RO 200 Series 20″ Filtration System

Through the connection, mains water first enters the pre-filter, which has 5-micron pores. The job of this high-tech filter is to remove coarse impurities in the water, that is, sediment such as dust, sand, algae and insects, down to 5 microns. Even after the sediment filter has captured suspended particles and bacteria larger than 5 microns and the water has become much clearer, it may still contain some microorganisms, dissolved chemicals and minerals.

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

Hyperfiltration, 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 such as lead, mercury, nitrate, arsenic and copper that may be dissolved in the water, as well as other chemicals or contaminants such as bacteria and limescale, have no chance of passing through this semi-permeable membrane, whose pores are about a millionth of a millimetre. 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. This filter's job is to remove odour-causing substances, 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 its alkaline pH raised, the water becomes rich in calcium, magnesium, sodium, potassium, iron, phosphorus and other minerals that nourish our bodies.
