A Solution for Wastewater Treatment Plant Stink

Posted April 14, 2017 12:00 AM by Engineering360 eNewsletter

A technique for identifying various odors at wastewater treatment plants, which run the gamut from burnt matches to rotten eggs, has been developed. Human panels and lab analysis of field samples are used to identify and control offensive scents. The researchers are working to refine and standardize the technology.

Have You Ever Peed in a Public Pool?

Researchers have determined how much urine is in a typical public pool by analyzing pool water for an artificial sweetener commonly found in human urine. In a large public pool containing 220,000 gallons of water (about a third the size of an Olympic pool) they estimated there are about 20 gallons of urine.

The study was carried out by researchers at the University of Alberta and was published Wednesday in Environmental Science & Technology Letters.

19% of adults have admitted to having urinated in a public swimming pool at least once, while 81% believe others have peed in a public swimming pool according to the Swimmer Hygiene Omnibus Survey [PDF] from 2012 by the Water Quality & Health Council.

Clean Water and Hydrogen from Wastewater

Posted February 21, 2017 12:00 AM by Engineering360 eNewsletter

Researchers at King Abdullah University of Science and Technology in Saudi Arabia developed a non-conductive polymer with a thin layer of platinum, allowing the coated fiber to act as a catalyst for the hydrogen-evolution reaction. They aim to address the problems of fresh water scarcity and energy security simultaneously by producing clean water and hydrogen from wastewater.

Wastewater Filtration Guidelines May Protect Aquatic Life

Posted January 09, 2017 12:00 AM by Engineering360 eNewsletter

University of British Columbia engineers developed recommendations for tailoring the design of specialized filters to local conditions to help prevent phosphorous deposit formation. If left unchecked, phosphorus can cause significant environmental damage and incur millions of dollars in additional maintenance costs for large wastewater plant operators.
