RNW 5300 Purified Water Dispenser

Through the connection, mains water first reaches the pre-filter with 5-micron pores. The job of this high-tech filter is to remove coarse contaminants from the water, that is, sediment such as dust, sand, algae and insects, down to 5 microns. Water that has been thoroughly clarified by the sediment filter, which traps suspended particles and bacteria larger than 5 microns, may still contain some microorganisms, dissolved chemicals and minerals.

The water then reaches the block carbon filter. The job of the block carbon filter is to remove organic matter that causes unpleasant taste, odour and colour, as well as chlorine and any gas odours present in the water. It makes the water tastier, clearer and odourless. It provides advanced filtration by filtering the water, already filtered down to 5 microns by the sediment filter, to a precision of 1 micron.

Hyper filtration, the heart of the system, has a semi-permeable membrane structure. It operates at a pressure of at least 2.5 atmospheres. Its pores measure between 8 and 10 angstroms. Heavy metals that may be dissolved in the water, such as lead, mercury, nitrate, arsenic and copper, as well as various chemicals or contaminants such as bacteria and limescale, have no chance of passing through the semi-permeable hyper filtration membrane, whose pores are as small as a millionth of a millimetre. Only water molecules and anions and cations beneficial to human health pass through this filter.

On its way from the tank to the tap, the water finally reaches the alkaline filter, whose performance is doubled by the use of ceramic and coconut shell, to gain flavour. The job of this filter is to remove substances that cause odour, prevent the formation of microorganisms and balance the pH of the drinking water between 8.5 and 9.0. Enriched with silver ions to improve its taste and with a raised alkaline pH level, the water becomes rich in calcium, magnesium, sodium, potassium, iron, phosphorus and minerals that nourish our bodies.
