Sewage

Nitrogen and phosphorus are two of the key pollutants that have to be removed from sewage, and doing so typically involves two separate steps. Thanks to a newly-discovered bacterium, however, both could soon be removed at once.

A team from Australia's RMIT University says it's figured out a cost-effective way to produce hydrogen using wastewater and sewage. The process not only produces clean H2 gas, it also captures all the carbon in human poop and puts it to valuable use.

Scientists in Italy have uncovered evidence of the coronavirus appearing in sewage months before the country confirmed its first cases, a finding that may help them understand the origins of the virus and how it spread throughout the country.

Australian researchers are reporting a breakthrough in the battle against the novel coronavirus, discovering evidence of the virus in raw wastewater samples collected in the northern state of Queensland.

Scientists are pursuing some interesting technologies that could help us unlock the secrets of our sewage. Among them is a new type of “smart toilet” that automatically scans urine and stool samples for signs of disease.

There is an arm of science focused on revealing insights about public health by analyzing the contents of our sewage. And now one of the scientists on its cutting edge wants to use the technology to help monitor outbreaks of COVID-19.

Given the scarcity of fresh water in many regions, it does seem a bit crazy to be flushing the stuff down the toilet. And while a few coastal areas use seawater instead, doing so is problematic in its own way – new research, however, may change that.

In a way it seems so obvious: find out what kinds of things people are putting into their bodies by studying what comes out the other end. These do sound like muddy waters, but some see a very bright future for this dark corner of science.

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.
