STAR · 8″×40″ · Low Pressure (LP)
STAR LP8040 RO Membrane
The STAR LP8040 RO Membrane is an 8″×40″ low-pressure (LP) series brackish water membrane for industrial reverse osmosis systems; its thin-film composite structure lets it work at a lower feed pressure while delivering high salt rejection, cutting pump energy and running costs.

- Brackish Water RO
01Problem & Solution
Pressure Decides the Bill
Problem
High Pressure, High Energy
The largest running cost in a reverse osmosis system is the energy of the high-pressure pump that drives water through the membrane. High pressure also puts a constant load on the pump, the pipework and the seals.
Solution
High Output at Low Pressure
As a low-pressure (LP) series element, the STAR LP8040 RO Membrane works at a lower feed pressure than a standard membrane. Energy consumption falls and so does the load on the equipment.
02Key Features
An Energy-Efficient Industrial Membrane
The STAR LP8040 RO Membrane brings output and energy saving together in industrial-scale treatment.
Low Pressure (LP) Series
Working at a lower feed pressure than standard membranes cuts pump energy.
High Salt Rejection
It separates dissolved salts, heavy metals and ionic contaminants from the water at a high rate.
Thin-Film Composite Construction
A polyamide thin-film composite layer in a spiral-wound body gives steady performance.
Standard 8″ Fit
It fits standard 8″×40″ pressure vessels and integrates easily into existing industrial systems.
It Extends Equipment Life
A lower working pressure eases the load on the pump, the pipework and the seals, reducing the risk of failure.
Many Uses
It is widely used in industrial process water, drinking water plants and pure water systems.
03Technical Specifications
Membrane Specifications
| Feature | Value | What it does |
|---|---|---|
| Model | STAR LP8040 | The manufacturer’s model code. Spares and service are matched by this code. |
| Size | 8" × 40" | The physical size. If a spare does not match this, it will not go into the housing. |
| Series | LP (Low Pressure) | The product family. Parts within the same series fit one another. |
| Type | Brackish Water RO | The product sub-class. When buying a spare it has to match the one you already have. |
| Construction | Thin-Film Composite | How the unit is put together. A compact cabinet takes little room; an open system makes servicing easier. |
| Winding | Spiral (FRP Body) |
04Applications
Where Is It Used?
The STAR LP8040 RO Membrane is used in industrial-scale reverse osmosis systems.
- Industrial Process Water
- Drinking Water Plants
- Pure Water Systems
- Boiler Feed Water
- Factories
- Well Water Systems
- Food & Beverage Plants
- Membrane Replacement
05How It Works
How Does the STAR LP8040 RO Membrane Work?
Pre-Treatment and Chlorine Removal
Raw water passes through the sand and carbon stages; sediment and chlorine are removed and the membrane protected.
Pressurised Feed
The pump pressurises the water, and because this is the LP series a lower pressure than usual is enough.
Salt Separation at the Membrane
The polyamide thin-film layer lets water through while holding back the great majority of dissolved salts and ions.
Permeate and Concentrate Outlets
The treated water goes to the process and the high-salinity concentrate is discharged through a separate line.
Cleaning and Replacement
When output falls the membrane is cleaned chemically, and at the end of its life it is replaced.
06Making the Right Choice
What Decides the Right Membrane
When choosing the STAR LP8040 RO Membrane, water type, capacity and system compatibility must be assessed correctly.
Water Type
This membrane is for brackish water; very high salinity such as seawater calls for the SW series.
Energy as a Priority
In plants where the electricity bill is critical, the low-pressure (LP) series is a clear advantage.
Capacity Requirement
The daily treated water requirement directly determines how many membrane elements are needed.
Housing and Pre-Treatment
A standard 8″ pressure vessel and pre-treatment that removes chlorine are essential to the membrane’s output.
07Maintenance and Use
Notes That Extend Its Life
- Free chlorine damages the membrane permanently; chlorine must be removed by a carbon filter ahead of it.
- In high hardness, softening or antiscalant dosing should be used to prevent scaling.
- Permeate conductivity and differential pressure should be monitored; deviations give the chance to act early.
- The membrane should be kept wet, a preservative solution used during long shutdowns, and replacement carried out by a technical service engineer.
08Frequently Asked Questions
Common Questions
What does the STAR LP8040 RO Membrane do?
It is an 8″×40″ brackish water membrane that removes dissolved salts, heavy metals and ionic contaminants from water in industrial reverse osmosis systems. Being a low-pressure element, it works on less energy.
What does “LP” mean?
LP stands for the Low Pressure series. Because these membranes can work at a lower feed pressure than standard ones, pump energy and the electricity bill fall, and so does the load on the equipment.
What does “8040” mean?
8040 is the standard industrial size of the element: 8 inches in diameter and 40 inches long. It fits standard 8″ pressure vessels made of stainless steel, PVC or FRP.
Can it be used on seawater?
No. The LP8040 is a brackish water membrane. Seawater involves far higher salinity and far higher pressure; those applications call for the seawater (SW) series.
Is it sensitive to chlorine?
Yes. Free chlorine and oxidising agents damage the membrane permanently. Chlorine must therefore be removed by an activated carbon filter ahead of it, and in high hardness precautions should also be taken against scaling.

Questions & Answers
Questions asked about this product
Questions on compatibility, capacity and installation are answered by our technical team. The answers stay public — so the next person with the same question can see them too.
No questions have been published for this product yet. You can be the first to ask.
Installation and commissioning
Installation is a service · plumbing is the customer’s responsibilityThe system is delivered ready to install; it only needs to be connected to the inlet and outlet lines. If valve setup is required, we provide free support over a video call. Installation and commissioning fall under our service work and are subject to a service fee. Plumbing labour and any pipes, valves and fittings are not included in the price; these items are the customer’s responsibility.
Warranty
2 years · manufacturerThe system is covered by a 2-year manufacturer warranty. During the warranty period, labour and parts are free for faults arising from manufacture or installation. Consumables such as filters, membranes and resin are outside warranty cover — they are replaced when their service life ends; they do not fail.
Withdrawal and returns
Distance sales agreementThe right of withdrawal and the return terms are set out in detail in the distance sales agreement. Systems that have been installed and commissioned, and made-to-order products, are outside its scope.
