In-situ electrochemical backwashing of attapulgite clay–based ceramic membranes for roof-harvested rainwater treatment

Key Points

• Electrochemical backwashing significantly improves the performance of ceramic membranes in rainwater treatment, enhancing filtration efficiency.
• Membrane systems employing attapulgite clay exhibited a reduction in fouling, ultimately improving longevity and effectiveness of treatment.
• Assessment using electrochemical techniques showed a notable improvement in reducing contaminants, leading to clearer water output.
• This method may enable more effective filtration systems for sustainable water management, with further validation needed for broader applications.
