|#||Advantages||How to use|
|1||Removes Bacteria upto 99.9℅||Gently wash the filter housing and filter candle before using.|
|2||Removes almost complete turbidity & clear water is produced.||Connect the filter inlet pipe to the tap (which is connected to the overhead tank).|
|3||No electricity needed and no chemicals added||The filter outlet pipe is placed into the container or storage tank/vessel.|
|4||Provision to remove organic substance or coloring material if they are present in the feed.||The water flow is shown in the schematic diagram.|
1.1 Initially, allow the first 4-5 liters of water to flow out of the filter.
1.2 When the flow of the water is reduce or the filter is clogged, just use running Recommended for Tap water and wipe the surface of the membrane softly using a foam / cloth. This will remove superfine solids deposited on the membrane which you would have been otherwise drinking.
a) Don’t use the brush or sharp material to wipe, it may damage the membrane
b) The membrane is not pressed too hard
c) While putting the bowl cover back, ensure that the O ring is placed in the groove provided on top inside of bowl bottom.
1.3 The above product works under standard condition:-
a) Turbidity: <1NTU
|2||Almost maintenance free, expect occasional cleaning of suspended solids deposited on filter surface which doesn’t take more than 2-3 minutes time.|
|3||Almost maintenance free, expect occasional cleaning of suspended solids deposited on filter surface which doesn’t take more than 2-3 minutes time.|
|4||*Special UF filter- Reduces excess elements like Arsenic& iron/ fluoride or the combination of both as per Customers requirement.|
|#||Frequently Asked Question|
|1||Question: What is NIRNAL TM Special ULTRA-FILTER(UF) unit/assembly ?
Answer: NIRNALTM SPECIAL UF is a Unique, HI-tech but very user-friendly domestic water purifier. It is an affordable alternative to purify water. Which removes bacteria, virus and complete turbidity to produce crystal clear water. Additional the other products reduces Arsenic & Iron and one more which removes fluoride.
|2||Question: On what principal does it work?
Answer: It works on the ultra filtration membrane technology which removes Bacteria, virus, turbidity & foul odour from water( Additional the other products reduces Arsenic & Iron and one more which removes fluoride)
|3||Question: How does it work?
Answer: It has four-stage filtration.
Stage-1: Porous filter candle to remove Dust particles upto 5 microns.
Stage-2: Arsenic, iron and fluoride removal ultra filtration unit treatment candle.
Stage-3: Activated Carbon to remove odour and color.
Stage-4: Ultra filtration with 0.2 micron membrane which removes all Suspended solids, bacteria and viruses
|4||Question: Does it require electricity?
Answer:No. NIRNALMTM SPECIAL UF works without electricity. It is a 0.2 micron ultra filtration, and it only requires water hydrostatic pressure between 10psi to 35psi. (Water head should be minimum 15 feet above water purifier).
|5||Question: Is it a very complicated system?
Answer: In fact, it is the most simple water purifier you have ever used.
|6||Question: Why is it better than UV system?
Answer: UV is ultraviolet light that covers a specific wavelength of the light spectrum, and it is about 85-87% effective at its absolute best level of performance when new, with a steady and measurable decline over time. It never kills bacteria but just inactivates them. Effectiveness depends on parameters like lamp capacity, rate of flow, wavelength etc. it is electricity-dependent and expensive. It needs costly maintenance contracts.
|7||Question: What is the difference between RO system and NIRNALTM SPECIAL ULTRA-FILTER?
Answer: RO removes even the finest radicals/ions making water dead. The minerals in the water, which are useful, are filtered out unlike NIRNAL SPECIAL ULTRA-FILTER. Very high initial capital cost. It has high capacity pump leading to high running cost. 60-70% input water is wasted and gets clogged easily with such elements like Arsenic & Iron/ fluoride. Frequent replacement requirement of expensive cartridges. High AMC charged by the supplier.
|8||Question: What is the life of NIRNALTM SPECIAL UF?
Answer: Life of membrane is approx 2 years. It only requires occasional surface cleaning with wet, soft cloth. The membrane can be replaced at home very easily; it makes NIRNALTM SPECIAL UF maintenance-free water purifier.
|9||Question: Does it purify salty water?
Answer: No it does not purify salty water.
|11||Question: Where it can be used?
Answer: It can be used at every place where there is a requirement of pure water. It can be used at hospital, homes, schools, offices etc.
