RO Membrane Element SWC5-LD-4040

Hydranautics SWC5-LD-4040 membranes are available in a range of innovative formulations that are suitable for varying degrees of seawater salinity. They are an excellent choice for customers seeking to optimise salt rejection and permeate fluxes. Each offers the highest productivity and salt rejection rates in the industry, combined with optimised flow, low fouling and low energy consumption. These membranes are particularly useful when lower permeate TDS and lower feed pressures are needed. In addition, SWC5-LD-4040 membranes offer maximum energy efficiency at the lowest costs, making them a popular choice for use in large-scale desalination plants.
Hydranautics SWC5-LD-4040 Product Data Sheet

Specified Performance

Permeate Flow	1,750 gpd (6.62 m³/d)
Salt Rejection	99.7% (99.5% minimum)
Test Conditions	32000 ppm NaCl solution
	800 psig (5.5 MPa) Applied Pressure
	77 ℉ (25 ℃) Operating Temperature
