The futuristic KENT PRIDE MINERAL RO developed at KENT laboratory broadly comprises of
state-of-the-art RO+UF+TDS Control System. The initial purification by RO membrane having
porosity as fine as 0.0001 microns reduces even the dissolved impurities (hard salts, heavy
metals etc.). Double purification by UF membrane gives additional protection from deadly harmful
micro-organisms. Moreover, the patented TDS Control System intelligently retains essential
natural minerals in purified water, thus taking total care of your health and wellbeing.

UF Process
Ultra Filtration is a separation process that uses membranes with pore sizes in the range
of 0.1 to 0.01 micron. UF membranes reduce high molecular-weight substances, colloidal
materials, and organic and inorganic polymeric molecules including bacteria and viruses. Low
applied pressures are therefore sufficient to achieve high flux rates from an Ultra Filtration
membrane.
The Reverse Osmosis process, also known
as hyper filtration, is the finest filtration
process known till date. The process
ensures the reduction of particles as small
as ions from a solution. Reverse Osmosis
uses a semi-permeable membrane to
reduce salts from potable / brackish water.
In Reverse Osmosis, water pressure
applied to the concentrated side forces the
process of osmosis into reverse. Under
enough pressure, purer water is "squeezed" through the membrane from the concentrated side
to the diluted side. Salts dissolved in water as charged ions are repelled by the RO membrane.
The rejected impurities on the concentrated side of the membrane are washed away in a stream
of waste water and thus not get accumulated as in a traditional filter.

7. Before connecting the power supply, it is important that you perform the following
functions:
i Open the SS ball valve (Handle parallel to the ball valve) to start the flow of water into
the purifier.
ii Wait for 2-3 minutes to ensure that the filters are soaked in water.
White pipe is for raw water supply
5. Now connect one end of the white pipe to the SS
ball valve and other end to the lower pushfit elbow
fitting on the left hand side of the purifier labeled
as WATER IN.
Blue pipe is for reject water
6. Similarly, connect one end of the blue pipe to the
upper elbow fitting connector labeled as REJECT
WATER and leave the other end in the drain.
4. Connect the 3-way connector to the raw water supply as
shown in the figure. The threaded end of the 3-way connector
is fitted in line with the raw water supply. The other end
can be connected to a tap or can be plugged off if not
required.

Maintenance
TDS Adjustment*
Although the rejected water has high concentration of salts, it is absolutely clean and free of
impurities like chlorine, dirt, sand, etc. which are present in raw water. This rejected water usually
goes down the drain but if required, can be used for gardening purposes. It has high concentration
of salts and minerals which accelerate plant growth. Rejected water can also be used for cleaning
purposes, i.e. utensils cleaning, mopping, etc.

To ensure that the purifier operates at its BEST, a routine maintenance must be performed. The
frequency of the maintenance will greatly depend upon the raw water quality and consumption of
purified water.
The replacement time of consumables such as filters and membrane is dependent
on the quality of raw water and water consumed.

** Tested or certified flushing time - 24hrs.
Note: Filters and membrane are consumables. Their replacement time is dependent on the quality of raw
water and water consumption. They are not covered under the warranty. However, if a filter chokes within six
months and a membrane within a year, it will be cleaned/repaired/replaced free of cost. Changing the filters
and system inspection is available on call. The treatment capacity of RO membrane will reduce with time due
to clogging of pores of membranes.
“This reverse osmosis system contains a replaceable component critical to the efficiency of the system.
Replacement of the reverse osmosis component should be with one of identical specifications as defined by
the manufacturer, to ensure the same efficiency and contaminant reduction performance.”

“This system has been tested for the treatment of water containing pentavalent arsenic (also known as As (V), As

but may not remove other forms of arsenic. This system is to be used on water supplies containing detectable free
chlorine residual or on water supplies that have been demonstrated to contain only pentavalent arsenic.
Treatment with chloramines (combined chlorine) is not sufficient to ensure complete conversion of trivalent
arsenic to pentavalent arsenic. Please see the Arsenic Facts section of the performance data sheet for further
information”.
Arsenic Facts
Arsenic (As) is a naturally occurring contaminant found in many ground waters. It generally occurs in two forms
(valences or oxidation states): pentavalent arsenic (also known as As(V), As(+5), or arsenate) and trivalent
arsenic (also known as As(III), As(+3), or arsenite). In natural ground water, arsenic may exist as trivalent arsenic,
pentavalent arsenic, or a combination of both. Although both forms of arsenic are potentially harmful to
human health, trivalent arsenic is considered more harmful than pentavalent arsenic. More information about
arsenic and its toxicity can be found on the U.S. Environmental Protection Agency website at
http://www.epa.gov/safewater/arsenic.html.
This system is designed to remove only pentavalent arsenic. This treatment system does not provide a feature for
conversion of trivalent arsenic to pentavalent arsenic. The system may remove some trivalent arsenic, however, it
has not been evaluated for its ability to remove trivalent arsenic.
Trivalent arsenic is generally more difficult to remove from drinking water than pentavalent arsenic. Trivalent
arsenic can be converted to pentavalent arsenic in the presence of an effective oxidant such as free chlorine. The
arsenic in water containing detectable free chlorine or that has been treated with another effective oxidant will be in
the pentavalent arsenic form.4 Treatment with chloramine (combined chlorine) is not sufficient to ensure complete
conversion of trivalent arsenic to pentavalent arsenic.
Consumers using public water supplies can contact their utility to verify whether free chlorine treatment chemicals
are being used. Private water supplies and waters that do not have detectable free chlorine residuals should be
analyzed to determine the form(s) of arsenic present and the potential need for oxidation of trivalent arsenic to
pentavalent arsenic.
Arsenic does not generally impart color, taste, or smell to water, therefore, it can only be detected by a chemical
analytical test. Public water supplies are required to monitor treated water for total arsenic (trivalent arsenic plus
pentavalent arsenic) and the results are available to the public from the utility. Consumers using private water
sources will need to make arrangements for testing. A total arsenic test usually costs about $15-$30 and it is
recommended the test be conducted by a certified laboratory. Local health departments or environmental
protection agencies can help provide consumers with a list of certified laboratories. Some laboratories may also be
able to analyze specifically for (speciate) the form(s) of arsenic present in a water sample if requested.
This treatment system was tested under laboratory conditions as defined in NSF/ANSI 58 Drinking Water
Treatment Units – Health Effects and was found to reduce 0.30 mg/L of pentavalent arsenic in the test water to less
than 0.010 mg/L under standard testing conditions. Actual performance of the system may vary depending on
specific water quality conditions at the consumer's installation. Following installation of this system, the consumer
should have the treated water tested for total arsenic to verify arsenic reduction is being achieved and the system
is functioning properly.
The arsenic removal component of this system must be replaced at the end of its useful life of 1-2 years. The
