Newer Member States, starting from a lower baseline, have also improved overall collection and treatment, despite lower compliance rates. This progress comes with significant EU investment support, amounting to EUR 14.3 billion between 2007-2013. Environment Commissioner Janez Potočnik ... | ||

Less and More: Why You Should Pump Slurries with a Peristaltic Pump
LESS WATERPeristaltic Pumps Use Less Water Hose pumps can circulate slurry SGs of 1.6 to 1.8 or up to 80% solid content. The traditional centrifugal pump loses efficiency when the slurry SG reaches 1.3 or 30% solids. With this limitation, slurry pumps have significant process water demands : on a plant processing 70 tonnes of ore per hour, every time a hose pump replaces a process slurry pump, it saves over 1,000 Million litres of water annually because of the slurry pump’s inefficiency : on the same duty, the hose pump requires less than ⅓ of the process water of a slurry pumpLESS ... | ||
