International brand dossier
OLTREMARE
Oltremare is a MANN+HUMMEL RO membrane product line covering low-pressure compact and XL elements, brackish-water, seawater, and low-fouling elements.It is relevant where light industrial, domestic, brackish, marine, and challenging feed applications require compact spiral-wound membrane families with defined replacement sizes.
OLTREMARE's position in RO/NF membranes and related equipment is defined by product families such as RO, NF, UF-adjacent membrane elements, membrane contactors, pressure vessels, housings, and related separation products.
The portfolio is best understood inside brackish water, seawater desalination, ultrapure water, process separation, reuse, degassing, and membrane system packaging, where engineers compare the technology route, family boundaries, and duty fit before narrowing to individual models.Representative series on this page include AsHR-2540, AsHR-4040 and AsHR-8040.Engineers should compare element size, salt rejection, permeate flow, pressure rating, fouling resistance, connection type, and vessel fit.

How to choose OLTREMARE RO Membranes
This section answers two questions: which main product families OLTREMARE offers, and which parameters to compare before choosing a specific model.
Step 1: Choose a product family by application
The main families shown on this page are Select here your pré-selection. Start with the treatment objective, equipment format, and operating duty, then use the model index below to compare exact specifications.
Step 2: Confirm the model by key parameters
After choosing a product family, compare feed salinity, target salt rejection, permeate flow, operating pressure, fouling tendency, and element size and connection. Replacement projects should also verify installation or loading conditions, interfaces, and compatibility with the existing system; new projects should consider operating practice, maintenance, and spare-parts or consumables availability.
