Oasis Underbench RO with Booster Pump & Remineraliser

• A specially designed complete 6-stage reverse osmosis system for under-bench use.
• 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 unit comes complete, including all required connections, a 16L pressure tank, and a separate drinking water tap
• Oasis DP is specially designed for installation under the kitchen sink and comes complete with an installation kit.
• The unit is capable of producing up to 189 litres per day but in normal domestic installations with minimum pressure requirements being met, it can produce up to 90 litres per day approx.
• Designed in Italy, Assembled in Taiwan, with made in Italy Components

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,

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: 3-6 months. 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: 3-6 months.
• Max temperature: 45°C (113°F)

Stage 3: 5 Micron Carbon Block Filter/Purifier

• 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: 3-6 months.
• Max temperature: 45°C (113°F).

Stage 4: Reverse Osmosis Membrane

• 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: 3-6 months. Max temperature: 45°C (113°F).

Stage 6: Re-Mineralize

• 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: 3-6 months.

Tank Comes complete with plasteel tank 16 liters (4.2 gallons)
