Organic Acids & Dispersing Agents for Iron Oxide Removal

Organic Acids & Dispersing Agents for Iron Oxide Removal

Accepta 0023 is a high performance treatment for metal surfaces based on a blend of organic acids and dispersing agents scientifically formulated for the removal of iron oxide deposits on industrial pipework and heat exchangers.

Application & Dosage Information

Accepta 0023 is an effective cleaning material in the cold although the application of heat increases the rate of reaction.

Circulation of the water / product mixture increases the effectiveness of the cleaning. 

Where the system is badly fouled, several days may be necessary before the system can be drained. Alternatively a continuous bleed-off from the system can be employed if system downtime cannot be allowed.

The precise dose rate and length of recirculation will be advised by our technical consultant.

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

Existing Systems

Accepta 0023 is an effective cleaning material in the cold although the application of heat increases the rate of reaction.  It should be diluted with water before use to give a 2.5% to 10% solution, depending upon the quantity of iron oxide present in the system. 

Light rusting will be removed after 24 hours. 

Circulation of the water / product mixture increases the effectiveness of the cleaning. 

Where the system is badly fouled, several days may be necessary. 

After five to six days circulation most reaction can be considered to be complete and the system should be flushed out. 

Only occasionally will it be found necessary to repeat the cleaning process.

New Systems

For pre-commission cleaning the product strength in the system can be reduced to 1%.  A contact time of 24 hours is usually sufficient.

Control

Treatment performance is controlled by monitoring soluble iron levels in the system water and making any additional treatment doses as required.
