What is the performance improvement percentage for waste activated sludge with the addition of polymer in flotation thickening?

The performance improvement percentage for waste activated sludge with the addition of polymer in flotation thickening can be accurately identified through various studies and operational data. When polymers are added, they function as flocculants that enhance the bonding of particles, leading to increased particle size and improved settling characteristics.

In the context of flotation thickening, the addition of polymer typically results in a moderate improvement in the overall thickening efficiency. An improvement perceived as 1% indicates a measurable yet modest increase, often reflected in the operational conditions of the installation. This enhancement, while not monumental, can significantly impact efficiency in waste treatment processes and contributes to better overall sludge management.

Higher percentages than 1% may not be consistent with the expected results commonly observed in actual wastewater treatment scenarios involving flotation thickening with polymer aids, where the operational dynamics have limitations based on sludge characteristics and system design.
