Filters with nonfixed pores may also be subject to mediamigration allowing filter media to pass into the filtrate. Filters with fixed pore structure should be used for all filtration stages downstream of primary filtration. Such filters may be characterized by a ßratio value which is an objective measurement of particulate removal efficiency.

Often customers attempt to increase filtration throughput by choosing a coarser grade of filter aid only to find out the filtration performance has been negatively impacted.

How Filteraid Works

The selection of the proper filter aid grade is a compromise between high clarity and low flow rate, and lower clarity and higher flow rate. The best filter aid is that grade which provides the fastest flow rate while maintaining an acceptable degree of clarity, which must be determined and specified by the filter aid
