Membrane SWC 31540R - code: ACSWC31540R - HP Watermakers

The SWC 31540R membrane (replacement code ACSWC31540R) is an element for systems of reverse osmosis intended for the treatment of sea water, used in desalination plants HP Watermakers. In a desalination system, the membrane is the central component of the process: it operates inside the high-pressure vessel and allows the separation between treated water (permeate) and saline concentrate.

Product identification

• Plant brand: HP Watermakers
• Spare part code: ACSWC31540R
• Description: SWC 31540R membrane
• Type: reverse osmosis (RO) membrane for seawater (SWC = Sea Water Composite)
• Application: HP Watermakers desalination systems

Features and details (confirmed data)

Below are the identification and dimensional data available for the membrane ACSWC31540R. This information is useful to verify compatibility with the vessel and the configuration of your desalination system.

• HP Watermakers code: ACSWC31540R
• Membrane type: reverse osmosis for seawater (SWRO)
• Designation: 31540R
• Nominal diameter: 3″ (≈ 76 mm)
• Nominal length: 40″ (≈ 1,016 mm)
• Configuration: spiral wound element (Spiral Wound)

The code 31540R identifies a membrane in the format 3″ × 40″, commonly used on desalters that adopt elements of this diameter and length for seawater applications.

Component function in the desalter

Inside a reverse osmosis plant, the membrane plays an essential operational role in the separation process. In particular, it helps to:

• separate dissolved salts present in seawater;
• allow the production of fresh water (permeate);
• retain most of the salts and other dissolved contaminants;
• operate inside the high-pressure vessel of the desalter.

Applications

The replacement ACSWC31540R is intended for HP Watermakers desalination units designed to use membranes 3″ × 40″ for seawater. It is therefore suitable when the plant uses this format and this type (SWRO) as the main separation element.

When it makes sense to replace the membrane

In maintenance, membrane replacement is normally considered when changes in plant behavior are observed or when scheduled interventions are performed on the osmosis circuit. In any case, the choice of the correct replacement always starts from identification: code, size and type must be consistent with what is specified by the plant manufacturer.

Advantages (from a spare parts perspective)

Selecting a membrane with correct identification and format consistent with the vessel helps keep the plant in an orderly and manageable configuration over time. In particular, this replacement offers practical advantages related to:

• Component recognizability: the code ACSWC31540R facilitates alignment between order, spare parts warehouse, and plant technical documentation.
• Dimensional consistency: the format 3″ × 40″ is a clear reference to verify suitability with respect to the vessel.
• Defined usage type: SWRO membrane for sea water, suitable for plants operating in this context.
• Construction configuration: element Spiral Wound, , typical of reverse osmosis applications.

Usage and operational notes

The membrane is a sensitive component and must be handled carefully during inspection, replacement, and commissioning of the system. Below are some general notes (not a substitute for HP Watermakers instructions):

Checks before ordering

• Check the spare part code: make sure it is ACSWC31540R.
• Verify format and type: the membrane is 3″ × 40″ for sea water (SWRO).
• Compare with the installed membrane: if possible, check the designation 31540R reported in documentation or on the existing element.

General guidelines for replacement

• Operate the system under safe conditions and according to the manufacturer's procedures.
• Handle the membrane element carefully during insertion/removal from the vessel, avoiding shocks or contamination.
• At the end of the intervention, follow the system procedures for restoration and functional checks.

Important note

This membrane is intended for systems HP Watermakers that use elements 3″ × 40″ for seawater. If your system uses a different format or type, it is advisable to verify compatibility through code and technical documentation before purchase.
