Walchem Takes Guesswork Out of the Disinfection Process
Assure Proper Disinfection with a Walchem WDIS Controller
RHFS offers the Walchem WDIS Series Controller to reliably and economically control
your water treatment disinfection processes. There are no reagents, and the user
may select from four sensor inputs: Free Chlorine, Chlorine Dioxide, Ozone and Peracetic
acid. Designed to be fl exible and versatile, the WDIS Series controller and complementary
sensors are an ideal disinfection solution combination for food & beverage, drinking
water & many food-processing applications.
Sensors are long-lasting amperometric electrodes with rugged membranes, featuring
integrated temperature compensation and large openings in fl ow cell to prevent
clogging. Controller features a probe wash relay mode to allow for automatic sensor
cleaning and/or continuous operation in harsh environments.
The WDIS Series controller continuously monitors the disinfection process, offering
precise control to the prescribed range required for proper system and regulatory
compliance. Display status at a glance without interrupting control. Outputs can
be confi gured as high or low set points via keypad. Auxiliary outputs may be set
as Hi or Low alarms, In-range output, Out-of-range alarm, and Probe wash.

Microza® Protects Against Water-Borne Contaminants
Conventional water treatment upstream of nanofiltration and reverse osmosis systems
can include sand filtration, flocculations, ion exchange resins and cartridge filtration.
For a more economical and reliable approach, Pall has developed a compact system
that uses Microza Hollow Fiber modules for the replacement of most conventional
water treatment steps upstream of reverse osmosis or nanofiltration. The modules
are available in Microfiltration or Ultrafiltration grades to meet the application
requirements.
Since membrane technology provides a positive barrier, the Microza LGV modules provide
a much higher security against waterborne contamination than traditional systems.
The hollow fiber membranes have low fouling characteristics and are mechanically
strong so that they can be backflushed to ensure stable operation. The quality of
the filtered water meets requirements and remains stable even if the raw water quality
is variable. The hollow fibers remove oxidized iron and manganese and organic contaminants.
They provide exceptional security for microbial contaminants such as molds, cysts
and viruses.
