Cartridge Filter Application Form
Cartridge Filter Application RFQ

This form is to identify the appropriate cartridge filter for new application and after market filter cartridge replacements.  Please provide OEM nomenclature and part number whenever available. At the completion of the form please provide as much information as possible regarding the vessel make & model, and describe the filtration process as well as any issues presently being experienced.

Accurate information and enhanced communication is critical at conception to avoid high post installation filter costs. Complete multiple forms for each filter cartridge requirement or application.

REQUIREMENT: New     "Equal Too"   Upgrade  

*The following information is required to provide "equal too" filter cartridge alternatives, process improvement costing reductions, and the data required to explore and model various cartridge filter vessel and media combinations to aliviate post installation high filtration costing values. Providing this information enables us to provide you with "performance equal" alternatives.

*Differential pressure available to load the filter (psig)?
*Most filter cartridges are optimized when they have ample pressure available to develop between a 30-50psi debris capture load. Simply stated this pressure value is the difference between clean and terminal differential pressures whereas: should a clean differential pressure be 10psi for example this would allow the cartridge to load an additional 20-40psi, thus this would be considered by most to be a somewhat reasonable costing efficiency.  Should the pump produce any pressure less than the 20-40psi one would be replacing the filter cartridges prior their maximum debris loading capacity thus higher filtration costing.

Type of Pump:
*The type of pump is critical to filter performance, debris holding capacity, and unloading. To optimize a filter cartridge and reduce total filtration costing pump flow characteristics and its influence upon a filter system must be acknowledged. In the space below please provide as much information about the existing pump and driver.  With this data we can plot performance and make recommendations that will dramatically effect total filtration costing values.

Process Duty Cycle:Continuous Batch    Batch Volume
*Determining filter life cycle and which technology best complements the filtration process will naturally surface only when the volume/time relationship has been identified.  Given a continuous process obviously the least interruption for change would be the more desirable while having a filter system that is at 50% of its terminal life when a batch is completed would be inefficient use of a filter cartridge and poor spending economics. Some applications while batch may be able to keep the filters "wetted" between batches thus fewer filter changes while others may be better suited parallel on/off line systems. In space below please describe the present duty cycle of the current system.  Should this be a new application please provide a minimum timeline/volume for filter system sizing and technology considerations.

Debris Characteristics:
*Size, shape (being round, flat, irregular shapes, gelatinous etc...) is extremely important when selecting a filter media technology and determining filter loading which influences filter usage. Filter selection during conception in many applications is what contributes to high post installation costs, interruption for change and increased operator involvement. Provide the debris characteristics in the space provided below:

Cleanliness Targets & Validation
*To enhance communication please describe the process and the contribution of the filter system, e.g., polish already filtered product, pre-filter and protect downstream filters, reduce TSS loads for waste water, increase clarity values, etc... also, include your cleanliness target and testing QC methods used to determine filtration and solution performance and quality.
