The Department of Energy (DOE) is funding a demonstration project that remediates acid mine drainage water, providing both source water and useful byproducts for hydraulic fracturing operations.
Speaking on the state of the challenging water/wastewater treatment market — hampered in recent years by slow municipal growth — Heiner Markhoff, a leading voice in the water treatment technology market, sees “light at the end of the tunnel.” Find out why in this exclusive Q&A with Water Online.
There are few topics more controversial these days than hydraulic fracturing ("fracking"). While the debate rages on as to whether fracking poses a risk to water quality, a new desalination technique addresses two other environmental concerns: water scarcity and greenhouse gas (GHG) emissions. Developed by researchers at the University of British Columbia (UBC), the breakthrough technology uses excess carbon dioxide created in the fracking process to desalinate the process water, making it available for water reuse. It also generates chemicals — hydrochloric acid and carbonate salts — that are valuable for many industrial applications.
Selecting the proper flow meter will take an operator through a fairly typical vetting process, including consideration of capital expenditure (CAPEX), O&M requirements, effectiveness, and durability. Manufacturers of all meter types (e.g., Venturi meters, magnetic flow meters (magmeters), cone meters, etc.) will surely claim to excel in these categories, but can they back up the claim?
