Model CID-2S and CID-4S
The SWS CID Inactivates Cryptosporidium oocysts and Giardia cysts without chemical addition, filtrate disposal or production of harmful by-products
The SWS CID Inactivates Cryptosporidium oocysts and Giardia cysts without chemical addition, filtrate disposal or production of harmful by-products.

The SWS CID is a unique system incorporating advanced ultraviolet-based technology designed specifically to inactivate Cryptosporidium and Giardia in drinking water. These microorganisms are subjected to two treatment cycles each delivering multiple doses of UV irradiation at the necessary germicidal wavelength. System operation is electronically controlled and can be configured for remote monitoring.

Independent tests by two internationally acclaimed laboratories confirm the success of the machine. Test results, independent of flow rate, indicate greater than 4 log kill (>99.99% inactivation) with no viable oocysts detected.

KEY FEATURES

  • Unique In-Line System
  • Flow Rates up to 880 GPM(per machine)
  • Delivers Multiple Doses Independent of Flow Rate
  • Low Cost Solution
  • Adjustable Dosage Control
  • High Quality, Low Maintenance Components
  • Low Power Consumption -2.2kWh (for the CID-2S )
  • Integral Stand-By UV Lamps
  • Teflon Coated Quartz Sleeves Minimize Fouling
  • No Backwash Water or Harmful By-Products

SYSTEM DESCRIPTION:

Cryptosporidium and Giardia are pathogenic organisms often found in water. They are extremely resistant to inactivation by use of conventional disinfection, including chlorine. They are also difficult to inactivate with conventional UV systems due to the high dose required for inactivation.

These innovative machines have been designed for use in municipal and industrial water treatment processes, including point-of-entry applications. While specifically designed for inactivation of Cryptosporidium and Giardia, many other microorganisms will also be inactivated by this system.

Water enters the treatment chamber and passes through a specially designed filter screen. Cysts and oocysts are trapped on the screen and irradiated with germicidal wavelength UV. When the pre-set dose is achieved, the flow through the chamber is reversed and the organisms are washed off the screen and into the second chamber where the process is repeated until the pre-set dose is again delivered. The process is achieved on a continuous basis by using a series of automatically controlled valves. The change in flow direction ensures that debris does not accumulate on the screens. Screen condition is continuously monitored using differential pressure sensors.
