Reverse osmosis is a technology that exploits the capacity of certain semi-permeable membranes to separate water from substances dissolved. Applying a certain pressure (that water network), the water is strengthened to cross the membrane; Pure water (permeated) will be thus divided by water containing salts (concentrate) The osmotic membrane that implements the most prompted level that is achievable (that of polyamide / polisulfone), behaves like a barrier towards not only of salts and inorganic substances, but also towards organic substances of molecular weight greater than 100; It is therefore an excellent defense against micro-increases, pesticides, pyrogens, viruses and bacteria that were contained in water. This technology appeared on the water treatment market in recent times, it came to rapidly stating, and, in a few years, it is imposed thanks to its characteristics of versatility, excellence of performance and ease of use.
• The membranes were tested at 25 °, 4.8 bar, 2000 ppm as TDS. • Due to the different operating conditions, compared to those ideal in which they were verified, real production is about half of the theoretical one.
Technical data Osmotic water - residual water The appliances were set to the ideal and experienced ratio of 1 to 4. Operating pressure 3 - 8 bar Temperature 1 - 30 degrees Celsius Quality membrane TFM Polyamide - Polisolfone Salt retention rate 98% - 99% Output water values 10 - 40 microsiemens
The OSMO50 plant consists of:
5 microns in-line sediment cartridge In-line coal cartridge treated with specific acids for water purification Osmotic membrane with a range of 50 gallons per day (1 gallon = 3.785 liters) Filter to delete NO3 PO4 SIO2 Attention to ...
Set the system always and only to a cold water pipe (at most 30 ° C) otherwise the consideration rate and the membrane can ruin before time. Check that the membrane is pushed well after all, before screwing the container cover (4). (The central membrane tube must be aligned with the edge of the container without a cover). Do not force the fittory (particularly the elbow connection - Flow Restrictor), but, if once started, the system showed losses, use the Teflon. Slide the water into the coal filter before connecting it to the membrane, so that it can purge any impurities present. Osmotic water and residual water must always be able to flow freely; Never close with taps or similar things. Protect the membrane from frost and drying. Once the membrane has been used it must no longer dry. If the reverse osmosis plant will not be used for more than 10-15 days, use a protective solution that makes the osmotic module efficient by inhibiting the growth of bacteria and preventing the depositing of impurities (Preservation Fluid). It is not possible with reverse osmosis to eliminate particularly high single values, for example a high content of silicic or nitrate anhydride. Do not leave the car unattended during use. Do not use water for food use. Always use original spare parts. Make regular changes from the pre-filter to sediments and the coal filter. The function of activated carbon is to retain chlorine that, if passes, irreparably damages the membrane torn the microstructure. The salts will not be retained optimally and the value in microsiemens, of the outgoing water will increase. Football and magnesium tend to settle within the membrane by decreasing productivity. Disinfection Powder Disinfects thoroughly and eliminates all scourts (impurities present) restoring the efficiency of the system. Very useful, for a correct management of the aquarium, it is Minerals that enriches osmotic water and all the very waters with mineral salts and trace elements. The permeate pH value is not predictable, high pH values can be easily correct down with CO2, if the pH value is too low, it is sufficient to air thoroughly obtained the water obtained.
Assembly instructions
1 water input from the water network
2 pre-filter to sedimentation
3 filter with activated carbon
4 Vessel - Membrane Container
5 Osmotic membrane
6 permeated - Osmotic water
7 Concentrated - waste water with flow restrictor valve
8 Anti-NO3-PO4-SIO2 filter
In our system the water enters the tap of the water network by means of the slip (connection located inside the sachet), reaches a universal fitting (1), and passes through a pre-filter to sedimentation (2) which holds particles greater than 0.005 mm (5 micron). (Only the RO Classic and RO NPS models have the sedimentation filter, in the RO Basic models the carbon filter also performs the 5-micron mechanical filter function). After this first purification the water is scrolled into a cartridge with activated carbon (3) That takes away the chlorine and also eliminates traces of pesticides, herbicides, metals and, even, the bad flavor and / or smell that water can free. After passing through the coal filter, the water is sent, under pressure, to a special membrane (5) that lets only pass pure water. The substances that harden water and harmful ones such as salts, carbonates, sulphates, heavy metals, pesticides, and even bacteria and viruses are retained and rinsed with residual water.
For assembly, the membrane must be inserted into its container by ensuring that the larger O-ring remains towards the cap, while the two small o-rings remain downwards.
To obtain the desired effect the quality of the osmotic membrane is decisive; The membranes used in our devices (polyamide / polisulfone) are extremely resistant to bacterial aggression, have long life, they are easy to preserve and remain unchanged for years. The water once treated, is pre-ducted into the central tube of the membrane and it comes out, pure, through the central duct (6). For the installation of the plant, open the water tap and rinse the appliance for at least two hours, during this period verified that in the channeling (7) will flow at least one quadruple quantity of concentrate with respect to osmotic water produced.
RO with anti-PO4-SIO2 filter:
If you have an osmosis system with anti-PO4-SiO2 filter, before connecting the osmotic water output to the anti-nitrate-phosphate-silicate filter (8), we recommend that you slide the water for about 2-3 hours so as to completely eliminate the Dry preservative of the membrane.
