New technology makes wastewater from the oilsands industry safer for fish

In the northeastern corner of Alberta, nestled among the expanses of forests and wetlands, lies a major freshwater dilemma that Canada is currently facing.

Just down the river from Fort McMurray, massive ponds stretch for miles, filled with toxic water.

For decades, the Canadian oilsands industry has been filling these ponds with wastewater from oil extraction. The purpose of these ponds is to store and reuse water, in order to reduce the amount of new water taken from the nearby Athabasca River.

The reuse of water for oil extraction causes tailings ponds to accumulate higher and higher concentrations of harmful contaminants. As such, the water in these tailings ponds is dangerous, and often lethal, to birds, fish, frogs and plants.

Currently, there is enough sludge-like water to fill half a million Olympic-sized swimming pools — and this volume continues to increase. This huge amount of wastewater has recently prompted Alberta

3 Big Dividend Stocks Yielding Over 13%; RBC Says ‘Buy’

After a four-month run of steady gains, September brought sudden, sharp, losses across the board. The NASDAQ, which peaked over 12,000 on September, has slipped just below 11,000, a loss of 9.4%, while the S&P 500 is down 6.7% in the same period. These are the deepest market losses since the crash of February/March earlier this year.The losses raise questions for would-be investors, most importantly, is this the start of another bear market, or just a correction before another run of gains? Whether this is an opportunity or the start of a bear, investors would be wise to take it as a warning. The bullish markets we’ve experienced this year will not last forever, and prudence would counsel taking steps to shore up the portfolio’s return potential. And that will lead investors into dividend stocks.RBC, the premier investment banking

Wastewater Treatment Technology Does Not Have to be New to be Disruptive

There has long been a recognition among waste professionals that waste should be seen and treated as a potential resource. Indeed, the development of a truly sustainable circular economy depends on it. With developments such as ZLD, the technology is now available to make such
societal changes a reality.

The term ‘disruptive technology’ can be found everywhere across the waste and wastewater treatment sectors, from conferences to whitepapers, from small industrial sites to large municipal wastewater treatment plants. There is no doubt that disruptive technologies have the power to transform sustainability in the waste sector, but it is important to realize that a technology does not need to be new in order to be disruptive. The widespread use of previously niche systems, or the novel use of well-established technologies like heat exchangers, can be equally transformative.
