When it comes to highly chemical or reactive industrial processes, these call for more resilient scrubbing systems than usual that hold up better under intense corrosion. Known for their remarkable resistance in the face of all kinds of rough impacts, FRP scrubbers are proven to last significantly longer, significantly saving on maintenance and replacement costs. Today we are going to be covering what makes them so special and what they can do for industrial premises.
Definition and Applications
What is an FRP scrubber? Essentially, this comprises an air pollution control device. It funnels in and absorbs contaminants that are bad for people’s health and cause harm to the factory in which these chemical processes are taking place. The way they are treated is a special liquid that matches the environment, a specially concocted solution for the gases, fumes, and particulates in the environment. Its material, fiberglass, is known for being highly resistant to corrosion, chemical attacks, high temperatures, and other harsh conditions.
Here are some of the common industries where the FRP scrubber system works wonders
Here are some of the common industries where the FRP scrubber system works wonders
- Chemical industry: corrosive gases are often generated such as HCl, SO2, and NH3 out of the exhaust;
- Power generation: high levels of emissions are produced from combustion, including SO2 and acids;
- Pharmaceuticals & biotechnology: VOCs and airborne pollutants floating from production processes;
- Food & beverage: ridding environments of odors, vapors, and debris resulting from things like fermentation or frying;
- Metal & surface treatment: fumes, acid mists, and metal byproducts get set adrift following operations like electroplating;
- Wastewater treatment: Odors and harmful gases like H2S in treatment facilities.

Advantages of Using FRP Materials
Let’s break down the specific properties that render FRP scrubbers unique.
LIGHTWEIGHT
These scrubber FRP machines are lighter than metals like steel by a long shot. So when you’re transporting them to different places, having to install them, and performing maintenance operations, they’re convenient and are sold at low PP FRP scrubber quotes. There’s also less of a structural load on the edifices and supporting frameworks, allowing a large degree of design flexibility.
DURABLE & LOW-COST
No matter what extreme temperatures the PP FRP scrubber system is subject to and how much moisture it’s exposed to, it stands strong. The service life is especially impressive compared to its counterparts. If parts do need to be repaired or replaced, FRP scrubber quotes are quite low.
CORROSION-RESISTANT
They’re chemically resistant due to their thermosetting resin matrix consisting of vinyl ester or epoxy, featuring cross-linked inert polymer chains that resist chemical attack. The glass fibers provide strength and rigidity, preventing cracks and deformation. This bodes well under the influence of acids, alkali, and other such substances.
CUSTOMIZABLE & FLEXIBLE
Materials can be molded into complex shapes and sizes, allowing for tailored FRP scrubber designs that optimize performance and fit within the facility’s dimensions.

Horizontal BOREAS
ENVIRONMENTALLY FRIENDLY
The material is highly sustainable and easy to recycle, thus rendering it a responsible choice for industries looking to make less of an environmental footprint. The fact that impurities are being neutralized and very little of them is exiting into the environment and atmosphere also furthers sustainability goals.
FRP wet scrubbers also improve airflow and reduce resistance, thus enhancing energy efficiency and reducing consumption, also resulting in a cheaper utility bill for the enterprise.
EASY MAINTENANCE
The materials are easier to clean than metals, due to their smooth surface, which is not amenable to the buildup of contaminants. Thus cleanup is simpler and there is less downtime.

Main Types of Systems
Here are the main types of FRP scrubbers encountered.
Packed bed scrubbers
These filters entail a packed column through which gas courses. Upon entering the wet scrubber, it collides with scrubbing liquid until being led down into a disposal tank. The water is then reentered into circulation to absorb the next gases.

Venturi
An FRP venturi scrubber features a narrowing neck design that forces gases and cleaning liquids together at high velocity, thereby increasing the absorption rate. These are effective for fine particles though they use a lot of energy.

Dry scrubbers
These use dry media like activated carbon to adsorb or neutralize pollutants. Commonly used in power plants and waste treatment, they come in handy for acidic environments.

Tray Tower (Plate Column)
Foam devices are most often equipped with so-called overflow trays (slotted or perforated), which are irrigated with liquid. The foam formed on these trays captures dust particles, which are removed from the device as sludge.

Key Design Parameters
Here are some of the main factors to keep in mind. All of these will need to be adjusted based on the recommendations of the FRP scrubber manufacturers to ensure top-notch performance and efficiency.
This table provides a clear and organized way to understand the key parameters to consider when designing an FRP wet scrubber.
Primary Technical Specifications
Throughout the life and operation of the machine, users have to keep a watch on performance to ensure that it’s operating at the maximum level while staying economical in consumption. Here are the factors to account for in an FRP scrubber specification.
- Pressure drop — measured as inlet-outlet pressure difference (in WC or Pa); keeping this at the ideal value means less energy consumed.
- Fan & motor — defines airflow (cfm/m³/h) and motor power (HP/kW) required to move gas through the system.
- Gas flow rate — determines the PP FRP scrubber’s size and capacity, measured in CFM or m³/h.
- Pollutant concentration — the type and the volume of the pollutants present will affect which scrubbing liquid is chosen, the configuration, and at which efficiency level contaminants will need to be removed.
- Scrubbing liquid flow rate and pH — a balance must be struck between utility costs and the amount of pollutant captured.
- Gas-to-liquid ratio (G/L) — this impacts mass transfer efficiency; a lower one means higher-level removal but greater cost and vice versa.
- Removal efficiency percentage of pollutants removed, requiring greater time in contact, liquid chemistry, and superior media design.
- Pressure & temperature — this affects how well contaminants dissolve and the system performs.
