Treatment of oil at the bottom of the electrodialysis tank
Thread Content
Gentlemen, the electrodialysis system in my workshop has been in operation for three years; it has now stopped working. Upon inspection, it was found that there was severe sludge accumulation at the bottom of the electrodialysis tanks. Backwashing was carried out regularly during the operation of the system – what could be the reason for this?
Check the procedures and follow them strictly to carry out maintenance
The backwashing orientation is inappropriate, failing to achieve the desired effect. After opening the can, you can turn on backwashing to check for any issues.
The backwashing intensity is insufficient, resulting in sludge accumulation; this is a problem present in every petrochemical plant, and the electrodialysis manufacturers need to make corrections
