What is
the meaning of reverse osmosis?
Reverse
Osmosis is a water purification technology. The most common use of RO is to reduce the
water hardness and eliminate contaminants like Fluoride, Arsenic, Lead.
What is
the full form of RO?
Reverse Osmosis is
the full form of RO.
What is
the use of TDS in water purifier?
TDS full form is
Total dissolved solids. There is no use of it, it is simple a measure of
hardness. Water with the 500 mg/l TDS
value is considered as very hard.
What is
the meaning of RO in Hindi?
RO is acronym for Reverse Osmosis. 'R' from Reverse, 'O' from Osmosis.
'John' is a name in English, and it is same meaning in Hindi also John.
What is
RO MF?
MF is full form of Micro filtration purification technology. In MF
purification the water is passed through a special pore-sized membrane to
separate microorganisms. Both reverse osmosis and nano filtration are
fundamentally different since the flow goes against the concentration gradient.
In a recent research found that if MF filtration is used as pre-filtration, before RO purification, the purification results are much effective. Kent released such MF + RO purifiers in the market as well.

UF/MF as RO pre-treatment: the real benefit
Ultrafiltration (UF) and
microfiltration (MF) are theoretically the best pre-treatment upstream reverse
osmosis, removing from the feed water most of the potential elements
responsible of desalinating membranes fouling such as particles, turbidity,
bacteria and large molecular weight organic maters. Those clarification
membranes reduce also significantly the silt density index below 3 (100%) [1–6]
and generally below 2. Many papers present results about the efficiency of
UF/MF regarding clarification efficiency. UF/MF can be an economical option for
RO pre-treatment. Several evaluations of the cost of UF/MF upstream RO
demonstrate the interest of this pre-treatment technology on average to bad
water qualities, compared to a double filtration steps conventional
pre-treatment. In that case, and on a long-term operation basis, the treatment
line is economically viable [7]. However, UF/MF remains more costly than a
single filtration on mono or multimedia filter: UF/MF is not economically
applicable on the best water quality to pre-treat. Nevertheless, UF/MF
technology has some limits. If this technology is economically viable on
average to bad water qualities, UF/MF direct filtration can overpass the
technical limits of the process, generating the need of frequent cleanings. In
that case, the RO fouling is moved upstream to the pre-treatment stage.
Moreover, the clarification membranes, with cut off generally higher than
100,000 kd, do not remove the smaller organic matter molecules responsible of
the biofouling development on RO membranes. In this situation, it is very
difficult to demonstrate the real technical advantage of UF/MF on the RO
operation, since this demonstration needs a longterm study (more than one year
depending on the application) with side-by-side technologies to compare, and
the results appear to be site specific. Solution of this double problem, UF/MF
fouling on average to bad surface seawater and biodegradable organic matters
removal, can be found in the treatment line, enhancing the UF/MF treatment by
adding a precoagulation/settling of flotation. The benefits of this association
of technologies are multiples, as it was developed for the treatment on surface
water one decade ago for drinking water production. Moreover, the benefit of
the coagulation/separation on the design (filtration flux) and operation
(frequency of cleaning, membrane life duration) can significantly improve the
economical balance of the process. It also allows a definitive advantage.
