Polyring - KD 21

KD21 type polishing is used to add liquid polymer to the sludge prior to dewatering and is primarily used when the dry matter content exceeds 1%.

Advantages of using the poly ring include the ability to clamp it between two flanges, ensuring an easy and safe installation. In addition, it involves low investment costs and no operating costs.

The poly ring also ensures a homogeneous distribution of the polymer in the sludge and offers flexibility in placement and easy disassembly for cleaning.
