Key Features:

Stage 1 » Polypropylene (PP) Spun 10 inches , pore size 5 micron, Captures all particles larger than 5 microns (clay, sand, rust, colour, heavy metal etc.) and then supplies crystal clean water to sediment filter. (Usually need to replace at interval of 6 months in normal water conditions). The 10 Nos antiscalant balls (food grade) is filled in spun filter hole (centre). The balls prevents mineral scaling inside the filters & early blockage. The antisclaants balls are used where tap water TDS is more than 600 ppm.

Stage 2 » Sediment Filter (Common in each case) (absolute 5 microns) made from polypropylene & sediment special cloths. Polypropylene is resistant to bacterial growth. The filter captures suspended particles such as sand, silt, loose scale, clay and organic material from the water those if passed from prefilter and then goes to activated block carbon filter. Service life is 10000 liters.

Stage 3 » Activated Carbon Block Filter (Common in each case) (1000 IV) Made from activated carbon in solid cylindrical block, absorbs harmful chemicals, toxic substances, iodine, chlorine etc., removes odour, and enhances water taste. We the KNL uses only activated block carbon over charcoal granules. Charcoal granules (filled half in filter) floats when water goes through and cannot absorbs the chlorine and impurities properly. Service life 10000 liters.

Stage 4 » KNL NF80 Membrane, BARC licensed, 100 GPD, pore size 0.0002 microns. The membrane reduces TDS around 80% with variation of (± 5%) from feed water and maintain all essential minerals around 20% with variation of (± 5%) in drinking water naturally. Flux rates around 23 litres per hour. The membranes remove arsenic, mercury, lead, cyanide, bromide, pesticides, herbicides, VOCs, bacteria, protozoa, viruses, germs, microbes, colour, smell and all other contaminants from feed water and flushes them through rejected water. The UV cannot eliminate these impurities and TDS controller permits these impurities back in your drinking water. Please note, in case of high rise building, large concrete overhead tank or where the tap water pressure is excessive, recommended to use PRV to control the working pressure else membrane will get damage early.

Warranty details: The membrane and inline filters 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. Once put to use cannot be taken back except in case of manufacturing defect.

Installation guideliens: Before using membrane and inline filters, 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. Withou using FR, discard 2-3 liters water first and then use new FR delivered to you in the packet as shown flow direction. FR if used in reverse direction will led to damage of the membrane. The food grade antiscalant balls need to fill in the hole of spun filter while installation. The balls prevent mineral scaling inside the filter and enhances the filter and membrane life else may get clogged early. 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.
