CPA5-LD – Low Differential Pressure (LDTM) Design
99.7% Salt Rejection
Provides extremely pure permeate water.
Enhanced removal of silica, nitrates, and other difficult ions.
Membrane Area: 400 ft²
Same physical size as CPA3 but upgraded with Low ΔP design technology.
Improved hydraulic profile that reduces internal pressure drop.
Patented 34-mil Feed Spacer
Enables deeper and more effective membrane cleaning.
Higher tolerance to suspended solids and particulate fouling.
Reduced Cleaning Frequency
LD design + improved spacer reduces fouling rate.
Lowers OPEX due to fewer clean-in-place (CIP) cycles.
Delivers consistent long-term performance and extended membrane life.
CPA5-MAX – High-Area Variant for Polishing & Low-Fouling Applications
Membrane Area: 440 ft²
10% more area than CPA5-LD.
Ideal for polishing RO or feed water with relatively low fouling potential.
Reduces CAPEX by lowering the number of pressure vessels required.
Optimizes plant footprint and overall cost per m³.
Availability

Benefits for Plant Designers & Operators
Higher ion rejection, including challenging species like silica & nitrates.
Lower differential pressure and reduced fouling rate.
Longer intervals between cleanings → Lower operating cost.
Flexible sizing options for small, medium, and large systems.
Reliable performance even under varying feed quality conditions.
