4 INTRODUCTION TO LIQUID FILTRATION

5 Principles of Liquid Filtration Liquid fi ltration is the removal of contaminate particles from a fl uid system. The grade of fi lter chosen for a specifi c application is usually determined by the size of the particle to be removed. Contaminant particles are measured in microns. Micron Micron A micron is a metric unit of measurement where one micron is equivalent to one one-thousandth of a millimeter [1 micron (1µ) = 1/1000 mm] or 1 micron (micrometer) = 1/1,000,000 of a meter. Visualizing a micron - a human red blood cell is 5 microns - an average human hair has a diameter of 70 microns - most humans cannot see anything smaller than 40 microns with the unaided eye The micron unit of measurement is used not only to measure the size of a contaminate particle, it is also used to measure the size of the openings in fi lter media (a media s micron rating). This system of measurement is more accurate when gauging woven fi ltration structures such as monofi laments than it is for gauging non-woven structures such as felts. SchroederSOX for Liquid Filtration Systems 5

6 Mesh vs. Micron Mesh vs. Micron Mesh vs. Micron The old standard imperial system of gauging a woven fi ltration media s ability to remove contaminate particles was the mesh system. This system simply counted the number of strands or yarns per inch of woven media, hence a 100 mesh media has 100 yarns per inch of media. This system falls short because the actual window opening of a woven structure can vary as the diameter of the yarn varies. For example, a 50 mesh fabric with a yarn diameter of 100 micron would have a window opening of 410 microns, whereas a 50 mesh fabric with a yarn diameter of 200 micron would have a window opening of 310 microns. The mesh system s main value now is in the determination of a percentage of open area in a structure, which is calculated by using the yarn diameter and the mesh count in order to determine the potential fl ow rate of a liquid through a woven fi ltration media. While the micron system attempts to measure an exact window opening for a woven media, a micron rating for non-woven media refers to exact particle size retention.

8 Liquid Filtration Media Fiber Content Filtration media, whether woven or non-woven, are constructed from either natural or man-made fi bers. Today, the only natural fi bers still used in limited applications are wool and cotton. Their primary benefi t is in their ability to withstand higher temperatures. The development of synthetic fi bers, such as polyester, polypropylene, nylon, aramid, rayon, viscose and polyethylene has all but eliminated the use of natural fi ber media in liquid fi ltration. When we select a media for a specifi c application, its fi ber content can be critical due to the fi bers ability to withstand specifi c chemical and thermal environments. Basic compatibilities are outlined in the table below.

9 Liquid Filtration Media Surface media are fi ltration structures which remove contaminate particles on the surface of the structure. They are generally two dimensional woven structures and are only as deep as the diameter of the yarn from which they are woven. They will only trap particles that are larger than the window opening of the structure. Their advantage is that they can be woven with great precision, therefore offering exact window openings, providing entrapment of particles of a specifi c size. Their disadvantage, however, is that they do not offer high particle loading or dirt holding capacity because they have little depth. As a result, they tend to plug up or blind off more quickly than their depth media counterparts. Surface Media (Mesh) Not all surface medias are woven. There are surface structures that are constructed mainly from matted fibers which are bonded together with heat or binding agents. They are commonly known as spunbonded or point bonded structures and are primarily used in multi-layer applications as covers or bypass and transfer layers due to their low inherent strength characteristics. The most widely used surface media are woven structures using either multifi lament or monofi lament yarn made from polyester, polypropylene, and nylon. Multifilament media are woven from strands or yarns consisting of many smaller strands or fi bers that have been spun or twisted together. They have the advantage of being the most inexpensive woven media, and therefore produce a very low cost disposable fi lter bag. An individual yarn may vary 50% or more in diameter and generally produce a woven structure that has a rectangular rather than a square window opening. Contaminate particles tend to get trapped within the fi bers of the yarn making this media very diffi cult to clean and re-use. Despite these shortcomings, they are well suited to a great many fi ltration applications where high precision is not required and low cost is key. Monofilament media are woven from strands or yarns which have been extruded from a polymer and therefore have a consistent diameter and a very smooth surface. The advantage of this type of yarn is that they weave a very precise fi ltration structure with consistent square window openings. The yarn s smooth surface enables it to be cleaned and reused in many applications. Monofi laments offer precision rated media with high mechanical strength. Depth media are fi ltration structures which remove contaminate particles both on the surface and within the depth of the media. They are typically of needled felt or melt blown construction in a three dimensional structure. This creates a tortuous path for particles to follow, often resulting in particulate of a size smaller than the actual pore openings being trapped within the structure. Depth Media (Felt) The advantages are high dirt holding capacity, higher void volume or pore volume, the capability of removing gelatinous particles and particles smaller than the mean pore openings, and most importantly, a long service life due to the three dimensional structure.

10 SOX ELEMENTS AND SOX HOUSINGS

11 Sox Elements There are two basic types of Sox filter systems, open and closed. Open System This is the most economical socks filter system consisting of a micron rated socks filter, which is simply tied onto a pipe or secured to an adapter head that is threaded onto a pipe through which unfiltered liquid passes. An open system also includes a strainer bag into which unfiltered fluid is poured (ex. a strainer bag placed into a 5 gallon pail). Open & Closed Systems Closed System This is an economical method of liquid filtration consisting of three main components: micron rated sock filter retainer basket pressure vessel The liquid to be filtered is delivered through the inlet of the filter vessel into the top of the sock filter, which is supported by the retainer basket. Because the system is pressurized, the liquid is distributed evenly over the entire surface of the sock filter resulting in even flow distribution. In both open and closed systems, the fluid passes through the sock filter from the inside out. Contaminate particles remain inside the sock allowing sock filter change-out to take place without contamination of the filtrate. Absolute & Nominal The terms absolute and nominal are often associated with micron ratings given to liquid Sock filter and cartridges. Absolute & Nominal As the name suggests, absolute conjures up a notion of 100% pure filtration. Absolute rated sock filter and cartridges, contrary to their name, are not absolute. They are generally gauged by the percentage of contaminate particles they are capable of removing in perfect laboratory conditions. For example, a one micron absolute rated sock filter will remove between 99.5% and 99.9% of laboratory challenge particles one micron or larger. They are not 100%. For this reason, we refer to this type of sock filter as high efficiency, stating the corresponding media efficiencies from independent laboratory test results. On the other hand, nominal micron ratings are average or general in nature. Their efficiencies can fall anywhere between 50% and 95% with the norm being around 80% efficiency. That is to say, a one micron nominally rated sock filter will remove approximately 80% of challenge particles one micron or larger in perfect laboratory conditions. The terms absolute (high efficiency) and nominal should be used as a guideline only when selecting the best sock filter or cartridge for an application. Unless stated as high efficiency or absolute micron ratings used in the SchroederSOX part numbering system are nominal. SchroederSOX for Liquid Filtration Systems 11

12 Sox Elements Schroeder offers a complete line of sox filters and housings to fit a wide variety of applications. From single sox housings to high flow multiple sox housings, Schroeder has an economical filtration solution to fit nearly any application. The disposable sox elements offered by Schroeder Biofuels come in a wide variety of materials, sizes and styles. Our standard socks include a steel ring collar that acts as both a gasket to securely seal the sock to the housings as well as to support the sock while in operation. The ring is also available in stainless steel, with a draw string or with a plastic sure seal ring that has integrated handles. Mono or multifilament are used for more coarse filtration. Felt socks are either singed or glazed to prevent fiber migration on the clean side of the filter/strainer. Our socks are made in standard industry sizes from 1 through 12. We also have commercial size bags available with a snap band support ring. The seams on the socks are either sewn or welded depending upon the systems requirements. Welded socks offer: No needle holes No thread migration Strong, even sealing of the material Sox Operating Guidelines Essential Questions To Ask When Sizing A Sox System Our sox systems provide efficient and economical filtration. Some advantages to sock filtration are: Positive seal to assure zero fluid bypass Quick and easy installation Handles provide easy removal from housings High dirt holding capacity Sturdy construction to prevent socks from failing in operation 100% incinerable Recommended change-out: It is recommended that a liquid filter sox be changed out when the differential pressure ( P) between the upstream and downstream sides reaches psi. Although this is a rule of thumb, some applications may require change-out at a P well below 20 psi. Under no circumstances should P be allowed to exceed 25 psi. What is the product that needs to be filtered? Obtain all the details of the liquid/solid composition. You need to confirm the chemical compatibility to ensure the proper material is used for the sock, retainer type, and the housing for the socks. What is the viscosity of the product to be filtered? Use a flow chart to find out the optimum operating parameters. What is the ph level in order to choose the proper material for the filtration system? Is the product an acid with a ph of 1-7 or is it Alkaline 7-14? What type of solids does the product contain? Are the solids crystalline or gelatinous? Crystalline solids can form a permeable layer on the filter media and gelatinous solids can form an impermeable layer that will cause blinding off of the filter media. What is the density of the solids? 12

13 Sox Elements What is the PPM (parts per million) of the solids? What is the range of particle size? What size does the customer want to remove and at what efficiency? The range of particulate size is important in determining which micron rating your filter media should be. Filter socks can be made with nominally rated material or with high efficiency material. Essential Questions Cont. What is the flow rate of the product? The flow rate is critical information required when determining the size and number of socks required. Is it a continuous or batch process? This is important in order to determine the filter sock consumption and plumming configuration. What is the operating pressure of the system? At what minimum and maximum potential pressure is the system designed to run? What is the acceptable pressure required? Filter sock differential pressure capacity is psi. What is the temperature of the product being filtered? Temperature has an impact on the viscosity, the filter media and the O-rings. The temperature can even affect the corrosion rate of the housing.

For high contaminant loading applications, this value should be as low as possible. The lower the value is, the more contaminant a sock will hold. For applications with nominal contaminants, this value can go to 3.0 psi (0.21 bar) or more. Consult factory for specifi c recommendations when the clean PS exceeds 2.0 psi (0.14 bar). 14
