Key Features:

1. » Dry, TFC, KNL-NF20 NF (Nano Filtration) membrane 100 GPD, pore size 0.0015 micron, BARC licensed & by ISO certified 9001:2015 company, suitable for soft water having TDS up to 250 ppm max. Compatible with 100 GPD pump, FR 450 CC along with good inline filters and working pressure should be between 80-90 PSI. In case of low pressure or high pressure, the result may vary, in case of high pressure, suggested to use PRV else membrane will get damage early.

2. » TDS Rejection rate around 20% with variation (± 5%), flux rate around 35 ltr/hr, must be used along with good quality inline filters. The membrane naturally maintains healthy minerals (TDS) in drinking water around 85% with variation of (± 5%) and reduces TDS around 15% with variation of ± 5% only from feed/raw water. With more TDS water taste will be little hard compare to RO water or demineralized water. Please note 150 ppm to 300 ppm range is known as mineral water. Demineralized water user may feel little hard water taste due to more minerals in drinking water.

3. » The membrane must be used where the tap water TDS is less than 250 ppm else the result may not be satisfactory and the water taste will be too much hard. Service life is around 20000 liters or 18 months, subject to use with good quality of inline filters (especially sediment and pre- carbon filter). The membrane reduces negligible pH from raw water and does not make water acidic unlike RO membrane.

4. » The NF20 pore size is 0.0015 microns, 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 and breaks further in smaller size. The NF20 membrane eliminates all the impurities like mercury, arsenic, bromide, fluoride, lead etc. including germs and flushes them through rejected water.

Warranty details: The membrane does not cover any warranty. The performance of the membrane depends on user skill with proper installation, feed water quality, and pump with required working pressure. Once put to use cannot be taken back except in case of manufacturing defect.

Installation guidelines: Before using membrane, make sure the previous SV, pump etc. are functioning properly. Before inserting new membrane, the membrane housing must be cleaned properly & make sure membrane housing o ring point is 100% circular. Without using FR, discard 2-3 liters water first and then use new FR delivered to you in the packet as per flow direction. FR if used in reverse direction will led to damage of the membrane. Let the machine run for 20-30 minutes and then check the result with good quality TDS memter. The result will be as per descriptions.

Ideal drinking water: TDS is not impurities but composition of minerals (like calcium, magnesium, iron, sodium, zinc, copper, potassium etc.). As per WHO or other prominent institutions, ideal drinking water should have TDS between 100 ppm to 300 ppm, less than 100 ppm is considered poor, less than 50 ppm not permissible in long run but causes lots of health issues, the range 150 ppm to 300 ppm known as mineral water if the water is free from impurities. Water taste mainly depends on TDS, with more TDS water taste hardness increases. The user who consume RO water or demineralized water may feel hard water taste compared to RO water/demineralized water or normal bottle packed water. The water taste develops in couple of weeks’ time.

Advantage/Benefits of using NF membrane (based on TDS of your tap water), retain essential mineral in drinking water without using TDS controller, water recovery upt to 55% (depends on nf variant). But TDS controller permits the return of impurities to your drinking water.
