New technology water purification created

As part of their ongoing commercialization phase, they might want to consider some more market-friendly name for their process than "aerobic granular sludge technology."

Delft University of Technology researchers, in partnership with DHV Engineering, have developed a compact and environmentally friendly purification method, in which aerobic bacteria form granules that sink quickly.

With the new aerobic granular sludge technology, aerobic bacterial granules are formed in the water that is to be purified. The great advantage of the granules is that they sink quickly and that all the required biological purifying processes occur within the granules.

The new technology purification system needs only a quarter of the space required by conventional installations and uses 30 percent less energy.

The aerobic granular sludge technology, now in its commercialization phase, has been nominated for the Dutch Process Innovation Award of 2006.

1. That is cool. I'm going to confess to being very interesting in how

sewage is processed.

No one likes to think about this processing, but it is very important, and has huge environmental implications. I have spent many hours daydreaming about supercritical water oxidation of sewage sludge.

I hope this thing can be made to work on scale.

4. It's OK N

You're not the only one interested in sewage technology. It's actually quite interesting. In a prior life, I worked as an industrial hygienist, mostly observing people removing asbestos and lead. One of our jobs was at an old water (not wastewater) treatment plant in DC. The filter rooms there, built during the CCC days, were befitting of a ballroom: we were removing the decorative (asbestos) plaster columns over the steel girders. Before the remediation, those rooms were beatiful, empty, cool, and serene. The sand & charcoal filter beds were in pools in the tile floors, and surrounded by brass railings. After the remediation, they were still nice, but not nearly as elegant.

5. It may not be sexy, but it sure is important.

Prior to modern sewage systems, cities were pretty foul places to live. And that was before there were cities with 10 million people.

6. Can you imagine the cholera, in an unsewered city of 10 million?

I suspect that cholera will be one of the first symptoms of system collapse.

7. Ugh. I suppose New Orleans was a preview.

8. I actually don't recall disease outbreaks in that time.

Of course, much about that case remains hidden, and what was not hidden is already forgotten.

9. There were no widespread outbreaks...

but various people did come down with some nasty water-born bugs, especially those who were forced to drink the polluted floodwater to survive. Because the Mighty Superpower couldn't be bothered to rescue its own citizens in a timely and organized manner. Or spend the money to build proper levies in the first place.

11. I would bet that there would be all sorts of interesting epidemiological

epidemiological outcomes from those flood waters, except that no one will look for them.

In a way, it's almost too bad that nothing happened as a result of Katrina at the Waterford Nuclear Station. The world would be all over the case if something happened at Waterford.

12. Is that the same thing as super concentrated water oxidation?

I ran that as a debate case in HS and cleaned up with it. :evilgrin:

3. ANGST--Aerobic Newfangled Granular Sludge Technology.

Too 20th century sounding, maybe?
