Fine Filtration and High Solids Removal in a single unit. PETAX operates continuously to filter particles as small as 1-20 microns.

The PETAX Filter uses patented technology to provide economical, single-stage filtration of liquids containing high solids content. PETAX is capable of processing up to 1056 gpm (240 m3/hr) of water with suspended solids in the range of 100-2000 mg/l.

In operation, suspended solids in the filtrate are typically less than 20 mg/l. This exceptional filtration is achieved without the addition of chemical flocculants, or fiber sweetener stock or precoats.

PETAX enables the recycling of white water on the paper machine for use in showers – even high-pressure showers on the wire or felts. Mills have been able to document up to 30% savings in water consumption on the paper machine after PETAX is installed.

In addition to the reduction in fresh water, the reduction of fines in circulation can result in a decrease of COD from the paper machine of 20-40%.
