Pure Spring Pools™ Pola Filtration

Nanofiltration describes a filter process with a membrane that will filter out anything larger than 1 to 10 nanometers, depending on the pore size in the membrane. This membrane technology is only a small step below reverse osmosis.

By using Pure Spring Pools™ Pola technology, nanofiltration can be accomplished with a
sand filter.
Pure Spring Pools™ offers sand filters that ensure the very best water quality. The filters
feature:

• deep filtration bed
• self-cleaning activated carbon (when used with PolaAktive)
• proprietary media layering
• reduced backwashing
• ample freeboard for reduced turbulence and better flocculation

Benefits:

• crystal clear water ( <0.05 NTU is typical )
• lowered combined chlorine
• lowered operational costs
• less wasted water
• physical barrier to pathogens (when used with a flocculant)
