Oasis DP-RO 6 Stage Under Sink Water Purifier System

Application

For an under-sink installation for designated purified drinking water. RO water is considered by many to be the best option for drinking water due to its purity, taste, and safety.

Enjoy pure, safe water with the re-mineralizing filter. This has many benefits such as improved Taste, Essential minerals, pH Balance, Electrolyte Balance, Protective Coating, and more that a 4 stage system doesn't offer.

Description

• The unit comes complete, including all required connections, a 16L pressure tank, and a separate drinking water tap
• A specially designed complete 6-stage reverse osmosis system for under bench use with mains pressure.
• This unit does an excellent job of eliminating undesirable contaminants, like Nitrate, Fluoride, and Salt. The remineralizing cartridge then puts beneficial minerals back in.
• The units membrane is capable of producing up to 189 litres per day but in normal domestic installations with minimum pressure requirements being met, it may only produce 1/2 of that which is sufficient for domestic installations.
• Because RO filtration is a slow process the water is stored in a pressure tank. 
• Designed in Italy, Assembled in Taiwan, with made in Italy Components

Environmentally Friendly

The Filter housings made in PET, a highly recyclable plastic, are manufactured with a proprietary procedure saving up to 60% of energy in injection molding compared with standard plastics. That is one of Atlas Filtri commitments to comply with Kyoto Treaty for the reduction of greenhouse gas (CO2) emissions in the atmosphere.

Test results of water quality after RO membrane (Remineralisation is added after the membrane)The membrane cannot differentiate between ‘good’ and ‘bad’ substances so it removes both

PH 5.5-6.5 
Water with a pH of 5.5-6.5 is mildly acidic, which is generally safe for drinking
Note: The re-mineralizing cartridge is designed to increase pH and reintroduce beneficial minerals like Calcium and Magnesium back into the water.

TDS 5-15 ppm:
A Total Dissolved Solids (TDS) measurement of 5-15 parts per million (ppm) is exceptionally low and typically considered excellent for drinking water quality.
Water with such a low TDS concentration generally tastes very pure and is often preferred for drinking. It indicates that the water has very few dissolved minerals, salts, and other contaminants, resulting in a clean and refreshing taste.

Calcium <2 ppm calcium concentration of less than 2 parts per million (ppm) in water is exceptionally low and typically considered excellent. Calcium is one of the minerals commonly found in water, and it contributes to water hardness. While calcium is an essential mineral for human health, excessively high levels of calcium in drinking water can contribute to water hardness, which may lead to scale buildup in pipes, appliances, and fixtures.
Having a calcium concentration of less than 2 ppm indicates very soft water, which is generally preferred for household use because it reduces the likelihood of scale buildup and may also provide a more refreshing taste. However, it's important to note that extremely low levels of calcium may not provide sufficient dietary intake of this essential mineral, so it's essential to consider overall dietary sources of calcium when evaluating water quality.
Note: The re-mineralizing cartridge is designed to reintroduce beneficial minerals like Calcium back into the water. 

Magnesium <1 ppm A magnesium concentration of less than 1 part per million (ppm) in water is also exceptionally low and generally considered excellent.
Similar to calcium, magnesium is a mineral commonly found in water and contributes to water hardness. While magnesium is also an essential mineral for human health, excessively high levels of magnesium in drinking water can contribute to water hardness and potential scale buildup issues.
Having a magnesium concentration of less than 1 ppm indicates very soft water, which, as mentioned earlier, is typically preferred for household use due to reduced scale buildup and potentially better taste.
Note: The re-mineralizing cartridge is designed to reintroduce beneficial minerals like magnesium back into the water. 

Sodium + Potassium <5 ppm Having a combined concentration of sodium and potassium of less than 5 ppm indicates very low levels of these minerals in water, which is typically considered beneficial for overall health, particularly for those who need to limit their sodium intake.
Water with such low concentrations of sodium and potassium is often preferred for drinking and cooking, as it contributes minimal additional sodium or potassium to the diet

 Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system

* Values are determined under the following conditions: temperature of supply water is 25 °C (77 °F), supply water quality and operation conditions correspond to manufacturer’s requirements.

Stages

Stage 1: 5 Micron Sediment Filter

PP Melt Blown Polyspun Sediment Filter

• The filter will remove sediment, rust and fine particles.
• This filter is designed to protect the remainder of the system from particles
• Life-span:  6 - 12months. Max temperature: 45°C (113°F).

Stage 2: Granular Activated Carbon Purifier

CTO, Chlorine, Taste and Odour Reduction

• This is a cartridge containing granular activated carbon to reduce chlorine (bad tastes, odours), herbicides, pesticides and traces of heavy metals.
• Life-span: 6-12 months.
• Max temperature: 45°C (113°F)

Stage 3: 5 Micron Carbon Block Filter/Purifier

Chlorine, Taste, Odour and Sediment Reduction

• This is an activated carbon block filter/purifier which will filter sediment, rust, and fine particles. It will also reduce chlorine (bad tastes, odours), herbicides, pesticides and traces of heavy metals.
• Life span: 6-12 months.
• Max temperature: 45°C (113°F).

Stage 4: Reverse Osmosis Membrane

Membrane for the main impurity removal

• The membrane has pores that are so small that only pure water makes it through to the other side, effectively removing undesirable contaminants like Nitrate, Fluoride, Arsenic, and Salt.
• Lifespan depends on the level of impurities in water and incoming pressure, but under normal circumstances, the membrane is expected to last 2-4 years.

Stage 5: Carbon Post Filter

• The carbon post filter’s main job is to give the water a final polish and improve the taste of the water after it has passed through the membrane and has been stored in the tank.
• Life span: 6-12 months. Max temperature: 45°C (113°F).

Stage 6: Re-Mineralise

• A remineralizer is generally used to add beneficial minerals back into water, particularly after a process like reverse osmosis which can remove most minerals. This can sometimes result in a slight increase in pH, making the water less acidic. However, the main purpose is not to reduce pH but to improve the mineral content and taste of the water.
• Life span: 6 months.
• Max temperature: 45°C (113°F).
