Flocculation Unit - W1

Allows the well known 'jar test' 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.

Filterability Index Unit - W4

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.

Deep Bed Filter Column - W5

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.

Model Sedimentation Tank - W7

Demonstrates 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 Digester - W8

Anaerobic Digester W8

Ion Exchange Unit - W9

Low cost, bench-mounted unit demonstrates the use of ion-exchange resins for either continuous water softening or demineralisation. Emulates the industrial operation of such units, including monitoring 'break-through' and regeneration cycles.
