The challenge in Air/Steam Stripper design was to develop a technology that could maintain high removal efficiencies with a minimum of residence time, at equivalent energy consumption levels to that of packed tower air strippers, while at the same time eliminating the maintenance factor. The TurboStripper® has been designed to meet these needs. It is an advanced leading technology for groundwater / wastewater cleanup. Responding to a long standing industry need for a 100% non-clogging Volatile Organic Compound (VOC) Air/Steam Stripper it represents a major breakthrough in ultra high-efficiency VOC stripping in a 100% non-clogging and space-saving design.
Turboid® TurboPak® is a patented process technology lying at the heart of the TurboStripperer® designs. Highly turbulent mixing and liquid shear is brought about in a liquid column by hollow media. The multiphase shearing forces lead to multiple contacts at the molecular level and provide enhanced interfacial area and mass or heat transfer coefficients.
There are hundreds of installations of the TurboStripper® technology around the globe.
The nature of the design provides highly turbulent, extremely efficient contact between the air/steam and the contaminated water that result not only in high efficiency VOC removal, but also guarantees plugging-free operation, even in the most fouling of environments. Traditional Air Stripping Towers are limited by their available surface area for mass transfer, by plugging from solids deposition & precipitation & by flooding at high gas or liquid velocities.
The TurboStripper®’s fluidized bed elements are continually moving and violently participating in a three phase turbulent interaction of Turboid®, Air/Steam and Contaminated Water. One of the many benefits produced by the shearing action of the Turboid®, is that bed scaling deposits are prevented from building up on the packing; thus creating a completely Non-Clogging Air or Steam Stripper.
The TurboStripper® can, in addition to removal dissolved gases can recover a large portion of the latent & sensible heat (or energy) content of the liquid stream which can be employed elsewhere on the plant. The high heat transfer coefficients produced ensures that the maximum amount of heat which is possible to recover is recovered.
Unlike any conventional tray type or packed tower air stripper, the TurboStripper® will remove most of the highly soluble chemicals such as MTBE, Acetone, MEK etc, all without fouling. The controlled turbulence within the fluidized bed effectively increases the interfacial area (IA) equivalent to ten times that of the Turboid® packing surface. The rapid shearing actions generated by both the air and water also naturally enhance the side turbulent diffusion mass transfer, thereby increasing the mass transfer coefficient (K). The combined effect of the increase in both IA and K, minimizes TurboStripper® size and maximizes stripping efficiency!
