Blue Spot Water purifiers/filters

What is the maintenance schedule of the purifier?

2009-08-12T06:08:00.000-07:00

Pre-filtration: Every 10 months
Membrane: Every third year (depending on the quality of the water source)
Taste and odour filter: Every year
Mineral injectors: Every year

What is the actual process of the Blue Spot Purifier?

Pre-Filtration
The source water is connected to the first 5 micron sediment filter which removes all particles that can be seen with the naked eye. From there the water flows to the second 1 micron filter called the granual activated carbon filter. This filter removes 99% of chlorine and lime in the water. After the granual activated carbon filter, the water flows through a third filter called the activated carbon block. This filter removes multi-chemical compounds, impurities and suspension.

Membrane
After pre-filtration, water is pushed through the Reverse Osmosis membrane. The membrane separates the total dissolved solids, viruses and bacteria from the water. The water concentrated with contaminants is flushed down the drain and the purified water is pumped into the 10litre reservoir.

Reservoir
The reservoir or tank has a bladder which expands as the purified water enters. When the tank is full, the process of purification stops completely. As soon as one opens the faucet, water will flow from the reservoir to the taste and odour filter.

Taste and odour filter
From the reservoir, water flows through the taste and odour filter. The function of the taste and odour filter is to remove all undesirable tastes and odours from the water. From the taste and odour filter, water is pushed into the mineral injectors/mineral stones.

Mineral injectors/Mineral Stones
The last two stages of the 7 stage system is the mineral injection phase. After the water runs through the membrane, it is absolutely pure. The two mineral stages introduce good minerals, which the body can use, back into the water.

The faucet
After the source water is pushed through all 7 stages, the purified water is dispensed through the modern design faucet.

Filter Replacements

It is essential to replace your filters at the right time to ensure effectiveness. If you do not change your first 3 filters every year your membrane will congest quickly (See picture above).
Standard filters for countertop, under counter, RO and most kitchen systems

Filter1: Polypropylene 10”

Filter 2: Granule Activated Carbon

Filter 3: Activated Carbon Block

Filter 4: RO Membrane 50GPD

Filter 5: Post Inline Carbon

Mineral Filters:Mineral Ball & Stone

What elements does the Reverse Osmosis Purifier remove?

What can be removed by Reverse Osmosis?

2009-08-12T05:58:00.000-07:00

The most important feature of this reverse osmosis system is its membrane. The membrane consists of several layers or sheets of film that are bonded together and rolled in a spiral configuration. The size of the membrane’s pores are 0,0001 of a micron. The material of the membrane is semi-permeable. This allows water molecules pass though while acting as a barrier to dissolved solids, viruses and bacteria. The remaining contaminants are concentrated and washed from the surface of the membrane down the drain.

What is Reverse Osmosis?

2009-08-12T05:57:00.000-07:00

Reverse Osmosis is the reversal of the natural flow of osmosis. In a water purification system, the goal is not to dilute a salt solution/contaminated water, but to separate the pure water from the salt and other contaminants. When the natural osmotic flow is reversed, water from the salt solution is forced through a membrane in the opposite direction by application of pressure, hence the term Reverse Osmosis.
