Dual-Phase Extraction System
Regardless of the vacuum blower chosen, a vapor liquid separator should always be installed inline prior to the blower to capture extracted liquid and minimize on liquid carry over to the blower inlet.
Vapor Liquid Separators are sized based on air flow rates and retention time. At a minimum the VLS should include an inlet filter, ambient air dilution valve with control valve, discharge demister element, discharge pump with controls, and instrumentation – vacuum / pressure / temperature gauges.
Dual Phase Extraction (also called Multi-Phase Extraction) is the use of high vacuum system to remove both contaminated groundwater and soil vapor.
MAE2 designs high vacuum systems with water and vapor treatment customized to your site needs. Combine Oil or Water Sealed Liquid Ring pumps for high vacuum and high flow, low maintenance rotary claw pumps for medium to high vacuum and high flow, or rotary lobe positive displacement pumps for low and medium vacuum and high flow with your choice of water and vapor treatment equipment.
The high vacuum dual phase extraction process involves the subsurface removal of air, water, and product. The main determining factor behind the selection of the high vacuum blower is the expected operating vacuum level. Rotary Claw blowers and Liquid ring pumps are most suitable for vacuum levels of 20-29 inches mercury (Hg). Each Dual Phase Extraction System is manufactured to meet your design and site requirements.
Corrugated Plate Oil Water Separators (OWS) are used to enhance the separation of petroleum and oils in free phase or dispersed non dissolved droplets from water.
Our lines of OWSs are manufactured to API 421 guidelines and each separator is customer designed to your specific application using a variety of separation media and material of construction.
Standard systems are constructed from marine grade aluminum or stainless steel with flow rates from 10-1000 GPM. Media options include PVC and Polypropylene style corrugated plate packs. Each separator is designed with universal fittings allowing the operator to remove and reinstall the lid to change the inlet/outlet orientation of the tank. Each OWS includes separation chamber, adjustable skimmer, overflow weir, pump out chamber, V Hopper, hinged gasketed lid, lid springs and standard inlet/outlet and drain fittings.
Custom separators can be built to your specification using a wide variety of materials and design options. A full 3 CAD drawing will be provided to you for approval prior to construction.
