DESIGN
& CONSTRUCT PROJECT
This new lime storage and dosing facility in central New South
Wales is an excellent example of turnkey contracting by Techniplan.
The plant was designed, manufactured and erected by Techniplan
personnel to a stringent performance specification required
by the New South Wales Public Works Department.

INNOVATIVE
MULTI DISCIPLINED DESIGN SOLUTIONS
Hydrated lime is a difficult material to handle and Techniplan's
design includes a mass flow bin, bin agitation unit, screw feeder,
water dissolution and slurry pump. The plant is fully automatic
and features state of the art weighing cells, and all electrical
interlocks, to ensure plant integrity and operator safety under
all conditions. Techniplan's modular construction technique offers
a cost effective alternative to the traditional construction methods.
PLANT OPERATION
Lime is accurately measured by a volumetric screw feeder and discharged
automatically from the 30 tonne bulk storage bin. The volume of
lime fed to the mixing tank is governed directly by a signal proportional
to the flow in the main water supply pipe. The lime powder is
mixed by an electric agitator operating in the mixing tank to
form a slurry which is then pumped directly to the main pipeline
by means of a positive displacement cavity pump.

LIME
STORAGE AND DOSING PLANT
Lime storage and dosing facilities were built for the ACT Electricity
and Water supply authority at Mt. Stromlo water treatment works.
The facility consists of a new 30 tonne storage silo for handling
bulk lime from road tankers. Two streams of lime are taken from
the silo and metered into intermediate holding hoppers. The
lime is then accurately dispensed from the intermediate hoppers
via volumetric feeders into mixing tanks where the lime is dissolved
in water. The concentrated lime slurry solution is then pumped
to the two dosing points in the water treatment plant. The system
is accurately controlled by a PLC using PH measuring devices
and flow pacing signals to determine the feed rates and dosing
rates.

LIME
STORAGE PLANT
Lime storage and transfer facilities were built for The Gold
Coast City Council at its Mudgeeraba water treatment works.
The facility consists of a new 30 tonne storage silo for handling
bulk lime from road tankers. A screw conveyor transfer system
feeds the lime from the new silo and distributes it to three
existing day hoppers. Three manual bag loading facilities were
constructed so that lime can now be accepted in 20 Kg bag form.
The contents of the silo are determined by weigh cells on the
hopper structure, with continuous read out of the level in the
water treatment plant control room. The silo and the three bag
loaders are equipped with a dust collection system providing
a clean environment for workers in the plant.

LIME
& ALUM DOSING
PLANT
Lime & Alum storage and dosing facilities were built for
Mackay City Council.
The facility consists of a new 30 tonne storage silo for handling
bulk lime from road tankers. A vibratory feeder transfers the lime from the silo and distributes it to two day
bins. A volumetric feeder transfers the mixed contents from an
agitator into the dosing point.
