RO 300 Series 20″ Filtration System

Multi-Layer Hyper Filtration Technology

  1. 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 impurities, i.e. 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.

  2. 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 provides advanced filtration by filtering the water, already filtered to 5 microns by the sediment filter, to a precision of 1 micron.

  3. 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 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 membrane, whose pores are around one millionth of a millimetre. Only water molecules and the anions and cations beneficial to human health pass through this filter.

  4. Finally, on its way from the tank to the tap, the water reaches the alkaline filter, whose performance is doubled by using 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 its alkaline pH raised, the water is enriched with calcium, magnesium, sodium, potassium, iron, phosphorus and minerals that nourish our body.

Product description

In a staff tea kitchen, café or canteen, purified water is needed all day for drinking water, tea, coffee and ice; under-counter domestic units cannot keep up with this pace. The RO 300 Series 20″ is an electric reverse osmosis system developed for businesses, with a purification capacity of 900 litres a day.

Who is the RO 300 Series 20″ for?

For cafés, canteens, staff tea kitchens, offices, factories and construction sites. It can be used with mains, well and artesian water.

How does it work?

Water first passes through the filters in the 20″ housings: the 5-micron spun (sediment) filter traps sediment, mud and sand; the GAC carbon filter traps chlorine, unpleasant odours and organic compounds; and the carbon block (CTO) filter traps smaller particles and taste and odour problems. The pump then drives the water through the 3 × 100 GPD membranes. In the final stage, a coconut-shell post-carbon filter refines the taste of the water.

What does it offer in everyday use?

  • 900 litres of purified water a day
  • Less limescale and clearer aroma in tea and coffee machines
  • Clearer ice from ice machines
  • Can be connected to existing water dispensers
  • Quick and easy filter replacement

Installation, maintenance and warranty

The system is installed on your business's water line; an optional stainless steel tank can be added. The product is covered by a 2+8 year warranty. Contact us for capacity selection, installation and maintenance.
