Added profit for your solar electricity plant

You can increase competitiveness of solar electricity by adding revenue from desalinated or purified water at little extra cost.

Our MD cooling units will generate ultra pure water from any coolant stream.

  • No energy cost
  • Minimal maintenance cost
  • Long life
  • Cost per cubic meter of water
  • For Concentrated Solar Thermal
  • For concentrated Photovoltaics
  • For Photovoltaics 

Scarab Development AB has developed a method for water purification/desalination which can use cooling water or waste heat from solar power plants for the purification/desalination process. Hardly any running costs will be required and capital cost will be moderate. By adding value to solar electricity production, solar electricity plants will become more competitive. The technology is proven in other co-generation applications and will now be adapted in co-generation mode to solar electricity production.

Third party evaluation

Apart from our own continuous development work of which some is exemplified above, our equipment has been evaluated in the following third party tests:

Waste heat desalination - The Swedish National Development Corporation for the Greek Government

Ultra Pure Water and Reuse for the Semiconductor Industry – Sandia National Laboratories for EPA/Sematech

Decontamination of wash water in nuclear power plants - Pilot tests by Sydkraft (Eon) for Vattenfall and the Swedish Radiation Protection Institute

Energy use for MD water treatment in the Semiconductor Industry - The Royal Institute of Technology (KTH) for Xzero AB

Desalination with Solar Pond – U. of Texas at El Paso for the Bureau of Reclamation, US Department of the Interior

Some transformative thinking about the human environment

The Human Environment: In 1968, the Swedish government places an item called 'the human environment' on the agenda of the UN Economic and Social Council. This would eventually lead to the 1972 Stockholm Conference.

Laws of Ecology: Barry Commoner publishes the book The Closing Circle in 1971, where he suggests the four laws of ecology:

Everything is Connected to Everything Else. There is one ecosphere for all living organisms and what affects one, affects all.
Everything Must Go Somewhere. There is no 'waste' in nature and there is no “away” to which things can be thrown.
Nature Knows Best. Humankind has fashioned technology to improve upon nature, but such change in a natural system is, says Commoner, “likely to be detrimental to that system.”
There Is No Such Thing as a Free Lunch. Everything comes from something. There's no such thing as spontaneous existence.

Stockholm Conference: The United Nations Conference on the Human Environment is held in Stockholm, Sweden; it results in creation of the United Nations Environment Program (UNEP); Maurice Strong of Canada chairs the conference and will be appointed UNEP’s first Executive Director.

Blueprint for Survival: A manifesto signed by 36 of Britain’s leading thinkers is published in Teddy Goldsmith’s journal The Ecologist. The 'Blueprint for Survival,' warns of the 'breakdown of society and irreversible disruption of life-supporting systems on this planet'.

The Limits to Growth: The Club of Rome, a group of leaders and thinkers from 40 countries, issues the report The Limits to Growth written by Donella and Dennis Meadows. Based on a pioneering U.S. project of computerized global modeling, it argues that if present population, food, pollution, and resource trends continue, the limits to growth on the planet will be reached within the next 100 years.

Johannesburg Summit: 30 years later, in 2002, the Johannesburg Summit proved that until then international action had not been able to solve the social and environmental problems facing humanity. New paths must be broken and also business must be constructively involved.

There is enough for everyone: I eat fruit and greens from all over the world. I eat meat and fish from all over the world. I buy products manufactured all over the world made by raw materials from all over the world. I use energy extracted from all over the world. I spend vacations all over the world. I go to conferences all over the world. I drink wines and coffees and teas from all over the world.

At the same time, billions of people don’t have electricity and pure water where they live.

Things must change, and I know they will. There is enough for everyone’s need, but not for everyone’s greed. (Ghandi said that)

Scarab’s objective is to find business solutions to environmental challenges by developing innovative sustainable technologies and business.
