WTPRO404
RO 404 is a membrane cleaner based on a blend of food grade citric acid and other additives and is specifically designed to remove iron fouling. It is also effective against calcium carbonate scaling. The performance of RO 404 can be enhanced by the inclusion of RO 414 in the cleaning solution although some minor pH correction may be necessary.
RO 404 should always be used as recommended by the membrane manufacturer or equipment supplier, in respect to cleaning pH and temperature.

Cleaning solutions should be prepared with chlorine free product water to give a 4% w/w solution, or 1 kg of RO 404 to every 25kgs of water. As RO 404 is buffered the cleaning solution will stabilise at pH 3.6.
The cleaning time depends on the amount of fouling present but is usually completed within three hours. If the cleaning solution becomes red/brown in colour it must be changed as it has become exhausted. The RO 404 cleaning solution should always be discarded after use.
Avoid direct contact with skin and eyes to prevent mild irritation. In case of accidental contact, flush area with clean water. Product should not be ingested. Refer to Safety Data Sheet for full details.
