## Overview

The KNL-RO Membrane is a premium TFC dry RO membrane element designed for domestic water purifiers, licensed by BARC and ISO 9001:2015 certified. It features an ultra-fine 0.0001 micron pore size that reduces TDS by up to 93%, effectively removing viruses, bacteria, heavy metals, and chemical contaminants. With a high flux rate of 20-23 liters per hour, it outperforms standard membranes by delivering more purified water with less wastage. Suitable for feed water TDS up to 3000 ppm, it ensures optimal performance in hard water conditions. The membrane offers a service life of approximately 15,000 liters or 18 months, making it a reliable and cost-effective choice for health-conscious professionals seeking superior water quality.

## Description

TFC dry RO membrane element, 100 GPD, Flux rate around 21 ltrs/hr BARC licensed (Bhabha Atomic Research Centre transferred technology) & by ISO 2009:2015 certified company. Its pore size is 0.0001 micron and rejection rate is between 93% to 97%. The TDS will come down gradually, within 30 mints 90% TDS will come down and further within few days will come down more. The membrane is suitable for all kind of electric operated RO domestic water purifiers used with 100 GPD pump & with 450 flow restrictor, working pressure should be 80 PSI to 90 PSI, inlet pressure should not be more than 5 PSI. The membrane is suitable for extremely hard water having TDS up to 2500 ppm. The water born microbes/germs/virus size remain between 0.027 micron to 5 micron those are eliminated with 100% surety and being flushed through rejected water. The membrane also eliminates harmful chemicals, pesticides, herbicides, toxicity, bromide, fluoride, cyanide, arsenic etc. and other impurities from feed water and flushes them through rejected water but UV & UF cannot. Life of this membrane is around 15000 litres or 18 months whichever is earlier. As per WHO, BIS and EPA recommendations the drinking water up to 300 ppm remains in excellent range for drinking. All RO membrane reduces pH value and drinking water becomes acidic in nature and therefore recommended to use good quality Alkaline cartridge with RO Membrane. The recommended pH value of drinking water is 6.5 to 8.5 but ideal is pH is 7.2 to pH 8.2. Please note high alkaline and low mineral drinking water cause many health problems in long run. TDS adjuster allows impurities back into your drinking water and therefore choose right technology of membrane as per input water TDS. KNL provides varieties of membrane according to input water hardness. KNL-NF20, KNL-NF40, KNL-NF60, KNL-NF80 and KNL-RO membrane.

## Features

- TFC, Dry, KNL RO membrane, 100 GPD, pore size 0.0001 micron, BARC licensed & by ISO certified 9001:2015 co., suitable for feed water TDS between 1200 ppm to 2500 ppm or max 3000 ppm, compatible with100 GPD pump, FR 450 CC, working pressure (90 PSI to 100 PSI). Reduces TDS between 93% (± 3%). Result may vary a little further more due to place to place and due to feed water hardness compositions ratio.
- The normal RO membrane gives water 12-15 ltr per hour, but the KNL RO membrane gives water (19-21) ltr per hour, so the water wastage is very less compare to normal ro membrane. Water wastage is less means the rest of linline filters and pump running time will be less and therefore the maintenance will come down drastically.
- The water taste varies with minerals contents and therefore user may experience heaviness while drinking with more TDS water. The membrane eliminates all the impurities like fluoride, bromide, arsenic, germs, bacteria, virus, chlorine, cyanide, pesticides, herbicides etc. from drinking water and flushes them through rejected water Service life is around 15000 ltrs or 18 months whichever is earlier (subject to use with good quality sediment & activated carbon block carbon.
- As per medical recommendations, the drinking water should have minerals (TDS) between 100 ppm to 300 ppm and acceptable range of pH is between 6.5 to 8.5. Low TDS (mineral) drinking water cause health problems in long run. Always use new FR 450 with the membrane, partial blocked FR may lead unsatisfactory result and the membrane will get damage early too.
- TDS adjuster or controller is nothing but a bypass system to flow the water through carbon filter and then getting mixed with membrane treated water in a proportion to maintain TDS at desired level. But the bypass system allows impurities like arsenic, bromide, fluoride, cyanide and other impurities if exist in raw water. Therefore using KNL NF20, KNL NF40, KNL NF60, KNL NF80 or RO membrane as per feed water TDS is better choice.
- Users/Buyer are requested to check the TDS of feed water with good quality TDS meter and then place the order. The feed water TDS must be less than 3000 ppm. And users are also requested to check their/his/her water purifier cabinet space, pump and other specification compatibility before placing order.
- Contaminants molecule size remain greater than 0.01 microns, germs size from 0.027 microns to 5 microns, water molecule size is 0.000283 microns, dissolve compositions of mineral molecule size remain less than 0.0009 microns, but all NF Membrane pore sizes are 0.0015, 0.0010, 0.0005, 0.0002 microns & RO membrane pore size is 0.0001 microns, therefore the NF Membrane & Ro membrane does the job far better than the UV and TDS controller system.
- Warranty details - The membrane does not cover any warranty. The performance of the membrane and filters depends on user skill with proper installation, feed water quality, and pump with required working pressure (80-85) PSI. Once put to use cannot be taken back except in case of manufacturing defect.
- Strongly recommended to use antiscalant balls 10 pcs in prefilter spun filter hole. The antiscalant balls prevent mineral scaling inside the filter and enhances the service life of the membrane and inline filters. Else the membrane may clog early.
- Installation guidelines: Before inserting new membrane, make sure the membrane housing is clean else loose particles led to blockage of FR. The KNL-NF80 membrane need to flush for 30-40 minutes and then check the result. Water taste with more TDS may some people feel hard compare to RO water or normal bottle packed water but medically healthy to intake mineral enriched drinking water. Always use new FR 450 with the membrane, partial blocked FR or if used in reverse order the membrane will get damage early/immediately.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Must buy
*by J***F on 27 July 2021*

I replaced my R.O. membrane with this membrane after extensive research online. A local R.O. guy came and installed sediment filter, carbon filter, uv light n NF membrane. It's easy to install just like an ordinary R.O. membrane. Any professional working in field of water purifier technology can install it. My water TDS was as low as 45 coz of R.O. filter. My tank TDS is 450. Now after installing this d tds of drinkable water is 100-130.The water tasted sweet now as compared to earlier. It is a product which should be promoted irrespective of whatever tds your area has. As this nf comes with different models for different tds of water. Replace this nf with ur R.O. membrane as much soon as possible to drink good quality of water

### ⭐⭐⭐⭐ Good one but little bit costly
*by S***A on 1 November 2024*

After going through all the article related to RO and water condition, I decide to go with nano filter as it best serves the purpose. Nano filter is as effective as a RO as both remove all the micro-organisms/virus/chemical/lead/arsenic present in water while reducing the TDS. There is no difference is water quality except the TDS level when comparing RO with nano filter. While RO suppress the TDS to below 50, then you have to use mineral/alkaline cartridge to bring back the optimal TDS level but in case of nano filter it is in range of 150-400 PPM which save your money on using additional mineral cartridge. Also, TDS adjuster in RO is a big scam so never fall for that marketing gimmick, if you have TDS controller in your existing RO then stop using it, ask technician to close that valve.Go with RO only when your water is not consumable even only one time or even after using some gravity filter, if those conditions are not true then you do not need a RO. Also, water wastage in RO is much higher like for every one glass of water, you are draining 3 glasses of water.I am using NF-40 filter and my tap water TDS is around 450 PPM, after using this filter TDS drop to 225 PPM and water wastage is around little bit more than one glass for every one glass of water (50-55% wastage). Overall, I am happy with my purchase.

### ⭐⭐⭐⭐⭐ good for below 200 tds water
