V2 KBO50 180L/day REVERSE OSMOSIS SYSTEM

KBO 50 REVERSE OSMOSIS SYSTEM from the brand Aquavie France, a leader in reverse osmosis systems. The KBO 50 model has a reverse osmosis water flow rate of 180 liters per day. Its performance is significantly superior to the competition, and all connection accessories are provided. These reverse osmosis systems are highly recommended!

Advantages of Reverse Osmosis

The water distribution companies have the responsibility to provide "drinkable" quality water, which means it must be safe and consumable quality.
This does not mean, however, that it is suitable and safe for maintaining aquarium fish. In fact, the addition of chlorine or chloramine to our drinking water by water distribution companies can prove 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 pollutants of undesirable qualities, among which the most well-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 mineralization 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 most significant nuisance cause linked to algae in all aquatic systems.

Basic Principles

In a reverse osmosis unit, there is a tightly attached semi-permeable membrane. By applying osmotic pressure to tap water (the pressure must be at least 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 prove to be too pure for maintaining aquarium fish, as all beneficial natural mineral salts will have been removed. It is then important to recondition the water with appropriate treatment. Ask your specialized retailer for advice on available treatment and conditioning products.

INFORMATION

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

NOTE

When starting up, the water obtained after osmosis may contain elements of the conservation solution. The obtained water should be discarded until the end of the first use.
Model – KBO50/75/100

The unit consists of three sections (see diagram above). The membrane, in the central chamber, separates a sediment filter and an activated carbon filter on each side. The unit is also equipped with a flow regulator, which balances the amount of filtered water (usable) and the amount of waste-concentrated water, thus ensuring optimal conditions for membrane use. Membrane The membrane is supplied separately and must be installed before operation. The membrane is protected from moisture. This method is more advantageous than older moisture preservation methods, 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 it produces water that meets European standards. Model – KBO50/75/100

Installation and Operation

Membrane Installation
1) Disconnect the tube from the membrane housing cap fitting. To do this, remove the small safety clip from the fitting, then press both sides of the upper ring and pull out the tube.
2) Unscrew the membrane housing cover.
3) Install the membrane with the large rubber seal on top. Ensure that the other part is fully seated in the socket at the bottom of the membrane housing.
4) Screw the membrane housing cover back on, reconnect the tube (this time without pressing the ring), and then replace the safety clip on the fitting.

Unit Assembly

1) Remove the two fixing 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, making sure that the membrane housing screw cap is in the highest possible position.
3) Measure the distance between the osmosis unit and the water inlet faucet to which the osmosis unit will be connected. Cut the provided tube (3m) to the desired length. Do the same for the wastewater discharge tube and the osmosis water outlet tube to the appropriate container.
Note: The osmosis unit comes with a standard 3/4" (20/27) fitting for connecting the water inlet to a garden-type faucet.

WARNING! The reject water is very concentrated in waste but can be collected for other uses (ideal for watering plants, for example) but MUST NOT BE INGESTED OR CONSUMED.
Model – KBO50/75/100

Starting the Unit

1) Slowly open the water inlet and allow water to circulate through the unit. Check all connections and the unit's tightness. Tighten BY HAND if necessary the leaking connections.
2) Once the tightness is tested, fully open the water inlet faucet.
3) Let the unit run for an hour to clean the membrane of preservatives and discard the collected water.
4) The unit is now operational.

Stopping the Unit

To stop the production of osmosis water, close the water inlet faucet without letting the membrane dry out. Each time you restart the unit, open the rinse valve (see diagram above) for 5 minutes. If the unit is to be stopped for more than 7 days, it must be restarted and run for 30 minutes before collecting the filtered water. If the unit is to be stopped for a longer period, we strongly recommend connecting the reject tube to the filtered water tube. This will prevent bacteria from entering the unit and will keep the unit filled with water, preventing the membrane from drying out. The unit must then be rinsed for at least two hours before being reinstalled.

Maintenance

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

Membrane Replacement

If a significant reduction of more than 50% in water flow persists after replacing the prefilters and provided that there has been no other change in operating parameters (inlet water pressure, operating pressure, etc.), it may be necessary to replace the main membrane. Depending on the quality of the tap water, this change may occur between 6 months and 2 years, provided that the prefilters 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 ensure a good seal separating the waste and filtered water.
6) Install the new membrane with the large 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 following the initial installation instructions.
