Evaluation of FRP Membrane housing – Features of FRP Membrane Pressure Vessels
During1990’s stainless steel and PVC membrane housings are used, but now FRP membrane housings are used. So in this article, we will discuss about the evaluation process, industrial places for the usage of FRP membrane housing and also the feature of FRP membrane housing.
FRP membrane Housing is introduced for chemical resistance, corrosion-free for the water purifying process. If anyone is facing issues such as corrosion, less chemical resistance power, less mechanical strength, and very high maintenance, they can now choose FRP membrane housing to resolve the problem.
Different industrial places for the usage of FRP membrane housing:
The following are the different industrial places for the usage of FRP membrane housing:
Water Treatment,
Reverse Osmosis,
Desalination plants,
Effuent Treatment Plants (ETP)
Sewage Treatment Plant (STP)
Food & Beverage Industry
Cooling Towers,
Power Plants,
Hospitals,
Railway stations,

Features of FRP Membrane Pressure Vessels:
The following are the features of FRP Membrane Pressure Vessels:
- All these are approved designs by only USDA for clean filtration of water.
- The Design parameters of FRP Membrane Housings are as per ASME standards.
- Available in different sizes of diameters and lengths
- You can safely consume clean and fresh water.
- It can be available in both high and low pressures of PSI units
- Low operational cost.
Evaluation of FRP Membrane housing:
During the 1990s, in place of FRP membrane, everyone used stainless steel, mild steel. After that, they observed corrosion, rust, and less resistance power if the water contains chemicals during filtration.
Now FRP membrane Housings are used to replace stainless steel, mild steel as they are corrosion-free had the best mechanism strength and chemical resistance. It also contains operating pressure from 300to 1500 PSI.
Different types of FRP membrane housing models:
There are two types of FRP membrane housing models. They are:
- End port
- Side port
End port:
The end port FRP membrane housing model is used for a plant with less than five membranes. So if we send feed water in one direction, wastage, purified water will come from the end side.
Side port:
To make an easy pipe, you need to prefer the side port model as the end port model is complex for large membranes. The side-port membrane housing model is used for plants with more than five membranes. If we send water in one direction, wastage, purified water will come from opposite directions.
How to calculate a number of elements in FRP membrane:
Follow the below procedure to calculate a number of elements in FRP membrane housing:
One element length= 40 inches.
Suppose if we consider 8 inches with five membranes:
The formula for calculating 8 inches with five membranes = 80 after (length (total membranes)).
(40(5)) = 200,
Then we need to place this 200 after 80.
= 80200
Therefore it 80200 model.
Suppose if you observe like 40240 model, then you think like this:
40 after (length (total membranes)
40 after (240)
40 after (40 inches (6 membranes)
Therefore it is 4 inches membrane housing with 6 membranes.

Characteristics and requirements of FRP membrane housing
Characteristics of FRP membrane housing made it special, and even small scale to large scale industries prefer FRP membrane housing for liquid treatment only because of its characteristics and performance.
In this article, We will explain about the characteristics, performance and requirements of FRP membrane housing.
Characteristics of FRP membrane housings:
The following are the characteristics of FRP membrane housings:
Excellent and reliable internal quality:
The FRP membrane housing is manufactured by a controlled CNC Filament winding unit with the best performance processing equipment. The primary materials are epoxy resin and fibreglass. This unique process is used to prepare the FRP membrane housing for temperature, pressure, and corrosion resistance. Its advantages are compared to any ordinary steel, plastic, and other materials that can’t match.
Good insulation performance:
The thermal conductivity of every FRP membrane housing is usually 0.15 – 1.36 W (m.k), only about 1/200 at room temperature, these thermal insulation properties are unmatched by all metal materials. This property greatly benefits the reverse osmosis membrane in the membrane housing and affects the membrane’s external temperature.
Best corrosion resistance:
The combination of both glass fiber and epoxy resin primarily acts as a natural anti-corrosion product. The inner surface is also very smooth, and the coating has the best stability to solvents like acid, alkali, salt, and oil with low concentrations. The seawater, microorganisms, etc. Which are entering the FRP Membrane housing are very effectively smothered so that there is no corrosion for Life term usage.
Structural design:
The design of the barrel, head, and groove of the FRP membrane housing is separated, and the calculation details are constantly optimized to make sure the structure’s safety. The concentrated water side opening is constantly optimized to meet all the necessary safety pressure for opening, especially the head’s four side ports, and improves variability during installation.
Component reliability:
The endplate is an important accessory of FRP membrane housings and has the best strength, best pressure resistance power, and high-pressure impact resistance. The seal is professionally designed as a “V+X” ring with an O-shaped endplate seal to ensure that it never leaks under any low or high-Pressure ranges. The side opening seal design combined with L-shaped drum round pads ensure the best sealing effect of the side opening mouth under that angular offset. The side opening is secured with a lifting-up affixing to make it more flexible.
Temperature maintenance:
The FRP membrane housing can mainly be used continuously for filter purposes for a long time, but to make sure long-term and best use of the FRP membrane housing strictly comply only with the temperature in between (-7c to 49c) that the product can withstand. Therefore, it is not safe to exceed this (-7c to 49c) temperature range and work under these conditions. Also, read the instructions pressure range for your FRP Membrane Housing.
Performance of premium FRP membrane housing:
The following are some of the performances of premium FRP membrane housing:
The internal structure performance is perfect, safe, trusted, and designed with good quality materials.
The matching components provide excellent sealing pressure performance.
Stoving varnish for external surface treatment always makes FRP membrane housing as best as new in hot and humid environments.
The universal property of pressure vessels is matched with multiple standard membrane elements, E.g., Filmtec, Koch, Hydranautics, Toray, Vontron, Kora, Osmonics, CSM, LG and BDX, etc.
Requirements for the usage of FRP membrane housing:
The following are the requirements for the usage of
FRP membrane housing:
- Comply with the best-rated design pressure index, ensure to use only allowable value; overpressure operations are strictly banned.
- The average working temperature of FRP membrane housing is usually between -7°C to 49°C. It is strictly banned to work beyond those temperature ranges.
- The FRP membrane pressure vessels can withstand at any pH range.
- The backpressure need not exceed up to 125PSI.
- Conventional fluid media is clear water, sewage, seawater; if used for special fluids, don’t hesitate to contact us (ALFA AEROSOL) in advance to avoid accidents.
- When the system is working, or there is pressure in the membrane pressure vessels, it is strictly banned to knock, disassemble or move that membrane shell and control the influence of surrounding vibration sources.
