not break up into ions when dissolved in water. There are different approaches to determine TDS,
but it is commonly estimated from conductivity.
Total hardness: This is the sum of Ca and Mg hardness. Fe (Iron), Mn (Manganese), Al
(Aluminum) and other metals also contribute to the total hardness but these substances are usually
present in such small quantities that they can be ignored. Hard waters are generally considered to
be those waters that require considerable amounts of soap to produce a foam or lather, and that also
produce scale in hot water pipes, heaters, boilers, and other units in which temperature of water is
increased materially.
Transducer or Transmitter- Pressure transducers are also called transmitters and they act like a
variable resistor to a DC Voltage that is sent to the PLC. As the pressure increases the voltage that
is released by the transmitter increases, while as the pressure decreases the output voltage also
decreases.
Transformer- A transformer is used to convert one type of AC voltage to another. You can have
step up and step down transformers. Some CHC systems used primarily step down transformers to
convert the electrical supply voltage (normally 480V 60 HZ in the US) to a lower stepped down
voltage to use for the control circuit's supply (normally 120 VAC). Transformers are rated for a
voltage and should only be replaced with equivalent parts. All CHC motor starter boxes with a
timer, contain a 100VA, center tapped transformer that creates 120V from the 480 Volt supply.
Older Older cabinet style CHC units utilize a 50VA transformer, that creates 24VAC from the 480
Volt supply.
Turbo Disks- Verify similar to ZGF systems these automated filtration systems also strain out
debris from the filtration water flow. They also conduct automated back washes to remove debris
from the filtration disks.
Uses of the CHC Technology- The technology not only has applications in water treatment, it has
also been found to be beneficial in many other possible applications from mixing to treatment of
human waste to oil processing. These other uses continue to be researched and will be defined in
the future. The strongest use of our technology can be found in the Water Tower Treatment.
Cooling towers and Condensers are the primary users of our technology when we talk about Water
Towers.
Water Analysis- The water analysis is a chemical analysis of the water sample taken from the
customer's location. The results of this analysis will be returned to the appropriate personnel upon
completion. The water analysis requires an appropriate water sample to be taken and then sent to
EcoWater CHC for analysis. Follow the Water Sampling Procedure to secure appropriate water
samples. The water samples can be sent to EcoWater upon acquisition, or can be sent at the end of
the week for convenience.
White Rust- White rust is a corrosion of the galvanizing surfaces of a cooling tower. Unlike
normal scale, it will not dissolve in acid or Rydlyme and is very waxy in consistency. It also looks
like greasy ckicken pox covering a surface, because it is not consistent with a layer type scale over
tubes.
