Harnessing the Power of Purified Tannin: A Natural Solution for Water Treatment

Tannins have been used in water treatment for a number of years, however Purified Tannins are quickly becoming the number 1 choice for businesses that rely on steam boilers and cooling towers. That’s because Purified Tannins offer many advantages over traditional Non Purified Tannins and is also a green, renewable water treatment option.

And while Purified Tannins are becoming increasingly popular, we are delighted to say we are the 1st supplier to provide SOLID FORM PURIFED TANNIN. This means the Purified Tannin can be dosed into your system automatically, providing you with improved performance of equipment while saving on significant costs like fuel and water usage and labour.

Purified Tannin is a simplified treatment program, often turning 3 products into just one; instead of purchasing 3 separate chemicals this all in one solid chemical does it all for you!

What is Purified Tannin? – A brief explanation..

Tannins are natural organic compounds commonly found in various plant sources, including barks, fruits, leaves, and seeds. Purified tannin refers to tannins that have undergone a process of extraction and purification to obtain a refined and concentrated form of the compound.

In water treatment applications, purified tannin is often employed as a coagulant and flocculant. Coagulation involves the addition of a coagulant to destabilize and clump together suspended particles, organic matter, and other impurities present in the water. Tannins act as coagulants by binding with these particles and causing them to form larger flocs.

Flocculation follows coagulation, where the formed flocs continue to grow in size and settle more easily. This process aids in the removal of impurities and suspended solids from the water. The combination of coagulation and flocculation helps to improve water clarity, reduce turbidity, and enhance the efficiency of subsequent filtration steps.

Purified tannin can offer several advantages in water treatment. It is a natural and environmentally friendly alternative to synthetic coagulants and flocculants. It is biodegradable and poses fewer health and environmental risks. Additionally, tannins can enhance the taste and odor of water, making it more appealing for consumption.

The specific application and effectiveness of purified tannin in water treatment can vary depending on the water source and its quality characteristics. Factors such as dosage, pH, and contact time need to be carefully considered and optimized for each treatment system. Consulting with water treatment professionals and conducting appropriate testing is crucial to ensure the proper and effective use of purified tannin in water treatment processes.

Benefits of Purified Tannin

Using purified tannin for steam boiler and cooling tower treatment offers several advantages, these advantages include a boost to boiler efficiency, a significant reduction in operational costs, as well as an ability to remove existing scale deposits and protect against corrosion. Here are some other key benefits:

Corrosion Inhibition: Purified tannin acts as a corrosion inhibitor, forming a protective layer on metal surfaces within the steam boiler. This layer helps prevent corrosion and extends the lifespan of the boiler system.

Scale and Deposit Control: Tannins have properties that help control scale and deposits in steam boilers. They can inhibit the formation of scale on heat transfer surfaces, reducing the risk of blockages and maintaining efficient heat transfer.

Oxygen Scavenging: Tannins possess oxygen scavenging properties, which means they can help remove dissolved oxygen from the feedwater. This is crucial because oxygen can cause corrosion in steam boiler systems. By removing oxygen, purified tannin helps protect the system from corrosion-related issues.

Natural and Environmentally Friendly: Purified tannin is derived from natural plant sources and is biodegradable. Unlike some synthetic boiler treatment chemicals, it is considered environmentally friendly and poses fewer health and safety risks.

Reduced Chemical Usage: By utilizing purified tannin, there may be a reduced reliance on harsher chemical treatments. This can lead to lower chemical costs and a decrease in the overall chemical footprint of the steam boiler system.

Improved Water & Steam Quality: The use of purified tannin can help maintain steam quality by preventing the buildup of impurities and contaminants. Cleaner steam reduces the risk of equipment fouling and improves overall system efficiency. It also helps maintain water quality in cooling tower systems. It reduces the presence of impurities, such as organic matter and suspended solids, which can contribute to fouling and decreased system efficiency. Cleaner water promotes better heat transfer and overall system performance.

Microbiological Control: Purified tannin has antimicrobial properties that help control the growth of bacteria, algae, and fungi in cooling tower systems. By inhibiting microbiological growth, it reduces the risk of biofilm formation, fouling, and potential health hazards associated with certain microorganisms.

It’s important to note that the effectiveness of purified tannin for steam boiler treatment can depend on various factors, such as water quality, system design, and operating conditions. Therefore, it is advisable to consult with water treatment professionals and conduct appropriate testing and analysis to ensure proper dosage and treatment for your specific steam boiler system.

In addition to directly improving and cleaning boiler and boiler applications, purified tannin technology is simple and convenient. Installation of purified tannin is quick, easy and does not require additional equipment or capital investment. It can be applied with a single feed point, making transition painless. Purified tannin is also easy to test and does not require titration. Operators can simply perform a color comparison test regularly to ensure proper application. Finally, purified tannins can be formulated as a one-drum treatment for easier storage and minimal handling.


Among the numerous benefits listed above, Purified Tannin is a green, safe, and environmentally-friendly product from Renewable Resources.

Purified Tannin is mostly composed of natural ingredients extracted from tree bark. It is a renewable technology that is friendly to the environment on top of being an effective treatment solution, and while some chemicals can be toxic and potentially dangerous, purified tannin is a natural and non-toxic treatment solution.

Testing of Purified Tannin has consistently shown a significant reduction of water usage, wastewater generation, and greenhouse gas emissions which is minimizing your overall Environmental Footprint. The blatant advantage of using tannin products is the reduction in toxicity compared to traditional boiler water treatment programs. Tannins are found naturally in water systems as plant biomass decomposes and leaches. And being extracted from plant material, tannin products offer a renewable source that can be harvested sustainably compared to mining for phosphorus, sodium dioxide, or sodium carbonate.


In conclusion, Purified Tannin is a powerful and natural solution for water treatment, offering numerous benefits in various applications such as steam boiler and cooling tower treatment. Its corrosion inhibition, scale and deposit control, oxygen scavenging, and microbiological control properties make it an effective and sustainable choice.

Purified Tannin is derived from natural plant sources, making it environmentally friendly and biodegradable. With reduced chemical usage, improved water and steam quality, and simplified treatment programs, purified tannin offers a comprehensive solution for water treatment needs.

Embracing purified tannin not only enhances performance and efficiency but also promotes sustainability by minimizing environmental footprint and toxicity. By harnessing the power of purified tannin, businesses can optimize their water treatment processes and contribute to a greener and more efficient future.
