Can Drinking Water be Stored in Plastic Water Tanks?

Different storage products are used for various purposes in different fields today. When we look at the general usage of storage tanks, polyethylene water tanks come to the forefront. The purposes of storage products are quite diverse. They can be produced in various designs and sizes. In general, the purposes of usage include the protection of contents, regardless of whether they are organic or chemical, from seasonal and environmental conditions, facilitating the transportation of contents from one place to another if desired, and allowing the discharge of contents by using the drain valve on the tank when needed.

Storage products are produced using three different materials: polyethylene, polyester, and stainless steel. The most famous of these materials is polyethylene. Polyethylene is commonly known as plastic, but there are many misconceptions about polyethylene. One of the misconceptions is related to the belief that polyethylene is harmful to health. However, polyethylene is considered food-safe, and therefore, food or organic contents can be stored in these storage products without posing any harm to health. In fact, many products that encounter food are manufactured using polyethylene due to its food safety suitability.
 
The food-grade suitability of tanks produced using polyethylene has made water the most stored content in these tanks. Although there are ongoing debates about the drinkability of the stored water, it is important to note that the drinkability of the water depends entirely on the water itself, and the tank in which it is stored does not have any impact on its drinkability.

The main function of the tank is to protect the water against environmental conditions. If the water stored in the tank is potable, it can be consumed directly. However, if the water is not suitable for drinking, connecting a purification system to the drain valve of the tank can make it potable.

What are Plastic Water Tanks Used for?

Storage tanks are generally used for various purposes, which is why they come in different designs and sizes. There are even specific storage tanks used for pickling brine. In addition to pickling brine, silo tanks are used for grain storage. All these tanks are made from polyethylene. Moreover, due to their lightweight nature and design, these tanks are also used for the transportation of contents. We have compiled the information about which contents are stored in plastic storage tanks and for what purposes, as it is a frequently asked question.

1. Storage of Organic Contents

Polyethylene tanks are commonly used for storing organic contents. They are particularly popular for pickling brine storage. The most common content stored in these tanks is water. While we often associate storage tanks with liquid contents, they can also be used to store solid contents such as grains. Although organic contents typically refer to the food and beverages we consume, in industrial usage, they are used for storing organic products and semi-finished goods. From this perspective, storage tanks contribute to expediting production processes.

2. Storage of Chemical Contents

When it comes to chemical storage, there are numerous types of chemicals that come to mind. The working temperature range of polyethylene tanks is up to +50 degrees Celsius. However, when it comes to effective storage in the chemical industry, polyester water tanks are preferred. Polyester storage products are manufactured with the addition of isophthalic and epoxy-based vinyl ester resins to the production recipe, providing more effective storage for corrosive and flammable chemical contents. Harmful chemicals such as acids may come to mind when referring to chemical contents. However, it is not appropriate to store every chemical in any type of tank. Plastic storage tanks are more suitable for storing products such as detergents, glucose, diesel, and fuel. In this regard, underground tanks made from polyethylene material can also be preferred.

3. Storage of Solid Contents

People who have not used storage tanks before may mistakenly think that only liquid contents are stored in them but many solid contents can be stored in these tanks. The primary purpose of tanks is to protect and transport the stored contents. Solid contents cannot be discharged through the drain valve since they are in solid form. However, due to the wide diameter of the tank's opening, the stored contents can be easily discharged through the top opening. In addition, storage tanks made from polyethylene offer benefits in various areas for users.
