In recent years, the use of stainless steel in water and wastewater treatment plants (WWTP) has grown significantly as type 304 and 316 grades are increasingly utilized as standard materials of construction due to superior performance and cost-saving factors.
A WWTP is a complex, sophisticated system with a high-level of standards for the entire plant, including technical installations. The materials needed to construct a WWTP must be able to withstand the wide range of corrosive conditions.
For a clean, environmentally safe and cost-effective plant, there is no better material than stainless steel. Stainless steel will improve efficiency, reduce maintenance, and in many cases, provide the most cost-effective solution.
Benefits to this industry include:
- Corrosion resistance to a wide range of waters, chemicals, such as Hydrogen Sulphide (H2S)
- A protective layer forms naturally on all stainless steels because of the inclusion of chromium. Even if damaged and oxygen is present, the invisible passive layer self-heals and protects the steel from corrosion, ensuring a long life
- Stainless steel is not harmful to people during its production or use, recycling and ultimate disposal
- Good strength and ductility
- Ease of fabrication
- Lightweight and easy to transport
- Availability in a wide range of product forms
- Fully recyclable
