When it comes to wet filtration, our customers always have plenty of questions; and as an expert in engineered filtration, Micronics is always happy to answer any filter cloth selection questions you may have. Today we’re addressing one of the topics we get asked about most often, and that is around filter cloth, one of the key ingredients to an efficient, cost-effective filter press operation.
How Filter Cloth Selection Can Make a Major Difference in Your Filter Press Operation
Home > How Filter Cloth Selection Can Make a Major Difference in Your Filter Press Operation
Our customers come from a wide range of industries, so they’re frequently asking how the choice of filter cloth will impact their unique operation. Perhaps you are wondering this very same thing. Take a moment to review the filter cloth fabric options available to you, and the innovative processes we employ in filter cloth manufacturing at Micronics. As you read, you might get an idea of what characteristics you are looking for to optimize your filter press operation, so we can design a custom filter cloth that exceeds your performance expectations.
Yarn Fiber Materials, Filament Types & Yarn Designs
It all starts with our process of examining your unique application, then combining yarn and fiber types with weave patterns. Our years of textile expertise has allowed us to develop customized recommendations for fibers/yarns for any application from mining to chemical manufacturing. Yarn designs and weave patterns are another critical element, as are sewing choices, edge treatments, and feed necks. Each of these elements contributes to the precisely right cloth for your application. Micronics works with you from the ground up to deliver the filter cloth that achieves what you need from particle retention to improved cake release to drier cakes to longer cloth life and more efficient filter press operations. The yarn fibers we work with are typically produced from the most advanced materials like Polypropylene, Polyethylene, Polyester, Polyamide (Nylon) and Rilsan®.
Weave Patterns and the Weaving Process
The weaving process – including weave patterns – plays a very important role in the manufacture of standard and custom filter cloth. It all comes down to how the yarn is produced. First, synthetic resins are extruded, forming multi-filament or continuous filament yarns. The filament bunches are then twisted together to form the yarn. The tighter the filaments are twisted, the less potential for the resulting yard to retain particles in the filtration process. Multifilament yarns offer a high tensile strength and average particle collection efficiency, so filter cake release is average. Mono-filament yarns are produced with heavier extrusions which are smooth and offer a high tensile strength. In some cases, they are modified with fillers. Our experts will help in the evaluation of various cloth selection considerations including factors such as resistance to chemical attack, thermal properties, and abrasion resistance so that the filter cloth you receive is precisely right for your unique set of operating conditions.
Laser Cutting, Feed Necks, and Edge Sealing
When it comes to filter cloth, the details make all the difference. Technological innovation is important at Micronics where all our filter cloth is precision-manufactured with state-of-the-art laser cutters. Feed necks are another important parameter that greatly affects filtration performance and Micronics offers many options from welded HPR design to a patented, Micronics-designed clip neck. In addition, our proprietary latex edge sealing operations play a critical part in increasing the durability and life of the filter cloth. With Micronics, our innovative filter cloth fabrication processes ensure that our cloths deliver excellent cake discharge, long life and are easy to clean and change-out.
When we say “custom filter cloth” we really mean it. When you come to us to describe your needs, we will create the ideal filter cloth for your filter press operation.
