16. lding gasoline recovery projects where evaporation of the recovered product may exceed that of recovered product lf for some reason the P O D skimmer cannot be used in a particular well i e not enough well depth below the product water interface then the recommended skimmer is the FAP with the adjustable timer The FAP pump cycles to pump the product to the product storage tank regardless of the product level in the well By using the FAP adjustable timer the cycling time can be reduced from 10 12 cycles per minute standard FAP to a cycling time as slow as 1 cycle every 2 minutes This reduction in the cycle rate allows the free product to enter the well and increases the possibility that each dumping cycle would be full of product A disadvantage of using the FAP skimmer with the SolarNAPL is that the minimum air pressure to operate the pump is 60 psi This pressure would lift free product to over 120 vertical feet and will consume more volume of com pressed air than needed in any well that is less than 120 feet deep The FAP pump also requires the use of a coalescing filter regulator to remove moisture from the air supply because the on off cycle timer uses air logic 26
17. lly powered skimming systems the FAP and the P O D Pump On Demand Both can be used with the DGSI SolarNAPL however the P O D is first recommended for use with the SolarNAPL for the following reasons 1 Unlike the FAP the P O D skimming system only uses the stored compressed air when it has collected a volume of the skimmed free product 2 When the supply of compressed air has been shut off by the SolarNAPL s delay timer the P O D pump con tinues to collect free product until it is completely full When the delay timer is timed out and the air supply is returned to the P O D pump it will immediately pump the recovered productthat is stored in the pump to the product storage tank 3 Another important feature of the P O D pump that compliments its use with the SolarNAPL is that it can operate at pressures as low as 10 psi By supplying just enough air pressure to lift the product out of the recovery well and into the product storage tank the operator maximizes the stored energy of the compressed air that was produced by the SolarNAPL system This results in more product recovery and less run time for the compres sor additionally increasing the life expectancy of the air compressor 4 The P O D pump can accept wet liquid water in the air supply without damaging the pump 5 The P O D comes standard with a cycle counter that counts the pump cycle and thus indirectly the volume of recovered product This is important on slow yie
