Before Ordering a Custom Cartridge Filter Housing: 7 Details to Prepare

When a standard cartridge filter housing does not match an industrial installation, customization may be an option. But before requesting a quotation, it helps to provide the manufacturer with clear information about the equipment and process. The more accurately the requirements are described, the easier it is to assess a suitable configuration. Here are seven details worth preparing. 1. Existing Housing Dimensions For a replacement project, record the overall height, diameter, available installation space, and any dimensions that affect mounting or maintenance access. If possible, provide photographs from different angles. A nameplate or existing equipment drawing can also help identify the current configuration. 2. Connection Type and Position Specify whether the connections are threaded, flanged, or clamp type. Include connection sizes and, where relevant, the inlet and outlet positions and orientation. These details can be particularly important when the existing piping is diffic...

What Should You Consider Before Choosing a Stainless Steel Cartridge Filter Housing?

Stainless steel cartridge filter housings are widely used in industrial liquid filtration, but choosing the housing material is not simply a matter of selecting the higher stainless steel grade. SS304 and SS316L are both common choices. The appropriate option depends on the process environment, fluid compatibility, cleaning conditions and project requirements. In-depth Reading → Industrial Cartridge Filter Housing Guide 1. What Is the Process Fluid? Start with the fluid that will contact the housing. For relatively non-aggressive industrial fluids, SS304 may be suitable. If the fluid or surrounding environment presents a greater corrosion risk, SS316L may need to be considered. The material decision should therefore begin with the actual process rather than the material price or grade alone. 2. Is Chloride Exposure a Concern? Chloride exposure is an important consideration when comparing 304 and 316L. SS316L generally provides better resistance to chloride-related pitting and crevice ...

Industrial Security Filtration: Applications, Process Role and a 300 m³/h Case

Industrial security filtration is commonly used when a liquid requires additional particle control before a downstream process or sensitive piece of equipment. Unlike a primary filtration stage that may handle a larger solids load, security filtration often serves as an additional barrier after upstream treatment. A simple process concept is: Primary filtration → Security filtration → Downstream process The actual arrangement depends on the liquid and process requirements. 1. Water Treatment In industrial water treatment, a security filter may be installed after upstream filtration and before RO, UF or other downstream equipment. Its purpose is not to replace pretreatment, but to provide additional control of residual particles. This can be particularly relevant when downstream membranes or equipment require more controlled feed conditions. In depth Reading: Industrial Security Filter for RO Systems 2. Seawater Treatment Seawater desalination systems can also use additional filt...

How a 12-Bag Filter Housing Improved Fruit Juice Clarification

Fruit juice clarification often involves more than choosing a suitable filtration rating. The amount of suspended material, available filtration area and frequency of filter maintenance can all affect the way a filtration system performs in daily production. A fruit juice processing project in Guangdong, China illustrates this point. From Plate-and-Frame Filtration to a Multi-Bag Housing The plant was previously using a plate-and-frame filtration system. Fruit pulp residues and cellulose fibers accumulated on the filter cloth during operation, resulting in frequent cleaning and additional operator work. For the upgraded system, YuanLv Filter supplied a YDS-D12 12- bag filter housing . The housing contains 12 filter bags operating in parallel. This configuration provides a larger combined filtration area while keeping the filtration media inside one housing. The system was used during juice clarification to remove fruit pulp residues, yeast cells and suspended particles. Project R...

What Information Should You Provide When Buying an Industrial Security Filter?

When requesting an industrial security filter , sending only the pipe size or required micron rating is usually not enough. A filter manufacturer needs to understand the process conditions before recommending a suitable configuration. For the product detail, to What Is an Industrial Security Filter Here are the main details worth preparing. 1. Process Fluid Start by identifying the liquid being filtered. For example: Industrial water Seawater Chemical solutions Process liquids Food and beverage liquids High-purity water The fluid can affect housing material, filter element material and the overall configuration. 2. Required Flow Rate Provide the normal operating flow whenever possible. If the process has significant flow fluctuations, peak flow information is also useful. Flow requirements affect the practical filter capacity and configuration. 3. Required Filtration Rating The required filtration rating should be connected to the actual particle-removal objective. A smaller micron rat...

Where Should a Security Filter Be Installed in an RO System?

Where Should a Security Filter Be Installed in an RO System? One of the most common questions in industrial water treatment is where a security filter should be located within an RO process. For a broader explanation of industrial security filtration, see Industrial Security Filter: Types, Applications and How It Works . Although every system is different, a frequently used arrangement is: Raw Water → Pretreatment → Security Filter → High-Pressure Pump → RO Membrane In this configuration: Pretreatment removes the primary contaminant load. Security filtration provides additional control of residual particles. Sensitive downstream equipment receives a cleaner feed stream. This approach allows each treatment stage to perform a specific role. Security filtration is commonly applied in: Industrial water treatment Desalination facilities High-purity water production Chemical process water systems Food and beverage applications When selecting a security filter, engineers generally evaluate: ...

Self-Cleaning Filter Selection: A Practical Industrial Guide

Selecting a self-cleaning filter for an industrial process requires more than choosing a filtration rating. The correct configuration depends on the liquid being filtered, contaminants, flow rate, operating conditions and the cleaning method. Here is a practical way to approach the selection. 1. Identify the fluid Start by identifying the process liquid. Typical applications may involve: Industrial water Cooling water Wastewater Process liquids For some applications, viscosity and corrosiveness should also be considered. 2. Identify the contaminants Determine what the filter needs to remove. Common contaminants include sand, sediment, rust, suspended solids and mechanical impurities. It is also useful to understand the solids loading and physical characteristics of the contaminants. 3. Determine normal and maximum flow Flow rate should be considered under actual operating conditions. Both normal and peak flow should be provided when evaluating a filter. Selecting equipment only accord...

Refinery Wastewater Pretreatment: A Basket Filter Application in Russia

A practical refinery wastewater case showing how upstream basket filtration can remove oily sludge and suspended solids before biological treatment. Refinery wastewater can contain a combination of suspended solids, oily sludge and other process residues. When the solids load is high, removing part of it before biological treatment can help improve the stability of the downstream process. A wastewater pretreatment project at a Russian refinery provides a practical example. The Initial Situation The refinery was handling wastewater containing significant amounts of oily sludge and suspended solids. The concern was the impact of these contaminants on the downstream biological treatment stage. If larger solids and sludge continued into the biological process, they could increase the operating load and contribute to problems in equipment such as aeration tanks. The customer therefore needed an upstream filtration stage capable of removing larger contaminants before biological treatment. Th...

Cartridge Filter Element Selection: 7 Factors to Check Before Ordering

Choosing a cartridge filter element for an industrial system requires more than selecting a micron rating. The following seven factors can help organize the selection process. For an overview of housing types, configurations and selection factors, see our Industrial Cartridge Filter Housing Guide . 1. What needs to be removed? Start with the contaminants. Identify the type of particles and the required filtration result before choosing the element. 2. What micron rating is required? The micron rating should reflect the actual filtration requirement. A finer element isn't automatically the best option. It can increase flow resistance and may require more frequent replacement when the filtration requirement does not justify it. 3. What is the process fluid? Water, chemicals, oils and process liquids may require different filter materials. Chemical compatibility should be checked for the filter media, support structure and sealing components. 4. What is the required flow? Flow rate a...
