Groundwater and borewell water sources in Delhi usually have high TDS. As a result, they contain heavy metals and salts, and a basic UV filter cannot remove dissolved minerals. To know whether you need an RO purifier in Delhi, use a TDS kit to measure your tap water quality. A handheld TDS meter will give you a basic idea of whether your water&#8217;s TDS level is high.\u00a0<\/span><\/p>\n<p><strong>Also Read: <a

Again, when municipal water is in short supply, many families in South Delhi, Noida, and Gurgaon switch to a borewell or private tanker. As it passes through, groundwater carries salts and minerals from the rocks. As a result, the water has high total dissolved solids. This increases the water&#8217;s hardness.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">With tanker water, it is difficult to judge whether it will be hard. If the source is disclosed, the chances are low. However, most tanker water suppliers do not disclose the source and may also rely on borewell water.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Is_the_TDS_Level_High_in_Noida_and_Gurgaon_Water\"><\/span><b>Is the TDS Level High in Noida and Gurgaon Water?\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Water hardness and high TDS depend on the water source. If your household relies on municipal supply, you&#8217;ll likely get soft water. Common signs of hard water include white scales on buckets, kettles, or utensils. You may also find it hard to wash shampoo out.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">According to India\u2019s drinking water standard, IS 10500, 500 mg\/L is considered the acceptable limit for TDS. UV and UF water purifiers can remove germs, but they don&#8217;t work at high TDS levels. RO water purifiers can reduce TDS in Delhi NCR.\u00a0<\/span><\/p>\n<p><b>Also Read: <\/b><a href=\"https:\/\/www.rentomojo.com\/blog\/reuse-ro-water\/\"><b>Can You Reuse RO Waste Water? 6 Ways To Use Reject RO Water!<\/b><\/a><\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Do_RO_Water_Purifiers_Work_in_Delhis_High_TDS\"><\/span><b>How Do RO Water Purifiers Work in Delhi\u2019s High TDS?\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">RO water purifiers run through these stages to deal with the high TDS levels in water:\u00a0<\/span><\/p>\n<p><b>1.

If the feed water is above that rating, the output TDS goes up, and the membrane wears out faster. You can check the \u2018maximum supported TDS\u2019 on the specification list against a reading of your own water. For example, Rentomojo shows 2,000 ppm on the product page for DriftGo and DriftPro.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"TDS_Controller_for_RO_Purifiers\"><\/span><b>TDS Controller for RO Purifiers\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">TDS controllers function by adding a small amount of filtered water that has not passed through the RO membrane.

It happens for the following reasons:\u00a0<\/span><\/p>\n<p><b>1. Sediment: <\/b><span style=\"font-weight: 400;\">Sand, silt, and clay can choke the pre-filter, and then the effect is on the membrane \u2013 only if the pre-filter has not been changed for a long time.<br \/>\n<\/span><b>2. Iron: <\/b><span style=\"font-weight: 400;\">Dissolved iron reacts with air and forms a rusty deposit that adds a layer on the membrane.<br \/>\n<\/span><b>3. Hardness: <\/b><span style=\"font-weight: 400;\">Magnesium and calcium create a layer of scaling on the membrane surface.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you notice the flow slowing, it may be a sign. Storage tanks take longer to fill, and the output TDS keeps increasing. RO membrane is an expensive component of the purifier, and changing the pre-filters keeps maintenance costs lower.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Does_RO_Remove_Iron_and_Hardness_from_Water\"><\/span><b>Does RO Remove Iron and Hardness from Water?\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Yes, an RO membrane eliminates dissolved iron, calcium, and magnesium along with other salts. RO water purifiers can handle hard water in Delhi. However, high iron is an exception because it affects the membrane over time. You can check the manual to see the maximum input of iron the RO purifier can handle. An iron filter sometimes works well with the purifier.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_Often_Should_You_Replace_an_RO_Membrane\"><\/span><b>How Often Should You Replace an RO Membrane?\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">There is no fixed schedule for replacing the RO membrane. It depends on input TDS, hardness, sediment, iron, and how much water a household uses. It wears out faster on hard borewell water than on municipal water supply. Replace the membrane if output TDS remains high or flow is low after replacing the pre-filters.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Should_You_Buy_or_Rent_an_RO_Water_Purifier_for_Hard_Water\"><\/span><b>Should You Buy or Rent an RO Water Purifier for Hard Water?\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">For borewell water, the purchase price is the only starting point. You need to change the pre-filters and membranes because iron-rich, silty, hard water can wear out the filters faster. Each replacement requires a technician visit.
