Industrial process water
-
Brackish water treatment
The CPA family includes CPA2, CPA3, CPA5, CPA6 and CPA7 configurations, offering different combinations of rejection, productivity and operating characteristics.
LFC® – Low Fouling Composite
LFC® membranes are designed for applications where feedwater has a higher potential for organic and colloidal fouling.
The technology combines a hydrophilic membrane surface with low-fouling characteristics to improve membrane performance under challenging feedwater conditions.
LFC membranes are suitable for:
-
Municipal wastewater
-
Industrial wastewater
-
Surface water
-
Reclaimed water
-
Difficult feedwater applications
Hydranautics' LFC product family includes configurations incorporating LD Technology® for demanding feedwater conditions.
LD Technology®
Hydranautics' LD Technology® is incorporated into selected membrane products to provide improved resistance to colloidal fouling and lower differential pressure characteristics.
LD Technology® membranes are available across selected ESPA, SWC, CPA and LFC product families and are particularly useful for applications involving reclaimed water, surface water, difficult well water and other challenging feedwater conditions.
