AquaSep EL Coalescers Filters
Product Details:
Pall’s new AquaSep EL liquid/liquid coalescer system is a lower cost solution to separate higher solids and medium to coarse emulsions versus competitive cartridge coalescers, mesh pack coalescers, sand beds and electrostatic precipitators (ESPs). Its cost effectiveness is due to the ability of each coalescer element to process a higher flow in a higher solids environment while still providing superior effluent quality. For existing cartridge coalescer systems, the AquaSep EL element provides superior continuous removal of liquid contaminant thereby making it a more reliable solution than competitive offerings.

Not all coalescers provide a high quantitative removal of dispersed liquid contaminants and can handle emulsions with low interfacial tensions (IFTs). For example, conventional cartridge and mesh pack coalescers made of glass fiber media begin to lose efficiency when the IFT of the emulsion gets below 20 dynes/cm. In contrast, the new AquaSep EL coalescer from Pall is constructed of a high-efficiency, polymeric medium, making it well suited for numerous liquid/liquid separation applications with very low IFTs including: • Water removal from hydrocarbon condensates before stabilization, fractionation or pipeline transport • Removal of oil from sour water to protect sour water stripping (SWS) as well as downstream sulfur plant and water treatment operations
