OV-L-4040
Low-pressure brackish water RO99.7% stabilized rejection under the stated 2,000 ppm NaCl test conditions.
4040 RO Membrane Manufacturer
4040 RO membrane elements selected by water chemistry.
OVAY 4040 elements cover low-pressure brackish water, fouling-resistant industrial water and seawater desalination duties. Selection should start with feed salinity, fouling risk, required rejection, pressure window and system recovery rather than format alone.
4040Industrial RO format selected by feed-water duty.
Available Configurations
Choose the series before confirming the model.
Published flow and rejection data must always be read with the stated test conditions. The selected series page and datasheet provide the technical reference for project evaluation.
OV-FR-4040
Fouling-resistant industrial ROHydrophilic surface treatment and 34 mil feed spacer for challenging feed water.
OV-SW-4040-LE / HR
Seawater and high-salinity ROLow-energy and high-rejection options for high-salinity feed water.

Datasheets state the selected model's test conditions and operating limits. Final product selection should be confirmed against the real feed-water analysis and system design.
Industrial Buyer Brief
Match the membrane to the duty, not only the dimensions.
A 4040 inquiry may involve a compact industrial skid, a replacement element or a pilot system. The information below lets engineering and purchasing teams evaluate the same requirement.
Identify the feed
Municipal water, well water, process water, reuse water or seawater; include TDS, temperature and available analysis.
Define the target
Required permeate flow and quality, system recovery, operating pressure and daily operating profile.
State the configuration
Element size, current model, vessel arrangement, quantity and whether this is a new design or replacement.
Confirm deliverables
Datasheet, sample evaluation, labeling, packaging, batch records and other project documentation as required.
Selection Questions
What should be confirmed before quotation?
The same element format can contain membranes intended for very different salinity, fouling and pressure conditions. The final model should be confirmed from project data and its series datasheet.
Can an OV-L, OV-FR or OV-SW element be substituted only by size?
No. They serve different feed-water duties and operate under different test conditions and pressure windows.
Can OVAY review a current competitor or installed model?
Yes. Send the full model name, system duty and feed-water data so the proposed alternative can be evaluated on a specification basis.
Are OEM labels and technical documents available?
Private-label scope and project documents can be discussed after the technical model and destination market are confirmed.
