What micron rating should I specify for sanitary liquid filtration?

For most pharmaceutical and beverage streams, 0.2–5 µm absolute-rated cartridges balance sterility and throughput; validate against your worst-case particulate load and CIP cycle.

How do I verify extractables compliance for 316L filter housings?

Require a documented extractables study to USP / and confirm the housing elastomer (EPDM or FKM) is listed in the validation package.

Chemical Liquid Filtration Systems for KOSA Medical: purity and throughput with 316L stainless steel

How KOSA Medical helps chemical operators specify 316L stainless steel liquid filtration — purity and throughput with full compliance (ISO 15848, chemical compatibility, ATEX).

As a process engineer with over fifteen years at KOSA Medical, I've seen firsthand the critical role that corrosion resistance and fugitive emission control play in chemical and petrochemical industries. Our liquid filtration product line, encompassing sanitary filter housings, cartridges, and membrane systems, addresses these pain points head-on. Let's dive into the specifics of how our products meet and exceed industry standards, ensuring your processes run smoothly and safely.

Alloy Selection for Unmatched Corrosion Resistance

At KOSA Medical, we prioritize material selection to combat corrosion. Our filter housings are crafted from 316L stainless steel, renowned for its corrosion resistance in harsh chemical environments. This alloy, coupled with our precise manufacturing processes, ensures that our products can withstand exposure to a wide range of chemicals without compromising integrity. For applications requiring even higher corrosion resistance, we offer housings in other alloys, such as Hastelloy® and Inconel®, tailored to specific chemical compatibility needs. The housing alloys are selected based on stringent chemical compatibility testing, ensuring compliance with ISO 15848 standards.

Fugitive Emission Control in Filtration Systems

Fugitive emissions are a significant concern in high-purity industries. Our filter housings are designed with precision machining and tight tolerances to minimize leakage points. We adhere to ASME BPE 2019 and 3-A Sanitary Standard 2022 guidelines, ensuring our products meet the highest standards for hygienic design and performance. Our cartridge seals are engineered to provide reliable, long-term performance, reducing the risk of fugitive emissions. For example, a contract filler we worked with was struggling with frequent leakages in their filtration system, leading to downtime and product loss. By upgrading to our corrosion-resistant housings and high-precision cartridges, they achieved a significant reduction in fugitive emissions, improving their operational efficiency.

Filter Cartridges and Membrane Systems for Precision Filtration

Our filter cartridges and membrane systems are designed to meet the demanding requirements of chemical and petrochemical processes. We offer a range of filter media, including pleated filters, membrane filters, and depth filters, each tailored to specific filtration needs. Our cartridges are available in various micron ratings, from 0.2 µm absolute-rated filters to coarser options, ensuring precise filtration for your application. All our filter media are tested to ensure <1 ppb extractables, guaranteeing the purity of your process streams.

Standards and Certifications That Matter

Compliance with industry standards is non-negotiable. Our products are designed to meet or exceed relevant standards and certifications. Here are some key ones:

ISO 15848: We ensure our products meet this standard for fugitive emissions.
ATEX: Our products are certified for use in explosive atmospheres, ensuring safety in hazardous environments.
ASME BPE 2019: Our designs adhere to these biomaterial standards, ensuring compliance with bioprocessing requirements.
3-A Sanitary Standard 2022: Our filter housings meet this standard for sanitary design, crucial for food and pharmaceutical applications.

Ensuring Efficiency and Recovery

Efficiency and recovery rates are crucial in chemical and petrochemical processes. Our membrane systems are designed to achieve >99.9% recovery, minimizing product loss and maximizing efficiency. We use advanced membrane technologies that ensure high flux rates and low fouling, reducing maintenance and downtime. Our systems are also designed for easy cleaning and sterilization, further enhancing operational efficiency.

I invite you to discuss your specific application with our team of experienced application engineers. We're here to provide technical expertise and tailor our solutions to meet your unique needs. Together, we can ensure your filtration systems operate at peak performance, minimizing corrosion and fugitive emissions.
