Trusted Drinking Water Treatment Supporting Prince Albert’s oil spill response

05/31/2017 | Municipal

In Canada’s central Saskatchewan community of Prince Albert, an oil spill in July 2016 tested the resilience of both the community and its drinking water treatment system. An estimated 200,000 to 250,000 litres of heavy oil and diluent leaked from a pipeline into the North Saskatchewan River 390 kilometres upstream of Prince Albert. Officials at the province’s Water Security Agency were concerned about the potential impact on the city’s drinking water, for which the river is the sole source. 

With several days before the plume would reach the city, Prince Albert’s public works team needed to quickly identify alternative sources of water.

Improving wastewater lagoon treatment in low temperatures

05/31/2017 | Municipal

The recent inclusion of ammonia as a deleterious pollutant from a regulatory perspective has created a challenge for municipalities to achieve final effluent discharge limits. The challenge to remove ammonia is elevated in passive treatment systems, such as aerated or facultative lagoons, where wastewater temperatures can reach as low as 0.5°C in the winter months.

Reclaimed Water Reduces Stress on Freshwater Supplies

04/18/2017 | Power

Meeting the needs of a planetary population expected to surpass eight billion people by 2025 is requiring more output from fewer resources. In the case of dwindling supplies of freshwater, the strain on the natural resource from economic and population growth, and climate change, can be exacerbated by other demands. One example: producing enough food for the growing population. Agriculture requires large quantities of water for irrigation and now claims close to 70% of all freshwater appropriated for human use.

Next Generation Thermal Hydrolysis Process - High Solids THP

03/23/2017 | Municipal

In short, thermal hydrolysis solves numerous challenges at a wastewater facility including increasing treatment capacity, reducing biosolids handling, increasing biogas production to reduce energy utilization, reduce operation cost for biosolids processing, produce renewable bio-fertilizer.

Effectively Using BAF Technology in Cold Climates for High Level Nitrogen, TSS Reduction

03/08/2017 | Municipal

The key distinguishing characteristic of the BAF process is that the microorganisms live in a biofilm attached to a media surface, rather than being freely suspended in the wastewater.

To The Last Drop

03/01/2017 | Mining

In the mining industry, water is used within a broad range of applications such as product handling, mineral processing, mineral extraction, dust control and amenities. But what happens if there is not a readily available supply?

Simple Yet Powerful

02/10/2017 | Municipal

New Discfilters have reduced power use at the Crown Point plant, saving the city about $70,000 a year. 

Perfect Purity

12/27/2016 | Oil & Gas

Pierre Frederic Diaz, Veolia Water Technologies, France, and Robert Wenta, Veolia water Technologies, USA, explain how the implementation of a new wastewater system helped to improve water quality and lower feedstock costs at the Petron Bataan Refinery in the Philippines.

Watering a Pearl in the Desert

12/27/2016 | Oil & Gas

Jeroen Boom and Joe Rehbein, Veolia Water Technologies, explain how a closed circuit zero liquid discharge system is used to recover, treat and reuse industrial process water at the Pearl GTL facility in Qatar.

Improving Effluent Total Nitrogen Using Advanced Dynamic Control of Aerobic/Anoxic Phasing

12/08/2016 | Municipal

As Process conditions are not constant, Fixed Phase Control cannot provide optimal process performance. Therefore, a Dynamic Phase Control strategy has been developed were phases are automatically adjusted as process conditions vary.

This paper presents results from the study of the Dynamic Phase Control strategy at the North Cary WRF, NC. The study showed that process can be significantly optimized by incorporation of Dynamic Phase Control.
