MKK Swing Disk Screen

General Description

MKK developed the Swing Disk Screen to separate and remove impurities and other foreign materials in a continuous process from the waste water and sewage sludge and scums formed in the treatment of sewage. The conventional screens have suffered from clogging by hair, cotton waste and other fibrous material and they are also considered unsuitable for use in the primary settling tank due to its a high concentration of solid matters. Thanks to its unique design, MKK's Swing Disk Screen overcomes these shortcomings.
