Depth filtration is a multi-layered filtration process that involves passing a liquid through a porous medium to capture suspended particles and impurities. The filtration media used in depth filtration is crucial in achieving efficient and effective separation. The media is designed with different properties to cater to specific applications, providing diverse capabilities for particle retention and liquid flow.
- Composition: Depth filtration media is composed of various materials, such as cellulose fibres, diatomaceous earth, perlite, activated carbon, and polymeric materials. The combination of these materials in different layers forms a depth filter matrix.
- Porosity: One of the fundamental characteristics of depth filtration media is its porosity. The porous structure allows the liquid to pass through the media while trapping contaminants. The porosity of the media is determined by the size and distribution of the pores, which can be tailored based on specific particle size requirements.
- Gradient Density: Depth filtration media typically exhibit a gradient density, meaning the pore size decreases progressively from the inlet to the outlet side. This gradient structure enhances the filtration efficiency by capturing larger particles near the surface while retaining smaller particles deeper within the media.
Applications of Depth Filtration Media
Pharmaceutical Industry: Depth filtration media is extensively used in the pharmaceutical industry for the clarification of process liquids, removal of particulates, and purification of active pharmaceutical ingredients (APIs). The media’s fine particle retention capability ensures the production of high-quality drugs and avoids contamination.
Food and Beverage Industry: In the food and beverage industry, depth filtration media plays a vital role in removing suspended solids, yeast, bacteria, and other impurities. It is commonly used for the filtration of juices, alcoholic beverages, edible oils, beer, and wine, ensuring product stability, clarity, and taste.
Chemical Industry: Depth filtration media finds applications in the chemical industry for the separation of catalyst particles, purification of solvents, removal of pigments, and clarification of process liquids. It assists in maintaining product quality and extending the operational life of equipment.
Advantages of Depth Filtration Media
Efficiency: Depth filtration media can achieve high particle removal efficiencies, with the ability to capture particles ranging from a few microns to several hundred microns. The gradient density design enhances filtration performance and prolongs filter life.
Capacity: Due to the multi-layered structure, depth filtration media has a large dirt-holding capacity compared to other filtration methods and media. This allows longer filtration operation without frequent filter replacements, reducing downtime and associated costs.
Flexibility: Depth filtration media can be customized based on specific application requirements. The composition, porosity, and gradient density can be tailored to address variations in particle size, liquid flow rates, and filtration performance.
Cost-effectiveness: Compared to other filtration methods such as membrane filtration, depth filtration media offers significant cost advantages. It is generally more affordable, and the longer filter life reduces maintenance expenses considerably.
Depth Filtration Media: Product Overview Synopsis
The following represents merely a SYNOPSIS of our range of depth filtration media. In addition to a diverse portfolio of filter sheets, various types of filter paper are also available, such as activated carbon filter paper for electroplating, wet strength filter paper, high viscosity fluid filter paper, fine particle filter paper, creped filter paper, oil filter paper, frying oil filter paper and many more.
Lipid removal
This series filter sheets are specifically designed for blood products. These filter sheets possess exceptional lipid removal capabilities, effectively eliminating lipid residues in blood. With high-quality materials and precise design, they ensure the stability and reliability of filtration, allowing blood products to be handled with ease. Whether used for blood transfusion, plasma preparation, or other blood processing procedures, this series filter sheets are a reliable choice, providing users with efficient and pure blood products.
Support sheets for beer and beverage
This series is a new type of washable, reusable support sheet for pre-coat filtration in diatomaceous earth frame filters, for extremely high reliable filtration performance in the food and beverage industry. These filter sheets only serve as precoat support, while the kieselguhr or other filter aid performs the actual filtration and separation. Its high wet strength and optimized surface enable a service life up to 30 precoat cycles, depending on the liquid to be filtered and the filter aid used.
Specification and Specific Advantages of the SCP series
Robust sheet surface for increased sheet life and heavy-duty use, innovative sheet surface for improved cake release
Extremely durable and flexible, perfect powder retention capacity and lowest drip-loss values
Available as folded or single sheets to fit any of the filter press sizes and types
Very tolerant of pressure transients during the filtration cycle
Flexible collocation with various filter aids e.g. kieselguhr, perlite, activated carbon, polyvinylpolypyrrolidone (PVPP)
Primary Applications
Beer, food, fine/specialty chemistry, cosmetics.
