What are the benefits of combining multiple technologies? Go to Top
Using a hybrid or combination of technologies versus a single technology enables water treatment systems to address a wider range of contaminants than if they were to use one technology alone. A revolutionary 3-multi stage treatment process combining filtration, disinfection and adsorption. Zero B use more than one stage of water treatment to assure great tasting, high quality water from every system we offer.
What are the differences in the technologies used for treating drinking water? Go to Top
Distillation, reverse osmosis, ultrafiltration, ultra violet light, ozonation and filtration are among the most common water treatment technologies. You can easily refer to a technology comparison and compare the differences using a handy technology comparison chart. Zero B highly recommends that you consider how a system performs against all classes of contaminants, including microbiological, organic, inorganic, and pesticide contaminants.
What problems does hard water cause? Go to Top
Scale formation on the inside of pipes, water heaters, showers causing choking of pipes, loss of energy in heaters and clogging of showers.
In cooking hard water spoils the taste and needs more time to cook.
In washing, clothes requires more soap. vessels leave white stains.
It causes discomfort on skin and hair on bathing.How does a water softener work? - The Ion Exchange Process
The idea behind a water softener is simple. The Calcium and Magnesium ions in the water are replaced with ions of salt (either Sodium or Potassium). These salts do not precipitate in pipes or react badly with soap and therefore eliminate the hard water problem.
Water softeners contain Sodium rich ion exchanger resins that are designed to remove ions, mainly positively charged Calcium (Ca2+) and Magnesium (Mg2+) ions. This resin media exchanges the hardness minerals with its Sodium as the water passes through the media, thus making the water soft. This is called as the softening process.Does the softener cartridge needs to be replaced after softener stops giving soft water? Go to Top
In the process of softening the resin beads now exhausted with Calcium and Magnesium can no longer soften the water. Then it is time to recharge the resin. Recharging involves passing salt water ( common salt ) slowly through the resin bed in the reverse direction for a given time.
How does the POU softener compare with other softeners in the market?
Most softeners in the market are point of entry products (whole house ) hence large in size and high on cost.
Other POU softeners are not user friendly. For recharging the softener the salt solution is to be made and poured from a funnel or allowed to trickle via a hanging bag. Also the port tubing's have to be physically reversed on the unit.
The compact wall mounted POU softener has a multiport valve. Which directs the salty water to a separate drain line during recharging (no need to reverse the tubing's ). Solid salt has to be filled into the POU unit for recharging. The product is user friendly.Where can the POU softener be connected at home? Go to Top
POU softeners can be connected to geysers, showers, wash sinks and washing machines.
How much soft water will the product POU softener give?
Based on the Hardness content in the raw water the output of the softener can be estimated, typically if inlet hardness is say 500 ppm as CaCo3 in Soft water output will be around 300 litres.
How much of common salt is required for recharging the softener?
Every time the softener stops giving soft water, the POU unit has to be filled with around 500gms of salt and left in the recharging mode.
For how much of hardness is a softener required? Go to Top
Water with around 20 ppm hardness is termed as soft
Water upto 60 ppm hardness slightly hard
Water upto 120 ppm moderately hard (improves with a softener)
Water upto 180 ppm hard (big improvements with softener)
Water over 180 ppm hardness – very hardWhat does RO purifier comprise of? Go to Top
Typical RO purifiers are multistage purification system. The first stage is sediment filter which reduces suspended particles. The second stage is carbon filter which reduces volatile organic matter, chlorine and other odour & taste causing compounds. Third stage is the membrane filtration using RO membrane. It is responsible for rejecting upto 98% of the total dissolved solids in the water. This is where purification takes place.
Conventional RO purifiers do not guarantee 100% bacterial removal all the time, especially in the event of an accidental failure of RO membrane. Pristine has got additional back up purifier which ensures 100% bacterial removal.
RO water purifiers-
Do RO purifiers require frequent maintenance? Go to top
Maintenance needs of RO purifiers depend on the quality of incoming water. High turbidity in incoming water tend to choke first stage sediment filter frequently. Organic load and chlorine in the incoming water decide the life and efficiency of second stage activated carbon filter. Calcium, magnesium or other salts tend to scale third stage RO membranes which may require cleaning or replacement. Thus RO purifiers require planned maintenance schedules for replacements and cleaning.
Ion Exchange provides full fledged after sales service through its countrywide network for all its products.
Do RO purifiers remove pesticides? Go to top
RO purifiers reduce pesticide level in the water to certain extent. But a specially designed RO purifiers like Pristine is tested to remove generally encountered pesticides in surface and ground waters.
Can RO products be installed for any kind of water?
RO products cannot be installed for any kind of water. Contaminants like Iron, Manganese and Oil can cause severe damage to RO membranes. The manufacturers of RO purifiers specify the maximum limit of contaminants (like heavy metals, organics, nitrates, chlorine, oil, hydrogen sulphide, silica, iron, manganese, etc.) in water. They also mention maximum limit of feed TDS (generally 1500 to 2000 ppm) to ensure adequate RO membrane life.
Why do you need an RO purifier at home or office? Go to Top
Municipal water treatment plants are miles away from our homes, treated water is likely gets contaminated during distribution.
Chlorine introduced by treatment plants can form harmful disinfection by-products such as TTHMs (total trihalomethanes) and HAAs (haloacetic acids) in drinking water. These chemicals are known carcinogens or cancer causing.
Hygiene of underground and overhead tanks of apartments and residential complexes is always a question.
Ground water is invariably high in salts and harmful chemicals.
Conventional water purifiers does not ensure complete removal of harmful chemical, excessive salts and all germs from drinking water.
Timely supply of bottled water at homes and offices is based on reach of the distributor.What are the signs in raw water to go in for a RO water purifier?
A Reverse osmosis purifier should be purchased by anyone who is concerned about the purity/quality, hard water taste odor or levels of dissolved chemicals and excessive minerals in their drinking water.
What factors should a buyer look for in a RO purifier? Go to Top
Is the product tested and certified from an accredited laboratory for complete removal of all organisms, harmful chemicals and for any specific chemical like Pesticide, Arsenic.
Does the product water quality meet international drinking water standards like USEPA, WHO.
Ensure that the product is from a company that thoroughly knows water purification – useful indicator is the number of years of experience and presence in this field.What kind of Service attention does this RO purifier need?
When a purifier conditions or traps impurities, its filtering elements become a storehouse of dirt and disease causing organisms. Service is required for periodic washing, sanitizing and replacement of these filters.
This ensure good life of the filtering elements and therefore consistent purification performance.What impurities are removed by RO? Go to Top
Reverse Osmosis system removes excessive salts, bacteria, virus, cysts, suspended solids and all harmful chemicals like Pesticides and Arsenic and others from the water.
Does RO remove any useful minerals? If so, why should i purchase an RO system?
RO removes most of the minerals from the water; however the mineral content in water is much less than the mineral found in food. Minerals required by our body is derived mainly from food and less from water. For example, a 250 ml glass of milk contains more minerals than 20 litres of water. RO removes all objectionable minerals and chemicals from water which are responsible for the bad taste, saltiness & metallic taste in water. Reason, why Drinking water standards like USEPA has not set the lower limit of TDS (mineral salts) in drinking water.
Does a Zero–B RO kill or remove all bacteria & viruses present in water? Go to Top
The RO membrane has a pore size (.0001 micron) much smaller than bacteria virus, pyrogen or the Cryptosporidium parasite. Hence it will remove all microorganisms.
How does it differ from my existing UV water purifier?
Conventional water purifiers use a filter to separate out only the larger particles of dirt sediments from water.
UV systems use an ultra violet lamp to deactivate the bacteria & viruses present in the water without physically removing them. It does not alter the taste of water.
On the other hand, Reverse Osmosis not only removes suspended particles and microbiological organisms but also removes excessive salts, all harmful chemicals from raw tap water. Giving crisp, crystal clear double safe germ free water.What is the difference between Zero-B RO purifier and other competitors? Go to Top
Product comes from a company that leads the water treatment Industry in Indian since 40 years.
Product tested by leading laboratories in India for Microbial and chemical removal performance.
All products are backed by prompt & efficient after sales & service.Is RO water equivalent to distilled water?
Distilled water is boiled, and the steam is then condensed for drinking water. Distilled water contains practically no minerals or dissolved solids, whereas RO water does contain trace amount of minerals and salts. Most people report RO as tasting better than distilled water, which can taste flat. Distillers use high electricity, whereas ROs work on mini low power booster pumps or on line pressure from the household plumbing.
How is RO water different from mineral water? Go to Top
Mineral Water - Water which is first made absolutely free from minerals or salts. Thereafter, minerals or salts are added in required proportion for taste and to meet the drinking water standards.
RO Water can not be called mineral water because the salts or minerals are not dosed in it but are maintained by the rejection level of particular membrane.Can an RO purifier work on borewell water?
Yes, an RO purifier will work on borewell water with limits of the water as specified. The raw water should not have Iron, Manganese or Oil.
How much of raw water is required to make 5 liters of good water? Go to Top
About 15 – 20 of water is required to make 5 litres of pure water. Any RO purifier recovers about 25 – 30 % of the incoming water, the remaining impure water is rejected, it also keeps the membrane surface from too much salt build up and therefore gives better life of the membrane.
