WET designed, manufactured, and implemented the industry' very first large scale nanofiltration water filter system. Water Equipment Technologies did this using modern day spiral wound membrane technology in 1988 and that nano water filter system is still in use today. Since then WET has and continues to supply a number of nanofiltration systems for commercial, industrial and municipal applications worldwide. The nanofiltration water filter system has ranged in sizes up to 6 MGD. Each nanofiltration system is custom designed and manufactured to meet our clients specific needs. We can build the system to exact specifications, or Water Equipment Technologies will assist in the design and development of a custom nanofiltration system in our state-of-the-art facility.
