The equipment is designed to allow the well-known '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.
Bench mounted and back lit for ease of observation, the unit provides a facility for studying the basic physical processes involved in sedimentation, including zone formation and hindered settling.
This apparatus is designed for students to measure and understand the characteristics of flow through a bed of particles. Such flows occur naturally and in process plant designs. It may also be used for a part of the testing of media for water and waste water treatment processes.
The unit enables a water treatment test to be made on a suspension to be filtered through sand or similar granular media. whilst developed as a teaching tool, it can also be used in routine control at waterworks, or at a sewage treatment works which employs tertiary filtration.
This laboratory deep bed filter column has been designed to operate identically to full scale granular filters. Using the same bed depth and filter media, tests on this unit provide operational data which may be scaled up to full size. Pilot trials of possible filter designs for water and sewage works can be made reliably at low cost.
This unit has been designed to demonstrate the hydraulic characteristics and settling efficiencies of a model settling basin. Although scale-up to industrial size sedimentation tanks is difficult, relevant deductions can be made as to how non-uniform flows occur and how these interact with the settling characteristics of particular suspensions.
Anaerobic treatment processes involve bacteria which function only in the absence of air. This digester is designed as a bench top training facility and as a means of providing operational process data for plant design purposes.
A low cost, bench mounted unit designed to demonstrate the use of ion-exchange resins for either continuous water softening or demineralization. The equipment is designed to emulate the industrial operation of such units, including monitoring "break-through" and regeneration cycles.
The purpose of this aeration unit is to permit the study of the oxygen transfer characteristics of diffused air systems and the physical and chemical parameters which influence their oxygenation capacity. These studies are a necessary prelude to the understanding of the biological treatment of waste waters.
The continuous activated sludge process has been successfully employed in public health engineering installations for nearly a century. The bench top aerobic digester is a comprehensive study facility of this biological water treatment process using a safe, synthetically prepared waste water.
