17 year old kid develops cheap way to make salt water potable

Why does scientists focus that much at that ten percent if we deal with the 90 percent?

This kid is amazing. The 17-year-old Chai developed a logic technology to turn salt water into fresh water.

Over 70 percent of the earth’s surface is covered with water, but only a fraction of it is fresh water. Scientists know how to get the salt out of seawater, but have so far not found an affordable way to do that inexpensive on a large scale.

Chaitanya Karamchedu seens to have the solution.

Trending: Sustainable Wastewater Reuse

Trending: Hydrovolta Sustainable Wastewater recycling system

Hydrovolta water recycling system

This trending wastewater reuse technology can reduce your water costs up to 95%.

It’s green, it is trending

The plug and play units will remove ions from industrial waste water by using the power of electricity (electrodialysis technology) and ultrasound as pre-treatment, with low pressure and energy, without using chemicals or high pressure osmosis.

It is supported by automatic regeneration of ions and self-cleaning filters and included with online water quality monitoring and telemetric control system.

Vacuum airlift for clean water

vacuum bio-cleaning

New Concept for Wastewater Treatment and Reuse

Coldep (France) developed this promising vacuum airlift technology which can move large volumes of water with a very low energy consumption. The only limitation of the system is its ability to lift water, with a maximum of fifty centimeters. And it’s all bio-cleaning. Read More

Drip irrigation’s compostable plastic pipes for sustainable agriculture

Israel’s turnaround came with a seven-year drought, one of the most severe to hit modern Israel, that began in 2005 and peaked in the winter of 2008 to 2009.

The country needed to introduce measures and become drought resistant.

Now, the country has enough water for people, industries and agri.

What did they do? Lessons learned from a country where every drop of water counts.

Textile industry can save 90% on water

Textile, jeans, wastewater, water recovering

Workers at a jeans factory must search through wastewater every morning to scoop out the stones, which are washed with the fabric in industrial washing machines to make stonewash denim.

With a new technique, the water consumption in the textile industry can be reduced to 90%.

Other benefits include are a lower energy consumption. For this application process, there are no adjustments required. Read More

Clean, phosphate-free water and recovering valuable nutrients

Struvite, wastewater, reuse, fertilizer, biological proces, footprint, nutrient, phosphate,

Alex Veltman with the result of the pilot production for struvite

Since the eighties, clean water plants in the Netherlands, remove phosphate and nitrogen from wastewater.

It’s a win-win situation.

  1. the nutrients can be used in fertilizers and bring money in
  2. it’s cleaner, phosphate-free water
  3. and it’s important to recover useful materials

The phosphate is found in the human (and animal) urine. Read More

Heat exchangers for the industry save 60% energy

wastewater, waste, heat exchange, climate change, co2, footprint, industry, carbon

Depending on the chosen system, up to 60% of savings can be achieved: in general a payback of between 1 and 5 years.

In industry, lots of hot water is used for cleaning. Hot water of 60 to 80 ° C is very common. During the industrial process a lot of heat flows directly with the wastewater into the sewer.

What a waste of energy! With Regain heat exchangers, heat can be recovered from wastewater. Read More

Wastewater is valuable

Biomass, waste water, value,

Valuable residuals are recovered from wastewater. Such as phosphorus and cellulose from wastewater and iron and calcium carbonate residuals from drinking water.

In several regions in Europe, waste water is recycled with renewable energy as a result.

Also valuable residuals are recovered, such as phosphorus and cellulose from wastewater and iron and calcium carbonate residuals from drinking water. 

This is done by using innovative concepts for (alternative) water supply, wastewater treatment and recovery of resources.  Read More

China invests in water treatment solutions

The environment is high on China’s political agenda. It’s all about 'war on water pollution'.

The environment is high on China’s political agenda. It’s all about ‘war on water pollution’.

The environment is high on China’s political agenda. It’s all about ‘war on pollution’. The message is clear: policies to tackle pollution and water scarcity will ‘spill over’ to impact industry. Financial analysts are trying to quantify the financial implications of these regulations. On the flip-side, there is increased interest in the water & wastewater treatment and waste-to-energy sectors.  Read More
