Concrete tanks and other infrastructure used in waste water treatment systems are usually exposed to various types of chemicals. Over time, these chemicals can corrode the system's components and cause premature aging and malfunction. For example, the reinforcing steel used together with concrete is prone to chemical attack, and this can affect the structural integrity of the concrete tanks. Choosing the best protective coating for infrastructure in a waste water treatment system is critical to maintaining structural integrity and improving the efficiency of the plant. Here are three coating systems that you can choose to prevent deterioration of equipment in the system.

Polyurethane and polyurea coatings

The primary cause of corrosion, abrasion, and chemical attack on steel-reinforced concrete tanks and other infrastructure in a waste water treatment system is direct contact with chemicals. That is why you need to use coatings that protect the equipment from direct contact with the water. Polyurethane and polyurea coatings are waterproof products that create an elastic lining on the surface of your equipment. They are ideal for use on concrete structures within the system. The resultant barrier prevents water from seeping into the concrete and corroding the steel metal used therein. Polyurethane and polyurea coatings are low VOC, and they don't contain any odours. This makes them sustainable products for use.

Solid-Based Epoxy coatings

When choosing protective coatings for water treatment systems, you should consider the application process for the product. Coatings that don't perform well in wet conditions may not be ideal for use in a waste water treatment system. Epoxies, particularly the solid-based ones, make excellent options for infrastructure in treatment systems. Epoxies adhere correctly to wet surfaces, and they can cure in a moist environment. Additionally, they can be easily applied using a trowel or spraying equipment. Epoxy coatings are corrosion-resistant and will protect concrete and steel infrastructure even when exposed to the harshest waste water treatment chemicals.

Coal Tar Epoxies

If your treatment system does not use harsh chemicals, coal tar epoxies are an ideal choice. These coatings protect infrastructure against abrasion and mild chemicals. They are heavy duty coatings, and you can apply them at a high film thickness in just one coat. Just like the solid-based epoxies, these coatings cure well in wet conditions. They are relatively easy to apply, and they do not require additional equipment during the application process.

Choosing ideal coatings for the infrastructure in a waste water treatment system is a critical step in ensuring the efficiency of the system. Contact a professional if you have trouble selecting the best product for the task.
