Membrane wastewater covers

Maintenance after a tank cover enters service depends on access planned in advance. Follow the routine inspection route when comparing proposals, checking observation, sampling and equipment-maintenance positions.

Openings may serve observation, sampling or equipment removal. Arrange them for the specific task rather than expecting one poorly located opening to serve everything.

  • Is there working space to replace a local membrane panel?
