- BARC licensed & ISO 9001:2015 certified TFC Dry NF (Nano filtration) Membrane 100 GPD, service life up to 15000 litres. User/buyer is requested to check the feed water TDS and then accordingly select the right model as per your need. The membrane NF20/NF40/NF60/NF80/RO Membrane reduces TDS from feed water (20-30), (40-50), (60-70). (75-85) and (< 94) % respectively. Max 2% result may vary due to other factors..
- Membrane flux rate (volume of treated water) – NF20/NF40/NF60/NF80/RO gives (25-30)/(24-26)/(22-25)/(20-23)/(18-20) litres per hour respectively. Compatible with 100 GPD pump and FR 450 with working pressure 80-90 PSI..
- Purification Stages – 1) Prefilter fitted with PP spun, 130 GSM, 10 inches, 2) Sediment filter absolute 5 microns with pp layer and fine cloth combinations, 3) Activated Solid Block carbon 1000 IV (not granules) , 4) NF/RO membrane, 5) Activated post carbon, 6) AAA cartridge with regulator and 7) SS -304 (Steel UV barrel fitted with quartz glass and UV lamp). In case of NF80 and RO model Antiscalant balls are used in prefilter that prevent scaling inside the filter and enhances the filter life..
- Membrane Functions – All the NF or RO membrane reduces TDS (rate varies on membrane variant) from feed water, removes contaminants like arsenic, bromide, lead, pesticide, icides, fluoride, toxic material etc. including germs/microbes from feed water. The tap water pressure must be within the range of 5 PSI to 10 PSI. In case of more than 10 PSI tap water pressure PRV is needed to protect the inline filters. Working pressure 80-90 PSI needed..
- Specification - Wall (or may be used with counter top too by making some arrangement) detachable tank system, built in ABS/Food grade plastic including all accessories. Storage tank 13 litres, electric consumption around 45 watt/hr while running motor, compatible with battery invertor. The large storage tank ensure the drinking water availability for ling time and in case of family gathering too..
- Warranty Details - The water purifier comes with one year warranty for electrical goods and 6 months for inline cartridges. The prefilter and cabinet with indicators do not cover any warranty. The Installation cost is separate (cost may vary between Rs. 500/- to 700/- depending upon distance from city centre). We provide PAN India Installation service in working days (Monday to Saturday between 10 am to 6.30 pm) but in some remote area may be difficult but video call assistance is available..
- Maintenance Schedule – Spun filter require to replace at interval of 5-6 months in normal water condition but if feed water is visibly dirty then may need to replace early. The inline filters including membrane having service life more than 10000 litres in normal water conditions. A family normally consume 6000 litres per year, easily last up to 18 months. After 18 months service kit replacement is needed. The annual cost comes around Rs. 3000 including visit charges. (Conditions applied).
- Medically drinking water – The drinking water should have 100 ppm to 300 ppm TDS. 150 ppm to 300 ppm known as mineral water, less than 100 ppm is considered poor. With more TDS, some people may feel heavy taste initially compare to low TDS drinking water. TDS is not impurities but composition of minerals and those are calcium, magnesium, iron, copper, zinc, etc. and these minerals are needed for good in acceptable range else low TDS causes problem in long run..
- Components - Prefilter fitted with pp spun filter 10", pH testing kit, pipe approx 4 mtrs, brass nipple with pvc on/off diverter valve and inlet connector, ss screws, user manual cum warranty card and chrome tap. Buyers are requested to check the tap water TDS before placing order..
KNL y Drops Model purifiers’ purification stages: Stage 1)
Prefilter fitted with 10 inches PP spun 130 GSM, 5 micron. The
filter captures suspended matter such as sand, silt, loose scale
& clay particles. Stage 2) Sediment filter absolute 5 microns
with pp layer and fine clothes. The filters captures furthermore
smaller particles of clay, sand, suspended particles, clay, silt
etc. and then supplies clean water to the rest of the filters. 3)
Activated Carbon Block filter made from compressed carbon of 1000
IV, very high absorption rate of impurities like chlorine,
pesticides, icides, toxicity, smell and other harmful
s and then supplies chlorine free water to membrane Stage
4) KNL NF20/NF40/NF60/NF80 (BARC certified) membrane: TFC dry 100
gpd, pore sizes are 0.0015/0.001/0.0005/0.0002 micron
respectively, reduces TDS from feed water
(20-30)/(40-50)/(60-70)/(75-85) % respectively, flux rate
(25-30)/(23-26)/(22-24)/(20-23) litres/hr respectively, water
wastage is very less compare to RO membrane and hence reduces
maintenance drastically. Please note water molecule size is
0.000283 micron, water born bacteria/germs/viruses sizes remain
between 0.027 micron to 5 micron and contaminants like arsenic,
bromide, fluoride, lead, heavy metal etc. remains greater than
0.01 micron and therefore all the NF Membrane variants mentioned
above removes all contaminants and germ from feed water and
flushes them through rejected water. The 100% feed water passes
through the NF membrane only and therefore UV is not required but
for those who need additional safety, the SS UV introduced. Stage
5) Activated Post Carbon (Coconut Shell): Coconut is
antibacterial agent and therefore inhibits the bacterial growth
and sweeten the water taste. Stage 6) PH Cartridge - AAA Filter -
is used with regulator to maintain balanced pH in drinking water.
Stage 7) SS UV 304 Grade with fitted quartz glass– Final stage,
the UV light kills the germs/microbes.
