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 ANVS® 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 first 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. The system can be used with 100% solar energy.

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

Our unit has been designed for continuous use. We recommend selecting the size of the unit based on locations estimated water consumption, in which case the interval for changing the pre-filters is planned according to assumed flow volumes.
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.
The SolarRO unit is manufactured from quality components in Finland, designed for durability and sustainability.

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

The unit is easy to maintain and you can do the maintenance yourself by following the manual instructions. The company has a technical support service team formed by the company's own engineers, also available for online and video training. We provide after-sales support, service, and training together with our local partners all over the world.
