like calcium, magnesium, potassium, sodium, bicarbonates, chlorides, sulfates etc.

While essential minerals are needed in healthy water in moderate quantities, consuming water with very high TDS levels can lead to:

  • Unpleasant taste and Odor making water unpalatable
  • Scaling in water pipes, fittings and appliances due to hardness causing reduced lifespan
  • Increased soap/detergent usage as they do not lather properly in hard water

Water purifiers with built-in TDS controllers are designed to remove the excess salts and minerals from water to make it safe and tasty for daily consumption. They work by monitoring the TDS level of potable water and allowing adjustment of mineral content to achieve the desired TDS standard for optimized clean and safe drinking water.

Benefits of getting a water purifier with automatic TDS controller:

  • Removes excess TDS and makes water safe for drinking
  • Allows setting the optimal TDS level tailored as per your source water quality
  • Improves taste and palatability by reducing hardness and salinity
  • Enhances flavour of beverages and food preparations like tea, coffee, soups etc.
  • Protects water fixtures and appliances from scale buildup extending their life
  • Essential for health as it helps avoid issues linked to intake of hard water over time
  • Provides better soap lathering and requires less usage of detergent

For the average Indian household dependent on municipal tap water supply, investing in a water purifier with TDS regulation capability has become highly beneficial considering the deteriorating water quality in cities. It provides healthy water for all your drinking and cooking needs.

How Does a TDS Controller in Water Purifiers Work?

The TDS controller works in conjunction with the primary water purification technology in a water purifier. Here is a brief overview of the tds controller diagram and working principle:

  • The input water first goes through a pre-filter or sediment filter which removes visible dirt, mud, chlorine and large particulate matter.
  • It then passes through the main purification technology which could be RO membrane, UV disinfection system or UF membrane. This removes heavy metals like arsenic, fluoride, pesticides, microbes, viruses and the majority of dissolved salts and impurities.
  • The water coming out of this purification stage is very low in TDS since essential minerals get removed too in the process. The TDS at this point may be as low as 5-50 ppm.
  • Before delivering the water to the storage tank, it flows past the TDS controller. Based on the desired TDS setting, the TDS controller releases a calculated concentration of essential dissolved salts like calcium and magnesium back into the water.
  • This helps re-mineralize the water to the preset optimal TDS level. For instance, adding minerals to increase TDS from 50 ppm to 200 ppm for drinking purpose.
  • The treated water with the adjusted TDS is then stored in the tank for consumption.

Key Factors to Consider When Choosing a Water Purifier with TDS Controller

With many options available from brands like Kent, Livpure, HUL, AO Smith etc. choose your water purifier TDS controller carefully based on factors like:

  • Filtration Technology – Common types are RO+UV, RO+UV+UF, and RO+UV+UF with Mineralizer. Choose as per your input water quality. RO+UV+UF gives the most thorough purification.
  • Quality of Filters – The quality, expected life and filtration capability of pre-filters, RO membrane and post-filters is important for effective purification.
  • TDS Adjustment Range – The TDS controller should allow adjusting TDS from as low as 50 ppm to up to 2000 ppm levels or higher for flexibility.
  • Purification Capacity – Higher liters/day is better for households with greater water requirements. Choose minimum 10-12 liters/hr.
  • Purification Stages – More stages with pre and post filters ensures thorough contaminant removal for 100% safe water.
  • Convenience Features – Look for features like tankless operation, automatic start/stop, water level indicator, leak protection, filter change alarms etc. for ease of use.
  • After Sales Service – Choose purifiers from reputed brands like Kent, Livpure etc. that provide installation support and maintenance services.
  • Certifications – Look for certifications like ISI, CE, NSF that validate quality standards and safety.
  • Warranty – Opt for at least 1 year comprehensive warranty covering entire system.

Bepure 4G Hot & Cold Water Purifier RO+UV+UF+TDS+ Alkaline Purification

This 8-stage purifier combines reverse osmosis, ultraviolet, ultrafiltration, and TDS purification to reduce contaminants from water with up to 3000ppm TDS. During my testing, it effectively brought down the TDS level of my tap water from 2500 ppm to under 156 ppm – making it safe for drinking. The pre-filter catches large particles before they can damage internal components.

Water Purifier Buying Guide

Here are some tips to help choose the right reverse osmosis technology water purifier with TDS controller as per your requirements:

  • Test your water quality to determine TDS level and contamination. This will help decide on RO, UV, UF or combination system.
  • For municipal tap water supply, a TDS under 200 ppm is good. Increasing to 500-1500 ppm is optimal. For borewell/tanker supply, ideal TDS is 150-300 ppm.
  • Pick a purifier with at least 50-80 liters per day capacity for a family of 4-5 members. Go for higher 10-12 liters/hr models for larger households.
  • Installation near a drain point is needed for RO purifiers to release the wastewater.
  • Calculate your daily water requirement and pick right tank size. 5L is good for small family.
  • Ensure all pre and post filters are included. Mineral enhancement filter is ideal.
  • Choose purifiers with auto-start, auto-stop, water level sensors for convenience.
  • Pick models with filter change alarms and indictors to know when replacement is due.
  • Change filters and service the purifier regularly as per manufacturer. This maintains performance.
  • Keep an eye on the TDS level using a TDS meter.
  • When purchasing, check for certifications like ISI, CE, NSF for safety assurance.
  • Opt for comprehensive 1 year or more warranty and support plan for peace of mind.

Frequently Asked Questions

Q. How do I set the right TDS level on my purifier?

A. Check your input water’s TDS first. For municipal tap water, set around 500-600 ppm. For borewell/tanker water set between 150-250 ppm. Adjust up or down per taste.

Q. What is the ideal TDS for drinking water?

A. WHO recommends TDS under 500 ppm. For best taste, set between 150-300 ppm for RO, or 500-1000 ppm for tap water feed.

Q. Does TDS controller reduce water flow rate?

A. Yes, adding a TDS controller results in a 10-15% reduction in output, which is acceptable. The mineralization process takes time leading to slight slower flow.

Q. How do I maintain the TDS controller?

A. Very little maintenance is needed. Just ensure the controller is kept clean by wiping it periodically. Check if it’s functioning via the display readings. Replace batteries if using a standalone unit.

Q. When should the TDS controller be serviced? A. TDS controllers are fairly robust and would rarely need service. Only if the TDS adjustment or readings are very inaccurate even after filter change, you may need
