AWWA D103-97 standard Epoxy coated steel tanks as municipal wastewater tank

Municipal wastewater treatment is a crucial component in the development of modern cities. With the advancement of urbanization, population growth, and industrialization processes, the volume of wastewater discharge continues to rise, posing significant challenges to the environment and public health. Therefore, an effective municipal wastewater treatment system is paramount for maintaining urban environments and ensuring the well-being of the population.

Traditional sewage tanks primarily utilize metal materials, such as steel. However, these materials have evident limitations. Metal containers are susceptible to corrosion and rust, which restrict the lifespan of the tanks. Additionally, metal tanks are typically heavy, leading to high transportation and installation costs, and they may encounter stability and durability issues when subjected to external pressure and long-term use.

Epoxy resin is a synthetic material renowned for its outstanding performance. Its key characteristics include high corrosion resistance, superior strength and durability, and the feasibility of lightweight design. These attributes make epoxy resin an ideal material for replacing traditional metal tanks, particularly in the field of municipal wastewater treatment. Epoxy resin tanks offer numerous advantages over traditional metal tanks. They not only resist the corrosive effects of chemicals, extending the tank's lifespan, but also exhibit improved stability and durability when facing external pressure and prolonged usage. Furthermore, epoxy resin tanks, with their lightweight design, reduce the burden of transportation and installation, enhancing construction efficiency and providing a more feasible solution for the development of wastewater treatment systems.

With over 30 years of experience in tank research, production, and construction, Center Enamel, in collaboration with the world-leading paint and coating manufacturer AkzoNobel, has jointly developed the technology of fused epoxy coating. Epoxy coating is an advanced anti-corrosion coating known for its excellent corrosion resistance and adhesion. Additionally, the epoxy coating technology employs a special construction process - electrostatic spraying, which enhances the uniformity and adhesion of the coating, effectively extending the lifespan of the tank.

Tanks coated with epoxy resin using this technology are not only technologically advanced and cost-effective but also easy and quick to install. The quality meets requirements such as AWWA D103-09 and ISO 9227/ASTM B117. Upon its introduction, it has gained recognition from customers.
