Important Instructions

Reverse Osmosis Process

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, treated 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 do not get accumulated as in a traditional filter.

UV Process
The UV light has shorter wavelength (higher energy) than the visible light. It is called ultra-violet because it is just beyond the 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. Thus, they are essentially killed and cannot cause infection. This process of DNA modification is called inactivation.

Note: The purified water stored in the tank is disinfected using UV LED, which automatically switches on for 30 minutes in a two hour cycle.

Auto-flushing System

The purpose of the Auto-flushing system is to help prevent scaling or fouling of the RO membrane by providing a rapid rinse which washes away impurities from the membrane’s surface and keeps the membrane clean. It offers following benefits:

• Lowers rejected wateroutflow
• Improves “TDS” rejection rate i.e. increases the RO membrane’s efficiency
• Extends the life of the RO membrane

**Computer Controlled Operation

**

To ensure delivery of purer and healthier water, a micro-processor is installed in the purifier that performs the following functions:-
UV Stabilization Delay: To ensure that the UV lamp is pre-heated and is working at Its optimum level before it starts disinfecting water, the controller provides a two second delay to the UV lamp when the purifier is switched on. During this period. only the UV lamp is switched on and other electrical devices of the purifier are switched off.
Purification Delay: To ensure that the idle water lying in the internal pipes and in the UV chamber Is disinfected before being passed into the storage tank. the system provides a 5 second delay when the purifier is switched on. During this time, the UV lamp kills all micro-organisms that may be in the water inside the UV chamber. After this delay, all other electrical devices such as the booster pump and solenoid valve are switched on to start normal purification process.
Alarm: To ensure delivery of purer water, KENT Grand Stara Mineral RO’n Water Purifier in-built micro controller controls and senses various vitalcomponents anddisplays their statuson the digital Interface.

Automatic Operation

• The purifier automatically shuts off when the storage tank isfull
• The purifier does not start if the inlet water supply pressurefalls below 0.3kg/cm’
• The purifier automatically restarts when the water level drops below the maximum
• The purifier does not allow any water rejection in absence of electricity/when the tank is full
