What makes a great water treatment tank lining?

The lining of a water treatment tank is an essential component of a water treatment system. A water treatment lining is a protective coating that is applied to the inside and outside of the tank. The lining protects the tank against corrosion, contamination, and leakage. Whatever type of tank you have, a water treatment tank lining can add durability and longevity. Water tanks are made of a variety of materials, including steel. Many people have relied on steel to transport and store water for over 150 years. Filter beds, clarifiers, and troughs all have water treatment tank linings. Consider the following options for water treatment tank lining.

Stainless Steel

This is a typical water treatment tank lining. Stainless steel can be rough or polished, with rough being the most common.

Epoxy

A chemical-resistant material is used to create an epoxy lining. High temperatures and aggressive materials can be tolerated by epoxy lining. Epoxy is a strong and long-lasting lining that is resistant to moisture. It does not contain any solvents that could leach into the tank’s water. Epoxy is a versatile material with numerous applications.

Cementitious

Lining a cement tank with a cementitious liner is a common practice. It is, however, also used as a lining for underground tanks. Cementitious linings are ideal for containing chemicals in tanks. It can also waterproof underground areas. Because it is vapor permeable, a cementitious water treatment tank liner is ideal for underground use.

Polyurethane

Polyurethane linings are versatile and are commonly used in concrete structures. A polyurethane lining must be expressly intended for use as a tank lining. This lining contains no solvents, making it safe and simple to apply.

Polyurea

When it comes to lining water tanks, polyurea has only been around since the 1990s. This gel-like lining can be sprayed onto a tank. Polyurea also allows for quick and easy application. It is also a flexible and strong liner. It is abrasion resistant and solvent-free. This lining can be used to line steel and concrete tanks, as well as as a protective layer for chemicals.

Before deciding on which water treatment tank lining option is best for your tank, you must first understand how and where you intend to use it. This enables you to make the best choice.

7 Common Types of Water Tank Linings

Do you have a leaking tank or want to keep chemicals safe? Is your tank rusted and in need of repair? You can patch your tank, but this may not provide a long-term solution. Tank liners for water systems, on the other hand, could be the solution to your problem.

What are water tank liners?

A tank liner is a material that is used to form a strong and thick film that prevents chemical contamination, corrosion, and leakage. These liners are made of specialized fabrics made of various heavy-duty materials.

While their purpose is straightforward, the sheer number of available water tank liners can be bewildering at first. Here’s a breakdown of the most common types of tank liners for water systems on the market, as well as some of their advantages as tank liners.

Epoxy Linings

Epoxy tank coatings are made of epoxy material, which can be chemically resistant. They are strong, aggressive linings that can work in high-temperature environments. Because epoxy is moisture-resistant and solvent-free, it is an obvious choice for water tanks.

Polyurethane Linings

In terms of flexibility, polyurethane tank linings fall somewhere in the middle, though they are certainly more flexible than other options. However, they are ideal for concrete structures.

Vinyl Ester Tank Liners

Vinyl ester liners are made of vinyl and have some of the highest chemical infiltration and contamination resistance. Because of its high resistance to temperature and chemical damage, this material is widely used in most chemical industries.

Polyurea Tank Liners

In the tank lining industry, polyurea material is uncommon. Using specialized spraying equipment, this newer commercialized lining material is applied in a gel-like form. As a tank liner, polyurea offers exceptional flexibility and strength. It also has up to 900% elongation properties. Polyurethane comes in a variety of forms, each designed for a specific application. Polyurea tank linings are also resistant to abrasion and free of solvents.

Cementitious Liners

Cementitious linings are classified into two types: epoxy and polymer-modified cementitious linings. These materials are commonly used in the lining of concrete tanks used in water treatment and chemical storage. These linings are ideal for waterproofing retaining or collection structures underwater.

Zinc Tank Liners

A zinc tank liner is made of zinc silicate and is anti-corrosive. Its additives and binders have the potential to act as an effective waterproofing material. This material contains a high percentage of zinc dust. These liners provide zinc-to-zinc contact with cathode-like protective layers similar to those found in galvanizing. Because these linings are non-porous, cleaning them can be difficult. However. They can still contain chemicals safely. Because it fills the capillaries and pores, the zinc coating is effective. These coatings are also resistant to solvents and can be used to line solvent tanks. However, they are not resistant to bases or strong acids.

Stainless Steel Liners

Stainless steel linings are made from either polished or unpolished stainless steel. Rough-surfaced steel linings are the most common. Tanks with stainless steel linings should be cleaned on a regular basis to an ideal Water White Standard.

By purchasing the proper tank lining material, you can safely contain chemicals and prevent tank leaks from all types of tanks. There are numerous tank lining materials, and their effectiveness in serving as tank liners to prevent leaks and chemical contamination varies. Your liner selection should be based on a variety of factors, including its ability to serve as a perfect water-tight sealant.
