How Clean is your cooling water?


Particles responsible for fouling of heat transfer surfaces are smaller than 5 microns. Pakwater Care services high efficiency filters remove these extremely fine particles to provide the true benefits of clean cooling water.

High Efficiency Sand Filters

The development of high efficiency sand filters has revolutionized cooling water filtration. Suspended solids can now be cost effectively removed to 1/2 micron with an automatic backwashing filter. Older technology multimedia filters only get down to about 10 microns. Since most cooling water particles are in the 1/2 to 5 micron size range, high efficiency filters are much better at removing these troublesome contaminants. More efficient filtration means greatly improved results with a smaller filter.

Pakwater Care services high efficiency filters use ultrafine sand to provide this much more effective filtration. The crossflow action of the water across the surface of the finer media prevents rapid plugging by pushing contaminants over to the storage area. Not only do filtration efficiencies improve dramatically, but the filters require up to 10 times less backwash water.

Cost Effective Filtration

Pakwater Care services high efficiency filters are much more efficient at removing the extremely fine particles that cooling towers scrub from the air. This greatly improved effectiveness allows these filters to be sized 4 to 5 times smaller than multimedia filters while providing much cleaner water. Multimedia filters sidestream 5 to 10% of the recirculation rate, while high efficiency filters only need 1 to 3%. Don’t waste money on large inefficient filters utilizing old technology.
