NET™ SYSTEMSUnique Bene? ts? Deploys in wells as small as 2 inches in diameter and to depths up to 200 feet below grade.? Can be integrated with a groundwater depression pump.? Installs ? ush-to-grade in traf? c areas.? Explosion-proof options available.? O & M costs are minimal.? Adapts to an in? nite range of water-table ? uctuations.? Telemetry packages are available for remote operation and maintenance.? Variable recovery rates range from less than 1 gallon per hour (gph) to greater than 100 gph.? Eliminates the need for groundwater or air permits compared to conventional recovery techniques.? Powered by electric, solar, hydraulic, wind , or hybrid energy.NET UNITL-NAPL and D-NAPL RemediationOur Contributions to the Environment • Optimize NAPL recovery• Increase recovery ef? ciency to 99% NAPL-water ratio• Reduce lifecycle costs by nearly 70%• Recycle to eliminate disposal costs• Eliminate perpetual liabilities• Use Green EnergyTHE INNOVATIONBased on extensive research and ? eld experience with petroleum and chemical spills, EIC has developed a simple yet practical solution to remediate both light and dense non aqueous phase liquids (LNAPL and DNAPL), also known as free phase product. The solution led to the development of a process which recovers primarily the NAPL thus eliminating the need to pump groundwater associated with conven-tional remedial techniques.The process, known as Non-aqueous Extraction Technique (NET™), utilizes an oleophilic/hydrophobic fabric capable of adsorbing the product with a 99% recovery ef? ciency. The fabric is conveyed in a continuous loop into the well to intercept the oil-water interface. As the fabric travels through the interface, NAPL is adsorbed. The adsorbed NAPL is removed in a specially designed desorption unit and grav-ity drained into a storage drum or tank. The recovered NAPL can be periodically transported to a recycle facility for reuse. The system can also be used to conduct recovery potential tests to determine if long-term recovery is sustainable. If sustainable, the system is capable of matching recovery to recharge in an in? nite range of water table ? uctuations. NET systems, therefore, eliminates perpetual liabilities. As an added value, the NET systems utilizes a fraction of the energy typically con-sumed by competing systems and produces minimial green house gases. The recovered product is typically recycled thus eliminating disposal costs.NET UNITHow NET Systems Work Squeeze-rollers in NET unit desorb the oil from the NET fabric. The oil gravity drains into a container.Weighted tail-pulley keeps the NET fabric taut and aligned in the wellOleophilic-hydrophobic NET bristles looped around the squeeze rollers (shown above) and the weighted pulley (shown below) continuously absorbs the NAPL present on the oil-water interface.
