TM

Presenting the Prime Mineral RO Water Purifier;
it uses futuristic and state-of-the-art technology to provide
purer & healthier drinking water.

TM

The heart of Prime Mineral RO Water Purifier is a
Reverse Osmosis membrane having capillaries as small as

0.0001 microns that reduces even dissolved impurities (salts
and heavy metals) and converts hard water to sweet and purer

TM

drinking water. Prime Mineral RO Water Purifier also
allows the user to control the Total Dissolved Solids (TDS) level
in purified water.

KENT is pleased to introduce Save Water Technology that helps you save and store water from KENT RO
Purifiers as well as from other RO purifiers.

As a part of Save Water Technology, KENT introduces RO Reject Water Storage Tank, which can be
purchased separately and then installed and connected to your KENT RO Purifier. This tank stores the
rejected water from the purifier, which can be used for washing utensils and mopping the floor. This unique
technology helps you recover more than 50% water, thus reducing wastage.

UV Process

The UV light has shorter wavelength (higher energy) than the visible light. It is called ultra-violet
because it is just beyond violet light in the light spectrum. Technically, the ultra-violet light is defined to
be any wavelength of light, which is shorter than 400 nanometer.

UV rays, which penetrate into the micro-organisms, are absorbed by the DNA of the pathogen in the
water. The DNA is altered in such a way that the pathogen cannot reproduce itself. Thus, it is
essentially killed and cannot cause infection. This process of DNA modification is called
inactivation.

Installation Instructions

UV Fail Alarm*

To ensure delivery of purer and healthier water, a micro-processor is installed in the purifier that performs the
following functions: -

UV Stabil ization Delay: To ensure that the UV lamp is pre-h eated and is working at its opti mum level before it
star ts disinf ecting water, the controller prov ides a two seconds delay to UV lamp when the purif ier is switched
on. During this peri od, only the UV lam p is switch ed on and other elect rical devic es o f the purifier are
switche d off.

Purifi cation Delay: To ensure that the idle water lying in the inter nal pipes and in the UV chamber is disinfe cted
before be ing passed in to the storage ta nk, the system pro vides 5 secon d delay when the pur ifier is switched
on. During thi s time, the UV lamp kills all micr o-organisms th at may be in the water insid e UV chambe r. After
this del ay, all other e lectrical devi ces such as boost er pump and so lenoid valve are switc hed on to star t
norma l purifica tion proces s.

The influent water to the system shall include no organic solvents, Chlorine <2 mg/L, pH 7-8, Iron <2mg/L, Turbidity
<1 NTU and hardness <1000mg/L

“This system is acceptable for treatment of influent concentrations of no more than 27 mg/L Nitrate and 3 mg/L
Nitrite (in combination measured as N), and is cer tified for nitrate/nitrite reduction only for water supplies with
pressure of 140 kpa ( 20 psi) or greater.”

This system has been tested for the treatment of water containing pentavalent arsenic (also known as As (V), As
(+5), or arsenate) at concentrations of 0.30 mg/L or less. This system reduces pentavalent arsenic 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 Ar senic 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 ar senic are potentially harmful to human
health, trivalent arsenic is considered more harmful than pentavalent arsenic. More information about arsenic and

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 cer tified laborator y. 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
