If 40% hydrochloric acid is used, the weight loss must be less than 5% after 24 hours (Steel and McGhee, 1981). Friability: The sand to be used in the filters must be hard and robust. The formation of fine particles through attrition of the material should be min imized. Filters washing action can generate fine solids which lead to process ...

The company is looking for partners in the filter manufacturing arena to help it commercialize Perforene as a filter in the 2014-2015 time frame, he said. Lockheed officials see other applications for Perforene as well, from dialysis in healthcare to cleaning chemicals from the water used in hydraulic fracturing, or "fracking," of oil and ...

In March 2014, the Pagan Environmental Coalition of New York City (PEC-NYC) formed after being inspired to action by Gasland (2010), a documentary on the U.S. fracking industry. It became their mission to pro-actively promote the development of renewable, clean energy alternatives. In 2013, a group of U.K. Pagans held a ritual at Glastonbury Tor to raise awareness about fracking.
