FAQ: EDI Membranes & Aeration Systems
Which EDI membrane material should I use?
- EPDM and PU offer good general-purpose performance; Matrix™ and Matrix Plus™ are best for high-fouling or high-temperature systems. Multimaterial listings are available.
Can EDI diffusers be changed without draining the tank?
- With ModuleAir™ retrievable configurations, yes—grids can be lifted out while the system remains online.
Are EDI panel diffusers easy to maintain?
- EDI’s curvilinear panel diffusers allow fast membrane replacement in the field, typically within minutes—unlike flat panels.
What’s the benefit of fine vs. coarse bubble?
- Fine bubble diffusers deliver higher oxygen transfer rates and energy efficiency; coarse bubble units offer better mixing and clogging resistance.
Do you provide aftermarket EDI membrane replacements?
- Yes—EDA membranes and diffuser components are stocked or can be field-ordered through our SiteWorks™ parts support.
Can EDI support industrial wastewater with aggressive chemicals?
- Absolutely. EDI membranes and diffuser configurations are designed for chemical resistance and high-temperature tolerance. Alloy piping options and specialized membranes are available.
