The people of Sydney, Nova Scotia, Canada will now be able to finally enjoy more of their downtown as remediation of the Tar Ponds and Coke Ovens is now complete. The remedy was the largest contaminated site cleanup ever planned in Canada. The Tar Ponds and Coke Ovens are the result of over 100 years of steel production in the area. The contamination has had an environmental impact on about 100 hectares (274.1 acres) of land.
Proco Products, Inc. of Stockton, California was proud to be a part of the cleanup. Proco was able to supply (18) of our 900 mm ProFlex® 710/NN rubber duckbill check valves.
These were to be used as backflow preventers in the process to contain contaminants in cement on this project. The valves were provided with barnacle and algae resistant materials.
The ProFlex check valve will aid in making this space safe and beautiful for the people of Cape Breton to enjoy for many generations to come.
The ProFlex Duckbill valve is widely used as a perfect backflow device whenever there is a concern of possible backflow up a stream channel. In this project, the effluent was to flow out to the sea, but the customer did not want infiltration of salt water back into their work area. The ProFlex duckbill check valves that were supplied offer very low head cracking pressures and high back pressure capability. Another added benefit of using the ProFlex duckbill check valve in this application is its 35-50 years of service life.
