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

Aggressive cleaning protocol cleaned NALA but damaged the polyamide membrane

A New Generation of Reverse Osmosis Membranes, the smartest choice for water reuse

NALA Membranes' logo
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
