Control
Deposits - The
Triangular Wave Bypass Deposit Control System controls deposits, bacteria,
and algae in recirculating water applications. The key to the
viability of the Bypass Deposit Control System is the long lasting
treatment effect of the Triangular Wave Deposit Control System and the
IonGuard Purification System.
Many existing water-fed applications could be retrofitted with TWT
standard deposit
control devices. The TWT Bypass Deposit Control System is designed for those
applications which do not lend themselves to direct installation of a Triangular Wave
Deposit Control System. Possible reasons for this include: incompatible pipe material,
inadequate pipe arrangement, and very large pipe diameters. In most cases, it is less
expensive to install a Bypass System than to install a large diameter Triangular Wave
Deposit Control System.
In
recirculating water applications, it is possible to treat the total volume
of water in portions, instead of equipping to treat the whole volume
at once, which can require a large investment. With a TWT
Bypass System, the deposit control effect is maintained
continuously, as long as
all of the water is treated, on average, once every eight hours or less. The
Bypass System acts as a recirculating side-stream, using standard,
smaller diameter pipe connections to eliminate the need to match
treatment equipment to expensive large diameter existing pipes.
Control
Bacteria and Algae - The
Triangular Wave Bypass Deposit Control System controls bacteria and algae
with the IonGuard Purification System, which is an electrolytic
copper-silver ion generator. The system contains specifically cast
copper/silver alloy electrodes. A small DC current (1 amp or less)
is transmitted between the two electrodes; causing copper and silver ions
to plate off into the water. The copper ions kill algae, and the
silver ions kill bacteria.When the
IonGuard Purification System is used in conjunction with a filter, the dead bacteria
with the silver ion attached to it, will be large enough for the filter to
remove. If installed where no filter is used, it will be removed from the tower system during a regular controlled bleed.
The criteria for copper and silver in water are as follows: The EPA standard for drinking water
is 1.0 ppm (parts per million) maximum for copper and 50 ppb (parts per billion) maximum for
silver. The IonGuard Purification Systems are programmed so that a water test showing 0.15
ppm to 0.25 ppm copper automatically provides the proper ratio of silver. This will produce
drinking water quality in any water system treated. The IonGuard
Purification Systems require no chemicals in their function of controlling algae and bacteria.
The IonGuard Purification System is powered by a "current source" power supply. All other
ionization units are powered by "voltage source" power supplies. In an ionization unit, copper
and silver ions plate off of the electrodes and enter the water. Over time, the electrodes will
become smaller, and the gap between the electrodes will become larger. The current source
power supply will automatically compensate for the change in gap size; while the voltage source
power supplies must be manually inspected and adjusted. The current source power supply on
the Triangular Wave IonGuard Purification unit offers trouble free operation. Note:
In conjunction with using the TWT Bypass System for treatment on the
recirculating line, you can obtain complete, end-to-end fluid
treatment benefits by installing an additional TWT Deposit Control
System on the makeup line to the tower. Products for small
