The ASRA system is specifically designed to effectively remove high to very high concentrations of suspended solids from mixed and single acid processes. These processes include hot rolled and annealed stainless and titanium flat product pickling, de-glassing, and pickling of stainless extruded products.
Thanks to its efficient filtration technology, the ASRA eliminates the need for cleaning solids accumulation from the process bath, enabling almost indefinite operation. This makes it a highly efficient alternative to sedimentation and other traditional filtration methods that are often inefficient in high-solids applications.
The ASRA operates with a series of woven thermoplastic fabric elements, a specially designed fiber-reinforced housing that is resistant to hydrofluoric acid, and PVDF piping, allowing it to withstand high temperatures commonly found in Sulphuric acid pickling. Additionally, the compact modular design and low waste generation of the ASRA, combined with its ability to produce a low-moisture solid filter cake without moving plates, makes it a superior option compared to filter press and other typical filtration technologies employed in high-solids applications.
Implementing the ASRA can provide numerous benefits, including: improved productivity by eliminating bottlenecks, energy and resource savings, reduced chemical consumption, improved health and safety, improved economics, minimized environmental impact, and improved product quality.
