is an easily installed side stream or process line filtration systems that remove
particulate contaminants from the cooling water down to 0.45 micron. Filtration
is 10 to 20 times finer than traditional sand filters and is designed for 0.45
micron solids removal. Vortisand provides high-performance results using a unique
concept that combines centrifugal separation and ultra-fine sand filtration.
unit uses a tangential spin across the sand to keep dirt from building up in
the unit. Using centrifugal force above the multi-layered media helps to remove
the suspended solids and significantly increases the effective filter surface
within the tank.
How it works
filtering will remove suspended solids which cause higher energy costs, biological
fouling, scaling, corrosion and legionella in your system. Vortisand provides
clean, clear water when used in conjunction with chemical treatment programs
that chemical treatment alone cannot guarantee. Greater benefits will result
from very fine contaminants removal.
studies carried out using laser particle counters have shown that 85.95% of
the particles present in the recirculation water of either closed loops (evaporator
circuit) or open loops (cooling tower circuit) are less than 5 micron in size.
Water from the cooling tower absorbs most dirt and airborne contaminants surrounding
turbulence produces a sustained cleaning action that forces the suspended solids
to accumulate near the inside walls of the tank. As a result, much finer sand
can be used without any clogging problems. The water which is now largely free
of impurities, is then filtered through the media and subsequently collected.
Contaminants trapped above the sand are removed using an automatic backwash
cycle which requires less water and a shorter operating time than traditional
sand filters. This process contributes to longer cycles and much finer filtration
