The main dry substance used in the treatment of potable
water is powdered activated carbon for the reduction and
adsorption of contaminants. For each application Wallace
& Tiernan has a suitable dosing
unit for activated powder carbon: The JETPAK is suitable
for up to three points of application for which a powdered
activated carbon suspension of 20 or 40 g/l is prepared.
The amount added can be adjusted separately for each point
of application.
The BIGBAG is suitable for larger quantities – with
discharge agitator and flexible screw conveyor.
Wherever lime is employed for neutralisation purposes
and used as lime milk, Wallace & Tiernan lime slakers
come into action.
In addition Wallace & Tiernan manufactures customised
dosing equipment for dry chemicals of all types, such
as hydrated lime or aluminium sulphate. Wallace &
Tiernan manufactures special compact preparation and
dosing systems for polyelectrolytes which are used as
flocculants.
