Chemical Cleaning Agent
ACCEPTA 2877 antifoulant is a non-acid blend of sequestering and dispersing agents for the removal of iron oxide, other metallic oxides and scale deposits from open and closed systems prior to commissioning with a suitable corrosion inhibitor. It may also be used continuously at low levels to prevent deposits forming. Iron oxide and other foulants deposited within in a system provide an environment for corrosion to take place, which inhibitors cannot protect against. Therefore it is vitally important that systems are cleaned and flushed properly beforehand. ACCEPTA 2877 is a safer alternative to ammoniated citric acid for precommission cleaning.
For precommission cleaning a concentration of 2-4% by volume should be used and circulated for a minimum of 2 days and a maximum of 7 days. For restoration cleaning a concentration between 5-10% is normally required, dependent on the degree of fouling. The length of time required to affect a clean will again depend on the degree of fouling and the progress of chemical reactions can be monitored by simple on-site test methods or by postal samples to the ACCEPTA Laboratory.
Whilst not aggressive to the parent metal ACCEPTA 2877 is a powerful penetrant and will find any weakness in pipework or joints which is simply sealed by a layer of corrosion products. It is recommended therefore that in the restoration of old systems that an initial concentration of 2% only be added and circulated for 2 days to ensure system is sound before proceeding further. When cleaning system containing Aluminum in conjunction with Copper a supplementary treatment ACCEPTA 2334 should also be added at the rate of 1 litre/m3 of system capacity.
Refill the system adding the required water treatment chemicals, for example, Accepta 2336 if no aluminium is present, or if the system has aluminium use Accepta 2309 as the scale and corrosion inhibitor for your closed circuit water systems.
