Acid/Solids Separation

The accumulation of suspended solids in process tanks, pumps, and piping can significantly decrease the working life of an acid solution. To address this issue, it is important to continuously remove these solids. With an understanding that the filtration requirements can vary greatly between finishing processes, Scanacon has established a comprehensive portfolio of proprietary acid filtration systems. Each system has been meticulously engineered to provide optimal solids removal while minimizing acid loss and water consumption. By utilizing these advanced filtration systems, companies can ensure the longevity and efficiency of their acid processes.

 

AFM - SCANACON ACID FILTRATION MODULE

The AFM (Acid Filtration Module) is a highly effective filtration solution that is ideal for mixed or single acid processes where the concentrations of suspended solids are low to moderate, such as in the pickling of cold finished stainless tubular products and fittings, pickling of stainless welded parts, and titanium and zirconium pickling and chemical milling processes.

The AFM utilizes a series of woven thermoplastic fabric elements that are automatically cleaned using a back-pulse of water. This method eliminates the need for cartridge or media replacement and results in minimal water usage for cleaning, making it a superior alternative to traditional cartridge or media filtration methods.

In addition to its operational benefits, the AFM offers several significant savings, including the elimination of bottlenecks and improved productivity, reduced energy and resource consumption, decreased chemical usage, improved health and safety, enhanced economics, minimized environmental impact, and improved product quality.

ASRA – HIGH SOLIDS REMOVAL SYSTEM

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.

ASRA-SAFU

The ASRA-SAFU filtration system is designed to handle high volumes of suspended solids in HNO3-HF processes, making it ideal for a range of applications, including hot-rolled products and cold-rolled products with higher solids concentrations. This two-stage filtration system leverages the best of two proven filtration methods – ASRA sludge removal and cross-flow microfiltration – to deliver a continuous filtration solution that is both highly efficient and effective.

With its advanced design, the ASRA-SAFU can handle high total suspended solids feeds, ensuring that even the toughest filtration challenges can be met. Additionally, the system can operate at temperatures up to 60C and delivers a filtrate quality of 1 micron, making it ideal for a wide range of finishing processes for flat rolled, tubular goods, and long products.

Furthermore, the ASRA-SAFU is designed to minimize acid loss and waste-water generation while delivering a highly filtered solution. This, in turn, helps to reduce costs and minimize the environmental impact of the filtration process.

STAND-ALONE ASRA

The ASRA is a specially designed filtration system for mixed acid and single acid processes with high concentrations of suspended solids. It is engineered to remove these solids directly from the finishing process, making it a highly efficient and practical solution for hot rolled and annealed stainless and titanium flat products pickling, de-glassing, and pickling for stainless extruded products.

The ASRA operates at high temperatures thanks to its woven thermoplastic fabric elements, HF-proof fiber-reinforced housing, and PVDF piping. This makes it a reliable solution for sulphuric acid pickling. Its compact modular design, low waste generation, and ability to produce a low-moisture solid filter cake without moving plates make it a superior alternative to traditional filtration technologies such as filter-press.

Using the ASRA can bring several benefits, including reducing bottlenecks and increasing productivity, saving energy and resources, decreasing chemical consumption, reducing health and safety liabilities, improving economics, minimizing environmental impact, and enhancing product quality.
