High Purity Filtration

Big Brand Water Filter PURE series food, beverage, lab and pharmaceutical filter housings and filters are designed for use in food, beverage, laboratory, pharmaceutical, biotech and other high purity applications.  These systems feature high purity plastics or 316 grade stainless steel filters housings and wetted parts. 
These systems are designed for applications where high quality Big Brand Water filtration low extractables filters when combined with high purity smooth inner pipe to prevent microbial growth we can meet the most stringent applications.

Multi Stage Filtration
We commonly filter to 0.2 micron absolute for most food and beverage applicatoins but can even go smaller.  The final filters are membranes, picture a piece of plastic wrap with a bunch of tiny holes, very precise at 0.2 micron but no depth filtration.
So we start with something like our Meltblown Absolute 1 micron filter wtih 99% efficiency, then a 0.5 micron meltblown.  Or if flow rate is a concern we have 90% and 99.8% reduction PURE pleated polypropylene caged filters with core all the way down to 0.2 micron.  These offer a much higher flow rate than melt blown at an additional cost.  We try to remove 99+ percent of the suspended solids with these different melt blown and pleated filters so the membrane filters last longer.  A polyethersulfone final filter costs start at over $100 each and with raw tap water could potentially clog in a day to a month, whereas with our multi stage our goal is to make the final filer last 6 months to 12 months.  We have PES, nylon, and teflon membrane filters.  Addationally stainless steel mesh filters that are cleanable, often used in high temperatures, oils and other heavy industrial applications.
