generally recommends sidestream installation of its filter systems and its standard systems are designed and built for
sidestream application. Sidestream filtration means a filter system which draws water from and returns it to a static pressure
reservoir of water in the cooling loop, completely independent of the cooling water recirculation system. Usually, that reservoir of
water is the basin of the cooling tower or sometimes it may be a chilled water storage reservoir in the cooling loop.
However, there are occassions where a design has called for slipstream installation. Slipstream filtration means a filter which is
installed on the pressurized recirculation piping system, "slipping" a portion of the chilled water recirculation flow through the filter
system. Depending on the points of connection to the recirculation piping, the slipstream may be either under the influence of the
discharge side or the suction side of the recirculation pump.
If the filter system you are about to install is to be installed in any other fashion than sidestream, please be sure that necessary
consideration has been given to operating pressure of the filter system and flow promotion issues. If you, as the installer, have
any questions, contact your local Tower-Flo Representative or contact the Tower-Flo Water Filter Systems Division of United
Industries, Inc.
INSTALLATION STYLE
BASIN SWEEPER PIPING SYSTEM
A basin sweeper piping system will use the return flow of filtered water from the filter system to help sweep solids towards the filter's
suction point. However, it is very important to have a reasonable expectation of such a basin sweeper piping system. It must be
understood that the primary purpose of the filter system is the continuous removal of suspended solids from the water being
recirculated through the cooling loop. The basin sweeper piping system provides a secondary benefit by promoting the movement
solids across the basin floor toward the filter suction point for removal.
While such a system can reduce the time and effort required for regular basin clean-out, even the best designed sweeper piping
system cannot keep a cooling tower basin perfectly clean nor sweep effectively around all appertinances. If you plan to use a
basin sweeper piping system, please review the information on the next page to determine the proper number of nozzles or per-
forations to be used with your basin sweeper piping system.
