Reverse osmosis FRP tanks are an important part of the reverse osmosis system and are used in the filtration process. It’s a composite material tank that holds filtered water from a reverse osmosis system. The size of the tank depends on the size of the system and the amount of water that needs to be filtered.

RO FRP tanks

If you are wondering if RO FRP tanks would be useful for your industrial process, use this guide for an overview of FRP tanks. It covers the basics of FRP tanks, how they are manufactured, some of their common uses, and their features and benefits.

What are FRP tanks?

FRP tank is made of composite material with glass fiber and its products (glass cloth, yarn, etc.) as reinforcement and synthetic resin as the matrix. Reverse osmosis FRP tanks are mainly used for filtration in the water treatment industry. This container can be used as a pretreatment stage before the reverse osmosis membrane, mainly to remove particles, turbidity, odor, etc. It can also be used as a softener.

FRP (fiberglass reinforced plastic) tanks offer a number of benefits over conventional industrial materials. The size of the FRP water tank can be customized according to your industrial needs. Depending on the flow rate, the most suitable model will be recommended to you. Brother Filtration FRP tanks are excellent for numerous applications, long-lasting, and economical.

Features of FRP tanks

The FRP filter tanks from Brother Filtration are among the most low-maintenance and energy-efficient filtration systems available. Our filters are made of fiberglass for exceptional efficiency and extended life under tough chemical conditions. Before leaving the factory, each canister is tested for uniformity and has a 100% factory pressure rating.


FRP tanks are manufactured by adding a smooth resin-rich layer to reduce friction to achieve high surface corrosion resistance of FRP tanks. The tank is also lined with FRP/PE for added corrosion resistance and is resistant to most chemicals used in industrial applications. Our FRP tanks ensure resistance to the corrosive substances present in wastewater and sewage systems.



FRP has a good anti-rust effect because it is made of continuous glass fiber filaments and high-strength epoxy resin. We manufacture FRP using superb resin technology to provide the best FRP design. At the same time, we have cutting-edge production technology, which can produce high-quality, ultra-durable water tanks.


The difference between FRP tanks and stainless steel tanks is mainly reflected in the fact that the weight of FRP is much lighter than that of stainless steel, which is about one-third of that of stainless steel. This means that FRP is easier to deliver and transport, which greatly saves time and economic costs. And it is very portable and easy to install and operate, requiring only the use of plumbing and electrical connections.

The flexibility of Custom Design

To fulfill your site-specific needs, we can provide products that are customized. Customers have the option to describe their needs, and the shape and size of the tank they want, and all of these factors are taken into account throughout the engineering and design phase thanks to variations within our design process. FRP tanks are more cost-effective because they are strong and require less maintenance.

Advantages of FRP tanks

Fiberglass tanks and vessels go beyond where metals cannot for reasons of chemical resistance, upkeep, or cost. They are corrosion-resistant, lightweight, and most importantly, maintenance-free. Fiberglass Reinforced Plastic (FRP) Tanks and Process Containers Provide the Following Benefits:

  • Exceptionally resilient to the majority of the modern chemicals used
  • Not going to rust, rot, peel, chip, crack
  • Greater weight-based strength than steel
  • Resistant to corrosive plant conditions and ultraviolet light
  • Offering great thermal insulation when they are insulated or heat traced.
  • Able to withstand stray and galvanic electrical currents

Brother Filtration supplies extremely easy-to-handle, user-friendly, and cost-effective FRP filters for a variety of applications all over the world. Our goal is to provide safer, cleaner, and healthier water by removing biologically harmful contaminants.

Applications of FRP tanks

As implied by its name, an FRP vessel for water treatment, it is capable of filtering both suspended particles and offensive odors. By lowering the content of calcium, magnesium, and other metal cations to soften hard water for the purpose. Any liquid or gas that won’t corrode FRP can be stored in them.

The water filter FRP tanks are actually gradually replacing metal tanks in several fields due to their significant advantages. FRP tanks are widely used in the treatment and storage of domestic, commercial, and industrial water, including the electroplating wastewater treatment industry, industrial boilers, chemical industry, light industry, textile, and many other fields.


Are Fiberglass Tanks More Effective Than Steel Tanks?

In terms of weight, steel water tanks are much heavier than Brother Filtration FRP tanks, about three times as heavy. That’s why FRP fiberglass tanks cost less. And because of their lighter weight, FRP tanks can be used faster and more efficiently. More importantly, because of its better corrosion resistance, its service life is longer and more durable.

It is precise because of the particularity of its manufacturing materials that it is more elastic and durable than other materials. FRP storage tanks can provide absolutely safe and sealed storage functions for stored items. For corrosive water, such as seawater, FRP can also be effectively treated.

Fiberglass Tanks


In many different industries, such as water treatment, thermal power plants and projects, dyes, medicines, and so forth, FRP pressure vessels are used. It is without a doubt a revolutionary invention that has made a variety of technical processes simpler. It is a crucial part of the industry and is mostly used.

Brother Filtration provides the most complete water treatment filtration products, and there are a variety of sizes of large-capacity series of FRP pressure tanks to choose from. We try to cover the different needs of various industries and provide our clients with a wide range of options.
