Advantages of Reverse Osmosis

Water distribution companies are responsible for providing "potable" water, which means it must be safe and consumable.
However, this does not mean that it is suitable and safe for aquarium fish maintenance. In fact, the addition of chlorine or chloramine to our drinking water by water distribution companies can turn out to be
completely dangerous for our fish in some cases.
Water is probably the best solvent known to man. During the hydrological cycle, water can accumulate certain undesirable pollutants, among the most known are nitrates, phosphates, heavy metals
and hardness (an indicator of mineralization mainly due to calcium and magnesium ions). Each can be harmful to the fish and systems we strive to maintain. Reverse osmosis systems can remove up to 99% of these elements. All types of fish and aquatic systems will benefit from
the use of "osmosis" water. Not only for delicate freshwater species with low mineral content such as Discus (effect of reducing water hardness), but also for marine fish and invertebrates (reduction of nitrates
and heavy metals). All systems will benefit from the effect of reducing phosphate and nitrate levels, which are simply the main cause of nuisance algae in all aquatic systems.

Basic Principles

A reverse osmosis unit contains a tightly attached semi-permeable membrane. By applying osmotic pressure to tap water (the pressure must be a minimum of 2.7 bars) on one side of this membrane, pure water molecules pass through, while larger molecules such as nitrates and phosphates are filtered out. The result is a very pure softened water source (up to 99%) and water concentrated with waste. Osmosis water can actually be too pure for aquarium fish maintenance, as all beneficial natural mineral salts will have been removed. It is then important to recondition the water with appropriate treatment. Ask your specialized dealer for advice on available treatment and conditioning products.

INFORMATION

The infiltration flow rate is given based on standard test conditions and may vary depending on the quality of the feed water. Infiltration flow elements may vary by ± 30%.

NOTE

Upon startup, the water obtained after osmosis may contain elements of the preservation solution. It is necessary to discard the water obtained until the end of the first usage.

The unit comprises three sections (see diagram above). The central chamber membrane separates a sediment filter and an activated carbon filter on each side. Additionally, the unit is equipped with a flow regulator, which ensures a balance between the amount of filtered (usable) water and the amount of waste-concentrated water, thus providing the best conditions for membrane use. The membrane is supplied separately and must be installed before operation. The membrane is protected from moisture. This method is more advantageous than older methods of moisture preservation, allowing for longer storage and preventing damage caused by freezing in winter.

Filter

A sediment pre-filter and an activated carbon filter are provided as standard. The unit can be used regardless of the chlorine and sediment content of untreated water, and the unit produces water that meets European standards. Model – KBO50/75/100

Installation and Operation

Membrane Installation
1) Disconnect the hose from the membrane housing cap fitting. To do this, remove the small safety clip from the fitting and, while pressing on each side of the upper ring, pull out the hose.
2) Unscrew the membrane housing cap.
3) Install the membrane with the large rubber seal on top. Ensure that the other part is fully inserted into the socket at the end of the membrane housing.
4) Screw the membrane housing cap back on, reconnect the hose (this time without pressing the ring), and replace the safety clip on the fitting.

Unit Assembly

1) Remove the two mounting clips from the osmosis unit. Mount the clips on a sturdy vertical surface, facing each other, ensuring sufficient space (about 100 mm). Keep in mind that the unit will be heavier once filled with water during operation.
2) Engage the unit in the clips, ensuring that the membrane housing cap is in the highest possible position.
3) Measure the distance between the osmosis unit and the water supply faucet to which the osmosis unit will be connected. Cut the provided hose (3m) to the desired length. Do the same for the wastewater discharge hose and the osmosis water outlet hose to the appropriate container.
Note: The osmosis unit is sold with a standard 3/4" (20/27) fitting for a water supply connection to a garden-type faucet.

WARNING! The wastewater is highly concentrated with waste but can be collected and used for other purposes (ideal for watering plants, for example) but SHOULD NEVER BE INGESTED OR CONSUMED.

Starting the Unit

1) Slowly open the water supply and let the water flow through the unit. Check all connections and the unit’s tightness. HAND TIGHTEN any leaking connections if necessary.
2) Once the tightness has been tested, fully open the water supply faucet.
3) Let the unit run for an hour to clean the membrane of preserving agents and discard the collected water.
4) The unit is now operational.

Stopping the Unit

To stop the production of osmosis water, close the water supply faucet without allowing the membrane to dry out. Each time the unit is restarted, open the rinse valve (see diagram above) for 5 minutes. If the unit needs to be shut down for more than 7 days, it must be restarted and allowed to run for 30 minutes before collecting filtered water. If the unit needs to be shut down for a longer period, we strongly recommend connecting the discharge hose to the filtered water hose. This will prevent bacteria from entering the unit and allow it to remain water-filled, avoiding membrane drying. The unit should then be rinsed for at least two hours before being reinstalled.

Maintenance

Changing the carbon and sediment pre-filters.
The sediment pre-filter (part no. AVW013) and the carbon pre-filter (part no. AVW014) must be replaced every 6 to 12 months depending on the quality of the tap water. A significant drop in flow indicates that the pre-filters are clogged.
1) Turn off the water supply
2) Disconnect the hose from the pre-filter to be replaced and remove the pre-filter from the clips.
3) Remove the adapter hoses from the pre-filter to be replaced and install them on the new pre-filter. Teflon tape can be used for sealing the connections.
4) Reinstall the pre-filter in the clips on the unit and reconnect the hoses.

Replacing the membrane.

If a significant reduction of more than 50% in water flow persists after replacing the pre-filters, and provided there has been no other change in operating parameters (incoming water pressure, operating pressure, etc.), it may be necessary to replace the main membrane. Depending on the quality of the tap water, this replacement can occur between 6 months and 2 years, provided that the pre-filters have been replaced regularly.
1) Turn off the water supply
2) Disconnect the hose above the membrane housing.
3) Unscrew the membrane housing cover.
4) Carefully remove the used membrane from the housing, noting its position. If necessary, use pliers.
5) Lightly grease the two O-rings of the new membrane with silicone grease or an equivalent product. This will facilitate installation and promote a good seal separating the waste and the filtered water.
6) Install the new membrane with the wide rubber seal on top in the same position as the old membrane.
7) Reinstall the membrane housing cover and reconnect the hoses.
8) Reassemble the rest of the unit by following the initial installation instructions.
