The Electricide^® chlorine generator can replace gas chlorine storage for potable and process water disinfection. Does the safety risk of storing liquified chlorine gas in 70kg cylinder or 920kg drums concern you? The Electricide^® chlorine generator removes this risk, by generating chlorine on-site and on-demand. Chlorine is not stored, but is an intermediate product: generated then immediately dosed. The only chemical stored is the precursor. The generator can be configured to use either granular salt (NaCl) or a purified brine solution: Electricide-B1. Both precursor forms are easy to transport, store and handle with no safety risks. No connection of cylinders or drums by operators. No unloading of cylinders or drums from trucks.

For replacement of existing gas chlorination systems, the existing booster pump, eductor and chlorine leak detector can be reused, reducing the retrofit cost.

Our generators are CE marked for operation in Europe

Many sites are managing frequent deliveries of bleach (commercial sodium hypochlorite) from tankers into bulk storage tanks. There are safety risks associated with unloading, storage and dosing of this chemical. Commercial sodium hypochlorite (12.5%) undergoes degradation to oxygen and chlorate with the speed of degradation related to temperature, pH, concentration and impurities.  In the graph below, the yellow line is degradation of 12.5% sodium hypochlorite and the blue line is degradation of electrolytically generated 30 g/L sodium hypochlorite. 12.5% sodium hypochlorite is reduced to half its original concentration in 20 days, whereas the 30 g/L solution has virtuall zero degradation in 90 days.

Typical 12.5% (125 g/L) sodium hypochlorite comes immediately from the manufacturer with 1.5 g/L chlorate ion present.

The Electricide^® chlorine generator produce sodium hypochlorite solution at 2-30 g/L, pH 10 and low in sodium, chloride and chlorate. It is lower in sodium and chloride than other electrochlorinators because chlorine gas is generated, extracted with air, redissolved into caustic catholyte and is very stable in storage.

Some of our customers are located in remote areas where sodium hypochlorite is expensive to purchase or deliveries are unreliable. The bleach supplier will often require large bulk tanks to be installed to ensure low frequency of deliveries. This is a problem because bleach degrades in storage and at the middle-end of the tank volume, hypochlorite concentration is low and chlorate concentration is high. The Electricide^® generator is a flexible source of sodium hypochlorite as it makes the chemical, fresh, as required.

For sites that have an existing bulk tank for 12.5% sodium hypochlorite, the Electricide^® generator can be installed to top up this tank and therefore, tanker deliveries will cease.

Chlorine Generation Reactions:

① Anode (oxidation): 2Cl^– → Cl₂ + 2e^–

② Cathode (reduction): 2H₂O + 2e^– → H₂ + 2OH^–

① + ② (combined) 2Cl^– + 2H₂O → Cl₂ + H₂ + 2OH^–

 

In the Electricide^® HG Generator, chlorine gas reacts with caustic catholyte to form sodium hypochlorite and salt.

Cl₂ + 2NaOH → NaCl + NaOCl

The key benefits of the Electricide^® generator are the use of only one precursor chemical, highest safety and lowest running cost. Another important feature is remote internet access for validation and troubleshooting. For a full list of features and benefits, download the HG Electrochemical Chlorine Generator Brochure

  HG Series Electrochemical Chlorine Generator (3.5 MiB)

Dioxide Pacific offers the the Electricide^® generator as a complete package including granular salt or purified brine: Electricide-B1 precursor and maintenance. Remote internet access enables viewing of generator operation at any time and from any location via an internet browser – to just check the system is operating correctly, make an adjustment to a setpoint or reset an alarm. PLC or HMI program changes can be made without having to attend site. Remote internet access adds up to lower maintenance costs for you. Why send a technician to site when there is no need for it! Dioxide Pacific provides a huge library of “how to” technical and training video resources for your use, all accessible from our website. For instance, we have videos for: “how do I test the performance of the electrolytic cell”; “how do I test chlorine dioxide strength”; “how do I replace a metering pump”. In most cases, you can safely perform maintenance on the generator without involving our technicians. If you would prefer Dioxide Pacific to handle some or all of the maintenance, of course we can provide technicians for this.

How is chemical supplied?

Granular salt comes in 20 kg = 50 lb bags. Purified brine: Electricide-B1 can be supplied in drums or IBC’s (totes). Granular salt and Electricide-B1 are not hazardous chemicals and specialised spill containment is not required.

Dioxide Pacific offers turnkey systems including design drawings (P&ID, 3D model and GA), installation (mechanical and electrical) and commissioning. Our quality project management system ensures the plant will be installed on time with the smallest possible interruption to your site. We have proven risk management protocols written specifically for chlorine dioxide systems to ensure that installation, commissioning, training and operation of the plant is extremely safe.

Electricide^® Chlorine systems can be installed in dedicated plant rooms, skids for transportation to remote sites or in portable buildings.
