The NALA Difference

NALA Patented Layer
Standard Microporous Layer
Standard Non-woven Layer
-
Standard TFC components
-
Patented sulfonated polysulfone seperation layer
NALA Membrane's smoother surface = less fouling

NALA Membranes stable to high levels of chlorine bleach
NALA TFC

Commercial PA-TFC

Aggressive cleaning protocol cleaned NALA but damaged the polyamide membrane
A New Generation of Reverse Osmosis Membranes, the smartest choice for water reuse

Conventional
Polyamide
NALA's Competitive
Advantage

Stable to Chlorine
Yes
No
Chlorine eliminates biofouling to reduce energy, downtime, and cleaning that damaged membrane

Surface Features
Smooth
Rough
A rough surface traps contaminants that results in fouling/clogging
pH Range with High
Salt Rejection
2 - 12
5 - 10
Wider pH range with high rejections adds capability


Cleaning Cycle
Short
Long
Less Downtime: More durable membranes can be cleaned faster without risk of damaging them.

Operating Costs
76%
100%
Elimination of biofouling reduces operating costs impactfully
