Is the drinking water produced by the water purification unit as clean as tap water or bottled water?

Water produced with the SolarRO system has been certified as excellent quality drinking water according to the World Health Organization (WHO) standards.
Drinking water is tested in a laboratory that has International ISO/IEC 17025:2005 accreditation.
We use modern thin-film composite RO (Reverse Osmosis) membranes, which remove all impurities, bacteria, viruses and other contaminants from the feed water, leaving only high-quality water as the end product. Activated Carbon filter and the UV treatment at the end of the purification process give the drinking water a good taste and ensure its 100% disinfection.
The International Water Association (IWA) has declared that water treated by RO (Reverse Osmosis) method is pure, clean and healthy.

The drinking water produced by the SolarRO unit is just as clean as fresh tap water in Finland. It contains more of important minerals and less chlorine than normal municipal tap water. The quality of the water is the same as high-quality bottled mineral water. Outside Finland, bottled water is often made using the Reverse Osmosis method.

What is reverse osmosis technology?

Reverse Osmosis is a method that increases the pressure of untreated water to a level higher than its osmotic pressure. After this, the clean water molecules pass through a membrane. The membrane keeps all impurities, such as dissolved solids, chemical residues, bacteria, and viruses, on the other side.

Our unique patented technology creates constant pressure for reverse osmosis. Enabling you to make water with solar power without energy storage. All units can also be used with a hybrid power source.

How to use SolarRO unit?

The unit is easy to use. It has been tested and is ready to use when delivered from the factory. The filters are already installed. The end user only has to attach the inflow, outflow and production tubes to the unit using the clamps that come with the package. The pre-filter also has to be attached to the end of the tube and submersed in the source of untreated water. Once the unit has been plugged in, the system is ready to be turned on with the on/off switch.

How long can the SolarRO unit and filters be used safely?

Our unit has been designed for continuous use. It’s a good idea to select the size of the unit based on household water consumption, in which case the interval for changing the pre-filters is planned according to assumed flow volumes.
The SolarRO unit is manufactured from quality components in Finland, and it has two years guarantee. The interval for changing the filters varies according to the quality of the untreated water and hours of operation. On average, the filters should be changed 2–4 times per season.

How is the SolarRO unit maintained and where are spare parts available if needed?

The unit is easy to maintain and you can do maintenance yourself by following the instructions.
Spare parts are available from the manufacturer at a reasonable price. The unit is rain-resistant and made of sea aluminium. The membrane can be changed each year or stored over the winter in propylene glycol, which is siphoned into the unit with a pump. Glycol can be purchased from the manufacturer. The membrane is inexpensive, and it can also be changed the following summer.

All SolarRO components are tested and certified according to the highest international standards. We provide after-sales support, service and training with local partners all over the world.

Where are SolarRO products manufactured?

SolarRO units are designed and manufactured in Finland. Our revolutionary proprietary design is combined with the best modern components, pumps and technologies. All SolarRO components are tested and certified according to the highest international standards. One main design principle is that all components, filters and membranes, are very easily replaceable. Product research and testing have been done in close collaboration with Aalto University, the leading technology university in Finland.
