Know what you’ll get, before it’s built
When you buy a car, you can see it in the showroom before you buy it. When it arrives, it is exactly as you had envisioned and there are no (nasty) surprises. With Dioxide Pacific, it’s the same with everything we build. It may be a standard product like our Electricide® chlorine/chlorine dioxide generators or a bespoke chemical dosing skid. Either way, we always produce a 3D model of the system using Autodesk Inventor, which becomes the template for our staff to build the item. Generally, we don’t produce 2D fabrication drawings as we find the 3D model is easier and more accurate to build from. When you order a system, you’ll be provided with the 3D model and the ability to view the model from different angles; parts transparent or hidden and measurement tools. You can ask for changes to be made at that time until you are happy with the layout. The built system will be exactly the same as the 3D model you have approved. It will fit in the space you have allocated and connect to services exactly as promised.
Dioxide Pacific recently designed and built a chemical dosing skid for sodium hypochlorite for an odour scrubber. The dosing skid is a powder coated stainless steel frame with Fiberstrut base, HDPE sides and a polycarbonate splash screen. Metering pumps ProMinent Sigma/3. All accessories including actuated ball valves, mag flow meter, pressure gauge and pulsaton dampener are fixed to the HDPE back using Fiberstrut bolts and pipe clamps.
The 3D model was developed from the P&ID and approved by the customer prior to fabrication.
When complete, the skid was tested at our works and delivered to site. Time frame from approval of the 3D model to delivery was 4 weeks. This short time frame was critical to the customer.

Background – Chlorine Dioxide Disinfection
Dioxide Pacific recently provided an Electricide CDE-25 (472 g/hr – 25 pounds per day) electrochemical chlorine dioxide generator and dosing system to replace a traditional 2-chemical generator utilising 33% HCL and 25% sodium chlorite. This Australian dairy processor treats four water streams from the one generator including mains water and condensate.
The 2-chemical generator had ongoing reliability issues, plant room corrosion from HCL fumes and reduction in water alkalinity (pH). After an extensive evaluation process by an external consultant, the Dioxide Pacific Electricide electrochemical generator was chosen as the preferred replacement.
The pertintent advantages of the Electricide generator are:
- Use of only one precursor chemical
- No acid – existing acid storage can be removed
- Lower reduction in alkalinity (reduction in caustic use for pH correction)
- Higher purity chlorine dioxide – no sodium, chlorite, chloride, chlorate added from the generator
- Production of consistent 2,000 ppm ClO2 solution for dosing
- Remote access via web server
In this system, chlorine dioxide solution at 2,000 ppm is produced in the generator solution tank and transferred via level control to a 1,500L FRP external storage tank. Four metering pumps dose from the outlet of this external tank to the four dosing points. Dosing is controlled from the generator HMI/PLC using different modes. There are three water storage tanks which are circulated. Each of the three tanks is controlled to a set ClO2 residual using PID control. One tank (mains water) also has flow paced dosing. Water entering the tank is dosed via flow pacing and the mains water in the tank is dosed to a PID setpoint. The combination of flow paced and PID provides accurate residual control.
Dioxide Pacific provided the complete system including generator, metering pumps, residual analyzers, chemical transfer system and storage tanks. Metering pumps with isolation valves, load valves, pressure relief valves and gauges were assembled on a skid. Analyzers and probe holders were mounted on a backboard. Electricide-P1 chemical is provided by Dioxide Pacific in IBC’s (totes). This chemical is formulated to provide chlorine dioxide conversion and long life for the electrolytic cell. The system was installed inside a purpose built shed by the customer.
Does this sound like something you could use?
Chlorine dioxide is ideal for disinfection of water used in food & beverage processing. You may be using chlorine or a 2-chemical chlorine dioxide generator for your water disinfection. If this information has piqued your interest, contact us for more information or a quotation.
