Long-term Corrosion Control of Waste Water Treatment Tanks

After every good practice in repairing damages wrought by corrosion to wastewater treatment tanks have been observed and implemented – from proper survey and accurate assessment of the tank’s condition and extent of corrosion, to applying the most appropriate anti corrosive coatings – one last thing should be conscientiously implemented in the corrosion control project. Failing to implement this step will put all remediation efforts in vain.

This last, though not the least, important step is the setup of an effective system of continuous monitoring of the corrosion-prone sewage tanks. The offshoot of long-term monitoring is that this assures the existence of a remediation plan that can easily be implemented whenever an alarming level of corrosion damage has been reached. This means that the long-term good performance of any anti-corrosive coatings system is assured, and gains the treatment facility immense benefit in terms of sustainability.

Continuous monitoring, prompt detection and rapid implementation of a standby remediation plan are a good idea, because of the ever-present menace of corrosion in wastewater treatment plants. All those treatment chemicals in the area are a definite fuel for corrosion to take place anytime. The toxic environment calls for an SOP on periodic maintenance and repairs, a program that involves detailed surface preparation, anti corrosive coatings application, post-curing procedures, among others. In actuality, the cost of setting up this monitoring mechanism is more reasonable than the cost of repairing severe corrosion damage later on.
