The unique Conetrol <br /> SnorkelTm will hold free product at a precise level <br /> continuously for easy accommodation of most <br />' hydrocarbon recovery equipment <br /> Get enhanced treatment. <br />' <br /> Injected into the recirculation loop, air can be added to the <br /> extracted water at both the point of extraction and in the <br />' Centrxsep tank Volatile Organic Compounds (VOCs) <br /> begin to be stripped before entering downstream treatment <br /> in a ShallowTrayO low profile air stripper, giving an extra <br />' margin of performance safety <br /> Use it for enhanced pumping. <br /> The EconoPum jets draw a -27 H 68.6cm H <br /> P J " g ( g) vacuum <br /> and up to almost 2 cf n(3 4 m3/hr) at each well point By <br /> sealing the well and utilizing the vacuunn, more water is <br /> drawn into the well, measurably increasing recovery One <br /> documented site has more than doubled the yield by <br /> employing this pumping technique. <br /> Handles solids, iron, biofouling. <br /> The jets can handle particles 1/8" (3.2 mm) diameter while <br /> the Centrnsep tank protects the pump In addition, pumps <br /> are made with stainless steel impellers and diffusers, <br /> providing additional wear capacity against abrasives High <br /> velocity through the process loop provides little chance for <br /> iron or shme buildup, except when intentionally induced in <br /> the Centrisep tank <br /> Bonus features. <br /> The system can be used with any vapor extraction system <br /> and most phase-separated liquid recovery systems It may <br /> even be used with shallow wells less than one inch in <br /> I diameter Additionally, the EconoPump System provides a <br /> source of lugh pressure water which can be used for <br /> cleaning during maintenance <br /> ii 8/28/00 2 54 PM <br />
