One of the biggest challenges in the water arena is lowering the cost of wastewater purification, which is a heavy consumer of energy. Israeli start-ups Diffusaire and Mapal have developed technologies which bring dramatic cost-savings to wastewater treatment facilities. (more…)

This is the second part of my blog on produced water (you can read the first part here) which will look at the market – the players and technologies – in some more detail.

Produced water is a term used to describe the wastewater that’s brought to the surface during the (more…)

The water industry is renowned for being risk averse and conservative. It’s understandable. No one wants people to experiment with their water.

But as fresh water becomes more and more precious and the cost of energy to get fresh water keeps on rising, the challenges of the water-energy nexus are (more…)

Water is one of the most exciting sectors at the moment in terms of cleantech innovation. The industry has a huge variety of investment opportunities but at Carbon International we focus on identifying the areas that we believe are the most exciting within broad industries such as this, and uncover the companies (more…)

Several global corporations have joined a World Resources Institute project that is developing a new database and mapping tools to help companies manage their water resources and reduce risk.

The Aqueduct project — which so far has enlisted companies such as Coca-Cola, General Electric, and (more…)

In a move to strengthen its position in water treatment, chemical giant BASF recently announced that it will acquire German water filtration membrane developer inge watertechnologies (inge).

Inge makes ultrafiltration systems used to treat drinking water, wastewater, and seawater (more…)

As soon as gas prices rise, our nation becomes focused on energy. When they drop again, it falls off most consumers’ radar. Yet the importance of energy goes way beyond the cost of filling up your gas tank or paying your electric bill. In often-extraordinary ways, energy is interwoven into absolutely everything (more…)

Natural gas is domestically abundant (2,587 trillion cubic feet of technically recoverable natural gas in the United States) and it burns cleaner than oil and coal (30% and 50% less carbon dioxide emissions respectively), but removing the hydrocarbons from mile deep shale beds has proven to be a dangerous and environmentally damaging endeavor. (more…)

If you’ve been searching for an environmentally friendly excuse to head to the pub for a pint, a group of scientists from Cornell University may be able to help. The scientists looked at over 400,000 gene sequences from brewery wastewater. Uncovered, were the genes of the microbes best suited to converting the wastewater into biofuel. (more…)

Energy Recovery Inc. (ERI), a company based in San Leandro, California, has developed technology that reduces the amount of energy required for desalination.

The technology does not directly relate to filtering water, but instead harnesses the pressure in the wastewater stream of reverse osmosis systems and transfers that pressure to the incoming feed stream to reduce the (more…)
