1812 Test Elements

Summary

Product identification

These TurboClean® 1812 Test Elements feature a patented sanitary hard-shell design, which provides about 60% less bypass flow compared to other sanitary elements. This design leads to energy savings, higher flux rates due to more feed flowing across the membrane surface, and more effective membrane cleaning from higher cross-flow velocity. The elements are stronger than net-wrapped sanitary elements, can withstand higher pressure drops, and offer easy loading/unloading due to tight OD tolerance and optimal circularity.

Important Information

• Start-up: MANN+HUMMEL Water & Fluid Solutions recommends flushing elements for 30 minutes at low pressure and discarding permeate during the flush prior to operation.
• Cleaning: TurboClean® membrane elements must be cleaned periodically.
• Storage: TurboClean® membrane elements must be stored appropriately.

Customizable specialty elements are available for challenging water and process applications, including low-fouling RO, submerged UF, continuous high temperature, ultra-high pressure, and unique sanitary designs.
