Catching spills before they hit the ground will cut costs

The unintended underground of crisscrossed avenues provides an effective avenue for any seepage that “came down the crack” on the concrete slab. Releases of solvents and chemicals “eat away” at these between-slab expansion joints. As such, an annual inspection and recaulking may be a good investment.

Challenging wastewater lagoon cleanout for a remote Yukon community

There are no surface roads to Old Crow, located north of the Arctic Circle in Yukon Territory, so all equipment needed to be flown in. This provided a challenge as most dredges are too large to be transported by air.

Project delivery in the Arctic hasn’t changed much since the Klondike Gold Rush era

More than a century after what many consider to be the greatest “event” in the history of the Arctic, the Klondike Gold Rush, it is interesting to compare the delivery of projects during that era to today. Dawson City, and in fact much of the Arctic remains a project delivery challenge.

COVID variants detected in Wastewater prior to lab sequencing

In the new study, researchers sequence RNA extracted from wastewater samples, but there may be many different strains present because there are many individuals contributing to the sample. This makes it challenging to distinguish the SARS-CoV-2 genetic signal from the billions of bacteria and viruses people excrete every day.
iFILT – Diamond Filter

Innovative filter greatly reduces discharge of microplastics in wastewater effluent

The filter is based on a revolutionary fluid mechanics general concept. The basic idea is to combine an optimized fluid mechanics design with the cross-flow filtration process engineering approach.

How three municipalities are changing the game with level measurement technology

As radar technology has become more prolific, it has also become more affordable and cost-effective for wastewater treatment plants of any size. Operators need reliable measurements to keep pumps running smoothly, maintain inventory of important chemicals and additives, and measure how much water is moving through their facility.

Study identifies wastewater management strategy for western Saskatchewan

The design and construction of a wastewater management system includes two new sewage pumping stations; 32 kilometres of 100 mm, 200 mm and 250 mm high-density polyethylene wastewater forcemains; two new truck dump stations; a new booster station; and a new aerated lagoon to treat wastewater from the region.

Stripping ammonia from landfill leachate to produce hydrogen makes economic sense

Is it possible to turn landfill leachate from being a liability into an asset? Many minds have been exercised with this challenge but so far no one has broken through. Leachate remains a potentially troublesome problem with no clear route to becoming an asset.

Wastewater treatment plant installs prefabricated modular insulated floating tank cover system

As a result of increased demands on the 430 m³/day facility in St. Jacobs, Ont., upgrades were necessary for it to run as efficiently as possible with minimal downtime. It took only three days to install the panels of the prefabricated modular insulated floating cover system, while the plant was kept in operation
