Chlorine Dioxide Precursor 20 for SafeOx Simplicity Generator

Chlorine Dioxide Precursor 20 for SafeOx Simplicity Generator

Accepta 8720 is an innovative formulation solution used to generate high purity chlorine dioxide using Accepta's high performance SafeOx Simplicity chlorine dioxide generating system.

Accepta 8720 is used inconjunction with Accepta 8708 (activator) and the SafeOx Simplicity generator.

Accepta 8720 is a unique product which through a controlled reaction releases the ‘active oxygen’ power of chlorine dioxide to disinfect and maintain the microbial quality of drinking, domestic and cooling water systems. It can also be used for odour control and to remove iron, manganese and sulphide from solution.

Chlorine Dioxide is an extremely effective anti-microbial agent which has significant advantages over traditional chlorine based biocides, but has to be handled with extreme care because of its toxic and potentially explosive nature. Accepta 8720 is a stable, easy to handle solution which when used in conjunction with the SafeOx Simplicity generator system provides all the benefits of chlorine dioxide with none of the problems.

When compared with any other means of generating chlorine dioxide the SafeOx Simplicity generator system is the only system which can provide instant activation and total control.

Benefits of Chlorine Dioxide v Chlorine

Chlorine Dioxide Chlorine
No taste or odour Taste and odour problems
Does not form chlorinated by by-products Forms trihalomethanes
No reaction with nitrogen containing compounds Produces Chloramines
Unaffected by pH Reduced effectiveness at high pH
Penetrates and disperses biofilms Little effect on biofilms

Application & Dosage Information


The biocidal power of Accepta 8720 only becomes available on reaction with the system activator, Accepta 8708 chlorine dioxide release agent.

Where continuous dosage is required a SafeOx Simplicity chlorine dioxide generating system should be used.

Disinfection (dosage rates)

Storage tanks and domestic water services should be disinfected using 1.25L/m3 of system volume Accepta 8720 and a similar volume of Accepta 8708. The system should be left for a minimum of one hour before flushing out.

Alternatively for large tanks spray disinfection may be employed using a solution containing 5L/m3 of Accepta 8720 and Accepta 8708.

Cooling towers and evaporative condensers should be disinfected by maintaining 25ppm of chlorine dioxide in re-circulation for a period of one hour before and after cleaning.

Accepta technical support can advise on the correct procedure.

Continuous Application

The quality of drinking water can be maintained by continuously dosing Accepta 8720 and Accepta 8708 to provide a maximum concentration of 0.5ppm total oxidant as chlorine dioxide at outlets of the system.

Accepta technical support can advise on the correct dosage levels.

For non-drinking water applications such as domestic hot water services dosage rates may be increased to provide increased protection against Legionella Pneumophila.

Cooling towers and evaporative condensers should be dosed to maintain 0.2 to 0.5ppm chlorine dioxide in re-circulation. The residual oxidant level can be easily monitored with a simple Accepta test.

It is recommended that in all continuous dosing applications a SafeOx Simplicity generator system is used to ensure the correct application and maximise the benefit of this innovative product.

It is always advisable to carry out a 'Control Of Substances Hazardous to Health' (COSHH) assessment before use.
