AQVA SAIMAA Reverse Osmosis System, 40 - 105 L/h pure water

Reverse osmosis assembly that produces 960 to 2520 liters of pure water per day from municipal, card-body, or lake water.

• Delivery/pick-up within 1-3 business days after the order.

• Orders can be placed online, via email, or by phone.

The reverse osmosis unit does not use electricity! Operates solely by the pressure of the pump or from any pressurized constant water supply. A unique valve solution automatically controls the unit. The amount of mechanical components is minimized, taking the system reliability into new level.

• It is enough to cover the water consumption of an average family, up to 6 family members or more.

• Also removes otherwise difficultly removable compounds such as uranium, arsenic, blue-green algae (99,9%), fluoride and chloride. Provides clear and clean water even from difficult water sources. The solids and organic matter content of the lake or river has some influence on the life span of the filters, but usually the prefilter is replaced once or twice a year and the osmosis membranes once a year.

• Includes three phase prefilter for solids, organic matter, smells and softening AQVA L-size filter set.

• Produces purified water, into a 185 liter tank, which is included in the package. Tank acts as an uninterrupted reservoir during the water consumption peaks. (other tank sizes and shapes available also)

• In the water tank the surface of the water is adjusted by the automatic float valve. When water is used, a water channel opens, whereby the reverse osmosis opens the water channels to keep the tank full.

• Water purification capacity at 4 bar, feed pressure, for example from a well or bore hole pump, is 2520 liters from fresh water in 24hours or 105 liters in a hour.

• Minimum recommended input water pressure 2 bar. Maximum input pressure 6bar.

• The package is not suitable for purifying seawater, but for the purification of moderately salty water yes. 

The system includes:

• AQVA RO-2 reverse osmosis unit (product code: AQRO-SA)

• Three-stage prefilter for solids, organic matter, smells and softening as AQVA L-size filter pack. (Product code for housings AQ3L)

• 185 liter water tank with the necessary tubing, fittings, valves and automatic filling valve. (product code: AQ-TAN-185)

• One micrometer air filter, to protect water tanks intake air quality (product code: AQMF1-M)

• Silent (47dB) distribution pump from water tank to consumption, Grundfoss constant pressure type. (Product Code: Scala2)

• Post filtering in the AQVA M-size enclosure (product code: AQUF01-M), which ensures the hygienic quality of the water taken from the water tank.

• A neutralization filter package that adjusts the pH to suit the water supply to the distribution network. Contains natural calcium. (product code: AQ1XL-PH)

• Couplings for connecting a reverse osmosis device to a prefilter and water tank

Typical annual operating costs arise from filter replacement. For example, with an annual usage of approximately 50,000 liters from a lake with a typical humus content (COD 30mg/l), the average operating cost is around €240.

Filters replaced every two years:

• Reverse osmosis membrane x 2, AQ061
• Post-mineralization filter, AQPH-XL
• Post-filter, AQUF01-M

Filters replaced annually:

• AQCB-L, AQPF-L

• AQMF1-L, a mechanical fine filter (€18.90), which may need to be replaced more frequently depending on sediment and suspended solids in the water.

Winter storage:

The reverse osmosis system can be stored in winter without additional valves by plugging the water lines with the plugs included with the unit and moving the system to a warm location. First, close the water line, drain the pipes and housings, then plug the system and store it in a warm place. This way, the membranes do not need to be removed. In spring, when bringing the system back into operation, you can run water through it for about 30 minutes to flush the membranes before use.
