The W1 enables 'jar tests' to be conducted on samples of water requiring treatment. The correct dosage conditions to remove colour and turbidity may be established on a laboratory scale as a prelude to full-scale plant operation.
The Armfield Sedimentation Studies Apparatus provides a facility for studying the basic physical processes involved in sedimentation, including zone formation and hindered settling.
The W3 is designed for students to measure and understand the characteristics of flow through a bed of particles. Such flows occur both naturally in certain ground water situations, and in process plant designs.
The W4 enables a water quality test to be conducted on a suspension to be filtered through sand or similar granular media. It can therefore be used in routine control at waterworks, or at a sewage treatment works which employs tertiary filtration.
