WATER PURIFICATION / RO SYSTEMS
Procuring pure water rests at the very baseline of success for the modern aquarist. It rises to this challenge with the conception of the Deluxe DOW RO water filter. Through sound component selection and optimization of contaminant extraction, Deluxe DOW RO units minimize energy use, water consumption and media replacement.
PURE WATER, TROUBLE FREE
The on-board microprocessor controller enables every Deluxe DOW RO unit to function with full automation. At set intervals, the unit will perform routine system backflushes, preserving the longevity of the membrane and efficiency. The unit is further featured with a shut-off solenoid which halts all water transit during instances of backpressure or loss of power to the controller.
MAXIMUM COMPATABILITY AND EFFICIENCY
Each Deluxe DOW RO system is furnished with a DOW HP-100 Booster Pump, enabling the setup to operate at the lowest source water pressures. By closely monitoring the water input, Deluxe DOW RO systems are amongst the most eco-friendly units, producing pure water with absolutely minimal waste.
This is the only proven way to take out the contaminants in your Town Water, Tank Water and Damn / Pond Water. For those that do not like Fluoride this is the only means of eliminating this additive in your Town Water.
Micro Computer Controlled for full automation, this is the main advantage over other system being currently sold. Added Value at no Extra Price.
The stages are as follows (please refer to attached diagram):
Reverse Osmosis Filter – This is for the RO desalting through and RO membrane.
In-line Granular Active Carbon Filter – this filter is for the removal of further taste and odor.
What is Reverse Osmosis?
Reverse osmosis (RO) is a separation process that uses pressure to force a solution through a membrane that retains the solute on one side and allows the pure solvent to pass to the other side. More formally, it is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure. This is the reverse of the normal osmosis process, which is the natural movement of solvent from an area of low solute concentration, through a membrane, to an area of high solute concentration when no external pressure is applied. The membrane here is semi permeable, meaning it allows the passage of solvent but not of solute.
The membranes used for reverse osmosis have a dense barrier layer in the polymer matrix where most separation occurs. In most cases the membrane is designed to allow only water to pass through this dense layer while preventing the passage of solutes (such as salt ions). This process requires that a high pressure be exerted on the high concentration side of the membrane, usually 2–17 bar (30–250 psi) for fresh and brackish water, and 40–70 bar (600–1000 psi) for seawater, which has around 24 bar (350 psi) natural osmotic pressure which must be overcome.
This process is best known for its use in desalination (removing the salt from sea water to get fresh water), but it has also been used to purify fresh water for medical, industrial and domestic applications since the early 1970s.
When two solutions with different concentrations of a solute are mixed, the total amount of solutes in the two solutions will be equally distributed in the total amount of solvent from the two solutions.
Instead of mixing the two solutions together, they can be put in two compartments where they are separated from each other by a semi permeable membrane. The semi permeable membrane does not allow the solutes to move from one compartment to the other, but allows the solvent to move. Since equilibrium cannot be achieved by the movement of solutes from the compartment with high solute concentration to the one with low solute concentration, it is instead achieved by the movement of the solvent from areas of low solute concentration to areas of high solute concentration. When the solvent moves away from low concentration areas, it causes these areas to become more concentrated. On the other side, when the solvent moves into areas of high concentration, solute concentration will decrease. This process is termed osmosis. The tendency for solvent to flow through the membrane can be expressed as "osmotic pressure", since it is analogous to flow caused by a pressure differential.
In reverse osmosis, in a similar setup as that in osmosis, pressure is applied to the compartment with high concentration. In this case, there are two forces influencing the movement of water: the pressure caused by the difference in solute concentration between the two compartments (the osmotic pressure) and the externally applied pressure.
Please refer to the Inorganic Contaminant Chart that is attached for what it does remove.
Please also refer to the following explanations to this chart.
The carbon pre-filter is omitted and cellulose triacetate membrane (CTA) is used. The CTA membrane is prone to rotting unless protected by the chlorinated water, while the TFC membrane is prone to breaking down under the influence of chlorine. In CTA systems, a carbon post-filter is needed to remove chlorine from the final product water.
Thin Film Composites
In the process of reverse osmosis, Thin film composite membranes (TFC or TFM) are used. Thin film composite membranes are semi permeable membranes manufactured principally for use in water purification or desalination systems. They also have use in chemical applications such as batteries and fuel cells. In essence, a TFC material is a molecular sieve constructed in the form of a film from two or more layered materials.
Membranes used in reverse osmosis are, in general, made out of polyimide, chosen primarily for its permeability to water and relative impermeability to various dissolved impurities including salt ions and other small molecules that cannot be filtered. Another example of a semi permeable membrane is dialysis tubing.
