Rivers of Fresh water using Desalination on Solar Power

solar power, fresh water, technology, desalination, water risk, california, brazil

The heat is fed to a multi-effect distillation system that evaporates freshwater from the source water being treated and can handle varying quality up to 100,000 ppm TDS

Can this modular, solar-thermal water system deliver enough water for dry California? WaterFX says it does. Their Aqua4to treats and desalinates generates 65,000 gallons of freshwater per day, from:

  • wastewater
  • drainage water
  • runoff
  • saline groundwater
  • industrial process water

A floating ball cover providing algae control and saving water by evaporation control

With the California drought; evaporation continues at an alarming rate while precipitation fails to fall, leaving above ground reservoirs dangerously low and groundwater reservoirs pumped dry, while California’s water demand remains insatiable.

What about the water that’s already there? What about the water that is destined to evaporate? Why don’t we cover the reservoirs? Read More

Costs of sea water desalination are going down

Desalination, fresh water, drinking water, sea water, reverse osmosis, climate change

With Memstill, it is possible to desalinate a cubic meter of drinking water for 0.50 Euro cents from seawater.

Less water is always the best option.

But in case of a shortage of fresh water, nowadays the preparation of drinking water from seawater is a great alternative.

And the costs of sea water desalination are going down.

Thermal desalination has been overtaken by reverse osmosis and that led to some major changes:

  • the proces is much cheaper
  • the energy consumption during the proces has decreased sharply

Schools use cleaned rainwater for toilets

Schools harvest rainwater for their toilets

For buildings where a lot of water is used: like schools, sports centers, offices and public buildings, there is a huge advantage of harnessing and reusing the rainwater.

Preventing that rainwater is wasted, has becoming increasingly important. Climate change ensures it gets warmer, and we will frequently will be surprised by sharp downpours like the warm monsoons in Asia.

Aquaflow has designed a system that collects the rain water so that it can be reused as clean toilet flushing water. A school in the Netherlands has been reusing this ‘grey’ water since 2013 and is still very pleased with the clean toilet water. Moreover, the sustainable infrastructure approach of the school is an example for children and their parents. Read More

Your green world: contribute to this vessel cleans rivers and canals

plastic soup cleaning vessel

Contrary to the commonly-held belief that plastic takes 500 to 1,000 years to decomposes, researchers now report that the hard plastic polystyrene begins to break down in the ocean within one year, releasing potentially toxic bisphenol A (BPA) and other chemicals into the water…”

Entrepreneur De Waard started the Foundation SarasWater and now introduces a vessel that cleans rivers and canals from plastics. While snorkeling on vacation, he was astonished by the amount of plastics in the water.

The Foundation needs 20,000 euros to develop a prototype which can catch plastic particles to 2 millimeters to big parts.

The Oceans CleanUp! Remarkable Project

The Oceans CleanUp! Remarkable Project

Plastic soup

I have to thank Torbjørn Johnsen, from Sweden, for sending me the information about this Oceans CleanUp concept; in response to one of my discussions. I thought this is an effort worthy of sharing this info, spread this around as much as possible, so I decided to post it as a discussion.

I think that, by sharing it, it will encourage readers to share their thoughts, offer their input, perhaps pass it on to others. That is the idea. Sea how a young guy want to clean the oceans.


VIDEO Oceans CleanUp concept

Boyan Slat about the Oceans CleanUp concept

The thought come to mind that “if a young man found the way, by designing a system to clean up the oceans, why can’t governments around the world can’t do the same, or even more? Projects such as this, are what I expect environmental protection agencies be doing. At least, I hope that they can provide support to it. You will find more information here.

I would love to see this project grow, supported by every country, because the ‘union rises the power.’

That is exactly what humans need to do: i.e. come together to ensure our planet’s sustainability; this is the only vessel within the universe we know, that can offer humans the exact, perfect settings for us to carry out moving our civilization forward…even we may discover life somewhere else, at another planet, we can’t never be sure it would suitable for us to survive in the very comfortable way we do here on earth.

Flood risk: Hansje Brinker (Netherlands) plugged with his finger a leak in a dike.

A world-famous story about The Netherlands and water management is about a boy who plugged with his finger a leak in a dike. Indeed; Hans Brinker. Well, here is probably news for you: Hans Brinker never existed.

The story is folklore, especially for people outside The Netherlands.

Amongst themselves the Dutch don’t tell fairytales about water management, that serious is the subject for my fellow country(wo)men and me. One mistake and half of our nation is swallowed by sea and rivers. Knowing this, it wouldn’t surprise you that water management, for the Dutch, is something for professionals. Until… Read More

Fresh drinking water from the sea using solar

Solar cells can supply the heat energy to the ORC, which then produces mechanical energy to pressurise the water.

Solar cells can supply the heat energy to the Organic Rankine Cycle, which then produces mechanical energy to pressurise the water.

One of the main ways to obtain drinking water in hot, dry countries bordered to the sea is through desalination.

European researchers developed a high-efficiency and low-cost desalination technology by exploiting solar energy.

Solar desalination evaporation is used by nature to produce rain which is the main source of fresh water on earth. This new distillation system is a duplication on a small scale of this natural process.

Clean-up plastic soup in the oceans

Boyan Slat – Dutch student from Delft – presents his solution to the plastic soup: the millions of tons of waste plastic floating in the water and come together in five places in the ocean currents cunning.

Boyan Slat extracts 7,250.000 tons of plastic out of the oceans with this innovation

Boyan Slat extracts 7,250.000 tons of plastic out of the oceans with this innovation in 5 years.

Slat devised a receiving station with large floating arms that separates the plastic from living organisms and captures.

Thereafter, the waste can be recycled.

The station is a permanent place in the sea. The rotating flow pushes the plastic inside.

UNEP (the environmental organization of the United Nations) estimates the amount of plastic in the oceans at 44 million.

Each year the soup grows with 5 million tons of plastic.

The clean-up of Slat seems like a monumental undertaking. But Slat is not alone. More and more organizations are hard on small and large scale clean up the plastic waste. For example ‘The Plastic Whale‘ from Marius Smit who made a boat out of plastic bottles in Amsterdam.

Slat is developing technologies to preventable, intercept and extract oceanic plastic pollution.
Currently they are investigating the feasibility and viability of The Ocean Cleanup Array, as a passive and large-scale method of remediating world’s gyres.

The plastic soup consists large pieces of plastic, but also micro plastic.

Because it consists of a variety of sizes, it poses a threat to a large part of the animals that live in the sea.

The large pieces of plastic pose a threat because larger (mammalian) animal managed to get stuck and thus drown or suffocate.

Animals think the small pieces is food so it ends in their stomachs.
