Electricide CD2D and CD2C Acid-Chlorite Chlorine Dioxide Systems
|
|
Introduction
Acid Chlorite Reaction
The Electricide CD2D and CD2C acid-chlorite chlorine dioxide generators represent the highest quality, performance and accuracy available in 2 chemical acid-chlorite generators. The operation principle is as per the following reaction:
5NaClO2 + 4HCl → 4ClO2 + 5NaCl + 2H2O
Dilute Chemical Generators for Lower Capital Cost.
The CD2D generators utilize dilute 7.5% sodium chlorite and 9% hydrochloric acid and range in capacity from 40-800 g/hr (2.4 - 42.4 ppd). These chlorine dioxide generators are ideal for applications with low water flow and therefore small ClO2 dose and reactant chemical consumption.
Concentrated Chemical for Lower Running Cost.
The CD2C generators utilize commodity 31% sodium chlorite and 33% hydrochloric acid (and dilution water) and range in capacity from 150-10,000 g/hr (7.9 - 528 ppd). These chlorine dioxide generators are ideal for applications with larger water flow and larger ClO2 dose and reactant chemical consumption.
Chemical Supply. Chemical supply can be from bulk chemical storage tanks or drums/totes (1,000L IBC’s). Dioxide Pacific supplies the chemicals required and has stock at all locations:
Electricide 2D-C 7.5% sodium chlorite
Electricide 2D-A 9% hydrochloric acid
Electricide 2C-C 31% sodium chlorite
Electricide 2C-A 33% hydrochloric acid
Flexible purchase arrangements. Dioxide Pacific can provide the generator and dosing system as a capital purchase or under a rental agreement. Rental involves a fixed monthly fee to cover operation and maintenance of the plant. Ownership remains with Dioxide Pacific. One advantage of this method is that Dioxide Pacific is responsible for the ongoing performance of the plant.

Features
Wall mount backboard with Fiberstrut vinylester fixings for optimal chemical resistance. Easy to install with long life and resistance to corrosion.
Flow monitoring for dosing pumps. Chemical is always being dosed at the correct rate for the reaction. If one chemical has missing flow for x pulses, the generator is stopped and an alarm raised.
Inbuilt calibration cylinders. The generator can be accurately calibrated without operator exposure to either acid or chlorite. Just open and close a few valves for this procedure.
Pulse frequency controlled dosing pumps. Standard high quality metering pumps have power on all the time and are speed controlled via pulse frequency for accurate turndown of up to 200:1.
By-pass Dilution. By-pass assembly with rotameter, low limit switch and static mixer ensures even distribution of chlorine dioxide in by-pass flow and safe transportation of chlorine dioxide to the dosing point.
Inputs for chemical level switches (2 stage or 1 stage). Display of chemical level status on controller and warning if low, shutdown if empty
Touchscreen for flexible operation of plant including flow pacing, residual control or compound control. Display of operating status and faults
Optional remote internet access to plant. View the operating status of the plant, receive email alarms and start/stop plant items. This feature minimzes downtime and provides the ability to fault find without having to travel to site.
Optimized reaction chamber inside UPVC enclosure with vent connection. Maintains a safe working environment even in the case of a chlorine dioxide leak from the reactor.
Complete system assembled and ready for quick mechanical and electrical install. You can get running quickly to get benefit from your investment.

Critical Applications
Automatic Switchover
|
The CD2C-7R generator produces 1000 ppd (20 kg/hr) of chlorine dioxide and has inbuilt redundancy for critical applications. There are duty/standby dosing pumps for acid and chlorite, each with flow sensors. If one dosing pump fails, the other will automatically start to maintain continuous dosing. This generator is ideal for applications like potable water disinfection and frac water treatment.
Please download the CD2C-7R brochure for more detail.
