Percolite® producer Pratley has a dedicated, state-of-the-art filter aid production facility that represents the most advanced plant on the continent. Here proprietary technology is used to process Perlite raw material to ultimately produce an extremely high-quality filter aid.
Perlite is a unique, naturally occurring vitreous volcanic lava rock. The crushed material is expanded in a furnace at 950˚C to produce millions of tiny hollow bubbles. The high temperature also means that the filter aid is completely inert and sterile. It also does not impart any colour, taste, or odour into the filtrate.
These bubbles are then carefully milled using specialised production methods and accurately classified to produce the various Percolite® grades. The unique interlocking structure of Percolite® forms a myriad of microscopic interparticle channels, ensuring the product efficiently removes particulate material from the filtrate. The main advantage of Percolite® filter aid is a high flow rate combined with exceptional clarity.
“The accurate size classification and the unique structure of Percolite® filter aid leads to one of the highest flow rate to clarity ratios possible,” highlights Pratley Marketing Director Eldon Kruger. “The fundamental problem of filtration is to maximise two desirable yet conflicting parameters, namely clarity and flow rate. Percolite® achieves just that.”
The Percolite® manufacturing process is ISO 9001-2015 certified. In addition, Percolite® meets the standards listed in the food chemicals codex published by the US National Academy of Sciences. Pratley Percolite® also holds Halaal certification and the company is a member of the International Perlite Institute.
In addition, Pratley has a cutting-edge R&D laboratory supervising quality control of the end product. Sophisticated test equipment includes a laser particle size analyser, turbidity meters, X-ray diffractometer, scanning electron microscopes, viscometers, an atomic absorption spectrometer, Fourier transform infrared spectrometer and filtration flow rigs. This equipment not only ensures stringent quality control but also allows Pratley to thoroughly analyse customer liquids in order to recommend the most suitable Percolite® grade for the job.
Percolite® filter aid ranges from fine grades for absolute clarity to coarser grades with fast flow rates for maximum productivity. Grades can be manufactured and tested to meet unique customer-specific requirements. Percolite® may be used in almost any industry requiring fine liquid/solid separation:
Food & beverage: Wine, oil, starch, beer, glucose, fruit juice, syrup
Pharmaceutical: Antibiotics, enzymes, Epsom salt
Chemicals: Acids, resins, polymers, adhesives, hydrolysed vegetable protein
Industrial: Water treatment, oil and solvent recovery, industrial fillers, heavy metal solutions, industrial chemicals, platinum-bearing solutions, copper-cobalt-nickel solutions, titanium solutions, electroplating solutions, dry cleaning
