About Us


Rainter technology is different from other seawater desalination technologies. Our technology can convert seawater and other types of water into fresh, clean water. The energy conversion and water purification is based on physics and other other technologies are only able to desalinate seawater. The biggest difference between Rainter’s technology and other types of technology are that Rainter technology is able to remove all salinity from water, while other are unable to do so. As well as being able to treat seawater, Rainter technology can also be used to treat other types of water that have impurities, such as polluted river water, lake water and underground water. There are technological and commercial prospects using Rainter technology.

Technological development

  1. The development of marine seawater desalinator:

There are a large number of ships around the world and each of them have their own seawater desalination system. However, the water that is processed can only be used for non-potable purposes, such as cleaning and showering. This is due to its high impurity content while potable water should be supplied at ports. If marine units are developed, the amount of space on ships will be greatly increased and they will be able to stay out at sea for longer periods.

There are three different systems that can be used: a molecular vibration system, a steam recovery system, and a heat recovery system. The main treatment method is distillation, which is not easily installable in areas that are not unstable, as the spray that is produced is taken upwards due to steam that rises, which may pollute the steam. This means that it is difficult to install this type of system on board a ship. Our goal is to develop a unit that can treat seawater on board a ship. A solution has been put forward but time is needed for further testing.

  1. As the steam recovery system takes solar energy as its main heat source, illumination density is a crucial factor. R&D will focus on how to improve light to heat transfer efficiency as illumination density is weak at high latitudes.
  2. Reducing manufacturing costs:

There are three parts when it comes to calculating the costs: the purchase cost of the machine, energy consumption and consumable cost of machines, and the cost for the management and marketing of the machines’ operation. All components and parts are currently hand-made due to our relatively small production scale, so costs are still relatively high. Once improvements to the production scale have been made, the manufacturing costs of the units will reduce, and manufacturing moulds can be released for mass production in the future, so all manufacturing costs will be reduced.
