RNW-A2O Wall-Mounted Water Dispenser

Through the connection, mains water first reaches the pre-filter, which has 5-micron pores. The job of this high-tech filter is to remove coarse contaminants in the water, i.e. sediment such as dust, sand, algae and insects, down to 5 microns. Even after being thoroughly clarified by the sediment filter, which captures suspended particles and bacteria larger than 5 microns, the water 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 bad taste, odour and colour, as well as chlorine in the water and any gaseous odours. It makes the water better tasting, 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 are between 8 and 10 angstroms. Heavy metals such as lead, mercury, nitrate, arsenic and copper that may be dissolved in the water, as well as bacteria, limescale and other chemicals or contaminants, have no chance of passing through the semi-permeable membrane, whose pores are a millionth of a millimetre in size. Only water molecules and anions and cations beneficial to human health pass through this filter.

Finally, on its way from the tank to the tap, the water 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 odour-causing substances, prevent the growth 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 other minerals that nourish our bodies.
