FAQ's about Ultra Filtration?
What is ultra filtration (UF) membrane filter technology? Ultra filtration (UF) is used to remove essentially all colloidal particles (0.01 to 1.0 microns) from water and some of the largest dissolved contaminants. The pore size in a UF membrane is mainly responsible for determining the type and size of contaminants removed. In general, membrane pores range in size from 0.005 to 0.1 micron. UF membrane manufacturers classify each UF product as having a specific molecular weight cutoff (MWC), which is a rough measurement of the size of contaminants removed by a given UF membrane. A 100,000 MWC UF membrane means that when water containing a given standard compound with a molecular weight of around 100,000 Daltons is fed to the UF unit, nearly all of the compound will not pass through the membrane. Substances with a molecular weight of 100,000 Daltons have a size of about 0.05 microns to about 0.08 microns in diameter. UF membranes are used where essentially all colloidal particles (including most pathogenic organisms) must be removed, but most of the dissolved solids may pass through the membrane without causing problems downstream or in the finished water. UF will remove most turbidity from water.
Does your water purifier remove micro-organism from water? Most water purifier either kills or inactivate micro organism present in water by using chemicals or Ultra Violet radiation. Ultra filtration membrane filter micro-organisms including their floating dead bodies, cysts, and spores from your drinking water, by physically filtering them out through a membrane.
Does it remove turbidity from water? Water supply in monsoon is very turbid and water borne diseases are at its peak in monsoons. Membrane is the only method for removing turbidity from water. No other water purifying technology can boast of it but it never reduces TDS of Water.
Does it remove colloids from water? Colloids, which lead to dental problems, can be removed only Ultra filtration by membrane. Ultra filtration membrane is a membrane based water purifier.
Does it use electricity for purification? When you use Ultra Violet based water purifier, you have to depend on electricity. Ultra filtration membrane works on overhead tank pressure; so does not require electricity for purifying water.
Does it use any chemicals or additives for purification? When you use chemical filter, you consume extra iodine everyday which itself is a health hazard. Ultra filtration membrane does not use any chemicals for purifying water.
Does it have any operating cost? There is no operating cost on Ultra filtration membrane as it does not consume electricity but works on overhead tank pressure.
Does it have any maintenance cost? There are no electronics or mechanical parts in Ultra filtration membrane and hence maintenance cost is minimal. As it is easy to maintain, you do not need to enter into maintenance contracts.
Is your water purifier full proof? Does it give 100% pure water all the time? Ultra filtration membrane is full proof because water passes through a membrane whose pore size is so small that no bacteria or virus can pass through it. Till Ultra filtration membrane gives water, the water is 100% pure & safe.
Does your water taste natural after passing through your water purifier? Ultra filtration membrane works on the same principle used by nature to absorb purified water from dirty subsoil water e.g. Coconut water. Hence, water purified by ultra filtration membrane tastes natural.
Does your water look clear after passing through your water purifier? Water passing through membrane will look sparkling clear because it removes all colloids impurities from water.
Benefits of Ultra Filtration Systems 1. No need for chemicals (coagulants, flocculates, disinfectants, pH adjustment).
2. Size-exclusion filtration as opposed to media depth filtration.
3. Good and constant quality of the treated water in terms of particle and microbial removal.
4. Process and plant compactness and
5. Simple automation.
