Internal coating of activated carbon filter tanks with PROGUARD CN 200

One company located in Germany fabricates complex devices and tanks for filter technology and water treatment as well as large steel construction. Recently the company produced 6 huge filter tanks for gravel and activated carbon filtration. To provide durable value preservation for the customer, the inner area of the tanks were coated with Ceramic Polymer GmbH system PROGUARD CN 200.

For long-term corrosion protection of gravel filters and activated carbon filters, the internal coating has to provide outstanding physical properties. In this case, the main focus is on a supremely high abrasion resistance since gravel, sand and sharp-edged granular activated carbon (GAC) induce heavy abrasion through constant friction.

PROGUARD CN 200 offers beside excellent chemical and thermal resistances a high-grade abrasion protection. Thus, the coating is perfectly suitable for this scope of application.

The coating is applied by airless spraying process directly on the prepared substrate – generally, only one layer is enough for the corrosion protection.

In this project, a thickness of 500 μm was applied. Flanges and holes were treated with brush or roller. The fast curing time of this product also allowed a rapid return to service for the customer.
