Sewage

A new sensor system is designed to catch polluters, by sampling and analyzing water within the sewer line.

Recreational boaters looking to offload waste from sewage tanks can make a pit stop at pump-out stations on the marina, but there are also boats that can take away stored sewage. And the vessel recently delivered to Branford, Connecticut, is somewhat cleaner than most.

​When sewage sludge is processed at wastewater treatment plants, the leftover "biosolid" material is generally dried and set aside. While some of it ends up being used as fertilizer, much is often just stockpiled. Soon, however, it could find its way into eco-friendly fired-clay building bricks.

A system called the NEWgenerator is designed to help take the strain off sewage infrastructure in developing countries, acting as a mini wastewater treatment plant that recovers energy, clean water and fertilizer from sewage. Units will soon be installed in South Africa.

Researchers in Norway have combined the location services on smartphones with data from wastewater analysis to reveal a more accurate picture of the illicit drugs and pharmaceuticals taken in a community, even while traveling or commuting.

​When a virus is going around, the earlier it's detected, the better. It's with this in mind that scientists are proposing doing analyses of communities' wastewater to detect rises in the amount of viruses passed by residents, identifying the microbes based on their DNA.

A year after it first got under way, the first major work for London's Thames Tideway Tunnel "super sewer" project has been completed. A replacement pier at Blackfriars will provide continued access to river transport during work to reinforce the nearby river wall.

Global efforts to extract energy from sewage in forms such as heat, biogas and even electricity may get a boost thanks to the work of a team of biochemists and microbiologists from Ghent University, Belgium, who are collaborating on a pilot project with DC Water in Washington DC.

The US Department of Energy's Pacific Northwest National Laboratory (PNNL) has found a way to potentially change the 34 billion gal (128 billion liters) of raw sewage that Americans create every day into 30 million barrels of biocrude oil per year.

Researchers in Germany have developed a new method to harvest phosphorus, a key component of agricultural fertilizers, from wastewater. It incorporates a reactor that is environmentally-friendly, doesn't rely on chemicals, and is ready to be marketed.

London has embarked on what is described as a "one in one-hundred-and-fifty-year project." The maneuvering of a crane into place at Blackfriars on the River Thames marks the start of major work on the Thames Tideway Tunnel, a "super sewer" that will drastically reduce sewage overflow into the river.

Scientists from Houston's Rice University are looking into growing algae in municipal wastewater. The water would already contain its own free fertilizer, plus the algae would help clean it up.
