The Extran Ultrafiltration System (EUS) is a self-contained water filtration system designed specifically for the fluorescent penetrant inspection (FPI) process. The unique Extran ultrafiltration technology allows customers to effectively remove contamination so the clean water can be reused in the same inspection process or safely discharged into the sewer. Unlike most conventional systems, Extran's state-of-the-art membrane technology doesn't require membrane cleaning. The end result is a cleaner, more sustainable and efficient process that is low maintenance and uses only a small amount of consumables. The system can be used to remove a variety of contaminates such as oils, coolant, dyes and emulsifiers with fail-safe reliability, all while reducing wastewater volumes by 96% or more.
Advanced Hollow Fiber Membrane
The Extran Module is made with a proprietary cotton-based hydrophilic membrane. The left schematic shows the hollow-fiber membrane filtering contaminated water and separating it into two streams; a purified water stream that may be reused back into the process, while the other contaminated stream becomes more concentrated for disposal. This unique membrane has a very broad range of chemical compatibility and does not foul like conventional ultrafilters, which means Extran does not require any membrane cleaning. Most conventional ultrafiltration systems require a lot of maintenance and frequent membrane cleaning, generating too much chemical waste and making them difficult to operate.
Process
Polishing Skid
Water Polishing
The residual contamination and color can be further removed from the water by polishing with activated carbon, and optional polishing resin for recycling systems. Removing the large majority of the contaminants with the Extran membrane module substantially extends the life of the consumable polishing media. The polishing system includes wound fiberglass canisters containing polishing media. The tanks will be frame mounted and plumbed with isolation and sample valves. The number and size of the canisters will vary depending on the system and the needs of the customer.
Skim oil with less wastewater. SKIMZOIL combines and improves upon the best features found in conventional skimmers and coalescers.
The system is designed to skim and remove free-floating oils from washers, coolant tanks, and other sumps
Continuously skims the tank surface and circulates fluid through a separation tank
Free oil is trapped and automatically removed by a rotating skimmer drum
The drum design is very efficient at removing oil with very little water and cleaner
The clean water, without the floating oil, returns to the tank for reuse
The SKIMZOIL can also be incorporated into oil removal systems for pits and large tanks with free floating oil.
Separation Dynamics thoroughly evaluate your current FPI process to understand your wastewater and your goals for improvement. They then specify the best technology and system design to substantially reduce your waste. Separation Dynamics delivers a proposal that breaks down your investment, the operating costs, and how much you can benefit over time.
Separation Dynamics guides you through the implementation of your Extran water filtration system. These packaged systems are easy to install and integrate with your inspection process. Separation Dynamics provides on-site start-up assistance and training to help you seamlessly bring your system online.
Once your new system has been commissioned, it will be very simple to operate and maintain. Separation Dynamics continues to provide training, maintenance, and support to help ensure your investment pays off.
